摘要
研究分析了降低线路杆塔接地电阻,架设避雷线路,加强线路运行维护以及采用不平衡绝缘方式与装设自动重合闸这些输电线路防雷的常规措施。针对近年出现的架设耦合地线,调节保护角,安装喷射气流灭弧防雷保护间隙装置,安装线路避雷器,加侧向避雷针,架设可控放电避雷针,安装架空地线避雷针,安装线路塔头避雷器等新型防雷措施做了重点分析,对输电线路防雷的理论研究及工程实践都一定的指导意义。
This paper research and analysis on the following conventional measures of lightning protection: to reduce lines tower grounding resistance, to erect line lightning arrester, strengthen line operation and maintenance, using the unbalanced insulation way and setting up automatic reclosing. Some new measures of lightning protection in recent years are analyzed, such as erecting coupling ground line, regulating protection angle, installing spray airflow eliminates arcing lightning protection gap device, installing line lightning arrester, adding lateral lightning rod, setting up controllable discharging lightning rod, installing overhead grounding line lightning rod and installing lines tower head lightning arresters and so on. It has certain guiding significance for doing theoretical research and engineering practice of transmission lines lightning protection.
