摘要
上海中心城区10kV配网架空线路通道内,经常存在景观树木繁盛和小松鼠等小动物活动频繁情况。极易发生小动物攀爬配网设备、啃咬配网设备绝缘罩和树枝、鸟窝等异物搭接,造成配网故障跳闸,严重影响了供电公司的供电可靠性和服务水平。文章针对该类问题进行现状调研和原因分析,结合实际工作制订了防治措施,即通过配网架空线设备全绝缘化改造和加强配网精细化运行进行维护管理。经过实际运行,两个措施综合治理可以有效降低小动物侵入及异物搭接引发的跳闸次数,具有参考和推广价值。
In the 10 kV distribution network overhead line passage of the central urban area,there are often thriving landscape trees and frequent activities of small animals such as squirrels.As a result,it is extremely easy for small animals to climb the distribution network equipment,bite on the insulation cover of the distribution network equipment and overlap with foreign objects such as branches and bird nests,causing distribution network faults and trips,seriously affecting the power supply reliability and service level of the power supply company.This article conducts current research and cause analysis on such problems,and combines practical work to develop prevention and control measures:fully insulated transformation of overhead line equipment in the distribution network and strengthening of refined operation and maintenance management of the distribution network.After practical operation,two comprehensive measures can effectively reduce the number of trips caused by small animal invasion and foreign object overlap,which has reference and promotion value.
