浅谈110kV高压输电线路的防雷保护

On the 110kV High Voltage Transmission Line Lightning Protection

在电力系统中,由于架空输电线路所处的地理环境,相对于电力系统的其他设备,架空输电线路遭受雷击的几率远远大于其他系统。章结合宿迁地区110kV高压输电线路的雷害情况,通过对雷击线路的危害及线路雷击跳闸的两种主要表现形式的特点进行了介绍和分析,并结合架空线雷害事故的形成的4个阶段特点和多年运行实践经验提出了防范保护措施。

In the power system,due to overhead transmission lines in which the physical environment,relative to the power system and other equipment,overhead transmission lines being struck by lightning the chances are far greater than other systems.S combination of Suqian regional 110kV high voltage transmission line mine-affected situations,through the lightning line lines lightning trip hazards and the two main manifestations of the characteristics of the description and analysis,combined with overhead line lightning disturbance of the formation of four stages of characteristics and years of practical experience of running a preventive protective measures.
