摘要
高压隔离开关是变电站中的重要电气设备,长时间运行后会出现操作不到位的情况,严重影响电网运行的可靠性.以S3CT型隔离开关为例,对上海电网常见的水平旋转式双边双断口高压隔离开关的结构和原理进行了介绍,重点分析了该类型隔离开关操作不到位的原因,并给出了相应的处理建议.
Abstract
High voltage disconnectors are crucial electrical equipment in substations.After long time running,the inadequate operation of these switches can severely affect the reliability of the power grid.Taking the S3CT model as an example,this paper introduces the structure and principles of the commonly used horizontal rotary bilateral double-break disconnector in the Shanghai power grid.It analyzes the causes of inadequate operation for this type of isolating switch and provides recommendations for addressing these issues.
