Embodiment Construction
[0016] A production process for an ultramicrocrystalline cut iron core for split-type transformers, the key is: the steps of the production process include:
[0017] a. Put the ultra-microcrystalline strip iron core on the winding machine to wind it into an iron core, and spot weld it firmly;
[0018] b. Carry out heat treatment on the above-mentioned iron core. The heat treatment process adopts a staged heating method. First, the temperature is raised to 380°C, kept for 10-50 minutes, then raised to 450°C, kept for 10-50 minutes, then raised to 560-600°C, kept 30-60 minutes;
[0019] c. Use air cooling to rapidly cool down, so that the temperature of the iron core drops to 300°C, and it is controlled within 45 minutes from the end of the heat preservation to the temperature of the iron core falling below 300°C;
[0020] d. After reshaping the iron core, put it into the mold, put it into the prepared two-component epoxy resin paint together, and carry out vacuum impregnation ...
