Precautions on Stripping of Power Transformer Coil

1, the 100kva distribution transformer coil stripping prohibit blowing with a fan blowing body, to prevent the impact of frigidity quenching.
2, demolition of power transformer mold can not use dirty gloves to help form removal. Because the coil temperature is higher than 100 ℃, the winding has not been completely cured successfully, dirty contact coil easily left spots, affecting the appearance of the coil and found the end of the transformer coil has a long strip of non-curing phenomenon, do not touch, do not clear .
3, the panel fastening screw due to pouring material into the hard and difficult to remove after the invasion, not hard to remove, to prevent the screw fracture.
4, be sure to clean up all the material inside the copper mouth, to avoid affecting the transformer test, misdiagnosed as coil turns deviation, DC resistance unbalanced or broken head failure.
5, remove the single phase step voltage regulators die when not pull hard pull, at the same time to check the coil surface is defective. There are parts of the defect immediately check the corresponding parts of the outer mold and be dealt with to avoid the next re-emergence of a similar situation.
