摘要
GIS是广泛应用于我国电网系统的特殊电气设备组合,全称GAS INSULATED SWITCHGEAR,中文名称为气体绝缘金属全封闭组合电器,组成部分主要为:断路器、隔离开关、接地开关、互感器、避雷器、母线、连接件以及不同功能的开关.GIS设备组件大多以金属接地外壳封闭,外壳中存在绝缘压力气体,其设备性能和优越性高于大部分常规开关设备,可靠性强,这些基本特征使得GIS在我国电网系统具有良好的适用性和广泛的应用率.本文深入分析GIS电压互感器检测试验方法,解决GIS电压互感器的误差试验,对于保障电力系统安全生产具有重要意义.
GIS is a special combination of electrical equipment widely used in China’s power grid system.Its full name is gas insulated switchgear,and its Chinese name is gas insulated metal totally enclosed combined electrical equipment.The main components are:circuit breaker,disconnector,grounding switch,transformer,lightning arrester,bus,connector and switches with different functions.GIS equipment components are mostly enclosed by metal grounding shell,and there is insulating pressure gas in the shell.Its equipment performance and advantages are higher than most conventional switchgear,and its reliability is strong.These basic characteristics make GIS have good applicability and wide application rate in China’s power grid system.It is of great signifi cance to analyze the test method of GIS voltage transformer and solve the error test of GIS voltage transformer.
