Abstract
The utility model provides a voltage-regulating winding structure of an electric furnace transformer. The voltage-regulating winding structure comprises a transformer iron core, and is characterized in that the transformer iron core is provided with wires with the equal turn number from inside to outside; all the wires are connected end to end in sequence; an upper extending-out end and a lower extending-out end are arranged at the two ends of each wire; corresponding wiring ends are led out from the upper extending-out end and the lower extending-out end. According to the voltage-regulating winding structure of the electric furnace transformer, the turning numbers of different grades of the voltage-regulating windings are integrated into an integral multiple relation of each section and then the voltage-regulating windings are connected in series and are led out. The voltage-regulating winding structure has the beneficial effects that the occupied area is small and the cost of raw materials is reduced; compared with a traditional double-device-body electric furnace transformer, the electric furnace transformer adopts a single-device-body structure, so that the appearance size of the whole transformer is reduced and the economical benefits are remarkable; the manufacturability is good; by applying the voltage-regulating winding form, the structure of a product is simplified greatly and the transformer is convenient to operate, mount and maintain in covering and earth wire connecting process links of the transformer.
Description
Technical field
The utility model belongs to a kind of furnace transformer voltage-regulating winding structure, is mainly by the adjusting of output voltage, to meet the technological requirement of matallurgical products.
Background technology
Current conventional furnace transformer, due to Product Process requirement, the output of furnace transformer secondary output voltage equal difference, conventionally the method adopting is that furnace transformer adopts two machine body structures: a kind of is preposition self-pressure regulating transformer and main transformer combination, the another kind of series transformer structure that adopts,, all there is the defects such as complex process, material cost is high, floor space is large, failure rate height in above two kinds of structural shapes.
Summary of the invention
The purpose of this utility model will solve the technical problem that existing furnace transformer voltage regulating mode exists, a kind of furnace transformer voltage-regulating winding structure is provided, two device body transformer device structures are changed over to single machine body structure, structure of transformer body is simplified, also reduce the volume of material cost and whole product simultaneously, good manufacturability, practicality, safe and reliable.
The utility model is achieved in that
A kind of furnace transformer voltage-regulating winding structure, comprise transformer core, its special character is: in transformer fe, be provided with from the inside to the outside in the heart the wire of equal turn numbers, each wire joins end to end successively, wire two ends are provided with upper and lower lifting one's head, and on upper and lower lifting one's head, draw respective terminal.
Because furnace transformer is when the pressure regulation output voltage, change along with a number of turn, the magnetic flux density at center unshakable in one's determination is also corresponding to variation, belong to variable flux voltage regulation, if meet furnace transformer equal difference output voltage, every grade of pressure regulation number of turn of a winding is unequal, and this cannot realize conventional pressure regulation winding.And the utility model pressure regulation winding configuration becomes the integral multiple relation of every section by difference pressure regulation umber of turns at different levels by integration, then it mutually to be connected and drawn, its beneficial effect is:
1, floor space is little, reduces the cost of raw material
Compare with traditional two device body furnace transformers, this kind of furnace transformer adopts Dan Qi body mechanism, reduces the overall dimension of whole transformer, remarkable in economical benefits.
2, good manufacturability
Due to the application of this pressure regulation winding configuration, greatly simplify the structure of product, make transformer in suit, earth connection process procedure convenient operation, installation, easy to maintenance.

Fig. 1 is structural representation of the present utility model;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is elementary diagram of the present utility model;
Fig. 4 is arrangements of conductors schematic diagram.
Embodiment
As depicted in figs. 1 and 2, the utility model has a transformer core 4, on transformer core 4, be provided with from the inside to the outside the wire 1 of insulating paper cylinder 5 and equal turn numbers, it is example that the present embodiment be take 10 wires, between neighbouring two section leads, dovetail cushion block 7 is set, between each dovetail cushion block 7, by stay 6, connect, each root wire 1 joins end to end successively, every wire 1 two ends be provided with lift one's head 2 and under lift one's head 3.
As shown in Figure 3 and Figure 4,10 wires of the present embodiment are divided into upper and lower two-layer winding, upper and lower lifting one's head 2 respectively has 10, be respectively 1.～10., the 1. ` of `～10., in upper and lower lifting one's head on 2 and 3, draw respective terminal, the present embodiment, lifting one's head 1., 2., 3., 5., 7., 9. and 10. drawing seven nodes on `, is led to shunting switch.
During making, the wire of adjusting 1 together on winding former, 2 and 3 is carried out to mark by all wires upper and lower lifting one's head, it is carried out to Shape correction.Be inserted in transformer core 4, all lifting one's head is connected in series, need node to draw, drawn in shunting switch, then wrapping insulation.
