Oil purification process design of transformer oil filter
Transformer oil filter is widely used in power industry and large industrial and mining enterprises to purify insulating oil of power transmission and transformation equipment below 220kV, as well as hydraulic oil and lubricating oil purification treatment. It can remove moisture, gas and impurity particles in oil and improve the quality of oil Edge strength and oil quality ensure the safe operation of electrical equipment, and specific hot oil circulation drying, vacuum oil injection, vacuum pumping and other functions of electrical equipment.
Transformer oil filter is the third generation intelligent vacuum oil filter specially developed for insulating oil. It is used for purifying and filtering transformer oil, insulating oil, switching oil, capacitor oil, refrigeration oil and other electrical insulation oil. The purpose of transformer oil filter treatment is to eliminate the particles, moisture, gas and other pollutants in the oil, and reduce the acid value, so that the dielectric strength, gas content, acid value, dielectric loss and other key indicators of the oil meet the corresponding specification requirements, to ensure the safe operation of the user's electrical equipment.
Transformer oil filter is widely used in power supply, power generation, power transmission and transformation, power equipment manufacturing, power engineering, electrical equipment maintenance, electric power test, electrical scientific research, and other industries. It also has the functions of vacuum pumping, vacuum drying, online oil filtering, oil injection, hot oil circulation, etc., which can fully meet the various functional requirements of users on site. The transformer oil filter is an independent oil purification and filtration system with skid mounted structure, which can be used for on-line circulating filtration and can also be moved to the oil filtering point for off-line oil filtering.
In addition to reliable oil filtering function, the transformer oil filter can also be conveniently converted to separate oil pumping, oil injection, oil replenishment and functions to meet the requirements of on-site use. A new three-dimensional three-dimensional evaporation degassing and dehydration system and special vacuum are adopted Packing, increase the surface area of oil film, quickly separate water and gas in oil, high β value precision filter material, multi-stage filtration and step-by-step densification to remove fine particles in oil. The filter element has large volume and large pollution capacity. The transformer oil filter has long service life and is equipped with automatic detection function of filter element pollution degree.
High vacuum and large pumping speed of transformer oil filter can quickly remove water vapor in oil, greatly improve oil drying degree, breakdown voltage value and one-time filtration effect, shorten oil treatment period and improve oil performance. Low density indirect circulating carbon fiber heating technology is adopted in transformer oil filter system to prevent acetylene gas from oil cracking. Low energy consumption, uniform heating, stable oil temperature, the machine adopts automatic constant temperature control, automatic liquid level control, automatic defoaming control, automatic pressure protection and other excellent configuration, to ensure that the equipment will not spray oil in operation, safe and stable operation.
Transformer oil filter overload protection, overpressure alarm shutdown protection, overload protection, lack of oil protection, oil injection protection, phase sequence protection, etc. ensure the long-term reliable operation of the whole machine, humanized indication, automatic design, and oil temperature, pressure, vacuum degree, filter element pollution degree, operation status and other indicators. The oil purification process design of transformer oil filter can be processed on-line or off-line, with high degree of automation and unattended operation. It has the advantages of low noise, easy operation, long maintenance interval, low energy consumption, low operation cost and high oil filtering efficiency.
