| 摘 要： | 对山茶籽植物绝缘油和矿物绝缘油两种变压器用油进行击穿放电故障试验,采用油中溶解气体分析方法测量并分析两种绝缘油放电故障所产生的油中溶解气体,分析并对比两种绝缘油纯油及油纸击穿产生气体的种类及百分含量。结果表明:两种绝缘油在击穿故障后均产生H_2、CH_4、C_2H_4、C_2H_6、C_2H_2、CO及CO_2这7种特征气体;随击穿故障次数的增加,植物绝缘油中溶解气体总量呈增加趋势,并且山茶籽植物绝缘油中CO和CO_2溶解气体含量大于矿物绝缘油;在两种绝缘油中,C_2H_2的含量在总烃中始终是最高的,这说明与矿物油相同,C_2H_2是山茶籽植物绝缘油电击穿故障的主要特征气体。

| Abstract: | The electrical breakdown of camellia seed vegetable insulating oil and mineral insulating oil transformer is simulated in experiments, respectively. The dissolved gas characteristics of two kinds of insulating oil are studied by means of dissolved gas analysis method. The type and percentage of gas produced by oil paper breakdown of the two kinds of insulating oil are analyzed and compared. Results show that the two insulating oils produce seven characteristic gases, i.e. H2, CH4, C2H4, C2H6, C2H2, CO and CO2, under the typical electrical faults. The total amount of gas produced in camellia-seed vegetable insulating oil increases with the increase of the times of breakdown, and the content of CO and CO2 produced by the insulating oil of camellia seed vegetable is greater than that of mineral insulating oil. The percentage of C2H2 is always the highest, which shows that C2H2 is the main characteristic gas of camellia-seed vegetable insulating oil breakdown. |
