摘要
GIS设备发生SF6气体泄漏会导致其绝缘性能下降,并对大气环境造成严重的污染。红外成像法利用SF6气体特定的红外吸收光谱,能使泄漏气体清晰可见,进而可以在设备不停电的状况下对泄漏部位进行快速、准确的定位。检测实例表明该方法直观有效,为漏气设备检修策略的制定提供了充分的信息支持。
SF6 gas leakage occurred in gas insulated switchgear（GIS） can lead to insulation degradation and serious pollution on atmospheric environment.Based on the specific infrared absorption spectrum of SF6 gas,infrared imaging method can make the leakage gas clearly visible.As a result,it can rapidly and accurately locate leakage position for on-line equipments.It is concluded from the detection examples that this method is visual and effective for SF6 gas leakage,and can provide sufficient information for the maintenance strategy of gas leaking equipment.
