Description

technical field [0001] The invention relates to a partial discharge detection device and a detection method, in particular to a detection device and method for the number of ultraviolet partial discharge photons based on laser radar ranging compensation. Background technique [0002] Since partial discharge is the main cause of insulation aging of power equipment, the detection of partial discharge in the power system has become the main component of online intelligent detection. The safe operation of equipment and the accelerated aging of equipment insulation, so it is very important to quickly and effectively detect partial discharge. [0003] Solar-blind ultraviolet imaging is a detection method for surface discharge of equipment, because of its advantages of long detection distance, non-contact, and accurate positioning, it has been widely used in the detection of partial discharge in power systems. Among them, the number of photons is the key parameter to quantify the ...

Problems solved by technology

In actual engineering, the instrument gain and current pulse can be controlled at the required value, but the detection distance will vary due to the location of the corona discharge, resulting in no comparable detection results, and it is difficult to determine a specific value in the ultraviolet imaging detection Photon threshold
