A high-voltage switchgear and an operating mechanism thereof

The invention provides a high-voltage switchgear and an operating mechanism thereof. A high voltage switchgear according to the present invention, comprises a high-voltage switch and an operating mechanism for driving the high-voltage switch to switch on and off, The operating mechanism comprises a fixing frame, a linear actuator is installed on the fixing frame, a driving crank arm for driving the switch driving spindle to rotate synchronously with the driving crank arm is rotatably installed on the fixing frame, and the output end of the linear actuator is connected with the driving crank arm and drives the driving crank arm to rotate when the output linear reciprocating motion of the driving crank arm. The high-voltage switch device of the invention adopts the linear actuator as the power source of the operating mechanism, simplifies the transmission structure of the mechanism, reduces the number of parts, makes the whole driving device modular, reduces the difficulty of productionassembly and field instal
