Combined transformer coil support system

Abstract

The invention belongs to the technical field of transformers, and aims to solve the problem of no axial heat dissipation channel inside the existing transformer cake coil, and specifically relates to a combined transformer coil support system, including a multi-layer support component for carrying the coil cake, a multi-layer The support assembly is connected by an axial connection assembly; the support assembly includes M combined spacer units radially arranged on each layer of coil cake; the combined spacer units arranged on adjacent coil cakes are arranged in a staggered manner; the combined spacer unit includes two slots Two grooved gaskets, two grooved gaskets are respectively arranged on the upper and lower sides of each layer of coil cake; one end of the grooved gasket is provided with a first opening slot opening inward, and a bracket assembly is arranged in the opening slot, and the bracket assembly is set There is a second open slot perpendicular to the first open slot, which opens inwardly, and is used to embed multi-turn windings; through the present invention, multiple axial heat dissipation channels can be provided in the coil cake, which simplifies the coil structure and enhances the coil strength at the same time , effectively improve the overall heat dissipation efficiency.

Description

technical field [0001] The invention belongs to the technical field of transformers, in particular to a combined transformer coil support system. Background technique [0002] Transformers are one of the most important power equipment supporting the power transmission network. With the continuous improvement of the power grid level, traditional transformers are facing more severe challenges; the problem of temperature rise has always restricted the direction of transformer miniaturization, low loss, and long life. The key factor of progress, and the coil is one of the most important heat sources inside the transformer, how to effectively dissipate heat from the coil is the key to solving the problem of temperature rise. [0003] For traditional pie coils, there are no axial heat dissipation channels in the individual pies. Usually, only axial heat dissipation channels are left at the inner and outer diameters of the coil pie, and the cooling medium is guided along the fixed ...
