Description

Technical Field

[0001] The utility model relates to the technical field of partial discharge monitoring, in particular to an online partial discharge monitoring device. Background Art

[0002] With the rapid improvement of social productivity, switchgear is more and more widely used in power systems. In the long-term operation of switchgear, due to the influence of factors such as vibration, temperature and humidity changes, the insulation strength will continue to decline, eventually causing failures and safety problems. Partial discharge is a typical phenomenon before the insulation defects of the switchgear are broken down. By monitoring the partial discharge phenomenon, the potential insulation faults inside the high-voltage switchgear can be detected in time, and the safe and reliable operation of the high-voltage switchgear can be promoted. At present, partial discharge is a pulse discharge, which will produce a series of physical phenomena and chemical changes such as light, sound, electrical and mechanical vibrations inside and around the power equipment. These various physical and chemical changes caused by partial discharge can provide detection signals for monitoring the insulation status inside the power equipment. When insulation defects appear inside the high-voltage electrical equipment, partial discharge signals will be generated. By detecting and analyzing the partial discharge signals, it can be determined whether there are insulation hazards inside the high-voltage electrical equipment to prevent the further expansion of potential accidents.
