摘要
广州雷电地闪分布密集,为电网设备雷害高发区域, 2014年以来出现的10 kV架空馈线跳闸次数较多。本文针对广州某区历次跳闸情况,从外部环境、绝缘配置、防雷措施、网架设计等方面分析了跳闸原因,提出了适用于不同环境和运行条件的10kV架空馈线重复跳闸防治措施,希望有助于降低10 k V架空馈线重复跳闸率,提高增城区配网线路的可靠性。
Guangzhou is a high-risk area for power grid equipment due to densely distributed lightning flash,and a number of 10 kV overhead feeder trips have occurred since 2014.According to the previous trips in a certain district of Guangzhou,this paper analyzed the trip causes from the aspects of external environment,insulation configuration,lightning protection measures and grid design,proposed the prevention and control measures for repeated tripping of 10 kV overhead feeders in different environments and operating conditions,which is hoping to help reduce the repeat trip rate of 10 kV overhead feeders and improve the reliability of distribution lines in Zengcheng District.
