Insulating oil breakdown voltage detection (insulating oil vacuum oil purifier)

　　Causes of transformer oil contamination:

　　After long-term use of transformer insulating oil, the oil will change, and it will contain moisture, impurities, and colloidal particles. At the same time, it will affect the breakdown voltage and dielectric loss of the oil. Therefore, it is necessary to filter with a vacuum oil filter to restore the breakdown voltage performance of the oil.

　　1. Moisture is the most common and the most sensitive stolen goods that affect the breakdown voltage. Because water is a polar molecule, under the action of electric field force, it is easy to be elongated and arranged along the direction of the electric field, thus forming a small conductive bridge between the two poles, even if it contains a small amount of water, this conductivity is small. The bridge will also be generated immediately, connecting the two poles, causing the breakdown voltage to drop sharply. For example, the water in the new oil will reach a saturated state within the range of 0.01%, but with such a small amount of water, the breakdown voltage of the oil can be dropped. Very low, in addition to water, oil often contains other stolen goods, so the relationship between water content and breakdown voltage cannot be expressed by a formula. In addition, the breakdown voltage depends not only on the water content, but also on the state of the water in the oil. For example, the same water content can lower the voltage to different degrees. Generally, water in an emulsified state has the greatest impact on breakdown voltage, followed by dissolved water.

　　2. The influence of temperature on the breakdown voltage depends on the presence or absence of impurities and moisture in the oil. The oil that does not contain impurities and is dried without moisture has little effect on the breakdown voltage under general temperature. This is because under a certain field strength and temperature, the oil molecules themselves are not easy to crack, that is, they are not easy to be ionized. But when the temperature rises to a certain level, the oil molecules themselves are ionized due to the cracking surface, and as the temperature rises, the oil The viscosity of the product is significantly reduced, and the electrons and ions generated by ionization will move faster due to the reduced force, resulting in the breakdown of the product and a significant drop in breakdown voltage.

　　Improve the breakdown voltage performance of the transformer oil to ensure the normal use of the oil. The two-stage transformer oil vacuum oil filter produced by our company adopts the principle of vacuum dehydration and separation to quickly and effectively remove impurities inside to ensure that the oil is pure. The following is a comparison chart of the decolorization effect of our company's on-site transformer oil vacuum oil filter.
