Abstract: The present disclosure provides a gas-insulated vacuum load break switch, including a high-voltage conductive loop having three phases independent from each other and of the same design, a control operating mechanism, a support box and a transmission apparatus. Each phase of the high-voltage conductive loop includes a load break switch unit with a vacuum interrupter, an isolating switch unit with an isolator, a plastic housing supporting the load break switch unit and the isolating switch unit, and an earthing switch unit; the control operating mechanism includes an operating mechanism for controlling the load break switch unit, an operating rod for controlling the isolating switch unit, and an operating mechanism for controlling the earthing switch unit.
