Transformer dyeing machine is a special equipment used to wind transformer coils. In the winding process of transformer coils, we usually divide the winding equipment according to the voltage level or capacity of the transformer. There are winding high and low voltage coils of distribution transformers. Automatic wire winding machine and foil winding machine; there are vertical winding machine and horizontal winding machine for winding large power transformer coils. When using it, we need to debug it first. Different types of transformer winding machines have different adjustment methods. Shelves for winding machines and fixed spools. Winding molds and baffles corresponding to the product. Scissors, wrenches, needle-nose pliers, wooden hammers and other tools. Corresponding drawing documents. Double glass-fiber covered wire or enameled wire that meets the requirements of the drawing.
Frame board, insulating film paper, ventilation strip, white gauze tape, glass silk cloth tape, insulating tube, transparent adhesive tape. Prepare winding molds, wires, insulating film paper and ventilation strips as required by the drawings. Check the winding machine before use: whether the forward rotation, reverse rotation, etc. are normal. If you have any questions (especially the specifications of the line), you should promptly report to the person in charge of the production department and ask the production department to confirm. Install the mold, baffle plate, and frame plate separately, and tighten them with a wrench. Tightly wrap the outer frame of the frame with insulating film paper the same length as the mold for 3 times. Stick it with transparent adhesive tape so that it will not loosen. Pass the thread through the baffle and reserve the length of the thread as required.
Pass the insulated conduit that matches the wire gauge. The conduit must pass through the baffle, and ensure that it can be wound on the winding mold for more than half a circle to ensure that the conduit does not pass from Slide out of the coil. The length of the duct outside the baffle shall not be less than 60mm. The coils with taps should be tapped according to the order of the drawings, and the taps should be arranged in order, paying special attention to the accuracy of the number of turns; the guide tube guides the two wires of the tap together and directly leads to the root of the tap, leaving 60mm on the baffle The outer length of the tap line of the upper catheter is reserved as required. In order to ensure that there is no short circuit between the turns at the broken line at the end of the wire, two layers of glass cloth tape or polyester insulating film should be wrapped around the broken line.
If the drawing requires changing the wire gauge at the tap position, the large wire of the tap lead wire should be longer than the small wire, and note that the size of the wire gauge should be consistent with the drawing. If there are joints in the winding process, they are all externally connected within 8mm, and they are cut neatly at 80mm outside the baffle. Ventilation strips should be placed on the four corners of the coil. Place the ventilation strips, wind a few turns, and knock them on each four corners of the coil with a wooden hammer to prevent the ventilation strips from sliding, and then continue winding. When winding the secondary coil (coupling coil), first wind the primary wire. After the primary wire is wound, it is leveled and then wrapped with polyester insulating film for three and a half layers and the joints are glued with transparent tape. The pad is wound around the secondary line, so that the primary line and the secondary line are electrically isolated.
