Foil winding, aluminum foil to be tensioned, in order to maintain a certain tension, smooth, flat winding coil, the thicker the aluminum foil requires greater tension, the maximum tension of the coil winding machine is limited, exceeding the maximum tension of the machine is dangerous, the tension is too small winding coil loose, can not ensure the size requirements. Therefore, here is not to say that you want to increase the thickness of aluminum foil, because transformer designers for the thickness of aluminum foil, section, current density, temperature rise, etc., can be considered as a whole, rather than blindly adjust the thickness to design and calculate the winding characteristics of the transformer.
Thank you very much for your analysis and answer. The original foil winding machine for the thickness of the aluminum foil is 2. Only 0, but if necessary, must be increased to 2.5. What is the easiest way to modify the foil winding machine?
