Product Description
ZW32 High Voltage Vacuum Circuit Breaker
ZW32 type outdoor pole mounted high voltage vacuum circuit breaker has rated 12kV voltage, three phase AC 50Hz outdoor high voltage switchgear, and is mainly used for opening and closing load current, overload current, short circuit current in electricity system. It plays protective and controlling function in power distribution system of substation, industrial and mining enterprises, rural area with frequent power grid operation, and especially used for transformation needs for city and rural networks. After adding controller, it can achieve automation function of distribution network.
Circuit breaker use three phase pillar structure, and have characters such as stable and reliable breaking performance, no danger of fire and explosion, maintenance free, small volume, light weight and long life time, ect. Circuit breaker use sealing structure, good sealing performance, and helpful for improving moisture-proof and condensation-proof performance, especially in cold and humid areas;
Using indoor epoxy resin which is around by silicone gel as solid insulated method has characters of high and low temperature resistance, ultraviolet resistance and aging resistance;
The operating mechanism adopts miniaturized spring operating mechanism, which has low power of energy storage motor, low energy consumption of opening and closing, direct transmission mode of mechanism transmission, fewer parts and high reliability;
Circuit breaker open and close operation can use manual operation, electric operation or remote control operation, and can cooperate with intelligent controller to realize distribution automation, and can also cooperate with recloser controller to make auto recloser or sectionalizer;
Circuit breaker can be equipped with three-phase linkage disconnector, and there are obvious breaks when disconnector is switched off, and it has mistake-proof interlocking device with circuit breaker body.
