摘　　要：含水量是影响变压器绝缘性能的关键因素之一,因此对变压器含水量的监测尤为重要。以某水电站变压器受潮事故为案例,采用DIRANA介质谱分析仪开展变压器含水量现场检测分析试验,并结合变压器绝缘检测试验、变压器常规/特殊试验结果,验证了DIRANA介质谱分析仪检测结果的有效性和准确性,为变压器含水量的宽频、无损检测提供了理论依据,也为变压器绝缘性能的现场诊断提供参考。As moisture is one of the key factors affecting the insulation performance of transformers,monitoring the moisture content of transformers is particularly important.Taking a transformer moisture accident in a hydropower station as an example,the DIRANA media spectrum analyzer is applied to carry out on-site detection and analysis tests of the moisture content in the transformer.Combined with the tests from transformer insulation tests and the transformer routine/special test,the validity and accuracy of the DIRANA media spectrum analyzer test results are verified,which offers a theoretical basis for broadband and non-destructive testing of the transformer moisture content as well as reference for on-site diagnosis of transformer insulation performance.
