摘要
通过检测GIS设备中SF6气体分解产物对设备内部绝缘进行故障诊断和状态评估,具有抗干扰能力强、灵敏度高等特点,正在被应用于设备现场检测分析。笔者分析了SF6分解产物不同检测方法的特点,选用适合现场检测的方法和仪器,对耐压试验后的设备进行气体成分分析,根据SF6分解产物的组分及体积分数进行设备的状态评价和故障诊断。
The method of fault diagnosis and condition evaluation for internal insulation of GIS equipment by measuring SF6 decomposition products is with the advantages of strong anti-interference ability and high sensitivity,so it is applied in the field test of equipment.Different test methods were introduced in this paper.Some on-site analytical methods and instruments were used to the analysis for gas components of GIS after a withstand voltage test.According to the analysis,GIS equipment status evaluation and fault diagnosis can be carried out.
