| 摘要: |
| 分析了SF6气体分解产物检测方法，开展了气体绝缘开关设备（GIS）设备分解产物带电检测，对检测结果进行了统计分析，得到了不同类型设备中的分解产物特性。统计分析结果表明，正常运行设备均未检测到SO2和H2S组分，50 % 以上的设备检测到CO组分但含量不超过20 μL ／ L，互感器检测到CO组分概率稍高且含量较大。对检测到SO2组分的设备气室进行了跟踪检测，结合设备运行工况，对设备状态进行了综合判断，通过解体检查验证了SF6气体分解产物检测措施及状态监测结果的有效性。 |

| Abstract: |
| The method of SF6 decomposition products detection is analyzed and the online decomposition products detection is carried out for different grid GISs（Gas-Insulated Switchgears）. The detection results are statistically analyzed and the decomposition products characteristics of different GISs are obtained，which shows that，no SO2 or H2S content is detected in normally operating GISs；more than 50 % of GISs contain CO with the concentration less than 20 μL／L；the probability of transducer containing CO and with higher concentration is big. The GISs containing SO2 are traced and combined with the operating conditions，their states are comprehensively estimated. The inspection by GIS disassembly verifies the effectiveness of the proposed detection method and monitoring results. |
