摘　　要：辐射架空线路进线电缆更换过程中,若没有对侧电源转供,就会导致辐射架空线路上所有用户陪停,直到进线电缆更换完毕。该方法存在停电时户数损失巨大,严重影响供电可靠性的缺点,因此提出一种辐射架空线路进线电缆更换方法,最大限度减少停电时户数损失。重点介绍了该方法的实施过程和应用优势。During the process of replacing the incoming cable of the radiating overhead line,because there is no power supply from the opposite side,all users on the radiating overhead line will be shut down until the incoming cable is replaced.This is a huge loss of households during power failure,which seriously affects the reliability of power supply.Therefore,a replacement method of incoming cable of radiation overhead line is proposed to minimize the loss of households during power failure.The implementation process and application advantages of this method are mainly introduced.
