［摘要］通过数值分析手段，建立了特高压高压并联电抗器回路数值模型，运用反应谱分析方法，针对特高压回路系统各参数对设备抗震性能的影响进行综合研究，分析了支架刚度、设备间距及设备间连接管母壁厚等参数对回路中设备抗震性能的影响，寻求有利于提高特高压电气设备抗震性能的回路系统各参数的最佳范围。提出了频率不低于7Hz的电气设备支架设计原则。研究结果还表明，设备间距变化主要影响设备位移和金具与端子竖向受力，在满足电气设备工艺要求的前提下，回路中设备间距在5～9m时有利于提高设备的抗震性能。连接管母壁厚由10mm变为8mm后，对回路中设备的应力影响小于4%，影响程度相对较小，说明此两种型号的管母对设备地震响应的改变不起控制作用，宜根据实际工程需要选择合适的管母型号。

Abstract:A numerical model of UHV high voltage shunt reactor loop was established and a comprehensive research on the influences of equipment seismic performances caused by various parameters in loop system was made by using response spectrum analysis method. Then the relationship between the seismic performance of equipment in loop and the parameters which contain the frame stiffness, span between equipment and the thickness of connecting tube bus etc. were analyzed. The best range of the parameters of the loop system which is helpful to improve the seismic performance of UHV electrical equipment was found. The design principle was proposed that the frequency of electrical equipment support is not less than 7Hz. The results show that the change of equipment spacing mainly affects the displacement of equipment and the vertical force of fittings and terminals. It is helpful to improve the seismic performance of the equipment that the equipment spacing is 5～9m under the condition of meeting the requirements of electrical function. When the thickness of connecting tube bus is changed from 10mm to 8mm, the effect of equipment stress in the loop is less than 4%. The degree of the influence is small, which shows that the two types of tube bus have no control of the seismic response of the equipment. Therefore, the appropriate type of tube bus should be selected according to the actual engineering requirements.

Keywords:UHV; electrical equipment; seismic performance; high voltage shunt reactor loop
