摘　　要：架空线路大多数的故障是瞬时的或者暂时的,线路保护动作,故障消失后重合闸经短时间间隔后使断路器合上,从而缩短了线路停电时间,提高了供电的可靠性.因此,主要分析海南海口110 kV遵谭站35 kV遵发线过流保护动作后重合闸不出口的问题,并提出相关的整改措施.Most faults of overhead lines are instantaneous or temporary line protection actions.After the fault disappears,the recloser closes the circuit breaker after a short time interval,thereby shortening the line blackout time and improving the reliability of power supply.This article mainly analyzes the problem that the reclosure does not exit after the overcurrent I protection action of the 35kV Zunfa Line of Haikou 110kV Zuntan Station in Hainan,and Propose rectification measures.
