Abstract
The utility model discloses the zero-emission of a kind of low press seal line, comprise row, zero-emission, copper strips, insulation board mutually, described row is mutually located in two interlaced superimposed zero-emissions; Described copper strips is located between two zero-emissions of arranging junction mutually; Described insulation board is located between adjacent two zero-emissions of arranging centre mutually; The utility model is by the obstruct of insulation board, make two of adjacent line resistance and lie farthest away mutually between row arrange mutually between the difference of line resistance more and more less, thus the unbalanced phenomenon of eliminating transformer line resistance, guarantee the balance of Three-Phase Transformer coil D.C. resistance.
Description
Technical field
The utility model relates to during transformer is installed the low press seal line zero-emission connected.
Background technology
Three-phase transformer product is widely used in industrial and mining enterprises, textile machine, printing packaging, petrochemical industry, school, market, elevator, post and telecommunications, medical machinery, office equipment, testing equipment, industrial automation equipment, household electrical appliance, skyscraper, lathe, all occasions needing normal voltage to ensure such as the power transmission and distribution in tunnel and import equipment.The D.C. resistance unbalance factor of the coil of three-phase transformer is the important performance parameter of in transformer testing, and its size directly has influence on the voltage of Three-Phase Transformer coil, the balance of electric current.Meet national standard in order to ensure this performance parameter, as shown in Figure 1-2, generally make envelope line zero-emission into area larger copper bar or a copper bar in parallel again on original specification copper bar, to eliminate the unbalanced phenomenon of line resistance.Particularly some jumbo products, in order to ensure the balance of its D.C. resistance, the consumption of its envelope line zero-emission is very large, and this way not only wastes resource, and improves cost.
Utility model content
Utility model object: for the problems referred to above, the utility model provides the zero-emission of a kind of low press seal line, is guaranteeing under the prerequisite that DCR of Transformer balances, and reduces the consumption of envelope line zero-emission.
Technical scheme: a kind of low press seal line zero-emission, comprises row, zero-emission, copper strips, insulation board mutually, and described row is mutually located in two interlaced superimposed zero-emissions; Described copper strips is located between two zero-emissions of arranging junction mutually; Described insulation board is located at adjacent row mutually between two middle zero-emissions.
Particularly, described row mutually can be provided with multiple according to the length of zero-emission, and the utility model is preferably three.
Particularly, the number of described copper strips is n-1 that arranges number mutually, and the utility model is preferably two.
Particularly, described insulation board is identical with copper strips number, and the utility model is preferably two.
Particularly, described insulation board is epoxy plate.
Particularly, described row and zero-emission are mutually bolted, and each row is mutually provided with four bolts.
Beneficial effect: compared with prior art, the utility model is by the obstruct of insulation board, make two of adjacent line resistance and lie farthest away mutually between row arrange mutually between the difference of line resistance more and more less, thus the unbalanced phenomenon of eliminating transformer line resistance, guarantee the balance of Three-Phase Transformer coil D.C. resistance.

Embodiment
Below in conjunction with the drawings and specific embodiments, illustrate the utility model further.
As shown in 3-5, a kind of low press seal line zero-emission, comprise arrange 1 mutually, zero-emission 2, copper strips 3, insulation board 4, describedly arrange 1 mutually and have three, be respectively a phase, b phase, c phase, arranging 1 is mutually located in two interlaced superimposed zero-emissions 2, wherein a phase connects the zero-emission 2 of the part that staggers by bolt 5, the zero-emission 2 that part accounts for 1/4, b phase of each zero-emission 2, c phase connects lamination portion respectively by bolt 5 of staggering, lamination portion accounts for 3/4 of each zero-emission 2, and each row 1 is mutually connected with zero-emission 2 by four bolts 5; Described copper strips 3 has two, is located at respectively between two zero-emissions 2 of b phase, c connection; Described insulation board 4 is epoxy plate, has two, is located at a phase respectively with b phase centre, between b phase and two zero-emissions 2 of c phase middle.
The utility model, by the obstruct of insulation board 4, makes the difference of the line resistance between the line resistance between ab, bc and ac more and more less, thus the phenomenon of eliminating transformer ab, bc, ac top-stitching resistance unbalance, guarantee the balance of Three-Phase Transformer coil D.C. resistance.
