Double-C combination transformer core structure

Abstract

The invention discloses a double-C combination transformer core structure, comprising two cores and a clamping frame. The clamping frame encloses the outer side of the cores. Each core is composed ofa plurality of silicon steel sheets; two ends of each core are provided with silicone steel sheets; the ends of each core are provided with connection holes inside; the inner surface wall of each connection hole is provided with vent channels at equal angles; the middle of the arc end of each core is provided with a slideway; the inner surface walls of the arc ends of the clamping frame are symmetrically provided with sliders. The double-C combination transformer core structure has the advantages that the structure is formed by stacking a plurality of C-shaped silicone steel sheets of corresponding structure; cooling channels and vent channels used with each other help ventilate and cool comprehensively the inside of the connection holes and the two sides of the cores, heat generated by the heat can be conducted and dissipated as soon as possible, the temperature of the core structure itself is decreased, and influence on normal use of a transformer due to excessively high temperatureof the cores after long-term operation is prevented.

Description

Technical field [0001] The invention relates to the technical field of transformer iron cores, in particular to a double-C combined transformer iron core structure. Background technique [0002] The iron core is the main magnetic circuit part of the transformer. It is usually made of hot-rolled or cold-rolled silicon steel sheets with a high silicon content and coated with insulating paint on the surface. The iron core and the coils wound on it form a complete electric In the magnetic induction system, the size of the power transmitted by the power transformer depends on the material and cross-sectional area of ​​the core. [0003] However, the existing transformer core structure lacks necessary measures for heat dissipation, and a large amount of heat will be generated after the core is operated for a long time. This heat cannot be quickly and quickly dissipated to the outside, causing the temperature of the core itself to rise. , Affecting the stable operation of the core. Summ...

Problems solved by technology

[0003] However, the existing transformer core structure lacks necessary measures for heat dissipation. After the core runs for a long time, a large amount of heat will be generated. These heat cannot be dissipated in a timely and rapid manner, resulting in the temperature rise of the core , affecting the operation stability of the iron core
