Research on high-voltage two-power intelligent switching device and control system

High-voltage two-power intelligent switching device and control system is consisted of a breaker with electric actuator, three-position switching device, intelligent controller and communication unit. The switching device and control system adopts Upper-line-in Lower-Line-out Method and Simple-Column Installation, which conform to the current circumstance of national grid transmission. In the meantime, its size is smaller than advanced similar products overseas. It is also featured by complete protection function, automatic report of operation circumstance, fault online diagnosis and four remote functions. It is also high in intelligent level and can be used as the keynote device in intelligent grid.
