Abstract
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...

Embodiment Construction
[0033] The idea of the present invention is to combine the electromagnet technology with the secondary pressure plate, overturn the working principle and structure of the traditional secondary pressure plate, realize the flexible control of the secondary pressure plate, improve the control efficiency of the secondary pressure plate and prevent misoperation.
[0034] The present invention generally includes the control of two loops, one loop is the coil loop of the electromagnet, the conduction and disconnection of the electromagnet are realized by controlling the loop, and the other is the secondary pressure plate circuit, which is the connection component of the secondary pressure plate itself and the loop formed by the external line. In fact, the present invention uses the opening and closing of the coil circuit to realize the opening and closing of the secondary platen circuit.
[0035] The present invention will be described in detail below in conjunction with the accomp...
