Explosion-proof Outdoor Oil-Immersed Test Transformer (75kV/8kVA)

Product features:

Compared with ordinary oil-immersed test transformers, this product is equipped with an explosion-proof sealed shell that meets the national Ex d IIB T4 explosion-proof standard, which can effectively prevent internal electrical arcs from igniting external flammable gases. The corrosion-resistant aluminum alloy shell resists salt spray and acid corrosion, extending the service life in coastal and chemical plant environments. The natural oil immersion cooling system ensures stable performance during long-time testing without additional cooling equipment. It is equipped with a dedicated explosion-proof junction box, which can safely connect the power supply and test lines in flammable and explosive environments. The built-in overpressure protection device can automatically release excess gas in the oil tank to ensure the safety of the shell during testing. It is also equipped with a rain-proof and dust-proof cover, which can be used directly in outdoor open-air test sites.

Product specifications:

This transformer has a rated output voltage of 75kV and a rated capacity of 8kVA, suitable for high-voltage testing in flammable and explosive environments. It adopts natural oil immersion cooling mode, which ensures stable heat dissipation during 4-hour continuous testing. The insulation class reaches Class F, allowing a maximum operating temperature of 155℃. The net weight is 220kg, and it can be lifted by a standard forklift for transportation. The overall dimensions are 950mm × 600mm × 850mm, which can be placed in a standard explosion-proof tool cart for mobile testing. The single-phase cylindrical winding structure reduces winding loss and improves test accuracy. The protection grade of IP55 explosion-proof can resist dust and low-pressure water jets, meeting the safety requirements of flammable and explosive environments. The power input is compatible with standard 380V 50Hz single-phase power supplies, and the test accuracy reaches ±1.2% of full scale, meeting the safety testing requirements of special industrial scenarios. The built-in insulating oil volume is 15L, which can meet the needs of 100 consecutive tests.

Product application:

This product is mainly applicable to oil field production bases, coal mine ground facilities, chemical plants, gas transmission stations and offshore oil platforms. Typical application scenarios include dielectric strength testing of explosion-proof electrical equipment, underground mining power distribution cabinets, and oil field pipeline pressure sensors. It can also be used for routine safety testing of electrical equipment in flammable and explosive places, ensuring the safety of testing work in special industrial scenarios. It complies with national explosion-proof safety standards, and has passed the national explosion-proof product certification, ensuring the safety and reliability of testing work in flammable and explosive environments.
