摘　　要：SF6开关设备发生故障或存在缺陷时,设备内部会产生SF6分解产物,通过检测这些分解产物为设备故障定位和缺陷诊断提供了有效手段。试验研究了SF6开关设备在不同开断电流、不同燃弧时间以及有无吸附剂情况下SF6气体分解产物的变化情况,分析了设备在电弧放电故障时SF6气体分解产物体积分数变化趋势及影响因素,为设备的故障诊断提供了有效手段。Faults or defects in SF6 switching equipment induce decomposition of SF6 gas. Correspondingly, the faults and defects can be diagnosed and located through detection of SF6 decomposition products. Experiments were conducted to obtain content variations of SF6 decomposition products under the stress of electrical arc in an SF6 switchgear with different current, arc time, and adsorbent. Content variation trend of SF6 decomposition products for a partial discharge fault and the influencing factors were analyzed. Thus, an effective means of fault diagnosis for SF6 switching equipment is provided.
