摘要
介绍变压器状态评估方法,并分析了南方电网某局对其所辖的5个变电站(换流站)的110 kV及以上的变压器(电抗器)开展状态评估的案例。该案例参考了各个状态量进行综合评分,评估出变压器的状态等级,结果有参考价值。但评估方法中对不同状态量进行人工打分的做法受人为因素影响较大。
The condition assessment method of ransformers/reactors is introduced with a case analysis of 110 kV and above transformers/reactors in the five substations/converter stations of China Southern Power Grid.In the case analysis,the condition rank of the transformers/reactors is given according to the comprehensive evaluation of various condition variables,and the results are of reference.The evaluation method,however,is to be improved as it adopts artificial scording in the condition variable evaluation.
