Zw32 12kv 3-Pole Automatic Recloser High Voltage Outdoor Vacuum Circuit Breaker
ZW32-12 series outdoor high voltage vacuum circuit breakers are outdoor power distribution equipment with rated voltage 12kV and three-phase AC 50Hz.It is mainly used to open and close the load current, overload current and short circuit current in the power system. It is suitable for protection and control in urban and rural power grids, and more suitable forfrequent operation places.
Circuit breaker supporting intelligent controller, not only provides a stable working power supply for the operating mechanism,but also provides a reliable protection function and control means forthe circuit breaker, intelligent controller has a complete closing inrush current, overcurrent, short circuit and other protection functions, the protection parameters are continuously adjustable; Intelligent controller also has local operation and local remote control operation function, while the use of intelligent controller RS232 communication interface, through the selection of different means of communication, circuit breaker can also achieve wired/wireless/optical fiber and other remote control, to achieve power system “four remote” operation.
Features
(1) Equiped with vacuum arc extinguishing system, of stable and reliable breaking performance,with advantages of no fire and explosion hazard, safety, maintenance-free, small size, light weight and long service life.
(2) Fully enclosed structure with good sealing performance, suitable for use in areas of high temperature humidity.
(3) Can be installed with 50/5 ~ 600/5 current transformer according to user’s requirements.
(4) The closing and opening of the circuit breaker can be operated manually or electrically, and can be controlled remotely.
(5) The operating mechanism sealed inside the switch box, can effectively avoid the corrosion of the switch mechanism caused by the long-term outdoor environment.
(6) The operating mechanism is novel, simple, reliable in action, small in size, and has a mechanical life of more than 10,000 times.
(7) Can be installed with outdoor disconnector to form a reliable mechanical interlocking device with the circuit breaker.
