Abstract:

由于O2直接参与SF6过热分解组分的生成过程,而目前有关其作用机制与宏观规律尚不完全清楚,因此亟需了解微量O2对SF6过热分解特性的影响规律,为建立有效的SF6气体绝缘装备过热故障诊断方法提供参考。该文在已有的SF6过热分解模拟实验系统上,对不同比例的SF6/O2混合气体进行大量的过热分解实验,获取微量O2对SF6过热分解组分的有效产气速率和特征比值的影响规律,进而研究微量O2对分解组分形成过程的影响机制。结果表明:微量O2对SF6的主要过热分解组分H2S、CO2、SO2F2、SOF2和SO2的有效产气速率均有一定的影响,但影响规律因组分的差异而不同,致使表征局部过热性故障属性的特征分解组分比值因O2含量的不同而发生变化,但二者有较为明显的关联关系。
