GIS/GCB气体绝缘电器设备的状态维护技术

Status Maintenance Technique for GIS/GCB Gas Insulation Electrical Equipment

为减少GIS/GCB产品运行期间成本,必须改变维护方式,即从设备的定期维护改变到状态维护。介绍了状态检测项目:监视GIS气体(温度、压力、密度及含水量);局部放电监测:断路器机械、电气性能监测。认为这些监测的共用技术都是以传感器信息为基础,要给予充分重视。

In order to reduce the cost in GIS/GCB product operation period,maintenance method must be changed,that is to say from periodical maintenance to be changed to status maintenance.The items of status testing are introduced as:GISgas (temperature,pressure,density and moisture)monitoring; partial discharge monitoring;and monitoring for the circuit-breaker mecha-nism and electrical performance.And it is considered that common techniques for these monitorings are all based on sensor's information,which should be paid to with great attention.
