Winding machine manufacturers introduce the characteristics of the automatic transformer winding machine

The transformer is generally composed of core, coil, shell and necessary insulation materials. Transformer coils are generally divided into high-voltage coils and low-voltage coils, high-voltage coils generally use round insulated wire winding, low-voltage coils generally make the stomach with flat insulated wire or foil winding. Transformer coil winding is the central process of transformer production, the function of the transformer has a great impact. It not only directly choose the transformer size, loss and weight and other primary economic and technical indicators, but also directly affect the mechanical function of the transformer, insulation function and heat-resistant function and other primary quality indicators. Traditional transformer coil winding is relying on human power to insulate the wire in accordance with the requirements of the consumption process winding to the workpiece, and by the operation of workers to stop counting the number of resistance. With the traditional winding method, not only is the winding power low, but the quality of the scrap coils is also poor. Now the transformer coil winding throughout the use of active winding machine, it can significantly improve the consumption power and line accuracy. Among the active winding machines, there are vertical winding machines for large transformers, as well as horizontal winding machines and foil winding machines for transformers with lower voltage levels and smaller capacity.

Control features of active winding machine
①High power, no additional losses in the speed regulation process.
② wide application scale, can be used for cage type asynchronous motor.
③Large speed regulation scale, hard characteristics and high precision.
And the speed of three-phase asynchronous motor is chosen by the point frequency, the number of pole pairs of the motor and the rate of rotation. The torque of the asynchronous motor is the effect between the flux of the motor and the current flowing in the rotor, at a fixed frequency, assuming that the voltage is certain and only decreases the frequency, then the flux is too large and the magnetic circuit is full, which will burn the motor in serious cases. Therefore, the frequency and voltage should be changed in proportion, that is, the frequency is changed while the inverter output voltage is manipulated, so that the flux of the motor will be maintained to prevent the occurrence of weak magnetism and magnetic fullness. Because the general inverter generally choose V/f control, that is, variable voltage frequency method speed control, change the frequency and voltage to make the Z best motor control method.
