Electromagnetic control device

摘要

Disclosed is an electromagnetic control device comprising: an electromagnet mechanism that performs opening/closing operation of a circuit breaker, having a movable core and a fixed core that are arranged facing each other and an electromagnetic coil that separates or brings into contact the movable core and the fixed core in response to electromagnetic force and that is arranged co-axially with a vacuum valve arranged within the circuit breaker; an electromagnetic control rod that is arranged in movable fashion in the axial direction of the electromagnet mechanism and that is linked with the movable core, and whereof one end is linked with the circuit breaker and the other end passes through an opening-side end plate of the electromagnet mechanism and extends to outside the opening-side end plate of the electromagnet mechanism; and a display section, arranged on the opening-side end plate of the electromagnet mechanism and that operates in a linked manner with the movement of the electromagnetic control rod and that displays the condition of the circuit breaker.
