Description

Double-wire parallel winding coil and reactor and transformer using same

Technical Field

The utility model relates to an electrical component field particularly, relates to a double-wire duplex winding coil and use reactor and transformer of this coil.

Background

The coils of the reactor and the transformer often encounter the condition of larger current or higher working frequency, and in order to reduce the coil loss, a double-wire parallel winding mode is usually adopted to improve the current-conducting capacity of the lead and the power-on sectional area of the lead.

The traditional double-wire parallel winding mostly adopts a mode that two leads are transversely placed side by side, as shown in figure 1, in the winding process, because the direction needs to be changed when each layer is wound to the end, manual operation is adopted, and the winding efficiency is low; in the actual winding process, the winding tension cannot be too large, so that the coil uniformity is inconsistent, and the unit consumption and the resistance deviation of the coil are large. And need artifical the patting coil among the coiling process, damage the enameled wire easily, serious can lead to the paint film damaged for the condition that the product burns out can appear when the circular telegram operation.
