摘　　要：在我国用电需求日益增加的今天,供电方式也随之改变,由原来的架空线供电方式逐步向电缆供电模式转变。根据有关资料,10kV配网线路调查结果中电缆使用量的所占比例远远大于架空线。但随着电力电缆的广泛使用,电缆的故障也随之增加,不利于运行管理部门进行检测,增大了管理的难度,影响电网的供电可靠性。基于电缆结构的基本特征,对造成电缆的事故原因和类型进行分析,探究处理电缆故障的具体应对措施,从而最大限度降低电缆故障的发生概率,确保电网安全稳定的运行。With the increasing demand for electricity in China,the power supply mode has also changed,gradually shifting from the original overhead line power supply mode to the cable power supply mode.According to relevant information,the proportion of cable usage in the survey results of 10 kV distribution network lines is much higher than that of overhead lines.But with the widespread use of power cables,the number of cable faults has also increased,which is not conducive to detection by operation management departments,increases the difficulty of management,and affects the reliability of power supply in the power grid.Based on the basic characteristics of cable structure,this article analyzes the causes and types of cable accidents,explores specific measures to deal with cable faults,in order to minimize the probability of cable faults and ensure the safe and stable operation of the power grid.
