Gd-smart Intelligent boundary breaker

GDsmart - 12 f1 boundary between outdoor ac high voltage vacuum circuit breaker (hereinafter referred to as the dividing line circuit breaker) is my company independent research and development of a new product, the dividing line circuit breaker is a concentration of vacuum circuit breaker, the vacuum load switch, the reclosing and section four open about the integration of multi-functional intelligent device products, main configuration by the boundary between vacuum circuit breaker ontology, PSC100 controller, the external voltage transformer (note: Optional in the distribution network automation ring line of bilateral PT) products are widely used in the ring network and the urban, rural power distribution network overhead line section isolation switch and contact switch, can be a ring line load allocation automatic switching device, in the big user power supply branch circuit can be used as separating switch (commonly known as watchdog), feeder overhead distribution network for the reclosing and 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 phase-to-phase short-circuit fault current within the boundary of milliamps, and realize the automatic removal of single-phase ground fault and phase-to-phase short-circuit fault.

The body switch is vacuum arcing extinguishing, and SF6, N2 mixed gas insulation is adopted. The box body adopts gas sealing, explosion-proof, insulation structure technology introduced from Japan, Germany and France, and the overall sealing performance is excellent. The mixed gas SF6 and N2 filled in the interior does not leak and is not affected by the external environment. The spring operating mechanism has been miniaturized and optimized, and the operation reliability is much higher than the traditional spring mechanism in China.
