[0003] The traditional compression device used in the vacuum drying process of the winding is a hydraulic device. Although the hydraulic device can exert a constant compression force on the winding, the structure of the hydraulic device is complex, bulky, expensive, and requires maintenance. The production cost of the transformer winding is reduced, and the clamping operation of the winding on the hydraulic equipment is very troublesome, time-consuming and laborious

Description
technical field [0001] The invention belongs to the technical field of transformer production, in particular to a transformer winding drying constant voltage device. Background technique [0002] During the vacuum drying process of transformer windings, a constant pressing force must be applied to the windings to improve the mechanical strength of the windings and the stability of the box size, enhance the short-circuit resistance of the windings, and avoid the use of windings after vacuum drying. Coil press presses the winding process to improve production efficiency. [0003] The traditional winding device used in the vacuum drying process is a hydraulic device. Although the hydraulic device can exert a constant pressing force on the winding, the structure of the hydraulic device is complex, bulky, expensive, and requires maintenance. The production cost of the transformer winding is increased, and the clamping operation of the winding on the hydraulic equipment is very t...
