摘　　要：并联电容器投入电网时会产生的较大的涌流,有可能对电容器内部的部件,特别是内熔丝造成损伤,因此必须对电容器耐受涌流能力进行考核。通过对涌流产生原因的理论分析,确定了在试验室条件下用放电电流模拟涌流的方案,对电容器的耐涌流能力进行了试验。Switching Shunt capacitor bank would generate a large transient inrush current in power system. Such kind of current could damage the components in capacitors, especially the internal fuses. For this reason, inrush current withstand capability of capacitors should be checked. In this paper, the generation cause of inrush current is analyzed theoretically, and meanwhile, the scheme of discharge current to simulate current is determined in the lab.
