摘要
利用变压器油中溶解特征气体的组分和含量可识别变压器潜伏性故障,介绍大型电力变压器油中总烃含量超标的综合分析和处理过程,通过变压器油中特征气体注意值、产气速率以及变压器的运行状况等因素,对变压器故障类型进行了分析,并结合电气试验、变压器的负荷变化及潜油泵的辅助检查,对故障部位进行了初步判断。
Composition and content of dissolved gas in transformer oil can indicate latent transformer fault. This study introduces the analysis and treatment of over - proof of total hydrocarbon content in main transformer oil. Based on the typical concentration values, typical growth rates of characteristic gas in transformer oil as well as operating conditions and structural characteristics of the transformer, the fault types were analyzed. And com- bined with electrical tests, load changes of transform and accessional examinations of oil circulating pump, the fault locations are determined.
