摘要：Due to the influence of electromagnetic force, the running GIS gas (insulated switchgear) will produce a certain vibration frequency. The other factors, such as resonance, disturbance of internal gas, bring abnormal vibration to the GIS shell. Because of the bad effects followed, the components of GIS can be damaged to the leakage which will lead to power failure in serious cases. In this paper, the vibration analysis of a 1000kV UHV substation 500kV area GIS is carried out. The vibration frequency of the GIS equipment was obtained by field vibration detection, and through the finite element modal analysis, we got the natural frequency and modal shape. It was found that the vibration frequency of the GIS shell is normal reportedly, and the possibility of resonance is ruled out.
