【摘要】：干式电抗器是变电站中的复杂电气设备,与其他设备相比这种设备在地震作用下的动力响应更为复杂。对由复合材料构成支撑结构的110k V干式电抗器进行抗震性能振动台试验研究,通过白噪声扫频和抗震试验,测定设备频率、阻尼以及关键部位的位移、应变和加速度响应,研究电抗器设备在地震作用下的地震响应规律。试验结果表明:复合材料电抗器设备在试验前后,频率、阻尼等动力特性变化较大;在不同强度地震波作用下设备的地震响应基本呈线性变化,结构基本呈线性特性;设备最大应变发生在设备支架根部,设备支架根部为最危险截面;复合材料由于刚度较弱,地震位移响应较大,在判定设备抗震性能时应考虑位移响应对设备电气功能的影响。
[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.
