摘　　要：近年来,配网变电站的容量越来越大,而在工业用电和居民生活用电负荷主要以偏感性负荷为主,为了提高有功能量的输送和经济效益,在变电站内就要使用更多的并联补偿电容器,在电容器组中还配有放电线圈、避雷器、不平衡电流互感器以及大量支撑绝缘子,所以电容器组设备的耐压试验是一项复杂的工作。本文通过对大量电容器组现场交流耐压试验总结出了一套非常实用的经验公式,对现场试验接线、操作流程也进行了详细、合理的讲解,实现了更方便、更全面、更有效的对电容器组设备进行并联补偿耐压试验。In recent years, the capacity of distribution substation is growing and electric load is main- ly inductive in the industrial and residential electricity consumption. For improving transmission of active power and economic efficiency, more and more shunt compensation capacitors are used at sub- station. The discharge coil, surge arrester, the imbalance current transformer and the number of the support insulators are provided in the capacitor bank and, therefore, withstand voltage test of the ca- pacitor bank is a complicated task. In this paper, a set of very practical empirical formula is summa- rized throughout field AC withstand voltage test of the number of capacitor banks. The wiring and op- eration process of field test are also explained in detail so to achieve more convenient, more compre- hensive and more effective shunt compensation withstand voltage test on capacitor banks.
