摘　　要：对绝缘材料受热时SF_6气体分解物中的SO_2和H_2S含量进行了详细的分析研究。通过大量的试验,分别研究和分析了电气绝缘材料加热时间、加热温度及SF_6气体的压强等因素对SF_6分解物中SO_2和H_2S含量的影响,并在各因素下对有吸附剂和无吸附剂时SO_2和H_2S含量进行了对比试验研究和分析。本文结果对根据SF_6分解物含量进行SF_6设备状态判断和缺陷、故障判断以及为电气设备带电检测提供参考。The paper analyzes ＆ studies the content of SO2 and H2S in SF6 gas decomposition when insulating material being heated. Based on lots of experimentation, the paper observes how the heating time ＆ heating temperature of the electrical insulating material and the pressure of SF6 gas react on SO2 and H2S, and also compares ＆ analyzes the content of SO2 ＆ H2S with and without adsorbent under every factor. Finally, the paper provides some insights in the study of the state ＆failure judgment of SF6 equipment and the live detection of electrical equipment based on the decomposition of SF6.
