摘要

作为有载调压变压器中唯一一个需要进行机械动作的部分

有载分接开关（OLTC）需要长期多次承载大电流开断闭合的任务

因此故障率非常高

而作为变压器中重要的部件

OLTC的正常工作直接关系到变压器以及整个电网的正常安全运行

因此其故障诊断成为研究的热点。OLTC的故障诊断又分为离线手段和在线手段

而作为能够在运行状态下检测OLTC的机械状态

减少停电造成的经济损失

在线检测手段受到更多的关注。近年来研究最多的在线故障诊断方法即为基于振动信号的OLTC诊断方法

为此总结梳理了OLTC基于振动信号进行故障诊断的近年来的研究成果

并提出了对未来研究方向的展望。

Abstract

As the only part of the load regulating transformer that needs to carry out the mechanical action

OLTC requires a long time to carry large current and break the closure

so the failure rate is very high. As an important part of the transformer

the normal work of OLTC is directly related to the normal power of the transformer and the whole power grid. Because of its safe operation

its fault diagnosis has become the focus of research.The fault diagnosis of OLTC is also divided into off-line means and online means

but as a mechanical state that can detect OLTC in the running state and reduce the economic loss caused by blackout

the online detection means receive more attention.In recent years

the most research method of on-line fault diagnosis is OLTC diagnosis method based on vibration signal. This paper summarizes the research results of OLTC based on vibration signal fault diagnosis in recent years

and puts forward the prospect of future research direction.
