Abstract:As the development of economy and society, the amount of medium voltage switch cabinets used is getting larger. C-GIS which could not be affected by external environment is increasingly well received for its small-size, maintenance-free and high reliability in recent years. In this paper, development history and features of C-GIS are reviewed, several common products are introduced and development trend of C-GIS is summarized and forecasted. Environment friendly and intelligent C-GIS would be the development direction and applied progressively in rail transportation and distribution network.
Key words:C-GIS; development trend; environment friendly; intelligent
1 引言
柜式氣体绝缘金属封闭开关设备(Cubical Gas Insulated Switchgear),简称C-GIS,是一种以断路器为主开关,用于10~35kV或更高电压等级的一次配电系统设备。充气环网柜以负荷开关为主开关,也有配断路器的方案,用于10~35kV的二次配电系统。充气柜通常是C-GIS与充气环网柜的统称。
充气柜利用GIS的绝缘技术、密封技术将高压元件安装在箱型密封容器内,并充入略高于大气压力的绝缘气体,利用现代先进的加工工艺制成成套系列化产品,在系统正常和故障情况下具有对电能分配的控制、保护、测量、监视和通讯功能。相对于传统非密闭的移开式空气绝缘开关柜,具有密封充气的特点。
2 充气柜特点与使用场合
充气柜的整个高压系统处于完全密封的状态,不受外界环境条件的影响,缩小了柜体外形尺寸,具有整体小型化、高可靠性、免维护的特点,由于在工厂整体组装后运往现场,现场安装方便,运维成本低,整个生命周期具有较高的性价比和可靠性。……
