Switch cabinet fault early warning system and replacement method thereof

Abstract

The invention provides a switch cabinet fault early warning system and a replacement method thereof. The switch cabinet fault early warning system comprises a central processing unit and switch cabinet devices; a plurality of switch cabinet devices are provided; each switch cabinet device comprises a switch cabinet fixed contact rod and a switch cabinet movable contact rod; the switch cabinet movable contact rod is embedded into the connecting groove of the switch cabinet fixed contact rod; each switch cabinet fixed contact rod and switch cabinet movable contact rod are respectively provided with resistance meters; and the resistance meters and the central processing unit form a device fault early warning system through an acquisition module. The resistance values of the connection positions of the switch cabinet devices are acquired in real time; the fluctuation conditions of the resistance values are monitored in real time; fault warning can be performed for the devices effectively;and therefore, the switch cabinet devices can be updated and maintained in advance in a planned manner, and the emergency power utilization faults of an operating device can be effectively prevented.

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
