Process guarantee of liquid-immersed transformer

The liquid-immersed transformer winding process to wind the high-voltage coil is wound using a high-speed winding machine, which uses mechanical tension on the wire with constant tension. The liquid-immersed transformer system is to realize the automatic control of the cable with staples gauge, the cable is tight and compact, and the automatic counting is accurate. Since the liquid-immersed transformer's high-voltage coils are tightened and pressed tightly during the winding process, the high-voltage coil's wires are reliable, the insulation between the liquid-immersed transformer end is rigidly connected and there is no compression margin. The same is true for low-voltage coils. Therefore, the axial height of the liquid-immersed transformer with the phase winding after winding can ensure the design size.

Causes of damage to Oil-immersed transformers

The oil-immersed transformer is widely used equipment for power transmission and transformation in the power grid. Its price is expensive and its reliability directly determines the normal operation of the power grid. The heating of the Oil-immersed transformer during operation is an important reason for the gradual aging of its insulation system. From the perspective of power equipment renewal, the increase in the service time of the transformer will greatly reduce the cost of funds. The winding coil and iron core are the heat sources, while the transformer’s excessive internal temperature leads to a loss of the service life of the transformer. The transformer oil-paper insulation system is most affected by temperature changes, and the transformer hot-spot temperature reaches above the limit value. The deterioration of the insulation paper may lead to the failure of the insulation system.
