Design Philosophy 2.SafeRing and SafePlus – ABB switchgears for secondarydistribution

Evolution: - more functionality,smaller dimensionsSecondary distribution switchgears have been subject to asignificant development the recent 20 years.

The traditional switching cells are substituted with completeswitchgear systems. Specific functions as grounding, disconnect-ing, cable connections, busbar extension, protection andswitching have become integrated features in compact functionalunits.

Compact switchgear systems catered for customers MV applica-tion needs. ABB has always been a part of this development.

The current ABB SafePlus range satisfies the most complexsystem specifications.

The most unique specialisation is the development of the cablering switchgear. The numerous public distribution substationsrequested a unified switching functionality that evolved into theRing Main Unit concept. ABB SafeRing range is one major contributor to this specialisa-tion.

Two Products – One rangeABB SafeRing is adapted to the needs in the immense utilitydistribution network.ABB SafePlus offers more in terms of flexibility and electricalcapacity.Both switchgears offer the same customer interface.

Customers involvement:The applied functionality in ABB SafeRing and SafePlus is aresult of input from customers all over the world.

Key customers are continuously involved with ABB design staffto ensure optimised switchgear operation. The functionality willalways find its background from customer demands.

Electrical and mechanical capability results from more than 100years of ABB development.

Personnel – safety and serviceSafety is not only a specification and rating issue, but also a reallife experience.Standards and associated testing will disclose weakness at timeof testing. ABB takes this further to be an objective related todurability and repetitive manufacturing quality.

All products are manufactured in accordance with ISO 9001.Thelatest edition of relevant IEC standards will always apply to ourcontinuous test programme.Features for further enhancing personnel safety are available.

“Integrated functionality” is a key objective to reduce the numberof moving components, further reducing the risk of any mechani-cal defect.

Design Philosophy 2.

We are responsible for the environmentThe location for manufacturing SafeRing and SafePlus is Norway.Norway’s green policy contributes to focus on environmentalfactors in manufacturing as well as over the switchgears life span.

All products are manufactured in accordance with our ISO 14001certification.Recycling is confirmed at a 97% level.To simplify this process we will continuously along with our part-ners develop routines for handling at end of life.Plastic parts are individually marked to simplify the recyclingprocess.

Solutions for elimination of gas emission in the rare event of a faultcan be supplied.

Modern - development and manufacturingNumerical simulations together with long experience will ensurecompact and robust design.

Dielectric simulations will ensure that compactness will not influ-ence the dielectrical capability.

The combination of design techniques, experience and the mostmodern production technologyguaranteestate of the art productsand durability.

Complete solutions – one supplierComplex applications involving remote control and monitoring cannow be supplied from one supplier.

This makes large scale implementation feasible, and will simplifyengineering and procurement.

The control and monitoring unit available for SafeRing is locatedbehind the front cover. This option is also readily available forretrofit, while such demands normally evolve after the switchgear isin service.

Industrial ITSafeRing and SafePlus are certified products according to "level 0:Information" in the Industrial IT architecture concept of ABB.

Industrial IT describes the ABB group commitment to bridging thegap between industrial assets and the information technology (IT)needed to make them work seamlessly together in real time.

Industrial IT "level 0: Information" certified products must have allrelevant product documentation - including the operation manual,instructions for installation and maintenance, electrical andmechanical drawings, test reports and order information availablein electronic format for access via software products and systemsbased on the ABB Aspect integrator Platform.

Covers

Upper and lower front cover have a thickness of 3 millimeteraluminium which is covered with a polycarbonate foil. These foilscontain the mimic diagram of the main circuit with the positionindicators for the switching devices. Background colour for thesefoils are RAL 7012. The upper front cover is removable. Thelower front cover can be opened.

There are four different cable compartment covers; standard, withinspection window, arc proof and finally one with extra depth forparallel cables.These covers are manufactured from 1.25 millimeter aluzink (notthe arc proof cover) and are powder painted with colour RAL7035.All cable compartment covers are removable. Each module has aseparate cable compartment that is divided from the others bymeans of partition walls. Also these partition walls can easily beremoved, allowing a comfortable access for connection ofcables.

A vertical partition wall is fitted to divide the cable compartment(s)from the rear side of the switchgear / ring main unit.In case of an arc fault inside the SF6 tank, followed by anopening of the pressure relief in the bottom of the tank, thispartition wall will prevent the hot gases blowing out from thepressure relief to enter the cable compartments.

Side covers are made of 2 millimeter hot rolled steel and powderpainted with colour RAL 7035.

The cable switch (C-Module) is a three positioningswitch-disconnector and earthing switch usingSF6 gas as an arc quenching medium.

The switch positioning are close – open – earthed. In theopen position the switch satisfies the disconnectorrequirements.

Cable Switch Module 5.2

C-module equipped with arc suppressor (optionalequipment) and cable test bushings(optional equipment).



CSG / RMU

The vacuum circuit breaker (V-Module) uses vacuum bottles asinterrupters of the current. In series with the circuit breaker main circuit is connected athree-position disconnector earthing switch which is identical tothe cable switch except the switch has no interrupting capacity.

The operation between vacuum circuit breaker anddisconnector/earthing switch is mechanically interlocked.

Vacuum Circuit Breaker Module 5.3



CSG / RMU Fuse Switch Module 5.4

The Fuse switch (F-Module) has a three positioningswitch disconnector and earthing switch identical to thecable switch.(C-Module)

By means of the fuse tripping device it operates as aswitch-fuse combination. There is a double earthingswitch which in the earthed position connects earth toboth sides of the fuses simultaneously.

Both earthing switches are operated in one operation.The fuse switch and earthing switch is mechanicallyinterlocked to prevent hazardous access to the fuses.

The lower cover which gives access to the fuses is alsomechanically interlocked with the earthing switch.

The connection of the HV-cable is made by cable bushings.The bushings are made of cast resin with moulded inconductors.In addition, a screen is moulded in to controlthe electrical field and is also used as the main capacitorsupplying the voltage indicators.

ABB has produced bushings for SF6 switchgears since 1985.

A very high number of units have been installed worldwide ondistribution networks, power stations and industrial complexes.

Used together with full-screened connectors an ideal solutionfor areas with a history of humidity or condensation problems isachieved.The bushings are designed according to DIN 47636.

There are 5 different cable bushings:- 200 series with plug-in contact (In=200A)- 400 series with M16 bolted contact (In=630A)- 400 series with M16 bolted contact and integrated voltage and current sensors (In=630A)- 400 series with plug-in contact (In=400A)- 600 series with M16 bolted contact (In=630A)

CSG / RMU

The Arc Suppressor is an optimal quick-make short circuitdevice with a mechanical pressure detector that can beinstalled with each incoming feeder inside the sealed SF6tank of the SafeRing and SafePlus switchgear.

If an arc fault should occur inside the SF6 tank the pressuredetector of the Arc Suppressor will automatically trip theshort circuit device of the incoming feeder(s) withinmilliseconds, thereby transforming the arc fault into a boltedfault.The arc is extinguished without any emission of hot gasesand the bolted short circuit will be interrupted by theupstream circuit breaker.

No links or release mechanisms are installed outside the tank.Corrosion and any enviromental influences are thereforeprevented, giving optimum reliability.

The pressure detector is insensitive to pressure changesdue to variation in atmospheric temperature or pressure aswell as external phenomena such as vibrations or shocks.

The arc suppressor will operate for short-circuit currents inthe range of 1kArms to 21kArms and it will reduce thegenerated arc energy to less than 5% of the arc energyreleased during an arcing time of 1 sec.

A signalling device (1NO) will indicate local or remote thetripping of one or more arc suppressors.

Since the system is self-contained, an internal arc fault willhave no impact on the surroundings. No arc fault tests have tobe repeated in combination with channel release systems ortransformer stations.The costs of the cleaning work which has to be done after aninternal arc fault when the release flap has opened, arereduced to zero.

Arc Suppressor 5.6



CSG / RMU

SafeRing/SafePlus are switchgears types using gas SF6(Sulfur hexafluoride) as insulation and quenching medium.The SF6 is contained in a welded stainless steel tank.

The pressure system is defined as a sealed for life system with anoperating life time of 30 years. The leakage rate is less than 0,1% peryear.

In order to guaranty a reliable and tight welding, all welding work is carriedout by computer controlled robots.Electrical and mechanical bushings penetrating the tank are clamped andsealed to the tank by high quality O-rings.

The mechanical bushing has in addition a rotating shaft which connect theshaft of the switch to the corresponding shaft of the mechanism.The rotating shaft is sealed by a double set of gas seals.

All SF6 tanks have to pass a leakage test, before gas filling. Leakage testand gas filling are done inside a vacuum chamber. The first step in theleakage test is to evacuate all air inside both SF6 tank and vacuumchamber simultaneously. Then SF6 tank is filled with Helium.

Due to the characteristics of Helium this test will detect absolutely allpossible leakages. If the SF6 tank passes this test, the Helium has to beevacuated and replaced by SF6.

The SF6 tank has a degree of protection of IP67.This means the SF6 tank can be immersed into water and still maintain allfunctions in a satisfactory way.

CSG / RMU Cable Test Bushings 5.8As an option, both C and De modules can be equipped with cable testbushings situated behind the lower front cover.This cover can be interlocked against the earthing switch to avoid access tothe cable test compartment before earthing switch is in closed position.

When these bushings are mounted, cable insulation test can easily be doneaccording to the following procedure:

Principle sketch for testing:

1. Close the earthing switch after having checked thevoltage indicators

2. Open compartment cover

3. Install the injection device onto the access terminals

4. Open the removable earthing bridge

5. Perform cable testing

6. Re-install the earthing bridge

7. Remove the injection device

8. Close compartment cover

9. Open the earthing switch

If the switchgear is not equipped with cable test bushings,cable testing is possible directly at the cable connectors ifthey are designed for this purpose, please follow thesupplier's instruction.

Removable earthing bridge



CSG / RMU

Padlocking device

Position indicator

All operating mechanisms are situated outside the SF6 tank behindthe front covers with degree of protection of IP2X.

This gives the opportunity of easy access to all operatingmechanisms if retrofit or service should be required. The speed ofoperation of these mechanisms are independent of the operator.

To prevent access to cable compartment before earthing switch is inclosed position, all mechanisms can as an option be supplied withmechanical interlocks which make it impossible to remove the cablecompartment covers. It will then also be impossible to operate earthing switch to openposition before cable compartment cover is mounted properly.

Each mechanism is equipped with a padlocking device. When addinga padlock to this device, the access to operate the mechanism will beimpossible. This device has three holes with diameter 9 millimeter.

All operating mechanisms are equipped with position indicators for allswitches. In order to achive true indication, indicators are directlyconnected to the operating shafts of the switches inside the SF6 tank,please see shafts shown with red colour on next page.

Operating handle has an anti-reflex system which prevents animmediate re-operation of the switch.

All steel parts have been electroplated with zinc and and then olivechromated.

Mechanisms and Interlocks 5.9



CSG / RMU

Fuse switch module (F-mechanism)The mechanism (3PAE) has two operating shafts; the upper one for the load breakswitch and the lower one for the earthing switch.The upper one operates two springs; one for closing and one for opening. Bothsprings are charged in one operation. By means of mechanical push buttons it isthen possible to close and open the load break switch.The opening spring is always charged when the load break switch is in closedposition and will then be ready to open the load break switch immediately if one ofthe HV fuses blow.The blown fuse(s) has/have to be replaced before the operator will be able to closethe load break switch again. According to IEC Publ.282-1, all three fuse linksshould be replaced, even if only one or two have operated.

The lower shaft is single spring operated. Both operating shafts operate onecommon shaft which is directly connected to the three position switch (CFE-F)inside the SF6 tank.

Due to the mechanical interlock between the upper and lower operating shaft, it isimpossible to operate the load break switch when earthing switch is in earthedposition or operate the earthing switch when the load break switch is in closedposition. It will also be impossible to get access to the fuse compartment before earthingswitch is in closed position.

Vacuum circuit breaker and Busbar sectionalizer with circuit breaker(V-mechanism)These two modules have two mechanisms; the upper one (2PA) with one operatingshaft is for circuit breaker and the lower (3PKE) one with two operating shafts is fordisconnector and earthing switch.The upper mechanism has two operating springs; one for closing and one foropening.Both springs are charged in one operation. By means of mechanical push buttons itis then possible to close and open the circuit breaker.The opening spring is always charged when the circuit breaker is in closed positionand will then be ready to open immediately if the protection relay gives a tripsignal.

However a quick reclosing is not possible. If the mechanism is equipped with amotor operation a reclosing will take approx. 10 seconds.

The lower mechanism is identical to the one described above for Cable switchmodule.

There is a mechanical interlock between these two mechanisms which preventsoperating of the disconnector and earthing switch when the circuit breaker is inclosed position. When the earthing switch is in closed position it will be impossible to operate thedisconnector, but the circuit breaker can be closed for testing purpose.

Cable switch module and Busbar sectionalizer with load break switch(C-mechanism)The mechanism (3PKE) has two operating shafts; the upper one for the load breakswitch and the lower one for the earthing switch.Both shafts are single spring operated and operate one common shaft which isdirectly connected to the three position switch (CFE-C) inside the SF6 tank. Whenboth load break switch and earthing switch are in open position, the switch satisfiesthe specifications of disconnector.

Due to the mechanical interlock between the upper and lower operating shaft, it isimpossible to operate the load break switch when earthing switch is in earthedposition or operate the earthing switch when the load break switch is in closedposition.

CSG / RMU External Busbars 5.10

On the top of all SafeRing and SafePlus switchgears it ispossible as an option to have bushings for connection ofexternal busbars on the leftmost and the rightmost module.

For a SafePlus switchgear consisting of only one module (whichis both leftmost and rightmost in one module), only one set ofbushings on the top is necessary.

When bushings are mounted on the top, you will have thesepossibilities:

1. When adding a dead end receptacle to each of thesebushings, SafeRing/SafePlus will be prepared for futurebusbar extension.

2. With a special designed external busbars kit, it will bepossible to connect two or more sections.

Since a 5-ways switchgear is the maximum size within onecommon SF6 tank, the busbar kit allows a configurationwith more than 5 modules.

The installation of the external busbars has to de done onsite, see separate manual for installationinstructions,NOPOWSP 6006 GB.

SafePlus prepared for future extension on right hand side

SafePlus switchgear can also be configured fully modular. Thisgives 1250 A busbar rating.

The busbars between the modules and the end adapters usedon the leftmost and rightmost module are identical to the partsused in the previous example. For the three modules in themiddle a special cross adapter is used.

All external busbars have identical lengths except those usedfor extension between a Metering module with a switchgear onthe right hand side.

CSG / RMU Base Frame 6.1When SafeRing or SafePlus are placed directly on a floor,there will be a height of 595 millimeter up to the centre ofthe cable bushings.If cable trench is missing, the height might be too low. It isthen possible to put an additonal base frame between thefloor and the switchgear.

This base frame is available in two different heights; 290and 450 millimeter.

When using the one with 290 millimeter height, it will givethe same height as our previous switchgear type RGCwhen it was mounted on a standard RGC base frame.

Inside the standard cable compartment for the vacuumcircuit breaker it will be enough space for three currenttransformers for protection purposes.

If an earth fault transformer or an extra set of currenttransformers are required, an additonal base frame isnecessary, please see examples on left hand side.

If motor operation, coils, auxiliary switches, self powered protection relayetc. are mounted on a SafeRing or SafePlus module, the terminal blocksand the wiring are located behind the front covers.

However, an additional top entry box can be mounted on the top of allSafeRing and SafePlus switchgears. Since the top entry box is fixed tothe side covers of the SF6 tank, the total width of the switchgear mustbe covered.

The top entry box allows entrance of the customer’s low voltage wiringfrom the rear side, left hand side and right hand side.

Further the top entry box gives the opportunity to install ammeters withposition switches, local/remote switch for motor operation etc.

Additionally all SafePlus switchgears can be supplied with low voltagecompartment.This compartment may be equipped with protection relays, meters,position switches, terminal blocks etc.

The compartment is fixed to the side covers of the SF6 tank and mustcover the total width of the switchgear.However, each module has a separate hinged door but there are nonepartition walls between the modules.

CSG / RMU Motor Operation 6.4Closing and opening operations of load-break switches and charging of the springs of the mechanisms for the circuit breaker and the switch-fuse combination may be performed with a motor operation.Disconnector in the V-module and all earthing switches do not have this possibility.

All motor devices require DC voltage. If control voltage is either 110 or 220 VAC, a rectifier is integrated in the control unit.

Operating cycle for motor operation is CO - 3 min (i.e. it may be operated with a frequency of up to one close and one open operation everythird minute). Motors and coils can easily be mounted to the mechanisms after delivery (retrofit).

Test voltage for tables below is + 10/ - 15 % for motor operations and closing coils and +10/ -30% for trip coils and opening coils.

Both for SafeRing and SafePlus the relay is a selfpowered relay that utilizethe energy from the CTs under a fault situation, for energizing the trip coil.

The self powered relay can also be used for cable protection and moredetails on the different relays can be found in chapter 6.7.

Transformer protection with selfpowered relay.Recommeded types:

- MPRB 99-1.0-GF- SACE PR521- SEG WIC 1

Important features V-module:- Relay behind cover. It’s not necessary with any additional low voltage boxfor the selfpowered relays used for transformer protection.

Typical for vacuum circuit breaker protection:- Good protection for short circuits- Very good for protection of overcurrents- Small fault currents are detected in an early stage.

CSG / RMU Ronis Key Interlocks 6.11

As an option all load break switches except the one for switch fuse module, earthingswitches and disconnectors may be equipped with Ronis key interlock type EL11AP.Ronis may be mounted according to the customer’s specification; either to preventclosing or opening of the switch.

Ronis key interlocks can be used as follow: Two switchgears A and B are connected toeach other by cables. The purpose of interlocks is to prevent closing of the earthingswitch unless the load break switch on the other switchgear is locked in open position.

1) One Ronis key interlock will be mounted close to the operating shaft of the loadbreak switch in switchgear A. An identical Ronis key interlock will be mounted close tothe operating shaft of the earthing switch in switchgear B. As long as the load breakswitch in switchgear A is in closed position, it will be impossible to remove or operatethe key in the key interlock.

2) First you have to operate this load break switch in switchgear A to open position.Then it will be possible to operate this key interlock and turn the key which extends thelocking bolt. This will prevent the access to the operating shaft of this load break switch.The next thing to do then is to withdraw the key and insert it into the identical keyinterlock on the earthing switch of switchgear B.

3) When the key is inserted, you will be able to operate the key interlock and turn thekey which will withdraw the extended locking bolt.

Then there will be access to operate this earthing switch to closed position. As long asthis earthing switch is in closed position, the key will be captured and makes it impossi-ble to close the load break switch in switchgear A.

4) If the load break switch in switchgear B and earthing switch in switchgear A areequipped with another identical Ronis key interlock which has a different keycombination than described above, it will be impossible to make an earth connection ofan incoming energized cable from neither switchgear A nor B.

Another example for use of Ronis key interlocks is to prevent access to the distributiontransformer before the primary side of the the transformer is connected to earth. Thiscan be solved by means of two identical Ronis key interlocks; one mounted on theearthing switch for the distribution transformer feeder and the other one on the door infront of the transformer.
