摘要： Embodiments of the present disclosure relate to a switch device, comprising: a first three-position switch; a second three-position switch disposed below the first three-position switch; a circuit breaker disposed between the first three-position switch and the second three-position switch. A first interlock unit is disposed above the circuit breaker and connected to the circuit breaker and the first three-position switch, and configured to block a manual operation of the first three-position switch in a closed state of the circuit breaker, and configured to block a manual closing operation of the circuit breaker while the first three-position switch is manually operated in an open state of the circuit breaker. A second interlock unit is disposed below the circuit breaker and connected to the circuit breaker and the second three-position switch, and is configured to block a manual operation of the second three-position switch in the closed state of the circuit breaker, and configured to block a manual closing operation of the circuit breaker while the second three-position switch is manually operated in the open state of the circuit breaker.

摘要： 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.
