变压器的常见故障及处理

Common Failures and Treatment of transformers

变压器是电力系统中的一个关键设备,它的良好运行对电网安全具有重要的意义。目前变压器运行可靠性在不断提高,但变压器事故和故障还是不断发生。在故障较轻时,变压器虽能继续运行,但存在一定的安全隐患,必须严密监视变压器的运行状况,及时排除变压器的故障避免事故范围扩大。文章介绍了变压器运行过程中几种常见的故障情况、判断和处理方法。

Transformer is key power system equipment,which good running has great significance for grid security. Current transformer operating reliability improved gradually. But the transformer malfunction or accident occurred continuously. When the fault is light,transformer will be able to continue to operate,but there are some security risks. So we must closely monitor the health of the transformer,which was timely troubleshot to avoid the accident scope. This article described the process of transformer operation in several common fault conditions,judgment and treatment.
