摘　　要：随着电力电缆大幅增多,消弧线圈补偿已达最大档位,阻尼箱及控制部分技术落后,原设备性能已不能满足电网的要求。针对设备的运行现状,分析了存在的缺陷,提出了增容改造的方案,通过对系统对地电容电流计算确定了消弧线圈、接地变压器的容量,完成了新设备的选型与计算工作,系统实施后供电系统安全运行得到有力的保证,对提高配电网的运行可靠性起到了积极的作用。With significant increase of power cable, arc suppression coil compensation has reached its limit and, due to lag of damping cases and the control part in technology, the performance of original equipment can not meet requirements of power network. In view of operation status of the equipment, in this paper,the defects existed are analyzed and upgrading scheme is proposed. The capacity of arc suppression coil and of transformer is determined through calculation of capacitive current of system to earth and the type selection and calculation of new equipment is finished. Implementation of system assures safe operation of power system and plays an active role in improving reliable operation distribution power network.
