If it is a substation equipment transformer, first remove the anchor screws on the edge of the box cover, and then put the machine and equipment on the cover according to the outer cover slot plate to hang on the machine itself, remove the high-voltage and low-voltage flexible waterproof casing and extraction parts, and then remove the power transmission Only part of the machine equipment itself can be obtained. If you want to disassemble further, disassemble the iron core clamp, disassemble the upper iron yoke, and then mention the split of the magnet coil.

1. Buy a bottle (approximately one liter) of banana water at an analytical chemistry store. Then you find a container and put the transformer in, but the container should be wired glass or porcelain as much as possible. The transformer should be placed in a certain depth, and then put the banana water in, called banana water without transformer. Cover the container with a wire glass back cover to prevent the banana water from evaporating. So invaded for twenty-four hours. On the second day, it can be seen that the three-proof paint on the transformer has long been loosened, so that the iron core of the transformer can be unplugged. When pulling out the iron core, try to pull a piece of the surface first, if one piece, the bottom is easy to remove. When removing other pieces, you can remove 2-3 pieces with a blade or smoothness, and only 2-3 pieces are needed each time. When disassembling, the first piece may be damaged, it doesn't matter, a transformer missing one or two pieces will not harm the transformer. Also note that both sides of the transformer should be disassembled. Then, clean the removed ferrite core with banana water to remove the remaining paint. In addition, the transformer structure can still be used at this time. In addition, the paint has become loose, and the silk-covered wire is disassembled, leaving the structure for use. Generally speaking, silk covered wire cannot be used at this time. Unless you wash all the paint on its surface, otherwise it will not be able to. Note: When making the transformer again, if the iron core is not enough and there is a gap between the iron core and the frame, it must be plugged tightly with thick cardboard to prevent magnetic vibration noise. Sometimes when you look at the full insertion, in fact, you can find the gap with the blade or the smoothness. I think it must be filled.

2. Heating: heating can be done in two ways, 1) 4-5mm stainless steel plate after the heat treatment furnace, the plan design drawing of the transformer core prevents immediate heating, which is common for low-requirement cattle such as electric cattle, such as choke coils, etc. method. 2) Boil immediately to keep the magnet coils boiled in oil. Diesel engine or low-mark oil can be used. Edible oil needs a safety factor! The second step is the first I on the important surface of EI, which can be easily cleaned. The third step is to take a piece of broken woodworking saw blade with a length of about 20mm, bring the first piece of the transformer close to the edge of a board, and hit the woodworking saw blade with a high-chromium alloy hammer to rush the first piece E. Take the second and third slices in turn. The power-consuming knife separates each piece until it is completely cleaned.
