Abstract
The utility model discloses a transformer, wherein low-voltage copper bars do not have effect on winding sections and leads. The transformer comprises an iron core, three coils, a pair of upper press boards, a pair of lower press boards, three high-voltage leads and an even number of low-voltage copper bars, wherein the three coils are respectively wrapped on the iron core, the upper press boards and the lower press boards fix the iron core, the three high-voltage leads are arranged on one lateral press board of the iron core, the even number of low-voltage copper bars are arranged at the other side of the iron core and are respectively connected with the coils through the leads, and the coils at one side of each high-voltage lead are respectively connected with the low-voltage copper bars having the same number with the low-voltage copper bars at the other side of the iron core. The transformer has the beneficial effects that the coils at one side of each high-voltage lead are respectively provided with the low-voltage copper bars having the same number with the low-voltage copper bars at the other side of the iron core through the leads, and when production process requirements of an original transformer are met, the total size of each low-voltage copper bar is reduced by a half, and the weight is also reduced by a half. The low-voltage copper bars with reduced weight cannot lead the winding sections in the coils or the leads connected with the winding sections to be shifted, and the short circuit of the transformer is not generated.
Description
Technical field
The utility model relates to a kind of transformer.
Background technology
As depicted in figs. 1 and 2; Transformer comprise iron core 1, respectively be wrapped in three coils 9 and secured core 1 on the iron core 1 upper and lower two pairs of pressing plates 2, be arranged on three high-voltage connections 3 and 12 low-voltage copper bars 5 that link to each other with coil 9 through lead-in wire 4 on coil 9 one side guides 2; Be connected with four low-voltage copper bars 5 on each coil 9, and high-voltage connection 3 lays respectively at coil 9 both sides with low-voltage copper bar 5.Four winding segments (not drawing among the figure) are arranged on each coil 9, and the corresponding with it respectively lead-in wire 3 of each winding segments links to each other.Above-mentioned transformer is when being used for the workplace of big electric current (referring generally to the electric current more than the 20kA), and according to the technological requirement of transformer, the width of low-voltage copper bar 5 and cross-sectional area are all bigger, makes low-voltage copper bar 5 very greatly very heavy.Bring very big difficulty with regard to the assembling procedure of giving transformer like this.For example; Operating personnel need install low-voltage copper bar 5 by means of transportation, and because the gravity that low-voltage copper bar 5 receives is bigger, make low-voltage copper bar 5 after installation, be shifted easily; Adjacent winding segments in the coil 9 that this just makes with lead-in wire 4 links to each other can contact and produce friction; In case winding segments or the insulating barrier that goes between on 4 are worn, and are easy to cause transformer short-circuit, finally cause destroying the operation of whole transformer.
The utility model content
The utility model technical problem to be solved is: provide a kind of low-voltage copper bar winding segments and lead-in wire not to be had the transformer of influence.
For solving the problems of the technologies described above; The technical scheme that the utility model adopts is: a kind of transformer; Comprise iron core, respectively be wrapped in three coils and secured core on the iron core upper and lower two pairs of pressing plates, be arranged on three high-voltage connections and the even number that is arranged on the iron core opposite side on iron core one side guide through the low-voltage copper bar that lead-in wire and coil link to each other respectively, be positioned on the coil of high-voltage connection one side and be connected with and the identical low-voltage copper bar of iron core opposite side low-voltage copper bar quantity through lead-in wire respectively.
The low-voltage copper bar that is positioned at the coil homonymy links together through wire clamp, and wire clamp is fixedly connected with pressing plate.
The beneficial effect of the utility model is on the coil that is positioned at high-voltage connection one side, to be provided with and the identical low-voltage copper bar of iron core opposite side low-voltage copper bar quantity through lead-in wire respectively; And satisfy under the manufacturing technique requirent of original transformer; The overall dimension of each low-voltage copper bar reduces half the, and weight also just reduces half the.Low-voltage copper bar after weight reduces is not enough to make and winding segments in the coil or the lead-in wire displacement that links to each other with winding segments also just can cause transformer short-circuit.

Embodiment
Below in conjunction with accompanying drawing, describe the specific embodiments of the utility model in detail.
Like Fig. 3; Shown in Figure 4; The transformer of the utility model; Comprise iron core 1, respectively be wrapped in three coils 9 and secured core 1 on the iron core 1 upper and lower two pairs of pressing plates 2, be arranged on three high-voltage connections 3 and even number on coil 9 one side guides 2 through the low-voltage copper bar 5 that lead-in wire 4 and coil 9 link to each other respectively through supporting 6, be positioned on the coil 9 of high-voltage connection 3 one sides respectively through going between and 4 be connected with and the identical low-voltage copper bar 5 of iron core 1 opposite side low-voltage copper bar 5 quantity.The concrete quantity of low-voltage copper bar 5 is set according to the actual requirements.Be provided with 12 low-voltage copper bars 5 in for example original transformer; And be connected with four low-voltage copper bars 5 on each coil 9; The transformer of the utility model just is provided with 24 low-voltage copper bars 5 so; And each coil 9 is provided with 5, eight low-voltage copper bars 5 of eight low-voltage copper bars and is divided into two groups and lay respectively at coil 9 both sides, and promptly the both sides of each coil 94 are connected with four low-voltage copper bars through going between respectively.In order further to reduce low-voltage copper bar 5 because of the influence of gravity to winding segments in the coil and lead-in wire 4, the low-voltage copper bar 5 that is positioned at coil 1 homonymy links together through wire clamp 7, and wire clamp 7 is fixedly connected with pressing plate 2 through support 8.
The utility model has the advantages that: on the coil that is positioned at high-voltage connection one side, be provided with and the identical low-voltage copper bar of iron core opposite side low-voltage copper bar quantity through lead-in wire respectively; And satisfy under the manufacturing technique requirent of original transformer; The overall dimension of each low-voltage copper bar reduces half the, and weight also just reduces half the.Low-voltage copper bar after weight reduces is not enough to make and winding segments in the coil or the lead-in wire displacement that links to each other with winding segments also just can cause transformer short-circuit.
