Movable emergency opening device for 10kV switch cabinet

By designing a mobile emergency tripping device for 10kV switchgear, the device utilizes a remote control coil to drive the iron core movement, thereby enabling remote tripping of the circuit breaker. This solves the safety hazard problem when the circuit breaker cannot be tripped electrically, and reduces the risk of personal injury.

Abstract

The utility model provides a movable emergency opening device for a 10kV switch cabinet, which relates to the technical field of switch cabinets and comprises a fixed mounting mechanism, a mounting extension mechanism and a coil with an iron core. The fixed installation mechanism is used for being fixedly installed in the 10kV switch cabinet, one end of the installation extension mechanism is fixedly installed on the fixed installation mechanism, and the other end of the installation extension mechanism is provided with a coil with an iron core and faces a circuit breaker control panel in the switch cabinet; the outer side end of the iron core is used for being in contact with a circuit breaker manual opening button on a circuit breaker control panel; and the coil with the iron core is connected with a power supply outside the 10kV switch cabinet and is used for driving the iron core to move through power supply on-off of the coil with the iron core so as to realize remote opening of the manual opening button of the circuit breaker. According to the scheme, the circuit breaker can be disconnected by remotely operating the manual opening button, so that potential safety hazards of operators are reduced, and the situation that the power failure range is expanded due to the fact that the circuit breaker cannot be automatically opened is avoided.
