Abstract

In order to study the seismic performance of 550 kV composite external insulation bushing for UHV substation in high altitude area, the shaking table test of seismic simulation was carried out on a real bushing and the numerical simulation analysis was carried out. By inputting white noise random wave and artificial wave, the dynamic characteristics of the specimen and the acceleration, strain and displacement responses of the key parts under the peak acceleration of 0.2g, 0.6g and 0.8g earthquakes are obtained. Through numerical simulation analysis, the mechanical response of the casing under wind load is verified. The results show that the first-order frequency of 550 kV composite external insulation bushing is 3.69 Hz ; under the action of the standard time history wave with the basic seismic acceleration of 0.8g, the strength of the casing composite component meets the seismic requirements, and the displacement response is obvious. The strength of the casing itself meets the mechanical requirements under wind load.
