Vacuum separated switch for AC high voltage load

The utility model relates to a vacuum separated switch for the AC high voltage load, belonging to the technical field of the high voltage electrical apparatus. The utility model adopts the modularized assembly. The three phases of A, B, C respectively comprise the same module. Every single-phase module presents the horn type structure. A cast vacuum arc chute and an arc chute device are installed on the upper part of every single-phase module. The three single-phase modules are connected together via a connecting pipe and are installed on the frame. An electric mechanism and a hand-operating mechanism are connected with the three single-phase modules via a drive link. The position of the contact head of the separated knife is designed with an electroconductive grease case whose inside is filled with electroconductive grease to protect the conductive contact. The static contact adopts the wobbler contact to improve conductivity. The arc chute device adopts the bistable structure at the combination and separation positions, having less components, and the operation of the mechanism is reliable. The electric mechanism and the hand-operating mechanism are designed with a clutch which decreases the resistance of the hand-operating combination and separation. The utility model is adapted for the AC 50Hz electrical distribution system whose nominal voltage is 40.5kV or is less than 40.5kV.
