摘　　要：目前OPGW光缆可采用逐塔接地、分段绝缘单点接地、全线绝缘单点接地3种接地方式,不同接地方式将影响到以下几个方面:接地方案的实现(设备及安装)、正常运行状况、故障运行状况、防雷性能、运行维护、安全可靠性等。对OPGW 3种接地方式进行综合分析对比,给出了可供工程设计和运行参考的建议。Three grounding methods of optical ground wire （OPGW） are adopted in ultra - high voltage transmission network, that is, grounded at every tower, grounded at one single point in one line section and grounded at one single point insulated entirely in whole line. Various aspects of OPGW projects such as the implementation of grounding equipment and installation, the normal operation condition, the fault state, lightning protection performance, operational maintenance and reliability etc. will be affected by different grounding methods. The comprehensive analysis and comparison among three grounding methods of OPGW are carried out and the suggestions are provided to the engineering design and operation for reference.
