ZW8-12 series outdoor high voltage vacuum circuit breaker


ZW8-12 series outdoor high voltage vacuum circuit breaker

ZW8-12 type outdoor high voltage vacuum circuit breakers, commonly known as Zhu on the switch , the Department of rated voltage 12KV, three-phase AC

50Hz outdoor high-voltage power distribution equipment. The circuit breaker complex sets of insulated , side-mounted parade motivation enough , easy to maintain , does not apply to an altitude higher than 2000m, excluding the oil spills, leaks and other problems, is one of the best products for outdoor power distribution system.

With over- current protection , anti- surge controller can achieve inrush current delay and instantaneous overcurrent , short quick break trip function ; station , opening and storage can be manual or electric operation and remote operation ; controller can be equipped with FTU achieve distribution automation, controllers can also be equipped with heavy weight sets consisting tuner .

Product Features :

Three-phase circuit breaker box structure , the unique design of rain , outdoor sealing problems breaker .

Ceramic vacuum interrupter chamber interrupter interrupter using goblet longitudinal magnetic field , strong arcing ability contacts using a special material , effectively inhibited the operation overvoltage.

Other insulated with silicone rubber , silicone rubber hydrophobicity good, strong anti-aging properties , with anti- condensation , strong anti-contamination performance, etc., while increasing the creepage distance between the outer surface , effectively ensuring the

Absolutely sash performance.

Cabinets composite insulation ( dry insulation ) . Between poles and pole insulated cover for the use of SMC insulation ; station at the junction box is sealed with a seal at the bottom of the well casing is equipped with moisture

Agent , to ensure the drying air cabinets .

Three-phase linkage, in the state of isolation switches gate obvious visible fracture between isolation switch and circuit breaker interlock to prevent misuse and prevent units with load isolation switch , circuit breaker in the station gates

Isolating switch can not be operated when the state before the operation when the circuit-breaker status disconnectors , circuit breakers and beneficial overhaul .

Circuit breaker can be equipped with five single-coil current transformers , protection , measurement and metering signals , variable ratio 50-630/5i optional .

Breaker box with spray treatment and stainless steel surface polishing 2 ways , beautiful exterior colors, good corrosion resistance.

Operating mechanism with spring operating mechanism , with manual operation, the operation of two electric , and with overcurrent tripping device . Can complete a weight bench brake operation.

Products fully meet GB1984-2003, GB/T11022-1999, DL/T403, DL/T402 other domestic standards.

Xi'an high-voltage circuit breakers in the electrical testing center through all types of tests , includingtemperature rise test , insulation test , short-circuit breaking and off table test , short-term and peak withstand current test

Inspection , mechanical life, no load cable Founding test, partial discharge test , low temperature test .
