Abstract
The utility model discloses a zero line flat cable connection structure of a balancing transformer winding wire resistor. The zero line flat cable connection structure comprises an a-phase flat cable, a b-phase flat cable, a c-phase flat cable, an original zero line flat cable and an additional zero line flat cable. A protrusion is arranged in the middle of the additional zero line flat cable, and two ends of the additional zero line flat cable are respectively connected with the a-phase flat cable and the b-phase flat cable. The protrusion in the middle of the zero line flat cable is arranged above the b-phase flat cable, an interval is arranged between the protrusion in the middle of the zero line flat cable and the b-phase flat cable, and the additional zero line flat cable and the b-phase flat cable are fully insulated with each other. According to the zero line flat cable connection structure of the balancing transformer winding wire resistor, when the unbalance rate of the transformer winding wire resistor exceeds a regulated standard deviation range, a difference value of the transformer triple-phase wire resistor can be small, and the unbalance rate of the wire resistor can meet a regulated standard requirement. Due to the fact that the thickness of the additional zero line flat cable is just a half of an additional zero line flat cable of an original connection structure, a material-saving effect is obvious, and manufacturing cost of enterprises is reduced.
Description
Technical field
The utility model relates to a kind of zero line row syndeton of balancing transformer winding wire resistance, the processing when being used for Transformer Winding and the line resistance imbalance occurring and exceed standard.
Background technology
When the Transformer Winding line resistance unbalance factor occurs and exceeds the deviation range that national standard allows, be exactly off quality, solution in the past be on the basis of original transformer device structure simply again and on the zero line row of a certain size specification, reach the requirement of Three-Phase Transformer line resistance balance by improving the resistance of respectively organizing line resistance.Adopt this simple zero line row syndeton that manufacturing cost is increased a lot, cause extra loss to enterprise, reduced the benefit of managing.
The utility model content
The utility model purpose: with not enough, the utility model provides a kind of zero line row syndeton of saving the balancing transformer winding wire resistance of cost for problems of the prior art.The connection zero line row's who increases by change structure and the connected mode of arranging mutually with transformer originally, improve the resistance of Transformer Winding line resistance, reach and adopt a small amount of material just can make the purpose of transformer wire resistance balance, reduced the manufacturing cost of enterprise, improve the effectiveness of operation of enterprise.
Technical scheme: a kind of zero line of balancing transformer winding wire resistance row syndeton comprises that a arranges mutually, b arranges mutually, c arranges mutually, original zero-emission and increase zero-emission; The middle part of described increase zero-emission is projection, and two ends are arranged mutually to arrange mutually with c with a respectively and are connected; The middle part projection that increases zero-emission is positioned on b arranges mutually, and between arranging mutually with b, spacing is arranged, and described spacing makes and increases zero-emission and open with the mutually drained all insulation of b; The thickness of described increase zero-emission is 1/2nd of original structure increase zero-emission thickness.
The middle part of described increase zero-emission is square projection.
The two ends of described increase zero-emission are arranged mutually to arrange mutually with c with a respectively by bolt or welding manner and are connected.
On the basis of original transformer connection syndeton, the zero line of required increase row's planform is improved, and the zero-emission of increase is only arranged with a, c mutually by bolt or welding manner be connected, and with b mutually fully insulation open.
Beneficial effect: compared with prior art, the zero line row syndeton of balancing transformer winding wire resistance provided by the utility model, when transformer winding wire resistance unbalance rate is above standard the deviation range of stipulating, can make the difference of Three-Phase Transformer line resistance less, the line resistance unbalance factor just can meet the requirement of standard code, the thickness of arranging due to the zero line that increases only has former syndeton to increase half that zero line is arranged thickness, and the material-saving successful has reduced enterprise's manufacturing cost.
Description of drawings
Fig. 1 is zero line row syndeton schematic diagram in prior art;
Fig. 2 is the zero line row syndeton schematic diagram of the utility model embodiment.
Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model.
As shown in Figure 2, a arranges 1 mutually, b arranges 2 mutually, c arranges mutually 3 and is arranged on original zero-emission 4, and the middle part that increases zero-emission 5 is square projection, and two ends are bolted respectively arranges mutually 1 at a and arrange mutually on 3 with c; The middle part projection that increases zero-emission 5 is positioned at b arranges outside 2 mutually, and between arranging 2 mutually with b, spacing is arranged, and described spacing makes and increases zero-emission 5 and b and arrange mutually 2 and insulate open fully.Wherein, the thickness of increase zero-emission 5 is 1/2nd of original zero-emission 4 thickness.
The above is only preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvement, these improvement also should be considered as protection range of the present utility model.
