Description

ZW20-12 boundary between outdoor ac high-voltage vacuum switch (hereinafter referred to as the dividing line switch) is a new product developed by our company, dividing line switch is set vacuum circuit breaker, the vacuum load switch, the rec losing and section four open about the integration of multi-functional intelligent products, the main configuration ontology by vacuum switch, intelligent controller, the external electric transformer (note: in the distribution network automation ring line optional PT) on both sides of three parts. Products are widely used in IO to 24 kv city ring network, rural power distribution network overhead line section switch and switch, may apply in the ring network line load allocation automatic switching device, in the big user power supply branch circuit can be used as a dividing line switches (commonly known as watchdog), feeder overhead distribution network for the reclosing and section, dividing line switch with remote management modes, protection control function and communication function. It can reliably judge and detect milliampere-level zero sequence current and interphase short circuit fault current, and realize automatic removal of single-phase grounding fault and interphase short circuit fault.
