| 1. It is forbidden to blow the casting body with a fan when the coil of the power transformer is stripped to prevent the rapid cooling from affecting the fission. |
2. Do not use dirty gloves to remove the mold of the power transformer. Because the temperature of the coil is higher than 100 ¡ã C, the winding has not been completely cured. Dirt easily leaves spots after contacting the coil, which affects the appearance of the coil. It is found that the end of the transformer coil has a local elongated uncured phenomenon. .
3. The panel fastening screw is difficult to remove due to the solidification of the pouring material after intrusion, and cannot be disassembled hard to prevent the screw from breaking.
4. Be sure to clean all the materials inside the copper nozzle to avoid affecting the transformer test. Misdiagnosis is the deviation of coil turns, DC resistance imbalance or broken head failure.
5. When removing the outer mold of the power transformer, do not pull hard, and check whether the surface of the coil is defective. If there is a part defect, immediately check the corresponding part of the outer mold and deal with it to avoid similar situations next time.
