Secondary pressure plate capable of remotely monitoring blocking/deblocking state

Abstract

The invention discloses a secondary pressure plate for electric equipment and operation method thereof. The secondary pressure plate comprises a pressure plate main body, a clutch mechanism and a fixed shaft; the clutch mechanism comprises a first base and a second base which are all installed on the top surface of the pressure plate main body, wherein an electromagnet is installed on the first baes, and a stretching tongue is installed on the second base; one end surface of an iron core of the electromagnet is opposite to one end surface of the stretching tongue, the on and off of the electromagnet can implement the connection and separation of the stretching tongue and the iron core; the fixed shaft is installed on the bottom surface of the pressure plate main body; a first binding post and a second binding post are installed on the end surface of the free end of the fixed shaft, the first binding post is electrically connected with the iron core, and the second binding post is electrically connected with the stretching tongue. Through the adoption of the method disclosed by the invention, the blocking / deblocking efficiency of the secondary pressure plate is improved, and the tedious degree of the entire installation of the secondary pressure plate is reduced.

Description

technical field [0001] The invention relates to a circuit breaker control device for electric equipment, in particular to a secondary pressure plate capable of remotely monitoring the state of switching on and off and an operation method thereof. Background technique [0002] The secondary pressure plate used in the traditional power system is a metal connection piece with holes at both ends. When the secondary pressure plate is put into operation and deactivated, it is necessary to unscrew the fastening nuts in sequence, and then remove the pressure plate connection piece. The operation is cumbersome and time-consuming. It is not conducive to shortening the switching operation time, especially when the whole set of protection device is disabled and needs to be removed, the operation is more cumbersome. In order to solve the above problems, in the Chinese patent literature, a utility model patent called snap-in lockable secondary pressing plate device is disclosed, the publi...
