Winding device for coil winding in transformer

Abstract

The invention relates to a winding device for coil winding in a transformer, and relates to the technical field of electrical equipment. The winding device comprises a rack, a driving motor and a clamped end are arranged on the rack, and the driving motor is relative to the clamped end; a winding roll is arranged between the driving motor and the clamped end; the winding roll is provided with a rotation shaft; a air inflation layer and a spongy layer are sequentially nested on the rotation shaft from inside to out; one side of the rack is provided with an air cylinder; the air cylinder is provided with a piston rod pointing to the winding roll; the end portion of the piston rod is provided with a first magnetic thrust shoe; a ring baffle is arranged on the winding roll; one end, close to the first magnetic thrust shoe, of the ring baffle is provided with a cleaning solution steeping layer connected with the spongy layer; one side, close to the first magnetic thrust shoe, of the cleaning solution steeping layer is provided with a second magnetic thrust shoe; and repulsive force between the first magnetic thrust shoe and the second magnetic thrust shoe is gradually increased as distance approaches. By the design of the air inflation layer and the spongy layer, and tightness of a seizing guide line is adjusted to an appropriate degree.

Description

technical field [0001] The invention relates to a wire pay-off device used for coil winding in a transformer, belonging to the technical field of electric equipment. Background technique [0002] The transformer consists of an iron core and a coil. The coil has two or more windings. The winding connected to the power supply is called the primary coil, and the remaining windings are called the secondary coil. It can transform AC voltage, current and impedance. The simplest core transformer consists of a core made of soft magnetic material and two coils with unequal turns on the core. The function of the core is to strengthen the magnetic coupling between the two coils. In order to reduce the eddy current and hysteresis loss in the iron, the iron core is made of laminated painted silicon steel sheets; there is no electrical connection between the two coils, and the coil is wound by insulated copper wire. One coil connected to AC power is called the primary coil, and the othe...

Problems solved by technology

At present, during the winding process of most coils, the pay-off device will have a state where the wires are bundled too tightly or too loosely, so it is necessary to design a device that can ensure the tightness of the pay-off
