Description

Transformer inner layer heat dissipation skeleton

Technical Field

The utility model relates to a technical field is made in transformer, transformer production, concretely relates to new inlayer heat dissipation skeleton of transformer.

Background

The transformer is a device for changing alternating voltage by using the principle of electromagnetic induction, and main components are a primary coil, a secondary coil and an iron core. The transformer framework is used for winding coils and fixing iron cores and is an indispensable main body part of the transformer. And the existing small-sized dry-type transformer winding framework is produced. The insulation material such as epoxy board is adopted to be processed and manufactured, and the following defects exist:

the support skeleton board that present wire winding used is whole panel, between transformer winding and iron core, but whole panel has leaded to the unable effectual release of the inside produced temperature of winding of transformer, leads to the bulk temperature rise of transformer, and then can't satisfy customer's demand.

Disclosure of Invention

For solving the not enough of prior art existence, the utility model provides a transformer inner layer heat dissipation skeleton.

The technical scheme of the utility model is that: the utility model provides a transformer inlayer heat dissipation skeleton, including skeleton board, wire winding arch and wire winding groove, the skeleton is the cuboid cavity section of thick bamboo that four skeleton boards spliced each other and formed, the skeleton board is the fretwork board of surface align to grid louvre, the skeleton board surface is provided with the wire winding groove of protruding and adjacent wire winding arch formation of wire winding.

Furthermore, the heat dissipation holes are one or more of round, rectangular, rhombic and trapezoidal.

Further, the framework is installed between the iron core and the winding.

Furthermore, the outer side of the iron core is fixed in the framework through a clamping piece.

The utility model discloses the beneficial effect who reaches does: this skeleton is installed between iron core and winding to improve on original skeleton board, make into the fretwork pattern when production man-hour, under the prerequisite that can guarantee product support intensity, as much as possible the fretwork part that appears, can increase the heat exchange of winding and heat dissipation wind channel department like this, further improve the radiating efficiency, reduce the temperature rise numerical value of product, and the surface of skeleton is provided with wire winding arch and wire winding groove, when manufacturing the transformer, accurate quick wire winding work that carries on has improved work efficiency.
