How to disassemble waste transformers

If it is a distribution equipment transformer, first unpack the anchor bolts at the edge of the cover, then put the equipment itself on the cover according to the groove plate of the rear cover plate, remove the high-voltage and low-voltage waterproof casing and separated accessories, and then remove the conductor. Only a part of the equipment itself can be extracted. In case of further disassembly, disassemble the iron core clamp, disassemble the upper yoke, and then mention the disintegration of the electromagnetic coil.
The first way is to buy a bottle (about a liter) of banana water at an organic chemistry store. Then you find a vessel and put the transformer in, but the vessel must be laminated glass or enamel. The transformer should be placed in a certain deep layer, and then put banana water in. It is called banana water without transformer. Cover the vessel with laminated glass cover to avoid evaporation of banana water. So soak for 24 hours. The next day, it can be seen that the insulating paint on the transformer has already softened, so that the iron core of the transformer can be pulled out. When extracting the iron core, be sure to extract the top layer first. If it is one piece, the lower side is very easy to remove. When removing other parts, 2-3 parts can be removed with the cutter head or finish, and only 2-3 parts are required each time. When it is removed, the first one will be destroyed. It's all right. The lack of one or two transformers does no harm to the transformer. It should also be noted that both sides of the transformer should be removed. Finally, clean the removed ferrite core with banana water to remove the residual paint. In addition, the transformer frame can still be used at this time. In addition, the paint has softened, the wire wrapping has been removed, and the frame is reserved for application. Generally speaking, silk covered wire cannot be used at this time. Unless you wash all the paint on its surface, it won't work. Note: when making the transformer again, if the iron core is insufficient and there is a gap between the iron core and the frame, be sure to plug it with cardboard without loosening to avoid magnetic vibration noise. Sometimes when you look at the full insert, you will actually find the gap with the knife head or finish. I think it must be repaired.
The second way:
Step 1 heating: there are two methods for heating:
1. 4-5mm stainless steel plate behind the heating furnace, and the plan of transformer core to avoid immediate heating. For low specified buttons such as electric cattle, such as choke coil and other common methods.
2. Boil immediately so that the solenoid can be boiled in oil and diesel engine or low identification oil can be applied. Vegetable oil should be safe! The second step is the first I article on the top layer of EI key, which can be easily removed. The third step is to take a broken woodworking saw blade with a length of about 20mm, close the first blade of the transformer to the edge of a board, knock the woodworking saw blade with a hammer, and punch out the first e blade. Take the second and third pieces successively. Use a power knife to separate each piece until it is completely removed. More technical can also be carried out without heating. I dismantled thousands of transformers, and there is no shortage of 27 processing plants and other famous stores. Although the paint dipped very well, none of it broke easily.
