摘　　要：分析了配电网各类防雷技术的技术性及经济性,针对10 kV电压等级配电网,提出了相应的防雷技术建议,涉及线路防雷和设备防雷两个方面,前者包括架空线路安装避雷线保护、线路避雷器保护以及架空绝缘线路"疏导式"防雷等,后者包括配电变压器防雷、变电所内的开关设备防雷以及户外线路开关设备防雷等,研究结果可为10 kV配电网的防雷提供参考。The technical and economic characteristics of various types of lightning protection technology were analyzed. Furthermore, the lightning technology proposals for 10 kV voltage level distribution network was given, including 10 kV distribution network line lightning protection and equipment lightning protection. And line lightning protection focused on the protection of overhead lines to install lightning conductor, line arrester protection and mediator-type lightning protection. Besides, equipment lightning protection focused on distribution transformers, substation switchgears and outdoor line switching equipments. The conclusions can provide references for the 10 kV distribution network lightning protection.
