摘要
变压器故障诊断应综合各种检测手段和方法,对各种检测结果进行综合分析和评判。根据DL/T596—1996《电力设备预防性试验规程》规定的试验项目及试验顺序,通过变压器油中气体的色谱分析方法,在不停电情况下,对变压器内部某些潜伏性故障及其发展程度的早期诊断非常有效。
Transformer fault diagnosis should utilize various detecting method,and makes comprehensive analysis and estimation for the detecting result.According to the stipulated testing items and sequence of DL/T596-1996 Preventive test code for electric power equipment,the paper introduces the method of chromatographic analysis for gases in oil-filled transformer,it can effectively diagnosis some potential fault in transformer and its degree under power-on inspection.
