The Main Function and Principle Of Transformer Oil Purifier
The Main Function Of Transformer Oil Purifier
Transformer oil oil purifier machine is a mechanical device that filters solid impurities and moisture in oil, improves oil quality and improves the insulation strength of transformer oil. It is a special equipment used in power plants, power stations, power companies, metallurgy, petrochemicals, railways and other industrial and mining enterprises to purify and treat unqualified electrical insulating oil. It can also be used for vacuum injection and extraction of insulated electrical equipment, and vacuum drying of moisture in electrical equipment.
Working Principle Of Transformer Oil Purifier
When the oil purifier machine is working, under the action of the internal and external pressure difference, the oil enters the primary filter through the inlet, and large impurities are filtered out. After the oil is heated by multi-stage infrared rays, it enters a special personalized vacuum separator. It first forms a mist and then a thin film, which expands its contact area in the vacuum to hundreds of times. The moisture in the oil is exposed to high heat and high vacuum. , quickly vaporizes under the conditions of large surface area and high pumping speed, and is discharged by the vacuum system;
The water vapor discharged from the upper part of the vacuum separator is first cooled and dehumidified by the condenser, and then cooled again in the cooler. The condensed water is discharged into the reservoir. The gas after two condensations and dehumidification is finally discharged into the atmosphere by the vacuum pump;
The dry oil after vacuum evaporation and dehydration in the vacuum separator is raised from negative pressure to positive pressure by the oil transfer pump, and the filtered clean oil is discharged from the oil outlet, completing the entire oil purification process.
It can be used for on-site oil filtration and oil replenishment such as various oil-filled transformers, oil-filled current and voltage transformers, and low-oil and high-voltage circuit breakers.
It can be used for hot oil circulation drying on site for the above equipment.
It can be used for vacuum oil injection and oil replenishment on site for sealing oil-soaked equipment and vacuuming equipment.
It can also be used for the regeneration and purification of slightly deteriorated transformer oil.
The transformer oil purifier can be called a machine that is versatile. Considering the problem of traditional oil pollution, the original oil-containing device is used as an oil tank to circulate the hot oil between the devices.
Why Transformer Oil Purifier Is Necessary
The largest reveal of fill up bearing transformer operated around the globe are filled together with liquid: called the transformer insulating oil. Typically the transformer oil used in many transformers is actually a type of petroleum-based hydrocarbon which is used for the high breakdown voltage in addition to chemical steadiness.
Transformers inside power supply and transportation have to perform reliably and since efficient as you possibly can for many years to be able to recoup advantages upfront fees. For a very long and successful lifetime of the exact transformer, the standard of the transformer oil has a key function. The quality of the very mineral oils and other dielectric fluids diminishes during functioning due to degeneration of the drinks.
Transformer oil damage due to water and oxidation
Damage is mainly as a result of contamination, overheating, electrical anxiety, and oxidation. There are a couple of main components occurring inside transformer essential oil during surgery which cause destruction.
The most common device causing wear and tear is moisture content contamination. Humidity, and hence waters, is present during the transformer necessary oil as little droplets (emulsion) or free of charge water in the bottom (demulsified water). Demulsified mineral water contamination is usually easily managed by removing it by way of filtration or perhaps centrifugal remedy. The removal of emulsified water demands vacuum lacks.
The emulsified and even demulsified kind of water have got profound outcomes on the preventive properties with the transformer olive oil as they may help dielectric energy of the water. Some of the contained water furthermore gets soaked up over time from the paper insulating material of the transformer which poorly affects the main insulation’s qualities. This standard water content on the paper warmth is especially hard to remove. Getting rid of the seepage requires drying with warmth and machine.
The next, less frequent deterioration takes place because of oxidation. This type of transformer oil decline is sluggish than that will caused by fluid alone, nevertheless effects is often more serious.
Oxidation results in gastric acids in the transformer oil and also increased creation of sludge. The oxidation speed very depends on heat. Transformers managed in hot temperature climates, consequently, are especially prone to this type of oxidation.
Operation Steps Of Transformer Oil Purifier
The operation steps of the transformer oil filter mainly include the following key steps
Preparation: Make sure all equipment (such as vacuum oil filter, precision oil filter, vacuum pump, etc.) and accessories (such as oil drums, oil pipes, valves, etc.) are ready and keep them clean and free of debris. Connect the inlet and outlet oil pipelines, connect the 380V power supply, and connect the safety ground wire. Check whether the loop connection is firm and whether the valves of each oil circuit are open.
Start the equipment: First start the cooling water pump and check whether the water circulation is normal. Then start the vacuum pump to make the oil in the vacuum pump run normally. When the vacuum surface reaches the limit, open the oil inlet valve, start the oil drain pump switch, and start the normal oil drain filtration cycle.
Filtration process: During the filtration process, it may be necessary to turn on the heater switch to evaporate the water in the oil. Pay attention to the increase in vacuum degree and adjust the opening amount of the oil inlet valve to balance the inlet and outlet oil.
Monitoring and adjustment: Monitor the changes in the pressure gauge to ensure that the oil drain pressure is below 0.3MPa. Check whether there is oil leakage at the oil drain pump and pipe joints. If there is, drain it immediately and lock the overflow valve to ensure the normal operation of the equipment.
Complete the operation: When the oil circulation is normal, you can take samples from the sampling port for testing. After the work is completed, open the vent valve to make the vacuum reach normal atmospheric pressure. After the oil in the cylinder is drained, drain the remaining oil from the drain plug to prevent mixing with different types of oils during the next use.
Note: In winter, pay special attention to draining the water in the vacuum pump and water tank to prevent freezing. During the operation, the deformation of the transformer box should be closely observed. If there is any abnormality, the vacuum pump should be stopped immediately and reported to the relevant personnel.
How To Use The Transformer Oil Purifier
Operation Process
Preparation: Check whether the oil filter is in normal condition, check whether the power plug is leaking, check whether the oil filter box is clean, and prepare new oil filter paper and waste oil collection container.
Start operation: Insert the power plug into the socket, operate the touch screen control system, pump all the waste oil in the transformer oil pool into the oil filter box, and turn on the heating system.
Oil filter operation: Open the oil filter chamber cover on the upper part of the oil filter box, cover the oil filter paper on the oil filter net, and then cover the lid. At this time, start the vacuum pump and observe the oil filter pressure gauge. When the pressure difference reaches the specified value, the oil filter paper needs to be replaced. After the oil filter is completed, turn off the vacuum pump and extract the waste oil precipitated in the oil filter box.
Shutdown operation: Turn off the heating system and power supply, remove the oil filter paper and oil filter net in the oil filter for cleaning and maintenance.
Precautions
When operating the oil filter, wear protective equipment to ensure safety.
When operating the heating system, the specified temperature range should be strictly followed to avoid affecting the oil filtering effect and equipment life.
When replacing the oil filter paper, the oil filter pump should be turned off to avoid damage to the equipment due to excessive oil filter pressure difference.
When filtering the oil, pay attention to the direction and covering position of the oil filter paper to ensure the normal flow of the oil and avoid secondary pollution.
