摘　　要：当电力用户内部系统发生故障时,能否从公用电网快速切除,防止用户故障引发公用线路停电,是确保电网安全稳定运行和提升供电可靠率的关键。用作切除用户故障的传统断路器往往存在故障时误动、拒动、动作慢等情况,将被能够精准识别各类故障、并通过快速分闸自动隔离故障的智能断路器所替代。故合理地配置中压用户的分界点智能断路器是当前提升配电网装备水平的一项重要工作。When the internal faults of power users occur,it is the key to ensure the safe and stable operation of the power grid and improve the reliability of power supply whether the power grid can be quickly removed from the public power grid and prevent the power outage caused by the user fault.The traditional circuit breaker used to cut off the user’s fault often has misoperation,refuse to move and slow action when the fault occurs.It will be replaced by the intelligent circuit breaker which can accurately identify all kinds of faults and automatically isolate the fault through rapid opening.Therefore,it is an important work to reasonably configure the dividing point intelligent circuit breaker for medium voltage users to improve the level of distribution network equipment.
