摘要
1简介为了配合GB/T 3667.1＂交流电动机电容器第1部分：总则—性能、试验和额定值—安全要求—安装和运行导则＂、GB/T 3667.2＂交流电动机电容器第2部分：电动机起动电容器＂、GB/T 12747.1＂标称电压1 kV及以下交流电力系统用自愈式并联电容器第1部分：
The spark gap, as an important equipment for capacitor over-vohage protection in extra- high voltage series compensation system, is equipped with a special trigging device for its reliable operation. The incorrect trigging of the spark always occurs at early operation stage of the series compensation system. In this paper, the factors possibly influencing maloperation of the spark gap are analyzed based on actual engineering data and the main cause to result in maloperation is the stray capacitance. The possible solution is proposed for the stray capacitance and this problem is solved by simply adding a shielding ring considering the actual project cases.
