Abstract

The utility model discloses a novel shell type electric furnace transformer which comprises an iron core (20), a low voltage winding (30), a high voltage winding (40) and a shell (50). The novel shell type electric furnace transformer is characterized in that the low voltage winding is in a coil structure in a manner that flat type copper wires are wrapped by paper and a plurality of flat type copper wires are wound in parallel and staggered together in a double helix mode; the low voltage winding is in a coordinated transposition mode; each phase is divided into four groups in parallel and is led out by using copper bars; every two winding leading copper bars in which currents are in opposite directions are arranged close to each other; an insulating layer (10) is inserted into the two winding leading copper bars; the high voltage winding, the low voltage winding and a voltage adjusting winding are staggered and wound into coils and sleeved into the iron core; and winding leading wires are connected with a binding post on the shell. The novel shell type electric furnace transformer has the beneficial effects that the transformer substantially has no eddy current and circulation current loss, so that the problem that the shell type electric furnace transformer has no complete and constant power output is solved.

Description

Novel Shell-Type Furnace Transformer

Technical field

The utility model relates to a kind of novel Shell-Type Furnace Transformer.

Background technology

Tradition Shell-Type Furnace Transformer secondary low-voltage winding adopt copper coin vertical around or the coiling of bare copper wire several paralleled conductor form, its drawback is, has eddy current loss, the full constant power output of limiting transformer also prolongs smelting time, thermal losses is larger.

The utility model content

The purpose of this utility model is exactly in order to address the above problem, and a kind of novel Shell-Type Furnace Transformer is provided.

To achieve these goals, the utility model adopts following technical scheme:

A kind of novel Shell-Type Furnace Transformer, has iron core (20), low pressure winding (30), high pressure winding (40), shell body (50), it is characterized in that, described low pressure winding is for adopting paper bag flat type copper wire double helix several paralleled conductor alternating expression loop construction, evenly coordinated transposition, whenever, divide mutually four groups and coupling copper bar to draw, winding is drawn per two mutually close arrangements of current opposite in direction in the copper bar, the middle insulating barrier (10) that inserts, the high pressure winding, low pressure winding and pressure regulation winding be staggered to be turned to coil and is inserted in the iron core, and each winding leading-out wire is connected on the binding post of shell.

The beneficial effects of the utility model are: this transformer does not have eddy current, circulation loss substantially, has solved the full problem of constant power output of Shell-Type Furnace Transformer.

Embodiment

For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.

As Figure 1-3, a kind of novel Shell-Type Furnace Transformer, has iron core 20, low pressure winding 30, high pressure winding 40, shell body 50, described low pressure winding 30 is for adopting paper bag flat type copper wire double helix several paralleled conductor alternating expression loop construction, evenly coordinated transposition, whenever, divide mutually four groups and coupling copper bar to draw, winding is drawn per two mutually close arrangements of current opposite in direction in the copper bar, the middle insulating barrier 10 that inserts, the high pressure winding, low pressure winding and pressure regulation winding be staggered to be turned to coil and is inserted in the iron core, install shell, each winding leading-out wire is connected on the binding post of shell again.

The above only is preferred implementation of the present utility model, and protection range of the present utility model is not limited in above-mentioned execution mode, and every technical scheme that belongs to the utility model principle all belongs to protection range of the present utility model.For a person skilled in the art, some improvement of under the prerequisite that does not break away from principle of the present utility model, carrying out, these improvement also should be considered as protection range of the present utility model.
