电力隧道内电力电缆线路的运行与维护研究苏天渭（成都电业局，四川省 成都市 610000）Research on Operation and Maintanance of The Cables Layed in Electric Power TunnelSU Tian-wei(Chengdu Power Supply Bureau,Chengdu 610000,Sichuan Province,China) ABSTRACT ：With the city's rapid development of economic construction, the demand for cables is gradually increasing and the electric power tunnel is also being widely used. Cables in electric power tunnel are commonly layed intensively, and the voltage of which are above 110kV’s high. How to strengthen the operation and maintanance of the cables which layed in electric power tunnel,how to improve the existing working environment of the cables and how to prolong the service life of the cables has become a important topic for us. In this paper, the routine operation and maintanance of the cables layed in electric power tunnel was discussed practicably.The author also analyzed problems existing and came up with feasible solutions.KEY WORD ： electric power tunnel;cable;layed intensively;service life; operation; maintanance摘要：随着城市经济建设的快速发展，电缆所占的比重正逐渐增加，而采用电缆隧道输送电力的情况也是越来越多。电力隧道内的电缆多为密集敷设，且均为110kV 及以上的高压输电电缆。如何加强电力隧道内电力电缆线路的运行维护与管理，改善现有电缆的运行环境，延长电缆的正常使用寿命，已成为摆在电力工作者面前的一项重要课题。本文结合生产实际，对电力隧道内电缆线路的日常运行维护工作进行了论述，并针对还存在的一些问题做出了深入地分析，提出了解决办法。关键词：电力隧道；电缆；密集敷设；使用寿命；运行；维护 1.引言电力隧道一般为地下封闭箱式结构，由混凝土浇筑而成。电力电缆安装敷设的方法及步骤会因电缆本身电压等级的差异而有所不同。本文以《电力电缆实用技术》为理论基础，对电力电缆隧道的日常维护与管理工作进行了全面、系统地论述，并结合生产实际，针对现阶段电力隧道的运行维护与管理过程中在“完善事故防护措施...
