大型变压器漏（渗）油附件更换研究

在220kV及以上电压等级的变电站中,大型变压器作为中枢设备的作用举足轻重,但是由于运行时间过长或是外力因素的影响,变压器部分附件出现老化、变形等现象,从而导致了变压器局部附件出现漏(渗)油现象,此现象若不及时处理,将影响变压器安全稳定运行,使电网存在着极为严重的安全隐患,本文介绍大型变压器抽真空更换漏(渗)油附件的方法,可以消除变压器各类安全隐患,保证电网的可靠运行。

The Large-scale Transformer Leaks(infiltrates) the Oil Appendix Replacement Research

In 220 kV and in above voltage rank transformer substation,the large-scale transformer took the main center equipment the function is pivotal,but because the running time excessively is long perhaps the external force factor influence,the transformer partial appendices appear phenomena and so on aging,distortion,thus caused the transformer partial appendix to appear leaks (infiltrates) the oil phenomenon,if this phenomenon processed not promptly,will affect the transformer safe stable movement,caused the electrical network to have the extremely serious security hidden danger,this article through carries on to the large-scale transformer pulls out the vacuum to replace it to leak(infiltrates) the oil appendix,eliminated the transformer each kind of security hidden danger,guaranteed the electrical network the reliable movement.
