电力架空光缆防松鼠破坏问题探讨与实践

Investigation and Practice of Protecting Electrical Aerial Cables From Squirrel's Damage

在成都地区,电力架空光缆被松鼠啃咬造成断线而导致的通信中断故障是一种典型的光缆故障,为了防治这种典型的光缆故障,通过对不同方案进行对比分析,并结合使用效果,对架空光缆防松鼠破坏问题进行了探讨,最终确定了一种加装PE护套和挡鼠板相结合的治理方法。以国网成都供电公司110 k V青城山站至35 k V石牛站段光缆为例,对此种方法进行了实际安装试运行。经过实地测试,可以看出此方法能够有效防止松鼠破坏光缆,达到预期目标。

It is a typical optical cable fault that the electrical aerial cables are damaged by squirrels＇ bite in Chengdu area. To renovate the malfunctions above, through comparative analysis of different schemes and their using effect, this paper discussed the damage of electrical aerial cables caused by squirrels＇ bite and proposed a solution of installing PE sheath and rat guard. It was applied in mountain 110 k V Qingcheng Station and 35 k V Shiniu Station of State Grid Chengdu Electric Power Supply Company. Field tests have proven that this method can effectively prevent the squirrels to damage the fi ber optic cable and meet the expected goal.
