Abstract
The invention relates to a square and round iron core transformer. An iron core of the transformer is formed by coiling iron core materials, the cross sections of core posts of two phases A and C of a transformer iron core are in a D shape, and coils of the two phases A and C are also in a D shape. The transformer consisting of the iron core and the coils has the advantages that the short circuit resistance capability is greatly improved, the no-load loss of the transformer is effectively reduced, the cost is saved, the noise is reduced, and the work efficiency of the transformer is improved.
Description
Technical field:
The present invention relates to a kind of transformer, be specifically related to a kind of Wound iron-core transformer, especially a kind of transformer that has an area of iron core.
Background technology
Transformer extensive use city electric power, metallurgy, chemical industry; Along with China's rapid economy development; Demand to transformer is increasing, requires also increasingly highly, especially The Energy Conservation of Transformer and safety (mainly being the anti-short circuit capability of transformer) is had higher requirement especially.
Existing Wound iron-core transformer, cross section unshakable in one's determination and coil all is a rectangle, the external diameter linear portions of coil is longer, and when coiling, receives process technology limit, be difficult to take up, bad mechanical strength, thus cause anti-short circuit capability poor.
Fig. 1 is the structural representation of a kind of Wound iron-core transformer of three-phase three-column in the prior art.
The iron core of this transformer is made up of two identical inside casings 1 and a housing 2, and each iron core all is made up of two different frame posts.This cross section unshakable in one's determination is a rectangle.
The cross section of the coil 3 of this transformer is a rectangle also, and linear portions is longer, and anti-short circuit capability is very poor.
Summary of the invention:
The purpose of this invention is to provide a kind of circumference iron-core transformer.The A of this transformer core, C phase cross section are " D shape ", are multistage stairstepping cross section, have changed original Wound iron-core transformer iron core and have been the shortcoming of rectangular cross section.When making iron core; Being wound on outmost core material unshakable in one's determination is that smallest pieces is wide; That is to say that the longest core material width of girth is minimum; So reduce weight unshakable in one's determination, according to the test data statistics, adopting A, C is that the iron core weight of cross section has reduced about 3% for the iron core of " D " shape cross section than adopting with the rectangle mutually.Utilize the Wound iron-core transformer of this iron core manufacturing can effectively reduce the no-load loss of Wound iron-core transformer, practice thrift consumption, thereby improved the operating efficiency of transformer, reduce pollution environment to electric energy.This transformer coil A, C also are " D " shape mutually, the shortcoming that to have changed original Wound iron-core transformer coil be rectangle.Because transformer is bearing short circuit when test, the suffered impulsive force of coil is very big, and except axially partly stressed, the width of cloth also is very crucial concerning the coil of transformer to partly stressed.So the present invention has just solved this point.A, C be mutually the circular arc of " D " shape coil partly all in the outside, linear portions is adjacent with the B phase coil.Support with fixed head mutually and between the BC phase at AB, form the coil mutual restriction, when bearing short circuit, can effectively reduce of the influence of its impulsive force, prevent that coil is subjected to displacement, improve the anti-short circuit capability of transformer coil.
