摘要： An electromagnet mechanism is coaxially disposed with a vacuum interrupter that is disposed in a circuit breaker, and has a movable core and a fixed core facing each other and an electromagnetic coil that makes the movable core and the fixed core separate or come into contact in response to electromagnetic force. A driving rod which is movably disposed in the axial direction of the electromagnet mechanism is coupled to the movable core, and in which one side is coupled to the circuit breaker and the other side passes through an opening side end plate of the electromagnet mechanism to be extended outward from the opening side end plate of the electromagnet mechanism. An indication unit is disposed on the opening side end plate of the electromagnet mechanism, and indicates a state of the circuit breaker in conjunction with the movement of the driving rod.

摘要： A power switchgear includes a circuit breaker including a container filled with an insulating gas, a stationary contact arranged in the container, and a movable contact that makes a movement to make contact with the stationary contact; an operation unit including a biasing member, and opens and closes the circuit breaker; and a linkage unit that transmits an biasing force of the biasing member to the circuit breaker. The linkage unit includes a rotary shaft, a lever including an engaging hole to be engaged with an outer periphery of the rotary shaft, and a pressing member that presses the rotary shaft onto an inner periphery of the engaging hole.

摘要： A power switching apparatus includes: a pressure tank having tube-like openings in a shank portion and having an insulating gas sealed therein; a vacuum valve housed in the pressure tank and connected to the pressure tank at one end; bushing conductors penetrating through the openings of the pressure tank and electrically connected to the vacuum valve; and current transformers provided on an outside of the pressure tank and measuring a current flowing through the bushing conductors. Tube-like current transformer installation portions on which to install the current transformers are provided above the openings of the pressure tank and an outside diameter of the openings of the pressure tank is made larger than an outside diameter of the current transformer installation portions.
