一种诊断变压器故障的方法及装置
摘要：
本申请公开了一种诊断变压器故障的方法及装置，涉及电力系统技术领域，尤为解决变压器故障诊断准确率低的问题而发明。采用的方法主要包括：获取变压器的绝缘油中溶解的气体浓度，所述变压器是存在确定故障类型的变压器；建立所述变压器的故障类型和所述气体浓度的故障对照表；将所述故障对照表中的数据作为训练样本和测试样本，构建并训练神经网络；将待诊断变压器绝缘油中溶解的待检测气体浓度输入到所述神经网络，诊断所述待诊断变压器的故障类型。本发明主要应用于诊断变压器故障。
摘要（英）：

The invention discloses a transformer fault diagnosis method and apparatus, relating to the technical field of a power system and particularly solving the problem of low fault diagnosis accuracy of a transformer. The method includes obtaining the dissolved gas concentration in the insulating oil of the transformer, wherein the transformer is a transformer having a determined fault type; establishing a fault parallel table of the fault types of the transformer and the gas concentration; taking the data in the fault parallel table as the training sample and the test sample, and constructing and training a nerve network; and inputting the concentration of the detected gas dissolved in the insulating oil of the transformer, and diagnosing the fault type of the transformer to be diagnosed. The transformer fault diagnosis method and apparatus are applicable to the transformer fault diagnosis.
