摘要
为减少气体绝缘金属封闭式开关设备(GIS)产品运行期间的成本,必须改变维护方式,即从设备的定期维护改变到状态维护。文章介绍了GIS气体监视(如温度,压力,密度及含水量)、局部放电监测、断路器机械及电气性能监测等状态检测项目。这些监测的共用技术都是以传感器信息为基础的技术,应充分重视传感器技术。
To reduce the cost during operation for gas insulated and metal enclosed switchgear （GIS）, it must be changed for the maintenance way from periodic to condition - based. The items of condition - based maintenance were introduced： monitoring GIS gas （such as temperature, pressure, density and water content）; partial discharge monitoring; circuit breaker mechanism, electrical performante inspection. The common technology of these inspections is based on sensor technology, which should be paid more attention to.
