Problems solved by technology

[0002] Today, the existing transformers use traditional foil coils. Due to the unreasonable winding of traditional foil coils, the electric field distribution of the transformer is not ideal, and its foil coils are difficult to use directly on power transformers with higher rated voltages.
In addition, the foil coil winding process in the prior art is complicated and the operation steps are cumbersome

Embodiment Construction

[0013] The present invention will be described in further detail below.

[0014] A method for winding a transformer foil coil, comprising the following steps:

[0015] (1) Select a suitable winding die according to the inner diameter of the coil, and hang it on the mandrel of the winding machine to clamp it;

[0016] (2) Take out the copper busbar drawn from the coil, at this time, sand the surface to be welded with sandpaper, and clean it; at the same time, cut the end of the copper foil, pull it out, and insert it into the welding machine gap of the winding machine. Then place the prepared inner-leading uranium busbar on top of the copper foil, and weld the copper foil and inner-leading copper busbar together;

[0017] (3) Pull back the copper foil, put the copper busbar of the lead wire in the coil into the winding mold groove, fix it, and then start winding the coil;

[0018] (4) Place the end insulation on both ends of the copper foil and wind it together with the coppe...

Abstract

The invention relates to the technical field of a transformer coil winding method, and specifically relates to a transformer foil type coil winding method. The winding method comprises the following steps of: (1) selecting a proper winding former according to the inner diameter of a coil, and suspending and clamping the winding former on a spindle of a winding machine; (2) taking out a copper busbar going out of the coil, flatly shearing the end part of a copper foil synchronously, pulling out the copper foil, inserting the copper foil into a welder crack of the winding machine, and welding a prepared internally led-out uranium busbar on the copper foil; and (3) pulling back the copper foil, fixing the internally led-out copper busbar of the coil in a winding former groove, and then winding the coil. According to the invention, the existing winding machine is used for directly winding the coil without new devices and tools, the short-circuit resistance is improved, and the stability of the winding to impact over-voltage is improved.

Description

technical field [0001] The invention relates to the technical field of transformer coil winding methods, in particular to a transformer foil coil winding method. Background technique [0002] Today, the existing transformers use traditional foil coils. Due to the unreasonable winding of traditional foil coils, the electric field distribution of the transformer is not ideal, and its foil coils are difficult to use directly on power transformers with higher rated voltages. . In addition, the foil coil winding process in the prior art is complicated and the operation steps are cumbersome. Contents of the invention [0003] The purpose of the present invention is to provide a transformer foil coil winding method with simple winding method, simple operation steps, improved short-circuit resistance and stability of the winding against impulse overvoltage. [0004] In order to solve the existing problems of the background technology, the present invention adopts the following t...
