摘要
对电力变压器抗短路能力的影响因素进行了分析,从短路校核、系统运行和试验情况三个方面,对老旧变压器抗短路能力进行综合评估,并给出了防止变压器短路损坏的措施和建议。
The factors affecting the short-circuit resistance of power transformers are analyzed.From the three aspects of short-circuit calibration,system operation and test conditions,the short-circuit resistance of old transformers is comprehensively evaluated,and the measures and suggestions for preventing transformer short-circuit damage are presented.
