风沙气候对电力光缆通信线路的影响分析

Analysis on impacts of sandstorm on electric power optical communication cable lines

电力光缆多随电力杆塔建设,因此多为架空线路,经常会遭到风沙灾害破坏。文章从短时剧烈破坏与长期缓慢风蚀两方面,针对风沙灾害对光缆正常运行的影响进行了说明,分析了短期剧烈破坏与长期缓慢风蚀对光缆线路的主要危害。选取现场实际运行的光缆线路进行测试,并对测试结果进行了分析。同时,还选取现场常用光缆在实验室进行了测量。结合现场及实验室的测试结果,综合现场运行经验,给出了关于光缆线路中如何应对短时剧烈破坏与长期缓慢风蚀影响的建议。

Mostly built on the electric power towers as overhead lines, electric power optical communication cable lines are often subject to sandstorm destructions. In view of the their impacts on the normal operation of the cable lines, this paper explains the destructions in two aspects, short-term severe damage and long-term slow erosion and describes the relevant damages and harms to these lines. In addition, it performs tests on the selected optical cable lines in actual field operation, analyzes the test results and measures the commonly used cables in the lab. On the basis of the field and laboratory test results and the field op- eration experience, it gives suggestions and advices for coping with short-term severe destruction and long-term slow erosion effect on the optical cable lines.
