Overview

Tavrida Electric’s OSM provides the following advantages:

Environmentally friendlyThe OSM is an air insulated outdoor circuit breaker with a patented combined insulation that makes it the environmentally friendly option - no oil or SF6 despite its compact size.The reliability of the design is proven by the worlds‘ most severe climate and pollution conditions test at the Koeberg Insulator Pollution Test Station (KIPTS) in South Africa.

Smallest Dimensions and lowest WeightTavrida Electric‘s innovative vacuum circuit breaker and the robust aluminium tank contribute to the light weight of the OSM - not more than 76kg - making it the most light weight outdoor circuit breaker in its class, greatly simplifying shipping, handling and installation.

Highest Availability30,000 C-O operations at rated current and up to 100 operations with full short circuit breaking current without any maintenance.

Optimized MeasurementBuilt-in voltage sensors on all six poles and three current transformers guarantee high accuracy over a wide measurement range.

Vacuum Circuit Breaker - VCBEach OSM is equipped with Tavrida Electric’s innovative vacuum circuit breaker (VCB). Tavrida Electric has simplified the mechanical structure of the vacuum circuit breaker to the greatest possible degree. It uses three single-coil magnetic actuators, one per pole. All switching elements are assembled along a single axis - all mechanical movements are therefore direct and linear. The three actuators are mounted in a steel frame and mechanically linked by a synchronizing shaft. Optimal selection of all components makes these the most compact vacuum circuit breakers in the world.

Failure of critical components, such as· mechanical latches· gears, chains, bearings and levers· tripping and closing coils· spring charging motors...are completely avoided.

Maximizing the benefits of the drive mechanism requires vacuum interrupters that combine small dimensions with an extraordinarily long mechanical and electrical lifespan. The use of a predefined axial magnetic field shape provides even distribution of current density and consequently substantial improvement of vacuum interrupting performance.Carefully selected contact material and expert contact design as well as optimized movement and switching speed result in bounce-free closing.

Substantial increase in mechanical lifespan as well as size reduction of Tavrida Electric vacuum interrupters was achieved by utilizing metal bellows consisting of welded single discs as opposed to the conventional use of folded steel.

The result is 30,000 C-O cycles at rated current or up to 100 operations at full short-circuit breaking current without the need to replace or adjust any parts of the vacuum circuit breaker.

Tavrida Electric´s vacuum circuit breaker are entirely maintenance free over a total life expectancy of at least 30 years.

Closing Closing operation is possible only if the manual trip hook is in the upper position. In the open position the contacts are kept open by the force of the opening springs. To close the contacts the coils of the magnetic actuators are excited by a current impulse of the close capacitors of the CM. As a result the contacts close, while at the same time the opening springs are compressed. In the closed position the contacts are kept closed by means of the magnetic force only. The VCB maintains the closed position without mechanical latching also in case of a failure of the auxiliary power supply (Figure 4).

Opening To open the contacts a current impulse in the reverse polarity derived from the opening capacitors of the CM is injected in the coils of the magnetic actuators releasing the magnetic holding force. The compressed opening springs and contact pressure springs open the contacts (Figure 4).

Manual Closing The VCB can only be closed electrically via the CM. In the case of a failure of auxiliary power supply the contacts can be closed using an alternative auxiliary power supply such as a battery. Mechanical closing is not possible and leads to the destruction of the VCB.

Manual Trip When the manual trip hook is pulled down the synchronizing shaft is rotated. A force exceeding the magnetic attraction forces of the ring magnet is applied to the armature, which subsequently starts to move. As the air gap increases, the opening springs and the contact pressure springs overcome the magnetic holding force, and the vacuum interrupter opens.

Each OSM has the following rating plates:· Serial number plate · Rating plate

The tank supports provide a firm, stable support. The supports are protection against chipping of the powder coating during transportation. These supports shall be removed after installation on the pole.

The protective tank is equipped with a ceramic breather on the bottom. The breather ensures that no dust or pollution ingress occurs.

Protective Tank

The OSM are constructed from an aluminium tank incorporating the vacuum circuit breaker with single coil magnetic actuators. The protective tank consists of two main parts: The housing and the bottom protective cover riveted to the housing. The OSM housing and the cover are made of a corrosion resistant aluminium alloy. Water-tight aluminium rivets are used to secure the cover. The tank is powder coated in light grey (RAL 7038). The tank including the control cable cover provides IP65 degree of protection.

Four threaded holes (M12x30) on each side of the tank allow mounting equipment for pole or substation installation to be fitted. Two of these threaded holes are used to install the set of lifting lugs on the tank. The earthing provision (M12x30 threaded hole) is labelled for easy identification.
