摘要
以广州华润热电有限公司220kV润洲联线隔离开关气室的故障为例,介绍了运用气相色谱-质谱联用技术进行SF6气体绝缘金属封闭开关设备(gas insulated metal enclosed switchgear and controlgear,GIS)故障分析的方法。该方法利用气相色谱和质谱图分析GIS故障时SF6的分解产物,根据分解产物的特征性判断设备的故障类型。
The paper takes the gas chamber fault of 220 kV Runzhou online disconnector in Guangzhou China Resources Thermal Power Corporation as an example and introduces fault analysis method for gas insulated metal enclosed switchgear and controlgear (GIS) of SF6 by applying GC-MS technology. The method analyzes decomposition products of SF6 in condition of GIS fault by the use of GC and MS. it diagnoses fault types of the equipments in line with features of decomposition products.
