The principle of measuring the interfacial tension of the insulating oil filter
2018/5/15 Viewers:
The interfacial tension of insulating oil refers to the tension produced by measuring the interface between oil and incompatible water. Usually, the interface of oil is: oil, gas, oil, liquid, oil and so on. The interfacial tension of insulating oil belongs to the category of oil.
In the theory of molecular motion of physics, there is a layer of surface layer on the surface of the liquid, and the force on the liquid surface is different from that in the inner liquid. This is because every molecule in the liquid is surrounded by a molecule of the same kind, that is, the attraction of the surrounding molecules is equal and the force can be counteracted by this, that is, the resultant force is equal to zero; and the gravitational force on the liquid surface or at the two intersecting interface is not equal because of the force field. Part of the surface is outside the surface, and the gravitational force of the ordinary surface molecules is often less than the gravitational force of the internal molecules, so the force field is uneven, or not the same. Because the attraction of the liquid molecules near the surface or interface is different, the liquid surface tends to shrink automatically. That is, the molecular attraction of the oil molecules on the interface layer is more attractive than the water molecules, which makes the oil surface produce a free surface energy that tries to shrink, as shown in Figure 2-2. In the process of forming the surface S, it is also necessary to consume a certain amount of work A:, which is proportional to the s of this table. The force of reducing the surface of the liquid is called the surface tension F, and its force is proportional to the length L of the interface. When the test liquid is used to contact the air (gas - liquid phase), the measured value is called surface tension; the measured value is called interfacial tension when the test liquid is in contact with other phase (liquid - liquid phase, such as oil - water).
The function of high efficiency vacuum insulation oil filter oil can quickly remove the moisture, gas and impurities in the insulating oil, as well as the harmful components in the acetylene, hydrogen and other oil, so as to improve the insulation performance of the oil, and can effectively ensure the safe and normal operation of the electric power equipment. The machine adopts the vacuum vacuum pressure principle to introduce the latest duplex three-dimensional flash technology in Germany, film evaporation technology and multistage precision filtration, so as to reliably remove the harmful substances such as water, impurity and gas in the unqualified oil, and quickly recover the oil performance to reach the oil standard. The equipment is especially suitable for advanced treatment of high-grade transformer oil and ultra high transformer oil, and can be used for live working in substations above 110KV. At the same time, the equipment has separate vacuum drying and vacuum oil filling function. It is suitable for purification and regeneration of various insulating oils in petroleum, chemical, mining, metallurgy, power, transportation, machinery manufacturing, railway and other industries.
