In recent years, the domestic economy has developed rapidly and the demand for electricity has increased. Transformers are the basic equipment for power transmission and transformation in the power industry. They are widely used in substations, converter stations, and power plants. They are important in the power industry. status. Transformers are generally composed of iron core, coil, shell and necessary insulating materials. Transformer coils are generally divided into high voltage coils and low voltage coils. High voltage coils are generally wound with yarn winding machine round insulated wires, and low voltage coils are generally wound with flat insulated wires or foil materials.

DM0604 High Speed  Winding Machine

The core process of transformer manufacturing is coil winding, which is directly related to its performance. The technical level of coil winding largely depends on the technical level of the winding machine. Therefore, in order to manufacture high-level, high-performance transformers, it is particularly important to vigorously promote the development of special transformer equipment. Analyze the production process of the automatic transformer winding machine, design the overall scheme of the winding machine, and design the mechanical structure of the main winding machine, the tension adjustable pay-off stand, the automatic winding device, the main and auxiliary insulation layer supply and the driving device Analyze and establish the control system of the transformer automatic winding machine, including the Beckhoff control system, the three-axis servo system of the winding machine and the tension control servo system, and carry out the hardware selection and design and the design of the software part.


Design an automatic wire-arranging control system. According to the structure design of the coil, the geometry of the winding can be selected. The high-precision wire-arranging drive mechanism with AC servo system as the core operates. The winding spindle and wire-arranging mechanism are driven separately. The winding error caused by the change of the cable direction adopts the method of inertia error compensation, so that the coil turns are closely arranged. The particularity of the rectangular coil winding process is analyzed by simulation curve, and compared with the traditional wire tension control scheme, a wire tension control scheme with buffer compensation mechanism is designed, and the winding experiments under the two schemes are carried out respectively. The experimental results are compared and analyzed to verify whether the automatic wiring control system designed in this paper has good performance.


Modeling and analyzing the winding structure of rectangular transformers, establishing an insulation tape tension control system plan, analyzing the forces of each component in the system and establishing a mathematical model, designing a multi-input and single-output MISO insulation tape tension controller to achieve The stability of the winding tension control of the insulating tape, and the simulation analysis of the winding radius, winding angle and winding tension value in the Simulink system, and verifying whether the controller is reasonable according to the simulation results. In the actual transformer winding process, when adjusting the winding tension setting value at different winding speeds, it is verified whether the belt tension controller designed in this paper has good performance.
