摘要
雷击引起的故障在10 kV架空线路总故障中占很大比重,随着线路绝缘化率的提高,雷击断线问题也变得越来越严重。因此有必要对10 kV架空线路防雷治理技术进行深入研究,提高10 kV架空线路供电可靠性。以东莞地区10 kV架空线路为研究对象,根据10 kV架空线路雷害发展过程提出防雷治理基本思想;分析了10 kV架空线路防雷措施技术经济性,得到了各防雷措施优缺点;根据不同的防雷治理目的,提出了依据线路重要等级性和地区雷电活动强烈等级性进行有针对性防雷改造的防雷治理原则,即重要线路和雷电活动强烈地区线路尽量选用"堵塞型"的防雷措施,其他一般线路尽量选择"疏导型"的防雷措施。
The fault caused by lightning striking in 10 kV overhead line fault accounting for a large proportion. With the increase of insulating process, lightning line-broken accidents problem has become more and more serious. So it is necessary to make further research in the technology of lOkV overhead line lightning protection treatment, and so as to improve the power supply reliability. By taking lOkV overhead line of Dongguan as the research object, the lightning protection is based on lightning disturbance. The technology and economy evaluation of lightning protection measures are analyzed, the advantages and disadvantages lightning protection measures are pointed out. According to different purpose, pertinent lightning protection treatment principles are proposed.
