摘要：The mechanical fault of GIS equipment is the main cause of abnormal vibration of GIS equipment. Therefore, it is necessary to detect and diagnose the mechanical fault of GIS equipment. The vibration amplitude of GIS equipment under normal circumstances is mainly concentrated at 100 Hz. When the vibration is abnormal, a large amplitude will appear at other frequencies. In this paper, the vibration detection experiment is carried out for the vibration of the 110kV GIS equipment under normal and abnormal conditions, and the vibration signal is analyzed and processed by wavelet analysis and spectrum analysis. The obtained results are consistent with the on-site detection, thus verifying the applicability of the signal processing method in judging faults such as abnormal vibration of GIS equipment.
