A switch cabinet fault early warning system and its replacement method

Abstract

The object of the present invention is a switchgear failure early warning system and its replacement method, including a central processor and switchgear equipment, the switchgear equipment is provided with a plurality of switchgear equipment, and the switchgear equipment includes a switchgear static touch bar and a switchgear moving touch bar, The moving contact rod of the switch cabinet is embedded in the connecting groove of the static contact rod of the switch cabinet. A resistance meter is installed on each static contact rod of the switch cabinet and the moving contact rod of the switch cabinet. The resistance meter forms an early warning of equipment failure through the acquisition module and the central processor. The system collects the resistance value at the connection point of the switchgear equipment in real time, and monitors the fluctuation of the resistance value in real time, which can effectively alarm the equipment for failure, so as to realize the planned pre-update and maintenance treatment of the switchgear equipment in advance, and can Effectively prevent the phenomenon of emergency power failure in running equipment.

Description

technical field [0001] The invention relates to the field of power system safety, and mainly relates to a switch cabinet failure early warning system and a replacement method thereof. Background technique [0002] With the rapid development of our country's cities, and the rapid development of our country's power system, especially in the aspect of intelligent power, especially in the aspect of power components, especially in high-voltage circuit breakers, there is a gap between the moving contact and the static contact. A certain contact resistance, and because the environment of the power distribution cabinet of the power system will be relatively harsh, the air humidity is high, and the air temperature is high, resulting in aging or even damage to the components of the switchgear equipment, resulting in the switchgear equipment The operation is unstable, and even a large operation failure occurs. However, under the current situation, it is difficult to carry out early war...

[0002] With the rapid development of our country's cities, and the rapid development of our country's power system, especially in the aspect of intelligent power, especially in the aspect of power components, especially in high-voltage circuit breakers, there is a gap between the moving contact and the static contact. A certain contact resistance, and because the environment of the power distribution cabinet of the power system will be relatively harsh, the air humidity is high, and the air temperature is high, resulting in aging or even damage to the components of the switchgear equipment, resulting in the switchgear equipment The operation is unstable, and even a large operation failure occurs. However, under the current situation, it is difficult to carry out early warning and replacement and maintenance of the equipment in the cabinet. It is often replaced after a failure occurs, which largely causes power consumption. The situation of instability and emergency failures has largely caused potential safety hazards in power consumption
