SF6分解产物组分与SF6电气设备的绝缘缺陷密切相关。通过气质谱联用仪检测SF6分解产物组分可以全面评价SF6电气设备的运行状况。通过研究色谱柱温度、进样口温度、进样分流比、载气流量等分析条件的改变对检测结果的影响,探讨了气质谱联用仪检测SF6分解产物组分的最佳分析条件,并建立了检测方法。指出应用检测方法对SF6运行气、故障气进行检测,有助于SF6电气设备运行状况评估和状态检修。

The composition of SF6 decomposition products is closely related to the insulation defects of SF6 electrical equipment. The performance of the SF6 electrical equipment can be fully evaluated by measuring the composition of the SF6 decomposition products by GC / MS. By analyzing the influence of the column temperature, inlet temperature, injection split ratio and carrier gas flow on the detection results, the optimum analytical conditions for detecting the components of SF6 decomposition products by GC / MS were discussed. Established a test method. It is pointed out that the detection method of SF6 running gas and fault gas can be used to evaluate the operating status of SF6 electrical equipment and to check the condition.
