新型户外10 kV计量柜在某供电网的应用研究

Research on The Application of New Outdoor 10 kV Metering Cabinet in a Power Supply Network

近几年,因室外地面计量箱引发多起10 kV线路跳闸事故,对电力系统的安全、稳定运行造成了严重的威胁,并对广大人民群众的日常生活用电造成了严重的影响。为此,文章简要介绍A电力公司配电网在室外应用的10 kV计量箱中所遇到的故障,论述A电力公司应用城北分支10 kV线路室外智能断路器控制开关柜的技术设计思路和应用效果。

With the rapid development of social economy,people put forward higher requirements for the reliability of power system.In recent years,there have been many 10 kV line tripping accidents caused by outdoor ground metering boxes in urban areas of various regions,which has posed a serious threat to the safe and stable operation of the power system and had a serious impact on the daily power consumption of the people.Therefore,this paper briefly introduces the fault problems encountered in the outdoor application of 10 kV metering box in the distribution network of a power company,and discusses the technical design idea and application effect of applying the outdoor intelligent circuit breaker control switch cabinet of 10 kV line in Chengbei Branch of a power company.
