What equipment is needed to set up an oil chemical laboratory?

The important role of insulating oil in equipment operation mainly includes the following aspects:
‌Insulation effect‌: Insulating oil has excellent insulation properties and can significantly improve the insulation strength of electrical equipment. In high-voltage electrical equipment, insulating oil can fill the gaps in solid insulating materials to prevent air or moisture from entering, ensuring reliable insulation of the equipment. Especially in solid insulation such as transformers, cables, capacitors, etc., insulating oil can impregnate and protect these equipment, prevent moisture intrusion, fill the gaps in the solid insulation material, and strengthen the insulation of the equipment.
‌Cooling effect‌: During the operation of electrical equipment, such as transformers, motors, etc., a large amount of heat will be generated. If the heat is not dissipated in time, the equipment will overheat or even be damaged. The insulating oil absorbs heat through thermal conduction and convection, and dissipates the heat through the radiator to ensure the normal operation of the equipment. In an oil-immersed transformer, the insulating oil transfers the heat of the transformer to the oil tank and cooling device through the thermal circulation loop, and is then cooled by the surrounding air or cooling water.
‌Arc extinguishing effect‌: In electrical equipment such as circuit breakers, when an arc occurs, the insulating oil will thermally decompose and produce a large amount of hydrogen. Hydrogen has a large thermal conductivity and can absorb a large amount of heat, thereby quickly extinguishing the arc and ensuring the safety of the equipment and system. Safe operation. In addition, insulating oil can prevent the spread of arc and ensure the normal operation of equipment.
‌Anti-corrosion and maintenance effects‌: Insulating oil has maintenance and anti-corrosion effects on insulation materials. It can isolate the equipment insulation from contact with air, prevent oxidation and moisture, and ensure that the insulation strength is not reduced. Especially in equipment such as transformers and capacitors, insulating oil can fill the gaps in solid insulating materials to prevent moisture intrusion and extend the service life of the equipment.
In summary, insulating oil plays a vital role in the operation of equipment. It not only improves the insulation performance of the equipment, but also ensures the stable operation and safe use of the equipment through cooling and arc extinguishing.

Therefore, it is necessary to build an oil chemical laboratory

The equipment required by the transformer oil testing laboratory mainly includes the following categories:

‌Dielectric loss and volume resistivity tester‌: used to test the dielectric loss factor of transformer oil, reflecting the degree of aging of insulating oil during operation, and is one of the main control indicators for measuring the quality of insulating oil.

‌Acid value tester‌: fully automatic acid value tester is used to measure the acid value of insulating oil. The higher the acid content, the more serious the damage to the equipment.

‌Flash point tester‌: including fully automatic open flash point tester and fully automatic closed flash point tester, used to test the flash point of insulating oil, which is of great significance to the storage, transportation and use safety of oil products.

‌Trace moisture tester‌: used to measure the moisture content in insulating oil. Excessive moisture will affect the breakdown voltage of the oil and equipment corrosion.

‌Dielectric strength tester‌: also known as "oil bdv tester", used to test the dielectric strength of transformer oil to ensure that the electrical properties of the oil meet the requirements.

Interfacial tension tester: by measuring the interfacial tension of insulating oil, its quality can be judged. Good insulating oil usually has a high interfacial tension, which indicates that its intermolecular interaction is strong, the oil has a low degree of contamination and aging, and the insulation performance is more stable.

Water-soluble acid tester: Water-soluble acids promote the oxidation and deterioration of oil. By detecting water-soluble acids, the deterioration of oil can be detected and controlled in time to ensure the operation of equipment.

Particle size tester: Solid particles in insulating oil may cause premature wear of equipment, block filters, and even cause equipment failure. By using a particle size tester for regular testing, contaminants in the oil can be detected and treated in time to avoid potential equipment damage.

Chromatographic analyzer: Such as the PS-8001 transformer oil chromatograph, which is suitable for the determination of the content of dissolved gas components in the insulating oil of the power system, and can complete the full analysis of multiple gases in one injection.

These devices together constitute the core equipment of the transformer oil testing laboratory, ensuring comprehensive and accurate detection and analysis of transformer oil.
