摘　　要：在配电设备中,跌落式开关(熔断器)作为用户进线开关被广泛应用。通常熔断器发生故障后需采取带电作业方式进行检修,一种作业方式为带电不带负荷更换,需拉开熔断器使用户停电,另一种方式为带电带负荷更换,能够实现用户完全不停电。现行的带电带负荷更换熔断器作业方式存在危险点多、操作复杂等缺点,针对此问题,提出了一种使用旁路系统运行正确性校核的熔断器检修方法,以保障检修过程中的人身安全和设备安全。In distribution equipment,dropout switches(fuses)are widely employed as user incoming switches.Typically,when fuses malfunction,maintenance is performed under live operation.One method involves live replacement without load,requiring the fuse to be pulled to disconnect power for the user.Another approach entails live replacement with load,enabling complete user power continuity.However,the existing live replacement with load method for fuses exhibits drawbacks such as multiple danger points and intricate procedures.Aiming at addressing this issue,a method for maintenance of fuses using bypass system operational verification is proposed,ensuring personal and equipment safety during the maintenance process.
