The transformer winding machine is a special equipment used to wind the transformer coil. In the coil production process of the transformer, the winding equipment is divided according to the voltage level or capacity of the transformer, and the automatic winding of the high and low voltage coils of the winding distribution transformer is wound. Wire machine and foil coil winding machine; vertical winding machine and horizontal winding machine for winding large power transformer coils. Choosing the right transformer winding equipment is the key to producing high-performance transformers. According to different needs, transformer winding machines are divided into the following types. Automatic cable winding machine automatic cable winding machine is a winding distribution transformer. Special equipment for high voltage coils. The coil wound by the device is compact, small in size and high in strength. In order to further improve production efficiency, the new type of winding machine main engine speed is increased from 300rad/min to 500rad/min.
The cable arranging mechanism is increased from one head to two to three heads, that is, three coils can be wound at a time. At the same time, multi-wire (up to 4) is used and wound; the radial pressing mechanism is added; the tension is independently controlled for each pay-disel disc, so that the winding wires are arranged neatly, the turns are tightly uniform, and the current density distribution is uniform. At the same time, it is equipped with end insulation and unwinding mechanism and wire tensioning mechanism. The computer can set various parameters, which can complete the coil winding once, greatly improve the automation and reduce the labor intensity of workers.
Foil coil winding machine
The foil coil winding machine is a key device for winding low pressure foil coils. Tension control and foil strip rectification are key technologies for foil coil winding machines. The foil tension of the existing domestic or imported foil coil winding machine is generated by mechanical friction. The tension is not stable enough, which will result in uneven tightness of the wound coil. The DC resistance between the coils is inconsistent. Defects such as poor. A new type of digital foil winding machine has been developed in China. The machine uses a DC motor to produce foil strip tension. It is characterized by convenient, accurate and stable tension adjustment. The tension during the whole process is kept constant, thus ensuring the coil. Winding quality. In particular, the tension adjustment range is wide, and it is more suitable for winding a thin foil strip without causing damage to the end edge of the foil strip. Moreover, the tension motor is in a power generation state during the tension state, and the generated electric energy can be fed back to the winding motor or the power grid, and the friction energy consumption of the frictionless brake tension mode is remarkable, and the energy saving is remarkable. Moreover, the control system automatically calculates the diameter of the coil on the unwinder, so that the motor output torque can be adjusted at any time to ensure a constant tension throughout the winding process, which plays a key role in ensuring the coil quality. At the same time, the device biasing system adopts the photoelectric analog sensor non-contact detection foil edge, and the servo motor dynamically corrects the deviation. The system has high precision, fast response, high reliability and high precision of deviation. According to the available data, the equipment technology has been at the world's leading level. Vertical Winding Machine Transformer Winding Machine Transformer Winding Machine The larger the transformer capacity used now, the greater the impact on the power grid, and the higher the safety required. The quality of the transformer's manufacturing requires not only reliable electrical performance, but also mechanical stability and short-circuit resistance. The stability is mainly manifested in the manufacturing process control of the coil, that is, the electromagnetic balance of the high and low voltage coils is required, and the axial turns are tight and evenly distributed. Therefore, the coil winding process is required to be axially compressed, and the radial winding is required. The vertical winding machine uses the self-weight of the wire cake, the axial compression is natural, and the tension device is used to control the tension in the radial direction. Therefore, the winding of high-voltage coils in large transformers is now generally used in vertical winding machines. Even low-voltage spiral coils are produced by vertical winding machines.
