110kV復(fù)合材料干式電抗器抗震性能振動(dòng)臺(tái)試驗(yàn)研究
[Abstract]:Dry reactor is a complex electrical equipment in substation. Compared with other equipments, the dynamic response of dry reactor is more complicated under earthquake. The seismic performance of 110kV dry reactor supported by composite material is studied by shaking table test. The frequency, damping and displacement, strain and acceleration responses of the equipment are measured by white noise sweep and seismic test. The seismic response of reactor equipment under earthquake is studied. The experimental results show that the dynamic characteristics of the composite reactor equipment such as frequency and damping change greatly before and after the test, and the seismic response of the equipment under the action of seismic waves of different intensity is basically linear, and the structure is basically linear. The maximum strain of the equipment occurs at the root of the equipment support, and the root of the equipment support is the most dangerous cross section; because of the weak stiffness and the large seismic displacement response of the composite material, the influence of the displacement response on the electrical function of the equipment should be considered when judging the seismic performance of the equipment.
