Abstract

The invention provides a small-sized transformer. The small-sized transformer comprises an iron core, a winding, a framework, an upper bracket, a lower bracket, a wiring terminal and a protective cover, wherein the winding is wound on the framework, the framework sleeves and is used in cooperation with the iron core, the upper bracket is bent, covers the upper surface of the iron core, and is fixed with screws penetrating the upper bracket forward and backward, the wiring terminal is fixed to the upper bracket through screws on the top surface, wires drawn from the framework are connected to the wiring terminal located on the top, the upper surface of the wiring terminal is also covered with the protective cover, the lower bracket is fixed to the bottom of the iron core through screws, andfixing holes are formed in bending surfaces. The small-sized transformer has the advantages of simple structure, small size, low power consumption, easy heat dissipation and strong short-circuit resistance and is suitable for a wide range of applications.

Description

technical field [0001] The invention relates to the technical field of power transformers, in particular, the invention relates to a small transformer. Background technique [0002] Transformer is a kind of static electrical equipment, which is designed and manufactured according to the electromagnetic principle. The main components include iron core, winding, insulation, shell and necessary components. Due to the difference in capacity and voltage, the structure of the transformer's core, winding, insulation, casing and necessary components can be different. At present, the existing transformer manufacturing technology is quite mature, but there are still problems such as complex structure, poor heat dissipation, bulky volume, excessive internal friction, and poor insulation. Contents of the invention [0003] The primary purpose of the present invention is to solve at least one of the above-mentioned technical defects, especially the technical defects of poor heat dissi...
