Perchè a macchina di bobinatura di fogli di trasformatore limita u spessore di fogli d'aluminiu? Cumu aumentà u gruixu di carta d'aluminiu?

Avvolgimentu di foil, foglia d'aluminiu per esse tensionata, per mantene una certa tensione, liscia, bobina di avvolgimentu piatta, u più grossu u fogliu d'aluminiu richiede una tensione più grande, a tensione massima di a bobina di bobina hè limitata, superà a tensione massima di a macchina hè periculosa, a tensione hè troppu chjuca bobina di avvolgimentu sciolta, ùn pò assicurà e esigenze di taglia. Dunque, 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, ecc., can be considered as a whole, rather than blindly adjust the thickness to design and calculate the winding characteristics of the transformer.

Q:

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?

A:

1. You’d better buy some soft aluminum foil. Aluminum foil is available in several hard and soft specifications. You can consult the aluminum foil supplier.
2. If 2.5mm foil must be used to wrap the machine nameplate, the thickness of aluminum foil on the machine nameplate is only allowed to be 2mm, and the machine’s super nameplate data will run, and the accident may not damage the machine itself. If you have a large number of platforms, it is recommended to add a set of compression aluminum foil devices under the winding die, while maximizing the tension of the machine, and then help the coil winding with the pressure of the coil roller.
3. I also encountered this problem. The thickness increased to 2.5mm and the width of aluminum foil increased beyond the allowable range of the foil winding machine.
