Abstract
Aiming at two cases of abnormal noises signal appearing in the operation of GIS(Gas Insulated Switchgear)equipment,by various electric on-line test ways such as ultrasonic method, ultrahigh frequency method,and SF6 gas component analysis method,analyzes and compares GIS equipment appearing abnormal noise. The analysis result shows that due to the magnetic hysteresis of steel body in GIS equipment,the alternating magnetic field in a power frequency cycle change magnetic state of GIS which has the permeability,caused the abnormal noise. The electric on-line test shows that the noise will not bring harm to the operation of the GIS equipment.关键词
