S22-4000KVA变压器优点表现:

1. Reduce full load loss.

The five-grade silicon steel sheet joint with excellent performance is selected to improve the core structure and process and reduce the process index. Do not stack the yoke silicon steel sheet, do not use paint, and the cutting burr should be controlled below 0.02mm.

2. Reduce load loss.

Conductivity is improved by using a conductor pulled by an oxygen-free copper rod that is more conductive than electrolytic copper. Appropriately adjust the current intensity, improve the insulation structure, select semi-oil channels, prefabricated insulating materials, a full set of winding resistance, self-adhesive wires, and self-adhesive paper, reduce the insulation volume, improve the winding filling coefficient, reduce the winding specifications and reduce load loss

3. Reduce the loss of other components.

Improve the key structure: improve the structure, control the magnetic flux leakage of the windings during the design process, and adjust the ampere turn balance to reduce the impurity consumption of structural parts such as fuel tanks. Wave type fuel tank and pedestal radiator are selected to improve heat exhaust efficiency.

The S22-4000KVA transformer should use oil as the key insulation method of the transformer, and rely on oil as the cooling medium, such as oil immersion self-cooling, oil immersion air cooling, oil immersion water cooling and forced oil circulation. The main components of S22-4000KVA transformer are core, winding, oil tank, oil pillow, respirator, explosion-proof pipe (pressure release valve), radiator, insulating pipe, tap changer, gas relay, temperature gauge, oil purifier, etc.
