架空输电线路雷电防护
摘要：架空输电线路防雷是电力系统防雷工作的重要方面，常用的防雷措施有：架设避雷线、降低杆塔接地电阻、架设耦合地线、加强线路绝缘、采用不平衡绝缘方式、安装线路避雷器等。真正解决线路的雷电防护问题，还要从实际出发，因地制宜，综合治理，采取切实可行的方法，才能达到预期目的。

the overhead transmission lines and lightning protection sunzongyi
(meteorology bureau of pingyi city273300,china) abstract：the overhead transmission lines is lightning protection power system of the most important aspects of the lightning protection work, the commonly used lightning protection measures are: set up bileixian, reduce the tower grounding resistance and laying coupling, and strengthening the line insulation wire, using the unbalanced insulation way, installation line lightning arrester, etc. really solve the lines and lightning protection problems, but also from the reality, adjust measures to local conditions, the
comprehensive management, take practical and feasible method, can achieve the desired result.
