Transformer vacuum oil treatment system

Transformer vacuum oil treatment system

Product introduction:

The transformer vacuum oil treatment system is a type of equipment specifically designed for processing the transformer oil, with the aim of removing the gases, humidity, and impurities from the oil, and enhancing the insulating performance and stability of the transformer oil.

Detection items:

Oil quality detection: Conducts detection on the physical and chemical properties of transformer oil, including density, viscosity, flash point, dielectric strength, acid value, moisture content, etc. These detection items can assess the insulating performance, stability, and pollution degree of the oil.
Gas analysis: Analyzes the gases in the transformer oil, including hydrogen, oxygen, nitrogen, carbon dioxide, carbon monoxide, etc. Gas analysis can determine the fault conditions in the transformer oil, such as discharge, corrosion, and assess the health status of the transformer.
Humidity detection: Detects the moisture content in the transformer oil, usually using a few thousandths of moisture content to assess the dryness degree of the oil. Humidity detection can determine the insulating performance and antioxidant ability of the transformer oil.
Solid impurity detection: Conducts detection on the solid impurities in the transformer oil, including particles, sediments, sludge, etc. Solid impurity detection can assess the cleanliness degree and filtering effect of the oil.
Oxidation stability detection: Detects the oxidation stability of the transformer oil and assesses the antioxidant performance and life prediction of the oil.
PCB detection: Conducts detection on the polychlorinated biphenyl (PCB) in the transformer oil to ensure that the PCB content in the oil meets the relevant standards and avoids causing harm to the environment and health.

Test object:

The test object of the transformer vacuum oil treatment system is transformer oil, also known as transformer insulating oil or insulating dielectric oil. Transformer oil is a kind of oil specifically used for insulation and cooling transformers, and it plays the roles of insulation, cooling, and arc extinction in the transformer.
The transformer vacuum oil treatment system mainly targets the processing and improvement of the transformer oil to enhance its insulating performance, stability, and service life. This system removes the gases, humidity, and solid impurities in the transformer oil, reduces the acid value and moisture content of the oil, and improves the physical and chemical properties of the oil, thus ensuring the normal operation and reliability of the transformer.
It should be noted that the test object of the transformer vacuum oil treatment system is the transformer oil itself, rather than the transformer equipment. Transformer equipment usually requires maintenance and repair, including the detection of insulating materials, the testing of insulation resistance, and the inspection of the winding, etc. These tasks are different from the test object of the transformer vacuum oil treatment system.

Technical parameters:
Processing capacity: The processing capacity of the transformer vacuum oil treatment system is usually measured by the amount of oil processed within a unit time, and the common processing capacity range varies from several liters/hour to several hundred liters/hour.
Working vacuum degree: The transformer vacuum oil treatment system needs to be processed under a certain vacuum degree to remove the gas and humidity in the oil. The common requirement for the working vacuum degree is 10 Pa to 1 Pa.
Oil temperature control range: The transformer vacuum oil treatment system usually has the function of oil temperature control to ensure that the oil temperature during the processing is within the appropriate range. The common oil temperature control range is 30 ℃ to 80 ℃.
Absolute filtering accuracy of oil quality: The transformer vacuum oil treatment system is usually equipped with a filtering device to remove the solid impurities in the oil. The absolute filtering accuracy of oil quality represents the size of the smallest particles that the system can filter out, and the common filtering accuracy is 1 micron to 5 microns.
Residual moisture content of oil quality: One of the goals of the transformer vacuum oil treatment system is to remove the moisture in the oil. The residual moisture content of oil quality represents the moisture content still present in the processed oil, and the common requirement for residual moisture content is below 10 ppm (one millionth).
Oil quality acid value: The acid value of transformer oil is an important indicator to assess the aging degree and stability of the oil. The transformer vacuum oil treatment system can usually reduce the acid value of the oil, and the common acid value requirement is below 0.03 mg KOH/g (kilogram potassium hydroxide per gram of oil).
