Embodiment Construction

[0015] The present invention will be further described through the embodiments below in conjunction with the accompanying drawings.

[0016] A method for determining the length of a transformer magnetic plate lamination, establishing a coordinate model, obtaining the formulas for each curve of the shape of the magnetic plate lamination, and then calculating the length of each magnetic plate lamination; comprising the following steps:

[0017] The shape of the magnetic plate laminate is composed of seven curves in sequence, which are curve one 1, curve two 2, curve three 3, curve four 4, curve five 5, curve six 6 and curve seven 7, of which curve one 1 and curve two 2. Curve four 4 and curve five 5 are circular arcs, O, O 2 , O 4 , O 5 It is the center of circle respectively; Curve three 3, curve six 6, curve seven 7 are straight line segments;

[0018] The arc curve 88 is the shape after the silicon steel sheets are stacked, and is a group of concentric arcs with the O poin...

Abstract

The invention relates to a determination method of lengths of laminating sheets of a magnetic pressing plate of a transformer and belongs to the technical field of transformer technology and manufacturing. The method comprises steps of establishing a coordinate model so as to obtain a curve formula of the shape of each laminating sheet of the magnetic pressing plate, thereby further calculating the length of each laminating sheet of the magnetic pressing plate; using the Excel to edit each formula, according to each curve formula, inputting a parameter and differentially inputting the radius of an arc curve eight (8) according to the length of each laminating sheet, thereby obtaining the length of each laminating sheet of the magnetic pressing plate. The beneficial effects are that the length of each laminating sheet of the magnetic pressing plate can be precisely determined, so shearing of the laminating sheets of the magnetic pressing plate can be performed based on this basis; smooth lamination of the magnetic pressing plate can be ensured; the method is simple; the size of each laminating sheet is precise; the lamination effects of the magnetic pressing plate is good; by applying the magnetic pressing plate on the transformer, a problem of the too big magnetic leakage flux is solved; product quality is ensured; the method is easy to promote and use; and production efficiency is improved.

Description

technical field [0001] The invention relates to a method for determining the length of laminated sheets of a magnetic pressure plate of a transformer, and belongs to the technical field of transformer manufacturing technology. Background technique [0002] At present, in order to solve the problem of large flux leakage at the end of the transformer, it is necessary to continuously improve the magnetic pressure plate, which is used at the upper and lower ends of the transformer coil. The magnetic pressure plate is a structure filled with silicon steel sheets in the insulating part, and each silicon steel sheet is non-linear. stepping. BACKGROUND OF THE INVENTION Since there is no method for determining the length of the transformer magnetic plate laminations, it is determined only by experience, resulting in the failure of the magnetic plate laminations to be cut, which affects product quality and cannot meet the needs of transformer production.
