Winding coil based on rhombic dispensing soft composite material and transformer

Abstract

The invention discloses a winding coil based on a rhombic dispensing soft composite material and a transformer. The winding coil comprises a coil, insulating layers and two insulating terminals; the coil comprises multiple turns, and one insulating layer is arranged between each two turns of the multiple turns; each insulating layer is a piece of thick rhombic dispensing soft composite material; the two insulating terminals are separately positioned at two ends of the insulating coil; and the widths of the coil and the insulating layers are determined by the distance between the two insulatingterminals. The winding coil provided by the invention has the advantage that the rhombic dispensing soft composite material is high in electric strength, namely that the thick electric strength is not less than 6000V, and the requirement on interlayer electric strength can be met only through placing one piece of rhombic dispensing soft composite material, so that the security requirement of thecoil is met, the insulating thickness is also reduced, and thus the heat dissipation performance is improved, the service life of the transformer is further prolonged, and meanwhile, the manufacturingcost of the transformer is also reduced.

Description

technical field [0001] The invention relates to the field of transformers, and specifically discloses a winding coil and a transformer based on ribbed dispensing soft composite materials. Background technique [0002] The electromagnetic coils of modern low-voltage electrical appliances only need to choose high-strength enameled wires with stable quality, and strictly control the uniformity of the coil arrangement in the coil winding process, and control the pinhole degree, elasticity, and breakdown of the insulation layer of the electromagnetic wire itself. Performance indicators such as voltage and softening breakdown, generally rely on the insulation layer of enameled wire to meet the requirements of interlayer insulation, and there is no need to add interlayer insulation liners. However, due to the certain voltage gradient between the layers, and considering that the coil may be affected by some complex factors such as thermal stress, mechanical stress, electromagnetic f...
