变压器为什么这么喜欢界面张力?

变压器为什么这么喜欢界面张力
Why do transformers like the interfacial tension so much?
变压器要作油对水界面张力的测定(园环法),油的流动性是用粘度来表述的,粘度低则流动性好,油对水界面张力的测定不是用来表征油的流动性能的。但油对水界面张力则反应的是油与水的亲合力,张力大则油水不易混容(乳化),油在精制中则易脱水(绝缘油的一重要指标是微量水PPM不能超标),油在运行中也不易吸水,故变油器油的标准中要规定其界面张力要大于一定的值。
The transformer to the determination of interfacial tension of oil (water park, the mobility of the oil ring) is used to describe the viscosity, low viscosity, good fluidity, oil to water Determination of interfacial tension is not used to characterize the flow properties of oil. But the oil water interfacial tension is the reaction to the oil and water affinity, tension is not easy compatibility (oil-water emulsion), oil refining is easy to dehydration (in insulating oil is an important index of trace water PPM cannot exceed the standard), oil in the operation is not easy to absorb water, so the oil is oil the standard to stipulate its interfacial tension is greater than a certain value.

Transformer oil pollution and oxidation of what to do?
如果变压器油受到污染或在运行中氧化、老化而生成一些微量新物质,毫无疑问都会使油对水界面的张力下降,张力的下降在某些方面又客观的反应了油中异物的多少,这些极微量的异物可能很难定性、定量的检测,但往往会对油的介质损耗有较明显的反应,虽说油对水的界面张力与油的介质损耗两者不是简单的线性关系,但绝缘油对水的界面张力,肯定会影响油与水混容的难易程度,油对水的界面张力小,油在脱气(脱水)精制过程就较难,所需时间较长,反之油也较易吸"潮",而众所周知:绝缘油中微量水的存在会对油的诸多性能有较大的影响。

If the transformer oil contamination in operation or oxidation, aging and generate some new trace substances, there is no doubt that will make the oil on the water interface tension decreased, tension decreased in some aspects and objectively reflect how much oil in the foreign body, the trace particle detection is hard to qualitative and quantitative, but often the dielectric loss of oil has obvious reaction, although both dielectric loss of oil on the water interfacial tension and oil is not a simple linear relationship, but the interfacial tension of insulating oil on the water, will certainly affect the degree of difficulty of oil and water miscibility, interfacial tension of oil on the water and oil in the degassing (dehydration) refining process is difficult, for a longer period of time, and is easy to absorb the oil boom, and as everyone knows: the trace water in the presence of insulating oil will have a greater impact on the performance of many oil.
