大型输变电站电力变压器故障诊断系统

The Evelopment of Electric Transformer Trouble Diagnosis System in Larger Transformer Substation

为了及时发现电力变压器内部的潜伏性故障，提高设备运行的可靠性，开发研制了电力变压器故障诊断系统，实现对电力变压器运行状态的连续在线监测。本文就变压器内部故障的性质，类型，检测方法及故障诊断系统中的关键问题进行了论述。

In order to detect promptly latent trouble in inner of electric transformer, enhance operation reliability of devices, we developed this electric transformer trouble diagnosis system, which can implement continuous on-line supervision for operation state of electric transformer. This paper discussed the trouble characters, trouble types, detection methods and major technologies solved by this system.
