Predominant Vacuum Technology
SecoVac 01
Vacuum switching technology is nowadays the dominant switchingprinciple in medium voltage. Innovative developments are leading to acontinuously increasing market growth, based on the fundamentaladvantages such as reliability, availability, compactness and, last but notleast , the environmental friendliness of the vacuum as a switchingmedium.
Vacuum Interrupter
The switching element of the vacuum circuit-breaker is the vacuuminterrupter. It consists of an arc chamber, which is located between twoceramic insulators. Terminal studs connect the contacts to the externalterminals. One contact is fixed within the housing, the other one ismoveable. The metal bellows enable the contact movement and provide ahermetic connection to the interrupter housing. The contact stroke is onlya few millimeters. The internal pressure in the vacuum interrupter is lessthan 10-7 bar. The vacuum circuit-breaker has no arc-quenching medium.The properties of the contact material and the contact geometry definethe switching behavior and the switching capacity.
After contact separation, the resultant arc evaporates contact materialfrom the contact surfaces. The arc current thus flows throw a materialvapour plasma until the next current zero. Near the current zero, the arc isextinguished, and the metal vapour looses its conductivity within a fewmicroseconds as a consequence of the recombination of the chargecarrier ions. In this way, the contact gap is de-ionized and the dielectricstrength restored very fast. The metal vapour condenses on the contactsurfaces. Only a very small portion condenses on the arc chamber wall.The arc chamber wall has the function of a vapour shield, to preventcondensation of the metallic vapour onto the insulators
Automatic Pressure Gelation
A special cushion layer made of high insulation, gas tight and strong elastic material was employed around the surface of the ceramic tube of vacuum interrupter before it was embedded, so the cracking is thoroughly avoided.
SecoVac is the first completed series MV embedded pole vacuum circuit breaker in the world which employs the latest and mature technology of Automatic Pressure Gelation (APG) to embed the vacuum interrupter and connection terminals within epoxy resin. Compared with complete air insulated vacuum circuit breaker or assembly pole vacuum circuit composite insulation, SecoVac is of solid insulation, on one hand, the risk of insulation fault caused by adverse operating environment such as dust, humidity and small animals are eliminated thoroughly, so SecoVac is a vacuum circuit breaker with high environmental resistance. On the other hand, thanks to the embedded pole design, the distribution of electrical field of the pole is much even than that in the assembly pole vacuum circuit breaker, so the insulation strength is improved dramatically.

Embedded poles
Vacuum interrupter has extremely high internal dielectric strength resulting from the ULV while the external dielectric strength is however limited by the insulation capacity of the air, therefore also requires embedding the chamber in a solid material, In such cases, the vacuum interrupter is additionally well protected against external mechanical influences such as impacts.
The main advantages of embedded poles are high dielectric strength without additional external compensation in air, usability in an extremely wide range of climatic conditions, and good protection of the vacuum interrupter from dust, mechanical impacts and moisture. On the operating mechanism side, it is equipped with modularized, standardized and simplified spring mechanism, the whole spring mechanism is made up of separated closing and opening modules which can be preassembled and easily replaced on-site of end-users without any changing of the original dynamic characteristic of the breaker, so the lead time for delivery and down time for maintenance will be shortened.

SecoVac series MV embedded pole vacuum circuit breaker uses the latest and mature technology of Automatic Pressure Gelation (APG) to embed the vacuuminterrupter and connection terminals within epoxy resin. The vacuum interrupter is cast in the epoxy resin, so inside the epoxy resin there is no screw fixationthat will cause the concentrated harsh electrical field inside the epoxy resin and will consequently result in decrease of the electrical insulation strength of thepole. Thanks to the embedded pole technology, the assembly of the pole is simplified, and the assembly accuracy as well as quality of the embedded pole iseasily to be controlled by the state of the art production process. The embedded pole technology also obviously improve the environmental resistantcapability of the breaker, as the primary circuit of the breaker is completely embedded inside the epoxy resin, the risk of insulation fault caused by adverseoperating environment such as dust, humidity, ingression of small animals, polluted ambient and high altitude operating site are eliminated thoroughly.
The key know how of the embedded pole technology is the buffering layer betweenepoxy resin and ceramic housing of vacuum interrupter, the material and processingof the buffering layer is essential to ensure the integrity of epoxy resin of theembedded pole provide adequate adhesion between each other in any circumstance.Our patented LSR (Liquid Silicon Rubber) buffering layer and double APG (AutoPressure Gelation) process adopted in the producing of the embedded polethoroughly eliminates the cracking of the epoxy resin caused by the large differenceof thermal expansion coefficient between epoxy resin and ceramic in case of rapidchanging of the ambient temperature. APG process for LSR buffering layer ensuresthat there will not be any air gap or bubble between the buffering layer and ceramichousing, hence, the high electrical insulation strength of the embedded pole ofSecoVac series MV embedded pole vacuum circuit breaker is guaranteed.
The partial discharge value of embedded pole manufactured by our patented LSR(Liquid Silicon Rubber) buffering layer and double APG (Auto Pressure Gelation)process is below 5pc with an applied testing voltage of 1.2Um.

Modular Operation Mechanism
SecoVac series MV embedded pole vacuum circuit breaker is equipped with modularized, standardized and simplified operating mechanism, the mechanism consists of separated closing and opening modules, all the mechanical parts of the mechanism are integrated into these two modules . The closing and opening modules are universal to whole series of SecoVac embedded pole vacuum circuit breaker regardless of ratings, it means there is only one kind of closing and opening module for the whole SecoVac products family, thanks to such a design, the maintenance time and cost for the mechanism is low, the replacement of modules can be easily carried out on site. There is no impact on the original dynamic characteristic of the breaker after the replacement of modules, so the retest of the breaker is not required after the replacement of modules.
Another feature of the operating mechanism of SecoVac series MV embedded pole vacuum circuit breaker is that the total number of parts of the mechanism is reduced compared with the traditionally designed mechanism, so that the reliability of the mechanism is enhanced significantly.
The opening damper of the mechanism plays a very important role to ensure reliable performance and high mechanical endurance of SecoVac series MV embedded pole vacuum circuit breaker. By adoption of the opening damper, the overtravel and re-bounce of moving contacts of vacuum interrupters during the opening of this VCB is reduced to a minimum. The lower overtravel of the moving contacts means lower mechanical stress to the bellow of the vacuum interrupter, so the designed mechanical endurance of the vacuum interrupter is guaranteed. The lower re-bounce of the contact ensures low arc re-striking probability during the breaking of capacitive current, so the occurrence rate of operating overvoltage is reduced. By the contribution of the opening damper, SecoVac has successfully passed type tested as Class C2 breaker in accordance with IEC standards.

Front Panel
This front panel fits into a collar-frame in the equipment when the breaker is in the CONNECT position. It provides a metal barrier between the breaker compartment and the secondary device compartment. Well marked and easy-to-read operating controls and indicators include TRIP button, CLOSE button, OPEN/CLOSE indicator, CHARGE/DISCHRGE indicator, OPERATIONS counter and provision for manual charging the breaker.
Primary Disconnect
The primary disconnect finger set is rugged and easy to inspect. Designed for optimum contact, built of silver-plated copper and tested for continuous and short time current. Cycloid design is more convenient to connect and expand wider contact area than flat design. These disconnects provide proper contact integrity throughout the life of the gear for the critical primary disconnect function.
Breaker Mechanism
All the mechanical parts of the mechanism are integrated into opening and closing modules individually. The closing and opening modules are universal to whole series of SecoVac embedded pole vacuum circuit breaker in spite of the ratings. Such design assures no mechanical readjustment after the replacement, thereby not only shortens lead-time but also reduces operation and maintenance cost.
Interlock System
For personnel safety, SecoVac is designed with a number of mechanical and electrical interlocks. For example, breaker contacts must be open before the breaker can be moved to or from the CONNECT position. A positive mechanical stop is provided when the breaker reaches the CONNECT or TEST/DISCONNECT positions. Mechanical interference interlocks are provided to permit only the insertion of properly rated breakers into any specific compartment. These and other necessary interlocks provide a comprehensive protection system. Furthermore, springs automatically discharge when the breaker is withdrawn from the CONNECT position and breakers cannot be inserted in the closed position.
