Problems solved by technology

If the insulating tube is directly wound on a square mold, it is difficult to make the cardboard and the mold fit well, and there will be gaps on each surface, which not only increases the size of the coil, but also in the coil winding process, due to the unevenness of the gap, It will cause deviation of copper foil and affect the quality and appearance of the coil

Embodiment Construction

[0017] Below in conjunction with accompanying drawing, further illustrate the present invention through embodiment.

[0018] In an embodiment, a manufacturing method of a square foil coil insulating paper tube includes the following process:

[0019] ①The paper tube is composed of a curtain oil passage 1 and several sheets of insulating cardboard 2. According to the insulation strength, the number and thickness of the cardboard can be increased or decreased; the cardboard is cut into the width required by the drawing, and the length of the cardboard is 5-8mm less than the circumference of the mold ; Bond the curtain oil passage well. Seen from the lead wire end, the first stay on the right side of the copper bar is closely bonded to the left edge of the cardboard, and the rest of the stays are glued in sequence according to the spacing of the curtain oil passage development diagram. OK, refer to attached figure 1 ;

[0020] ②Stack the curtain oil channel and the cardboard us...

Abstract

The invention relates to a preparation method of a quadrate foil type coil insulation paper roll, which belongs to the technical field of transformer coil production process. The technical scheme comprises the following process steps: (1) a paper panel is cut to meet requirements in a drawing for width, and curtain type oil groove is bond well; (2) the curtain type oil duct and the paper panel are laminated; (3) the bond paper panel and the curtain type oil duct are arranged on a mould; (4) a copper coil is wrapped by exerting slight tension or no tension; and (5) after a paper coil is completed by wrapping, the last support strip of the curtain type oil duct is just arranged on the upper part of the bond position of the paper panel. The invention has the advantages that the contact between the copper coil and the paper panel and between the mould and the paper panel is favorable by winding the copper coil to wind the paper panel and the curtain type oil duct on the mould along with the copper coil, the inner diameter of the coil is ensured, deflection of the copper coil because of the gap between the paper panel roll and the mould is reduced, the time for making the paper roll isomitted, working efficiency is increased, and thus, the aim that one stone kills two birds is achieved.

Description

technical field [0001] The invention relates to a manufacturing method of a square foil-type coil insulating paper tube, belonging to the technical field of transformer coil manufacturing technology. Background technique [0002] The structure of the square coil of the transformer usually needs to add an insulating paper tube to the inner diameter of the coil to increase the insulation distance between the coil and the core and the heat dissipation area of ​​the coil. If the insulating tube is directly wound on a square mold, it is difficult to make the cardboard and the mold fit well, and there will be gaps on each surface, which not only increases the size of the coil, but also in the coil winding process, due to the unevenness of the gap, It will cause deviation of copper foil and affect the quality and appearance of the coil. Contents of the invention [0003] The object of the present invention is to provide a manufacturing method of a square foil-type coil insulatin...
