摘　　要：随着电网系统对供电可靠性和持续性要求的提高,为实现不停电对已有的变电站进行扩建、检修、现场交接绝缘试验等,需使用一种双断口隔离开关配合一把临时接地开关,以有效解决这些问题。同时,通过合理设计双断口隔离开关结构,可有效兼容现有的设备、间隔,提高设备的可互换性和后期的可维护性。With the increasing demand for power supply reliability and sustainability in the power grid system,in order to achieve uninterrupted expansion,maintenance,and on-site insulation testing of existing substations,it is necessary to use a double-gap disconnector in conjunction with a temporary earthing switch to effectively solve these problems.At the same time,through the reasonable design of the double break isolation switch structure,it can effectively be compatible with existing equipment and intervals,improve equipment interchangeability and later maintainability.
