摘要
在区别线路反击和绕击的基础上 ,对典型的线路绕击故障进行了分析。指出绕击是造成陕西省山区内 330kV线路雷击跳闸的主要原因 。
Some shielding failure faults happened on typical HV transmission line are analyzed in this paper. It is presented that shielding failure is the main reason causing lightning trip on 330kV transmission lines in Shaanxi Provinces mountain area. It is suggested to adopt complex technique of lightning protection for HV transmission lines to reduce lightning trip-out rate.
