Abstract
The utility model discloses an iron core pull plate of a transformer. An iron core pull plate body (1) made of steels is provided with a long hole (1.1) extending along the length direction. Low in cost, the iron core pull plate of the transformer enables to effectively block magnetic leakage routes and meanwhile significantly reduce the eddy current loss.
Description
Technical field
The utility model relates to the transformer technology field, specifically is a kind of iron core arm-tie of transformer.
Background technology
The arm-tie unshakable in one's determination of transformer generally is applied in the transformer of 10KV, is mainly used in the dry-type transformer, and its effect is fixed iron core by colligation, plays the important support effect when iron core closed assembly and lifting.There is following shortcoming in the iron core arm-tie of the transformer of prior art: because iron core is made up of silicon steel sheet, be easy to generate leakage field during the transformer conduction, in the iron core arm-tie, can produce eddy current loss, eddy current makes the iron core heating, consumed power is so the iron core arm-tie is generally the body of being made by non-magnetic stainless steel material, though can block the leakage field route like this, reduce eddy current loss, but the material cost height.
The utility model content
The technical problems to be solved in the utility model is, provides a kind of while can effectively block the leakage field route, reduces the iron core arm-tie of the low transformer of eddy current loss and cost greatly.
The technical solution of the utility model is, a kind of iron core arm-tie with transformer of following structure is provided, and its body is the iron core arm-tie body that is formed from steel, and described iron core arm-tie body is provided with the slotted hole that extends along its length.
The width centreline of described slotted hole overlaps with the width centreline of iron core arm-tie body.
The utility model compared with prior art, have the following advantages: because the specific position of iron core arm-tie in iron core, by the analysis of causes to generation eddy current loss, make iron core arm-tie body into common band steel by iron core, and described iron core arm-tie body is provided with the slotted hole that extends along its length, after two iron core arm-ties are fixing with iron core, can block the leakage field route effectively like this, greatly reduce eddy current loss and the material cost of iron core arm-tie body is reduced again.
As improvement, the width centreline of described slotted hole overlaps with the width centreline of iron core arm-tie body, can better block the leakage field route like this, is greatly reducing eddy current loss.
Description of drawings
Accompanying drawing is the structural representation of the iron core arm-tie of transformer of the present utility model.
As shown in the figure: 1, iron core arm-tie body, 1.1, slotted hole.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in the figure, the iron core arm-tie of transformer of the present utility model, its body are the iron core arm-tie body 1 that is formed from steel, and described iron core arm-tie body 1 is provided with the slotted hole 1.1 that extends along its length.Described iron core arm-tie body 1 also has a plurality of installing holes.
The width centreline of described slotted hole 1.1 overlaps with the width centreline of iron core arm-tie body 1.
Claims (2)
1. the iron core arm-tie of a transformer, it is characterized in that: its body is the iron core arm-tie body (1) that is formed from steel, described iron core arm-tie body (1) is provided with the slotted hole (1.1) that extends along its length.
2. according to the iron core arm-tie of the described transformer of claim 1, it is characterized in that: the width centreline of described slotted hole (1.1) overlaps with the width centreline of iron core arm-tie body (1).
