摘　　要：对发电厂直配线路的防雷保护现状进行了分析和探讨,对发电机的耐雷水平进行了讨论,对目前一些直配线路的防雷保护缺陷进行了分析,提出了用避雷器、电抗器和电缆联合配置的发电厂直配线路的综合防雷保护措施,并且对直配线路所用避雷器选型、安装和运行维护以及防雷装置的接地问题都提出了一些改进建议.The situation of lightning protection for direct distribution lines in power plant is discussed. The lightning-resisting level of generators and the defects of lightning protection for direct distribution lines are also analyzed.Based on the above analysis, the comprehensive measures of lightning protection is put forward for direct distribution lines in power plant which is composed of lightning arrester, reactor and cable. And some good advice on selection, setting and maintenance of lightning arrester and lightning protection device used in direct distribution lines is also given.
