ZW20D-12F outdoor high voltage primary and secondary fusion complete set of column circuit breaker (hereinafter referred to as demarcation circuit breaker) is a new product independently developed by our company. It is a multi-functional intelligent device product integrating the four switches of the segment controller. ) consists of three major parts, the products are widely used in 10kV, 13kV urban and rural distribution network overhead ring network lines as segment isolation switches and tie switches, automatic switchgear that can implement ring network line load allocation, in the power supply of large users. The branch line can be used as a demarcation switch (commonly known as watchdog), and the feeder overhead distribution network is used as a recloser and a sectionalizer. The demarcation circuit breaker has a remote management mode, protection control function and communication function. It can reliably judge and detect mA zero-sequence current and phase-to-phase short-circuit fault current in the industry, and realize automatic removal of single-phase ground fault and phase-to-phase short-circuit fault.
