  • Working Life of Transformer Oil Puriifer
    As large nuclear power plants, power plants, transformers run for a long time without interruption, even a few years before a downtime maintenance. So Transformer Oil Filtration Machine also stop for a long time without working. Generally, it is not used for several months. In this condition, we should care following aspects during the operation of Transformer Oil Purifier First: Shut down the order, first turn off the heater (remember this must be the first off), if not the first heater, may lead to empty, may cause the machine burned, or even cause serious Leakage and other dangerous accidents. Second, after closing the heater, we need to keep the vacuum pump and the oil pump running, until the oil cools to 50 degrees below the time in the next step, because if the high oil temperature in the case of downtime, high temperature oil may be sealed Have an adverse effect. And then turn off the vacuum pump, and the oil pump, while opening the vacuum tank on the release valve to remove the vacuum, due to low internal pressure may not be able to rule out the oil inside the machine. In the exclusion of oil tank when we can take a reasonable use of the pump and the ball valve opening and closing, the effective elimination of the remaining oil inside the machine. At the same time we need to pay attention to is that if it is not suitable for a long time machine, this time we must be completely inside the machine to remove the remaining oil clean. Once again boot the next time to successfully boot, and will not pollute the nature of the oil when running again. Second: Maintenance of Transformer Oil Filtration Machine during stop 1. After prolonged use, we need to pay attention to check the electrical equipment and lines are burning black phenomenon, if found to promptly remove the problem. 2. After long-term use, we must regularly replace the vacuum pump in the vacuum pump oil. 3. Regular or long time before you must use the filter must be cleaned to prevent impurities hardening coke plug filter. 3. Each time the condensate condensed water is removed to prevent water from corroding the body. Above aspects are precautions of shutdown of Transformer Oil Purifier. We must pay attention to the daily maintenance, which are important for improve the working life of Transformer Oil Filtration Machine. http://www.acorefiltration.com/blog/how-to-improve-the-life-of-transformer-oil-filtration-machine_b11

  • Measurement Standard Of Transformer Oil Tester
    We developed transformer oil tester according to the standards of IEC156 and ASTM. The following tests we recommended for a complete analysis of transformer oil: The dielectric breakdown is an indication of the oil`s ability to withstand electrical stress. The most commonly performed test is ASTM D-877, and because of this, it is more readily used as a benchmark value when comparing different results. The oil sample is placed in a test cup and an AC voltage is impressed on it. The electrodes are two discs, exactly 1 in. in diameter and placed 0.10 in. apart. The voltage is raised at a constant rate, until an arc jumps through the oil between the two electrodes. The voltage at which the arc occurs is considered the dielectric strength of the oil. For systems over 230 kV, this test is performed using spherical electrodes spaced 0.04 or 0.08 in. apart (ASTM D-1816). Portable equipment is available for performing both levels of this test in the DST automatic transformer oil tester is developed especially for measurement of insulating oil's breakdown voltage, it is unique in the market due to its functionality and the excellent user benefit in comparison to costs. The DST transformer oil tester provides delivers clear and reliable measurement results. It is no longer necessary to send samples to the laboratory. Environmental and transport influence on the samples are minimized. Due to its design, the tester is particularly handy, easy to operate and especially excellent to use under tough ambient conditions. By proper programming, DST transformer oil tester has got functions of auto boosting, step down, stirring, display and print out.

  • Functions of Transformer Oil Purifier
    Transformer insulating oil must be purified by transformer oil purifier, as the influence of heat and electric field, the transformer oil in contact with oxygen is gradually oxidized to various oxides, alcohols, aldehyde, acid etc, and form insoluble gum and sludge precipitation. These various oxides reduce the insulation performance of the transformer insulating oil, Water and gas in transformer oil has two forms: dissolved water and gas (saturation point) are in electric systems. And free water and gas (above the saturation point) are in insulating oil. Because the system leakage, untight seal, long-term heat load, open storage etc, water and impurities in the air will dissolved in oil. Untreated transformer oil contains 50 to 60ppm water and 10% to 20% air, in order to reach requirement, it must remove water, gas and impurities under state of rated vacuum and temperature. So the oil during use should be regularly purified by vacuum transformer oil purifier. Dielectric properties of transformer oil mainly depends on water, gas and impurities content. Even new oil storage and transportation will inhale the gas and water, so new oil should be purified by transformer oil purification plant before using.

  • Choosing A Right Transformer Oil Purifier
    High Voltage Transformer oil is suitable for 500KV super HV transformer, it can also as insulation and cooling medium in electric power equipments. When we test transformer oil, SH 0040-91 used in the detection of oil industry standards. Test project for the appearance, color, density (20 degrees Celsius), kinematic viscosity and aniline point, freezing point, pour point, flash point, neutralization value, water soluble acids or alkalis, corrosive sulfur, oxidation stability (precipitation, acid), breakdown voltage and dielectric loss factor (90 degrees), Interfacial tension, trace moisture, gassing, dispersion, and so on. Particular attentions are: 1. While observing the appearance of oil, oil injection should be 100ML in the graduated cylinder, at 20 ℃ ± 5 ℃ environment Visual, If you look the results disputed, as specified by the GB/T 511 standards for determination of oil content of mechanical impurities. 2. .Oxidation stability, gassing to super high voltage transformer oil project, you should testing at least once a year. 3. When Determination of EHV transformer oil Breakdown voltage and determining the pour point and freezing point, you can use qualitative filter paper filtration.. In the process of oil use, If there is a detection target does not meet SH 0040-91 industry-standard requirements, you should replace with new oil in time, or use a private transformer oil filtration machine to purify the super HV transformer oil.

  • The Difference of Transformer Oil Purification Machine
    In the market, there are many transformer oil purification machine, If the user need a good machine, they should know the difference of them. The transformer oil purification machine has double stages vacuum structure and single stage vacuum structure. Following is introduce of two model, we hope there information can help user choose a better one. Single stage vacuum transformer oil purification machine only equips one vacuum pump and one vacuum vessel. Double stages vacuum transformer oil purification machine from different factory also have difference. Firstly, as the double stage vacuum machine is specially used for high voltage transformers, so one vacuum pump is not enough, because the ultimate vacuum value usually -0.095MPa, it is not enough for removing the trace water and gas from oil, so we need use roots vacuum pump to improve the vacuum pressure, and make ultimate vacuum value can reach -0.099MPa, Secondly, Double stages type also means the double vacuum separators, transformer oil flows through two vacuum separators, it will do two times of dehydration and degasification processing, so it can remove gas and water more completely than one vacuum separator.

  • Vacuum Transformer Oil Filtration Machine
    If the transformer oil isn`t degassed before injection transformer, when the transformer put into operation, since the internal temperature and pressure changes of the transformer body, the gas dissolved in the transformer oil is gradually released, or the surface of the solid transformer oil bubbles will appear, because of the dielectric constant of the bubbles is much larger than the transformer oil, which breakdown voltage below the breakdown voltage of the insulating oil, the bubbles easier partial discharge occurs in the operation, frequent discharge will continue to damage the transformer insulation. If the dissolved gases in the transformer oil reaches a certain level, it will release large volumes of gas, these gases will not only make the operation of the Buchholz relay air bridge is formed, and may be provided along the direction of the electric field, causing the transformer internal breakdown, it is a serious threat for operation of the transformer. The gas contained in the transformer oil, and acetylene is a special gas, acetylene generate at 700 degrees. 2 or more under high energy discharge to generate, so become an important basis for determining transformer internal spark discharge or arcing fault, since the insulating the oil in the refining process produces acetylene gas, if don`t degass before inject the oil to transformer, it will seriously affect the discharge of transformer internal fault judgment. So we suggest use the vacuum transformer oil filtration machine to do degass process. Vacuum transformer oil filtration machine works under the vacuum status, it is a basic requirement for vacuum oil purification machine, if the working vacuum reach to -0.095MPa, this machine can satisfy the degass demand. If we use this kind machine to degass process for the insulating oil, the gas content will reduce or to zero. If the oil contains much gas, we can see it through the vacuum separator viewer, because the oil goes into the vacuum tank which is negative pressure, the gas will transgress under the press action. The transformer oil filtration machine can easy pump out those gas to air.

  • Working Principle Of Vacuum Oil Purifier
    Vacuum oil purifier is designed according to different boiling point of water and oil, it is composed of by primary filter, heating system, fine filter, condenser, vacuum tank, fine filter, water tank, vacuum pumps, oil drain pump and the electrical cabinet. Vacuum pump extract air in vacuum tank to form vacuum, the out-side oil by the role of atmospheric pressure, through the inlet pipe into the primary filter to remove large particles, and then into the heating tank. After heating such as 40 to 75 ° C, the oil get through the solenoid valve into vacuum tank, this valve can automatically control the amount balance of oil into and out of the vacuum tank. The heated oil becomes oil mist by sprayer into vacuum tank, the rapid evaporation of water in oil into steam and sucked into condenser by vacuum pump. Water vapor through the condenser back to the liquid water and discharge. The gas in oil is drain out rapidly by vacuum pump. After vacuum tank, the oil get through fine filter to separate the particulate impurities, then clean oil is discharged.
