摘　　要：随着电力通信骨干网OPGW光缆传输的迅猛发展,OPGW光缆进站引下因雷电和感应电导致电蚀、断股等现象时有发生,严重影响到电力通信网的安全可靠运行。通过对变电站门型构架结构与存在问题的深入研究,结合相关标准规范要求,提出有户内变电站特点的OPGW光缆引入落地余缆箱绝缘工艺四点接地方案。With the rapid development of OPGW optical cable transmission in the power communication backbone network,the phenomena of electric corrosion and strand breaking caused by lightning and induced electricity when OPGW optical cable enters the station occur from time to time,which seriously affects the safe and reliable operation of power communication network.Based on the in-depth analysis and Research on the structure and existing problems of substation portal frame,combined with the requirements of relevant standards and specifications,a four point grounding scheme for introducing OPGW optical cable with the characteristics of indoor substation into the insulation process of floor residual cable box is proposed.
