Abstract

The switchgear is one of the important electrical equipment in the power system. In the actual operation process, various types of discharges may occur in the switchgear, which poses a serious threat to the stable operation of the power system and the safe operation of electrical equipment. Therefore, the status monitoring and diagnostic technology of switchgear has become a necessary means for the safe and stable operation of the power system. This article studies the time-frequency characteristics analysis and application research of typical discharge signals in switchgear. By comparing and analyzing different signal sensing technologies, suitable detection frequency bands and signal sensing methods have been determined, achieving more accurate switchgear status detection and diagnosis.
