10千伏架空线路、电力电缆线路是配电网重要组成部分,10千伏配电设备的安全运行与工矿企业、居民生活用电息息相关。近些年来,由于城乡建设的飞速发展,10千伏电力线路的外力故障呈多发态势,约占配网全部故障的60%以上,严重威胁线路的安全运行和正常供电。架空线路外力破坏的主要原因,主要在以下几方面:一是大型车辆刮撞电杆或拉线,造成电杆损坏、拉线断股或刮断,导致线路故障以及大型施
10 kV overhead lines, power cable lines are an important part of the distribution network, 10 kV distribution equipment, safe operation and industrial and mining enterprises, residential electricity consumption are closely related. In recent years, due to the rapid development of urban and rural construction, the external power failure of the 10-kilovolt power line shows multiple trends, accounting for more than 60% of the total faults in the distribution network, posing a serious threat to the safe operation of the line and normal power supply. Overhead lines of the main reasons for the destruction of external forces, mainly in the following areas: First, large vehicles scrape the pole or cable, resulting in damage to the pole, cable break or scraping, leading to line failure and large facilities
