Abstract

The invention relates to an online detection system of switchgear, comprising a CPU, a temperature sensing system, a mechanical and insulated signal input unit, a switching value input unit and a switching value output unit. The temperature sensing system is connected with a temperature detection signal input end for detecting the temperature information of a key point of power equipment; the mechanical and insulated signal input unit is connected with the CPU for detecting the state and the insulating condition of a high-voltage switch cabinet; and the switching value input unit and the switching value output unit are connected with a switching signal end of the CPU for monitoring the switchgear. The online detection system accurately measures the temperature of the key point of power equipment in real time and rapidly outputs a corresponding switching signal to execute corresponding action and confirm the safety of a power system.

Description

technical field [0001] The invention relates to an on-line detection system for switchgear. Background technique [0002] At present, in the power system, when the load current of medium and high voltage switchgear, GIS (gas insulated substation) and other high-voltage electrical appliances is too large, the power equipment will be damaged due to excessive temperature rise, which will affect the normal operation of the entire power system and even cause huge damage. economic loss. Therefore, it is of great significance to timely and accurately measure the temperature of key points of power equipment for finding and troubleshooting. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an online switchgear detection system that can timely and accurately measure the temperature of the key points of the power equipment and quickly output the corresponding switching signals to perform corresponding actions and ensure the ...
