高速公路机电工程防雷是高速公路机电建设不可缺少的一部分。近年来,高速公路雷击事件时有发生,造成的损失也是触目惊心的。2006年6月17日,吉林省磐石市呼兰公路收费站遭雷击,致使该收费站监控系统受损,影响了该站的正常工作。2006年7月12日,湖南某县电站发生雷击,强大电流通过照明线进入200米深的隧道,使隧道内照明线路全部打断,闸刀开关前部打坏起火,并致人员伤亡,如果高速公路防雷现状得不到改善或提升,随着我国高速公路网的不断延伸,防雷问题将进一步突出。如何防患于未然．从管理、设计、技术、施工等几个方面重视和规范高速公路防雷,成为高速公路建设大背景下一个应该日益得到重视的问题,希望这个专题能起到抛砖引玉的作用。
Lightning Electrical and Mechanical Engineering Highway is an indispensable part of the highway construction. In recent years, highway lightning incidents have occurred from time to time, the resulting loss is shocking. On June 17, 2006, a lightning strike struck the Hulan Highway toll station in Panshi City, Jilin Province, causing the toll station monitoring system to be damaged, affecting the normal operation of the station. On July 12, 2006, a lightning strike occurred at a county power station in Hunan Province. A strong current entered the 200-meter-deep tunnel through the lighting line, which interrupted all the lighting lines in the tunnel. The front of the knife switch broke the fire and caused casualties. The current situation of highway lightning protection can not be improved or improved. With the continuous extension of the expressway network in our country, the problem of lightning protection will be further highlighted. How to take preventive measures. From the aspects of management, design, technology and construction, attention and regulation of highway lightning protection become a problem that should be paid more and more attention in the background of expressway construction. We hope this project can play a valuable role.
