Auto Recloser Circuit Breaker ZW32-12F/T630-25 12kv Remote Control /High Voltage AC Vacuum Circuit Breaker Auto Recloser
ZW32-12F watchdog dog intelligent outdoor vacuum circuit breaker(hereinafter referred to as demarcation circuit breaker) is a new product developed by our company independently. The demarcation circuit breaker is a multi-functional intelligent device product integrating vacuum circuit breaker, demarcation circuit breaker and segmental device.Boundary between main configuration by vacuum circuit breaker ontology, intelligent controller, the external boundary type voltage transformer (note: in the distribution network automation ring line optional PT) on both sides of three parts, the products are widely used in 10 kv city of ring network, rural power distribution network overhead line segment isolating switch, contact switch, can be a ring line load allocation automatic switching device, in the big user power supply branch circuit can be used as a dividing line switch (commonly known as watchdog), feeder overhead distribution network and used
as the boundary between the breaker section, boundary between vacuum circuit breaker with remote management mode, protection control function and communication function.It can reliably judge and detect the zero-sequence current and interphase short-circuit fault current in the boundary, and realize the automatic removal of single-phase grounding fault and interphase short-circuit fault.
