摘要
本文介绍了漳村煤矿110 kV变电站运用主变有载调压开关运满足煤矿井下供电系统电压稳定的运行情况,同时针对变压器有载调压分接开关内部放电故障,通过对变压器油样试验、局部放电试验和故障定位诊断系统准确查找到了变压器有载调压分接开关内放电位置,分析了有载调压分接开关发生内部放电的原因并提出了维护建议。
The operation of using the on-load tap-changer of the main transformer of the 110kV substation in the Zhangcun Coal Mine to meet the voltage stability of underground power supply system is described. At the same time, for the internal discharge fault of the on-load tap-changer of the transformer,the discharge position of the on-load tap-changer of the transformer was accurately found through the oil sample test of the transformer,the partial discharge test and fault location diagnosis system, the causes of internal discharge of the on-load tap-changer were analyzed, and the maintenance recommendations were proposed.
