Disconnecting link operation mechanism box

Abstract

The invention provides a disconnecting link operation mechanism box. The disconnecting link operation mechanism box comprises a communication module, a control module, a disconnecting link driving apparatus, and a power supply module used for supplying power for the communication module and the control module, wherein the communication module is used for receiving an instruction, and uploading a signal corresponding to the received instruction to the control module; the control module is used for outputting one or more of a switch-on allowing signal, a switch-on action signal, a switch-off allowing signal and a switch-off action signal; and the respective signals are matched mutually or independently to control the disconnecting link driving apparatus, so as to enable the disconnecting link driving apparatus to control a disconnecting link mechanism to execute a switch-on action or a switch-off action. By virtue of the disconnecting link operation mechanism box, the problems of lowered reliability and low installation and operational and maintenance efficiency of the disconnecting link mechanism caused by the fact that signals are transmitted through a large number of cables due to separation of a secondary control loop and the operation mechanism box body of the existing conventional disconnecting link mechanism are solved.

Description

technical field [0001] The invention relates to the technical field of electrical devices, in particular to a knife switch operating mechanism box. Background technique [0002] The power industry is a basic industry and public utility that supports the development of the national economy and society. With the rapid development of my country's national economy and the continuous improvement of people's living standards, the degree of dependence on electricity is also increasing. In order to realize the reliability, safety, economy, high efficiency and many other benefits of the power grid, vigorously building a smart grid is the main development direction of the current and future power system. Isolating switches and grounding switches are widely used in substations, and their intelligence plays a role in promoting the intelligence of the entire power grid. [0003] Knife switch is a general term for switches that do not have switching load current and short-circuit current...

AI Technical Summary

Problems solved by technology

[0008] The invention provides a new type of intelligent knife switch operating mechanism box, the purpose of which is to solve the problem that the secondary control circuit of the conventional knife switch is separated from the body of the operating mechanism box, and the signal is transmitted through a large number of cables, which causes the reliability of the knife switch to be reduced, and the installation is difficult. The problem of low operation and maintenance efficiency
