摘要
介绍了基于气相色谱法的变压器状态判断方法。利用气相色谱法检测变压器绝缘油中特征气体的体积分数、产气速率等参数,根据参数的变化来判断变压器是否存在故障以及故障类型、故障部位,同时预测故障发生后的危险性、故障发展方向。以变压器铁心多点接地故障和变压器正常运行2种工作状态为例,进行实例分析判断,验证了该方法能够准确、及时地检测变压器内部故障。
This article introduces transformer adjudgement based on gas chromatographymethod.The volume fraction of characteristic gas among transformer insulation oil detectedby gas chromatographic method,which invovled whether there was a fault,fault type,andthe fault position,and predicting the risk of failure and the fault development direction.The example analysis of two functional modes of transformer core multiple point earthingfault and transformer normal running verified that the gas chromatography method coulddetect the the transformer internal fault correctly and timely.
