General

ZW32-12/M series high-voltage pole-mounted permanent-magnetic vacuum circuit breaker for outdoor is an outdoor power distribution equipment suitable for systems of AC50Hz and rated voltage of 12kV.It is mainly used for making and breaking the load current,overload current and short-circuit current in power systems,application for protection and control of distribution systems in transformer substation and industrial and mining enterprises,especially suitable for rural power grids and other frequently operated locations.
This circuit breaker is in accordance with GB1984-2003 High-voltage Alternating-current Circuit Breaker.JB3855-2008 Indoor High-voltage Alternating-current Vacuum Circuit breaker of 3.6-40.5kV and DL403-91 Specification for Indoor High-voltage Alternating-current Circuit Breaker of 10-35kV,also is in conformity with relevant requirements of IEC56.

Structure and features

Full-enclosed structure has favorable sealing performance,helps to improve moisture proof and anti condensation performance,is applicable for high-temperature humid areas,effectively protect the switch from mechanical rust in outdoor for long time.
Vacuum arc-extinguishing chamber has stable and reliable breaking performance,little contact wear,free of flammable or explosive danger,free of maintenance,safe and reliable.
Special alicyclic epoxy resin strenghthens insulating stability in humid condition,protects against erosion caused by ultraviolet radiation,is suitable for environment where has high weatherproof requirements and severe running conditions.
The circuit breaker adopts permanent-magnetic operating mechanism,has advantages of less parts,maintenance free,more than30,000 times of mechanical life,high reliability.

Features

Small volume,light weight,maintenance free,long service life;
It can be equipped with disconnection switch,with obvious breaking point;
It can be equipped with controller to realize automatic reclosing,reclosing times and reclosing time can be selected randomly,with quick-break protection,and the fixed value can be set randomly;
Under-pole remote control,many operating modes such as electric and manual;
It is able to real-time monitor the running current of circuitries
