摘要
10 kV电网设备中GN30、GN22两种类型大电流隔离开关广泛应用在变电站XGN-12型高压柜中,但GN30型隔离开关因设计缺陷等原因,近几年频繁出现发热现象。文章在研究GN30型隔离开关结构的基础上,对GN30型隔离开关发热原因进行分析研究,针对GN30型隔离开关故障现象及其解决方案给出一些思路和建议。
In 10 kV power grid equipment,GN30 and GN22 two types of high-current isolation switches are widely used in XGN-12 high-voltage cabinets in substations.However,due to design defects and other reasons,the GN30 type isolating switch has frequently heated up in recent years.Based on the research of the structure of the GN30 isolating switch,the causes of the GN30 isolating switch heating were analyzed and studied.
