电容式变压器套管介损数据异常案例分析

The Case Study of Abnormal Dielectric Loss Data of Capacitive Potential Transformer Bushings

分析比较了山西省电力公司长治供电分公司所辖变电站出现的两支电容式主变压器套管介损数据异常的情况,建立了电容式主变套管的相关模型,探讨了电容式主变压器套管介损数据异常的原因,并对预防类似情况的发生提出四点建议,对处理电容式主变压器套管介损数据异常有一定的借鉴作用。

Abnormal data of dielectric loss of two capacitive potential transformer bushings in the substations under the governance of Changzhi Power Supply Company is analyzed in this paper. Relevant models are established. The reasons that the data is abnormal are analyzed, and proposals for preventing the occurrence of similar situations are put forward. This paper has some reference to dealing with abnormal data of dielectric loss of capacitive main transformer bushings.
