Embodiment Construction

[0013] A three-dimensional triangular wound core transformer core winding mandrel according to the present invention, see figure 1 , the core mold includes a main body 1, on both sides of the main body 1 there are bar-shaped iron blocks 2 that can be separated from the main body 1, and the thickness of the bar-shaped iron blocks can be 15mm. A group of windows 3 are arranged at the joint between the inner side of the bar-shaped iron block 2 and the main body. A group of windows 3 are evenly arranged on the inner side of the bar-shaped iron block, and are used to bind the iron core column 6 through the steel binding band 5 . The upper and lower ends of the main body of the core mold adopt a slightly curved shape 4, so that the silicon steel sheet transitions well at the joints of each side of the core mold when the iron core is wound, and the winding is tight, eliminating the wave of the iron core column during winding, and improving the quality of the iron core. Greatly impro...

Abstract

The invention discloses an iron core winding core die for a transformer with a wound stereoscopic triangular iron core. The iron core winding core die comprises a body, iron bars separable from the body are arranged on two sides of the body, and a group of windows used for binding core limbs is arranged at the joint of the inner side of the iron bars and the body. The upper and lower end faces of the body are provided with radian. Iron chips wound by the core die are compact and non-wavy, and the iron core winding core die in combined structure facilitates binding and shaping of the core limbs after annealing, and iron core quality is greatly improved.

Description

technical field [0001] The invention relates to a transformer, in particular to a three-dimensional triangular wound core transformer core winding mandrel. Background technique [0002] As a new type of distribution transformer, the three-dimensional wound core transformer has become a trend of distribution transformers due to its double energy-saving advantages. As the core iron core of the three-dimensional wound core transformer, the manufacturing technology is the most complicated. In particular, the mandrel for core winding is immature, and the wound core cannot be used due to its high wave degree, resulting in rework or scrapping. Contents of the invention [0003] In order to overcome the problems existing in the prior art, the purpose of the present invention is to provide a three-dimensional triangular wound core transformer core winding mandrel, the iron chips wound by using this mandrel are compact, there is no wave, and its combined structure It is convenient...
