vacuum circuit breaker
ZWV32 outdoor high-voltage vacuum circuit breaker is an outdoor distribution equipment with a rated voltage of 12KV, 15kV phase AC 50HZ~60Hz. It is suitable for protecting electrical units and terminal equipment in substations and industrial and mining enterprise distribution systems, and plays a role in the distribution, control, and protection of electrical equipment. When used for isolation and control purposes, as well as in places where rural power grids are frequently operated, circuit breakers can also be used as ring network supply and switch combinations, or as section switches. They are mainly used to open and close load currents, overload currents, and short-circuit currents in power systems. The vacuum arc extinguishing chamber adopts patented sealing technology, and the external insulation adopts silicone rubber sleeve, which has long service life, high reliability, good weather resistance, easy transportation to Chongqing, and high cost-effectiveness; The operating mechanism adopts a miniaturized and highly reliable spring operating mechanism, with a simple structure and a mechanical life of up to 20000 times;If advanced permanent magnet mechanisms are used, the mechanical performance will be more stable and reliable, and manual opening and closing mechanisms can be installed. If necessary, on-site opening and closing operations can be carried out. This circuit breaker can be paired with a controller to form a recloser, achieving the "four remote" functions of remote control, telemetry, remote signaling, and remote adjustment. It is safe, reliable, easy to operate, and easy to maintain and install. Product features: No combustion and explosion hazards, maintenance free, small size, light weight (less than 100kg), long service life (10000 times), safe and reliable, simple operation, easy maintenance and installation.
