Dry-type transformer

Dry-type transformers are widely used in local lighting, high-rise buildings, airports, docks, CNC machinery and equipment, etc. Simply put, a dry-type transformer is a transformer in which the iron core and windings are not impregnated with insulating oil. It is a kind of transformer that does not use liquid cooling medium and adopts natural air cooling. Its windings are isolated by insulating materials, making the windings isolated from the external environment, thus avoiding the possible oil leakage, pollution and fire and other safety hazards in the oil-immersed transformer, but also reduces the workload of maintenance and repair.

The main advantages of dry-type transformer include:

1. safe and reliable: dry-type transformer does not use liquid cooling medium, avoiding the possible oil leakage, pollution and fire and other safety hazards of oil-immersed transformers, improving the reliability and safety of the equipment.

2. convenient maintenance: dry-type transformer does not need to carry out oil maintenance and replacement, maintenance and maintenance workload is smaller, can reduce the operating cost of equipment.

3. energy saving and environmental protection: dry-type transformer adopts air natural cooling, do not need to use cooling water or other cooling medium, has a high energy utilization rate and low environmental pollution.

4. strong adaptability: dry-type transformer is suitable for most environments and working conditions, can be in high altitude, high temperature, high humidity, harsh environments and other conditions of normal operation.

5. Long service life: the insulation structure of dry-type transformer adopts high temperature insulation material, which has excellent heat resistance and aging resistance, and can prolong the service life of the equipment.

Dry-type transformers are widely used in electric power, petrochemical, metallurgy, aerospace, high-speed rail and other fields, such as high-voltage power substations, power electronic equipment, electrical locomotives, aerospace power supply. In different applications, dry-type transformers have different specifications, structures and uses, and need to be selected according to specific needs.
