The structure of dry-type transformers is very complicated, and maintaining the characteristics and effects of dry-type transformers is also carried out by means of important parts of dry-type transformers, so it is important to understand the functions of important parts of dry-type transformers.

1. Winding (alias coil)

Generally, the insulated flat copper core wire or the round copper core wire is wound on the winding die. Chongqing dry-type transformer factory includes primary and secondary (high voltage, bottom voltage) 2 groups. The primary coil is to introduce the primary side electric energy into the dry-type transformer to complete the excitation regulator system process, and the other part fills the electric energy in the secondary coil. The secondary coil converts the magnetic energy into electric energy and transmits it.

Coils are generally connected in accordance with certain electrical equipment control loop connection methods (D angle connection or Y star connection). Giant Transformer.

2. Automobile fuel tank and base

The automobile oil tank is equipped with dry-type transformer oil for insulation and refrigeration. Chongqing Dry-type Transformer Factory is made of steel plate. It requires high impact toughness, small deformation, and no water leakage at electric welding. Our company adopts the corrugated sheet structure, which can not only satisfy the heat dissipation requirements of the dry-type transformer operation heat pipe, but also meet the requirements of the dry-type transformer oil rise and decrease, save the oil pillow, dry-type transformer oil and gas protection, greatly The air oxidation rate of oil is reduced, the application deadline and maintenance cycle time are increased, and the operating cost of dry-type transformers is greatly reduced.

3. Body insulation

Including primary insulation, locked rotor insulation and insulation with iron core, insulation with casing. Commonly used materials are: cardboard, epoxy resin glue, various insulating materials, dry-type transformer oil, electric welder's wood, etc. Among them, dry-type transformer oil not only has excellent insulation effect, but also has the actual effect of helping dry-type transformer heat pipe to dissipate heat, and is used for the iron core and coil of refrigeration operation.

The above are the important parts of dry change and its effect.
