变压器油的三种主要保护措施

1.防止变压器油位过低
1. prevent transformer oil level is too low
变压器正常运行时油位的上升或下降,是由温度变化造成的,油位变化不会太大。当油位下降显著,甚至从油位计中看不见油位,则可能是因为变压器出现了漏油、渗油现象,这往往是因为变压器油箱损坏、放油阀门没有拧紧、变压器顶盖没有盖严、油位计损坏等原因造成的。油位太低会加速变压器油的老化,变压器绝缘情况恶化,所以要多巡视,多维护,及时添油。
When the transformer is in normal operation, the rise or fall of the oil level is caused by the change of the temperature, and the change of the oil level will not be too great. When the oil level drops significantly, even from the oil level gauge invisible level, it may be because the transformer oil leakage, oil leakage phenomenon, it is often because of transformer damage, oil discharge valve does not tighten, the transformer cover does not cover strictly, causes damage to the oil level gauge. Oil level is too low, will accelerate the aging of transformer oil, transformer insulation deterioration, so more visits, more maintenance, timely oil.
2.观察变压器是否漏油
2. observe whether the transformer leaks oil
发现变压器漏油要及时处理,如渗漏油严重,应及时将变压器停止运行并进行检修。检查时首先寻找漏油点,漏油故障比较容易发现,渗油故障则不易发现,一般尘土聚集且潮湿的地方渗油。若变压器油从上端盖上渗出时,应紧固上端一圈螺丝;若变压器油从挡位处渗出时,就应打开挡位盖,拧紧里边的压紧螺丝;若绝缘垫老化时,就应及时更换绝缘油垫。
Found that the transformer oil leakage should be dealt with in a timely manner, such as leakage of oil seriously, should promptly stop the transformer, and maintenance. When the inspection, the first to find oil spills, oil spills are relatively easy to find, oil seepage is difficult to find, general dust accumulation and moist place oil seepage. If the transformer oil leaking from the upper end cover, a top ring screw should be tightened; if the transformer oil leaking from the gear, it should open the gear cover, pressing screw inside; if the insulation pad aging, it should be timely replacement of insulating oil pad.

3.一闻两看辨别变压器油质量
3., one smell, two look, distinguish transformer oil quality
变压器油在使用1~3年时应做一次耐压试验。如果变压器油达不到技术要求,应尽早更换或过滤。由于对变压器油的质量要求很高,不经过耐压试验和简化试验很难说明变压器油是否合格,但经过长期的实践来看,变压器油的合格与否可通过一闻、两看来鉴别。
Transformer oil should be subjected to a withstand voltage test for 1~3 years. If the transformer oil does not meet the technical requirements, should be replaced or filtered as soon as possible. Because of the quality of transformer oil is high, without pressure test and the simplified test is very difficult to explain the transformer oil is qualified, but after long-term practice, whether or not qualified by a smell, it seems two differential transformer oil.
一闻:就是通过闻气味来鉴别变压器油质量,合格的变压器油应没有气味,或略带一点煤油气味。若有别的气味,说明油质变坏。
One smell: that is, through the smell to identify transformer oil quality, qualified transformer oil should be no smell, or with a little kerosene smell. If there is any other odor, it shows that the oil is bad.
两看:一看变压器油的颜色。新的变压器油一般是浅黄色,氧化后颜色会变暗。二看变压器油的透明度。新的变压器油装在玻璃瓶中是透明的,并带有蓝紫色的荧光,如果失去了荧光或不再透明,说明变压器油内已有游离碳和机械杂质。
Two see: look at the color of transformer oil. The new transformer oil is usually light yellow, and the color will darken after oxidation. Two look at the transparency of transformer oil. The new transformer oil is transparent in the glass bottle and has a bluish purple fluorescence. If the fluorescence is lost or no longer transparent, the free carbon and mechanical impurities are found in the transformer oil.
