摘要
10 kV配电网架空绝缘导线经常发生雷击断线事故,严重影响配电线路的供电可靠性。笔者结合海南地区某10 kV配电线路的具体实际情况,通过现场调研及大量的理论分析计算,对架空绝缘导线雷击断线事故的原因和机理进行了深入剖析,并提出了提高线路绝缘水平和安装引弧跳线等预防架空绝缘导线雷击断线的措施,现场运行表明,这些措施对预防绝缘导线断线事故的发生效果十分显著。
The lightning break accident often happened on 10 kV distribution grid overhead line insulation conductor,which seriously influence the power supply reliability of distribution lines.Through field investigation and a large number of theory analysis and calculation,the author analyses the reason and mechanism about aerial insulation wire lightning break accident,combined with the specific circumstances of a 10 kV power circuit in Hainan,and the measures for preventing the overhead insulation conductor from lightning break,such as improving line insulation level,installation of arc starting jump line and so on.The Field operation shows that the effect of these measures is notable for preventing insulation conductor break accident.
