摘　　要：隔离开关又被称为刀闸,作为电力系统中的重要电气设备,主要起到承载额定电流及一定时间故障电流的作用,在特定的工况下起到接通和断开小电流电路及改变电力系统运行方式的作用。随着科学技术的飞速发展,高压隔离开关朝着大容量化、高电压和小型化方向发展,隔离开关运行中的发热问题也引起了人们的关注。发热问题不仅对电力系统正常运行构成威胁,还会影响企业的经济效益。论文分析了隔离开关发热的原因,对隔离开关检查处理方法和防范措施进行了探讨,以期为相关人士提供参考借鉴。The isolation switch is also called isolator.As an important electrical equipment in the power system,the isolation switch mainly plays the role of carrying rated current and fault current for a certain period of time,and plays the role of connecting and breaking small current circuit and changing the operation mode of the power system under specific working conditions.With the rapid development of science and technology,the high voltage isolation switch is developing towards the direction of large capacity,high voltage and miniaturization.The heating problem in the operation of isolation switch has also attracted people's attention.The heating problem not only threatens the normal operation of power system,but also affects the economic benefits of enterprises.This paper analyzes the causes of heating of the isolation switch,discusses the inspection and treatment methods and preventive measures of the isolation switch,so as to provide reference for relevant people.
