摘要
经分析发现导致配电网单相接地故障事故扩大的原因是过大电容电流及接地电流中的有功分量和高次谐波使接地点残流难以控制在规定范围内造成的。解决问题的可靠途径是将故障设备立即从运行电网中切除。
This paper analyzes and finds the causes of thefaults in distribution power networks. Capacitive overcur-rent, active component and high order harmonics in neutralcurrent are the main reasons of the faults. The reliable ap-proach to solve this kind of problems is removal of the fault-ed equipment from the power systems as soon as possible.
