ZW32-12 outdoor high-voltage vacuum circuit breaker is an outdoor power distribution equipment with a rated voltage of 12kV and three-phase AC 50Hz. It is suitable for protection and control in power distribution systems of substations and industrial and mining enterprises, as well as places where rural power grids are frequently operated. It can also be used as power distribution, control of ring network power supply units and terminal equipment, and protection of electrical equipment. When the circuit breaker is combined with the disconnector, it can also be used as a section switch. It is mainly used to break and close the load current, overload current and short-circuit current in the power system. The vacuum interrupter adopts patented sealing technology, and the external insulation adopts silicone rubber bushing, which has long service life, high reliability, good weather resistance, convenient transportation and high cost performance. The operating mechanism is a miniaturized, highly reliable spring operating mechanism with simple structure and a mechanical life of 20000 times. If the advanced permanent magnet mechanism is adopted, the mechanical performance will be more stable and reliable; It can also be equipped with a manual opening and closing mechanism, which can be manually opened and closed on site when necessary.
The circuit breaker can be matched with the controller to form a recloser, realizing the "four remote" functions of remote control, telemetering, remote signaling and remote adjustment.
Product features: no combustion and explosion hazard, maintenance free, small size, light weight (less than 100kg), long service life (10000 times), safe and reliable, simple operation, convenient maintenance and installation
