Abstract

The invention discloses an inner and outer winding coil layered heat dissipation apparatus. The layered heat dissipation apparatus comprises a rolling apparatus, an inner heat dissipation apparatus and an outer heat dissipation apparatus, wherein the rolling apparatus comprises an inner cylinder; four supporting parts are arranged on the outer surface of the inner cylinder and adopt T-shaped structures; the inner heat dissipation apparatus comprises a heat dissipation strip mechanism; the heat dissipation strip mechanism adopts a chain structure formed by mutually hinging a plurality of heat dissipation blocks one by one; the outer heat dissipation apparatus comprises an outer cylinder; a plurality of coamings are arranged in the outer cylinder; and an annular cooling bag is arranged between the coamings and the inner surface of the outer cylinder. Compared with the prior art, the inner and outer winding coil layered heat dissipation apparatus has a relatively wide gap structure, so that the creepage between high and low level voltage coils is avoided; a rolling movement can be continuously performed in a formed gap by utilizing the heat dissipation strip mechanism to continuously take away inner heat; and a cooling liquid is added in the annular cooling bag of the outer heat dissipation apparatus to form water circulation so as to continuously take away heat on an outer high-voltage coil.

Description

technical field [0001] The invention relates to a coil heat dissipation and cooling device, in particular to a layered heat dissipation device for inner and outer winding coils, belonging to the field of temperature control of electric equipment. Background technique [0002] All electromagnetic carriers of power transformers, such as iron cores, windings, leads and structural parts that can be linked by leakage magnetic fields, are heating elements. The heat generated by the heating element not only increases its own temperature, but also increases the temperature of the surrounding medium. Especially when the local temperature is too high, it may cause premature damage to the insulation, or cause the insulation medium to age at a high temperature for a long time. Gradually lose its insulating properties. As we all know, the life of the transformer is the life of the insulating material. When the transformer is required to have a certain life, the insulating material shoul...
