Description
Technical field
The utility model relates to field transformer, refers to that a kind of low pressure of dry-type transformer builds coil especially.
Background technology
Transformer utilizes electromagnetic induction principle a kind of voltage and current of grade to be converted to the voltage and current of another kind of grade of same frequency and the equipment of electric energy transmitting, the circuit part of the coil constitution equipment of transformer itself, it is directly connected with outside electrical network, be most important parts in transformer, be therefore called as " heart " of transformer.
Existing transformer coil has following defect: 1. because circular configuration volume is larger, spent copper material is many, the space occupied is also large, and because coil is enclosed within core limb, the excessive core volume that also causes of the volume of coil is excessive, not only limit cost and is not easy to transport, installation; 2. the stay in air channel is all be mixed between inside and outside two-layer coil, and this can not get enough guarantees with regard to making the steadiness of stay.
Summary of the invention
The purpose of this utility model builds coil with regard to the low pressure being to provide a kind of dry-type transformer, repacks circular coil in the past into ellipse, decreases material use amount, and the steadiness of the insulation property strengthened between coil and stay.
Technical problem of the present utility model is solved mainly through following technical proposals:
A kind of low pressure of dry-type transformer builds coil, comprise outer low-voltage coil, internal layer low-voltage coil, and by the air channel formed between outer low-voltage coil and internal layer low-voltage coil, described air channel and outer low-voltage coil, the junction of internal layer low-voltage coil is respectively equipped with air channel insulation, the many stays vertically arranged evenly are provided with in described air channel, the inner ring of described outer low-voltage coil outer ring and internal layer low-voltage coil is equipped with appearance insulation, this outer low-voltage coil and internal layer low-voltage coil two ends are provided with upper end insulation and lower end insulation respectively, wherein be provided with the upper collets of corresponding stay between two groups of upper end insulation, the lower collets of corresponding stay are provided with between two groups of lower end insulation, place is equipped with outer low-voltage coil directly over described upper collets and immediately below lower collets, internal layer low-voltage coil carries out the insulation pressing compressed.
Preferably, described stay is made up of glass fibre material, and middle, stay two ends is respectively equipped with projection, bottom described upper collets and lower collets top is respectively equipped with the groove of corresponding projection, all equal between described stay length, outer low-voltage coil height and internal layer low-voltage coil height three.
Preferably, described stay quantity is no less than the six roots of sensation, and the quantity between described stay, upper collets and lower collets three is all equal.
The beneficial effects of the utility model are: the utility model, by coil section is improved to ellipse, reduces cost and the volume of coil, also reduce cost and the volume of iron core simultaneously, reduce the production of product, transport and installation cost; Simultaneously Long Circle coil reduces than on the height of circular coil, saves transformer and takes up room, also making the height reduction of transformer station for during box-type substation; Insulation pressing also can not shelter from the outlet in air channel while fixed coil, and is further enhanced the steadiness of stay by the mode of being fixed at stay two ends; The utility model repacks circular coil in the past into ellipse, decreases material use amount, and the steadiness of the insulation property strengthened between coil and stay.
