Transformer live oil filter device

Abstract

The invention relates to a live oil filtering device for a transformer. The structure is that the oil outlet of the transformer oil tank is connected with the oil inlet of the deteriorated oil tank through the oil pipe, and the oil outlet of the deteriorated oil tank is connected with the oil inlet of the oil purification system through the oil pipe. The oil outlet of the system is connected to the oil inlet of the purified oil tank through the oil pipe, and the oil outlet of the purified oil tank is connected to the oil inlet of the transformer oil tank through the oil pump. The invention can realize alternate cycle and subsection optimization control of two systems of oil changing and oil filtering, can not only ensure the safety of online oil changing, but also improve the working efficiency of oil filtering. Ensure the insulation strength and service life of transformer oil, effectively improve the safety and reliability of transformer work, thereby reducing the number of power outage maintenance and prolonging the maintenance cycle.

Description

technical field [0001] The invention relates to an oil filter device, in particular to a live transformer oil filter device, which belongs to the field of electric power application. Background technique [0002] At present, oil purifiers account for about 60% of the oil treatment and oil purification equipment market. Various types of vacuum oil purifiers are common, but there are still many problems in terms of oil treatment effect. For example, vacuum filtration technology has disadvantages such as high noise, unsatisfactory vacuum degree, and low filtration precision, which leads to incomplete removal of moisture, gas and impurities. [0003] From the perspective of market demand, my country is a big country in the manufacture of mechanical and electrical products, and the market for oil purifiers has great potential for development. Now the oil purifier industry is facing product upgrades. For example, ordinary pressure plate and frame oil purifiers will become more eff...
