6-35 kV供电系统单相接地故障研究

Research on Single-phase Grounding Fault of 6-35 kV Power Supply System

供电系统单相接地是配电系统最常见故障,多发生在潮湿、多雨天气。通过对6-35 kV配电线路发生单相接地故障原因的分析,指出单相接地故障对配电设备和配电网的危害,提出预防和故障处理办法,并建议应用新技术,减少单相接地故障的发生,确保配电网安全、经济和稳定运行。

Single-phase grounding of power supply system is the most common fault in power distribution system,which mostly occurs in wet and rainy weather.Based on analysis of the causes of single-phase ground fault in 6-35 kV distribution line,this paper points out the harm of single-phase ground fault to distribution equipment and distribution network,puts forward prevention and fault treatment methods,and recommends the application of new technology to reduce the occurrence of single-phase ground fault and ensure safe,economic and stable operation of distribution network.
