Abstract
The invention discloses a three-phase transformer with coils arranged in the shape like the Chinese character 'pin'. The three-phase transformer is mainly composed of the coils (1), a core limb (2), an upper iron yoke (3), a lower iron yoke (3') and a tension bolt (4). The core limb (2) is sleeved with the coils (1) which are clamped between the upper iron yoke (3) and the lower iron yoke (3'), and the tension bolt (4) is used for tensioning the upper iron yoke (3) and the lower iron yoke (3') for fixation. The three-phase transformer is simple in structure, high in practicability, capable of achieving large scale production easily, convenient to assemble and disassemble and easy to repair and maintain. The three coils are in an equilateral triangle arrangement structure, three magnetic paths are the same in length and are the shortest, three-phases magnetic resistances are equal, losses are low, and the three-phase transformer can be widely applied to electric power transmission and transformation step-up or step-down systems.
Description
Technical field
The invention belongs to electric power system power transmission and transformation category, relate to a kind of transformer, specially refer to the three-phase transformer that a kind of line bag isosceles triangle is arranged.
Background technology
The energy consumption size of transformer operation and the iron core of transformer and the version of winding and technology are closely related.The defects such as the line bag employing planar structure arrangement due to traditional transformer, exists three-phase magnetic loop uneven, and local flux direction and silicon steel sheet magnetic conduction direction are inconsistent, have restricted the lifting of transformer efficiency level, are being difficult to breakthrough aspect power-saving technology lifting.Although, on market, also there is a kind of three-dimensional reel iron core transformer, in the problems referred to above, there is certain breakthrough, but due to its core structure, its transformer wire bag cannot be produced separately, from technique, has restricted large-scale production, increased production cost, secondly, be in operation and occur that line bag can not detachable maintaining after damaging, thereby restricted popularizing of product.The invention provides the three-phase transformer that a kind of line bag isosceles triangle is arranged, the arrangement architecture of its three line bags is equilateral triangle, and three lengths of magnetic path are consistent; and all the shortest, three-phase magnetic resistance is equal, and loss is low; and manufacture craft is easy, is easy to large-scale production, the easy maintenance maintenance of easy accessibility.
Summary of the invention
The three-phase transformer that a kind of line bag of the present invention isosceles triangle is arranged, is mainly comprised of line bag (1), iron core column (2), upper yoke (3), lower yoke (3 ') and tightening bolt (4); It is upper that line bag (1) is sleeved on iron core column (2), is installed between upper yoke (3) and lower yoke (3 '), with tightening bolt (4) tension upper yoke (3) and lower yoke (3 '), is fixed.Iron core column (2) becomes column structure with permeability magnetic material closed assembly, and it is coniform that two ends become; Upper yoke (3) is identical with lower yoke (3 ') shape, upper and lower symmetrical installation, adopt permeability magnetic material closed assembly fixed-type, flat shape is Triangular Flos Mume shape, bolt hole (7) is established in centre, iron core column hole (6) is set on three plum blossom lobes, and iron core column hole (6) central point line is equilateral triangle, and iron core column hole (6) become coniform; Tightening bolt (4) adopts permeability magnetic material machine work moulding, is stud, and is equipped with nut.
The three-phase transformer that a kind of line bag of the present invention isosceles triangle is arranged, it is simple in structure, and Practical Performance is high, is easy to large-scale production, and the easy maintenance maintenance of easy accessibility, the arrangement architecture of three line bags is equilateral triangle, and three lengths of magnetic path are consistent, and all the shortest, three-phase magnetic resistance is equal, and loss is low; Can extensively send out and be applied to boosting or depressurizing system of electric power power transmission and transformation.
