Principle of transformer oil filtration system in power transmission and transformation project
Oil filter is a kind of filter unit which uses pressure filtration or vacuum evaporation pressure filtration method to remove solid impurities and moisture in impure oil. The oil filter is mainly used to improve the insulation performance of electrical oil and the purity of lubricating oil. Oil filter is divided into ordinary oil filter and vacuum oil filter. The effective oil filter is mainly used for purification and regeneration of turbine oil and lubricating machinery oil in power plants, power stations, industrial and mining enterprises.
The transformer oil machine is especially suitable for the purification of turbine oil, hydraulic oil, anti-wear oil, bearing oil and high viscosity lubricating oil with serious water or turbidity emulsification. It can effectively remove the moisture and impurities in the oil at high speed and make the turbid oil clear.
High voltage and ultra-high voltage transmission lines, substations, power switches, etc. are the core of power transmission and transformation engineering. In the transmission and transformation circuit system, transformer oil and power switch oil are widely used oil products, which play an important role in the whole transmission and transformation project and guarantee the safe operation and maintenance of the transmission and transformation system. Therefore, from the point of view of energy saving and consumption reduction and protection of transmission and transformation system and its facilities, transformer oil and power switch oil are widely used Oil filtration system is very necessary.
Transformer oil system is widely used in power transmission and transformation engineering, which is expensive, troublesome and dangerous to add. Therefore, a set of filtration system which can complete online oil pumping filtration, detection, oil injection and maintenance of transformer oil becomes a good helper of transmission and transformation system. The transformer oil filtration system is generally a vacuum filtration system as the core. After the transformer oil is detected to be contaminated, under vacuum negative pressure, the contaminated transformer oil is pumped into the filtration system for dehydration, impurity filtration and high-efficiency demulsification purification and reduction. Then, whether the filtered oil is qualified is tested. If it is qualified, the filtered clean transformer oil will be injected into the transformer; because it is not on-line, the transformer oil will be filtered The continuous operation of shutdown, so the filter system has been testing, pumping, filtering, detection, injection, forming an online cycle, completely unattended, safe and efficient.
