Transformers usually consist of an iron core, a coil, a casing, and necessary insulation materials. Transformer coils are generally divided into high voltage coils and low voltage coils. High voltage coils are usually wound with round insulated wires, and low voltage coils are usually wound with flat insulated wires or foils. Transformer coil winding is the central process of transformer manufacturing, which has a great impact on the performance of the transformer.
It not only directly determines the main economic and technical indicators such as the transformer's external dimensions, losses, and weight, but also directly affects the transformer's mechanical performance and absolute
Main quality indicators such as edge performance and heat resistance. The traditional winding of the transformer coil relies on human labor to entangle the insulated wire to the workpiece according to the consumption process, and the operator stops counting the resistance.
With the traditional winding method, not only the winding efficiency is low, but the quality of the waste coil is also poor. The current winding of transformer coils generally uses an automatic winding machine, which can significantly improve consumption efficiency and wiring accuracy. Among the automatic winding machines, there are vertical winding machines for winding large transformers, and horizontal winding machines and foil winding machines for winding lower voltage levels and smaller capacity transformers.
