摘要
配电网的运行状态直接影响着供电可靠性,而10 kV备自投装置能否准确动作是关键。针对一个10 kV配电站备自投装置误合分段断路器的案例,分析备自投动作逻辑,总结事故发生的原因,最后基于分析结论提出了防范措施。
The operating state of the distribution network directly affects the reliability of the power supply.Whether the 10 kV backup automatic switching equipment can accurately operate is the key point.Aiming at a case of a 10 kV substation′s backup automatic switching device wrongly closing the section breaker,the action logic of standby automatic switch was analyzed and the causes of the accident was summarized.Finally,based on the analysis conclusion,the preventive measures were put forward.
