摘要(Abstract)：
化学诊断法是一种有效的SF6电气设备绝缘状态监测手段,但该方法在推广应用的过程中也受到一些因素的干扰,如吸附剂对局部放电特征气体的吸附作用、气室内水分含量差异对分解产物变化规律的影响、检测容器吸附等因素的干扰。为此,通过设置多组试验,系统研究了上述因素对主要SF6分解产物变化规律的影响,为提高化学诊断法用于设备绝缘监测的准确度奠定了基础。
The chemical diagnosis method is an effective means to monitor the insulation condition of SF_6 electrical equipment. However, this method is also affected by some factors in the process of popularization and application such as the adsorption of adsorbents on the partial discharge characteristic gas, influence of moisture content difference in the air chamber decomposition on the product change law, the interference of detection container adsorption. In this paper, the influence of the above factors on the variation of SF_6 decomposition products is studied by multiple tests, which lays the foundation for improving the accuracy of chemical diagnosis method for equipment insulation monitoring.
