0) connection.It is 120 ° that the end of b phase low-voltage coil lifts one's head the angle that the top that lags behind b phase low-voltage coil along coiling direction lifts one's head; It is 120 ° that the end of c phase low-voltage coil lifts one's head the angle that the top that lags behind c phase low-voltage coil along coiling direction lifts one's head; Lift one's head in the top of a phase low-voltage coil and end is lifted one's head at same position; Make the circle appearance of long and last circle of c phase low-voltage coil of the circle of last circle of b phase low-voltage coil etc. and to be less than the circle of last circle of a phase low-voltage coil long.The axis of a phase low-voltage coil and the axis of c phase low-voltage coil are all positioned on same plane M, and the axis of b phase low-voltage coil is positioned in the plane N vertical with plane M; Lift one's head in the top of b phase low-voltage coil and c phase low-voltage coil is all positioned at the left side of plane N, and the end of b phase low-voltage coil is lifted one's head and a phase low-voltage coil is all positioned at the right side of plane N.
In the present embodiment, the end of a phase low-voltage coil is lifted one's head and is lifted one's head binding post 1 by a phase end tap lead wire 2 and three-phase end and be connected, the end of b phase low-voltage coil is lifted one's head and is lifted one's head binding post 1 by b phase end tap lead wire 3 and three-phase end and be connected, and the end of c phase low-voltage coil is lifted one's head and lifted one's head binding post 1 by c phase end tap lead wire 4 and three-phase end and be connected; Lift one's head and lift one's head binding post 8 by a phase top tap lead wire 5 and a phase top and be connected in the top of a phase low-voltage coil, lifting one's head and lift one's head binding post 9 by b phase top tap lead wire 6 and b phase top and be connected in the top of b phase low-voltage coil, lifts one's head and lift one's head binding post 10 by c phase top tap lead wire 7 and c phase top and be connected in the top of c phase low-voltage coil; The resistance of b phase top tap lead wire 6, the resistance of b phase end tap lead wire 3 and the resistance sum of b phase low-voltage coil equal the resistance of c phase top tap lead wire 7, the resistance of c phase end tap lead wire 4 and the resistance sum of c phase low-voltage coil, and equal the resistance of a phase top tap lead wire 5, the resistance of a phase end tap lead wire 2 and the resistance sum of a phase low-voltage coil.C phase end tap lead wire 4 in the present embodiment comprises the first lead-in wire and the second lead-in wire, lift one's head with the end of c phase low-voltage coil and be connected in one end of first lead-in wire, the other end is connected with second one end gone between at the axis place of c phase low-voltage coil, and the other end of the second lead-in wire is extended along the axis place plane M of the axis of a phase low-voltage coil and c phase low-voltage coil to a phase low-voltage coil and lifted one's head binding post 1 by common lead and three-phase end and is connected; Lift one's head with the end of b phase low-voltage coil and be connected in one end of b phase end tap lead wire 3, the other end and second goes between and is connected; Lift one's head with the end of a phase low-voltage coil and be connected in one end of a phase end tap lead wire 2, the other end and second goes between and is connected.Taking this connected mode, the object that three-phase resistance balances can be realized easily by regulating b phase end tap lead wire 3 and/or a phase end tap lead wire 2 and the second tie point position gone between.
Because transformer is in different size, and the lateral separation between low voltage outlet terminals has difference, so will calculate resistance balance when selecting lead-in wire copper bar in implementation process.As shown in Figure 3, b phase low-voltage coil is 2/3rds circle length with last circle of c phase low-voltage coil, that is: the internal resistance of b phase low-voltage coil and c phase low-voltage coil is equal; And b phase top tap lead wire 6 and b phase end tap lead wire 3 length sum are greater than c phase top tap lead wire 7 and c phase end tap lead wire 4 length sum; Therefore c phase end tap lead wire 4 copper bar area is suitably reduced to reach b, c phase resistance equal.A phase top tap lead wire 5 and a phase end tap lead wire 2 length sum are less than c phase top tap lead wire 7 and c phase end tap lead wire 4 length sum, but all many 1/3rd circle length of last last circle of turn ratio b phase low-voltage coil of a phase low-voltage coil and last circle of c phase low-voltage coil, by regulating the size of a phase end tap lead wire 2, a phase can be reached equal with b, c phase resistance.Therefore, the low voltage lead structure of the present embodiment does not need the resistance balance realizing three-phase as in Chinese patent literature CN 201199479Y by repeatedly bending a phase top tap lead wire, a phase end tap lead wire, c phase end tap lead wire and c phase top tap lead wire.Lift one's head in top due to b phase low-voltage coil and end is lifted one's head respectively in b phase low-voltage coil both sides, and last circle of b phase low-voltage coil is 2/3rds circle length (that is: few 1/3rd circle length), lifted one's head in the top of b phase low-voltage coil to lift one's head with b phase top that the distance of binding post 9 is relative diminishes, the end of b phase low-voltage coil is lifted one's head and to be lifted one's head with three-phase end that the distance of binding post 1 is also relative to diminish.So this is implemented low voltage lead structure disclosed in relative Chinese patent literature CN 201199479Y and saves material, reduce product cost, and reduce the wastage.
Low voltage lead structure of the present invention is applicable to the winding of three-dimensional wound core dry type transformer and oil-immersed type transformer, relative to traditional low pressure head mode (as Chinese patent literature CN201199479Y), a, x lift one's head invariant position, and thus their low-voltage lead length is all short; The position of b, y changes, because y is through window unshakable in one's determination, can ensure that output voltage is constant, and last circle actual is few around [namely last circle is around lifting one's head position to top, a discontented circle, as around 2/3rds circle length], moreover the distance that b, y go out in b phase both sides to a, c phase shortened relatively originally to some extent, this has just made b phase top lift one's head to lift one's head with end total length short (i.e. resistance decreasing), to reach the object (namely the two resistance is tending towards equal) close to a phase length.Last circle of c phase low-voltage coil is few around [namely last circle is around lifting one's head position to top, is discontented with a circle, as around 2/3rds circle length], makes c phase length close to a phase length (namely, resistance is tending towards equal).This consumption decreasing b, c phase winding material, can also reach the object of three-phase equilibrium, thus achieves the technique effect killed two birds with one stone.
In addition, the end of b phase low-voltage coil lift one's head angle that the top that lags behind b phase low-voltage coil along coiling direction lifts one's head also can for being greater than 0 °, be less than or equal to other numerical value between 300 °; The end of c phase low-voltage coil lift one's head angle that the top that lags behind c phase low-voltage coil along coiling direction lifts one's head also can for being greater than 0 °, be less than or equal to other numerical value between 180 °.All can realize saving material, loss is low, and the goal of the invention of three-phase resistance balance.
In addition, the end of c phase low-voltage coil is lifted one's head also can lift one's head along the top of coiling direction advanced c phase low-voltage coil that [namely last circle is around continuing around a segment distance completely afterwards, but not through window unshakable in one's determination], the angle lifted one's head in the top of its advanced c phase low-voltage coil is for being greater than 0 °, being less than or equal to 60 °.The end of a phase low-voltage coil is lifted one's head the top that also can lag behind a phase low-voltage coil along coiling direction and is lifted one's head, and the angle lifted one's head in its top lagging behind a phase low-voltage coil is for being greater than 0 °, being less than or equal to 60 °.The end of a phase low-voltage coil is lifted one's head also can lift one's head along the top of coiling direction advanced a phase low-voltage coil that [namely last circle is around continuing around a segment distance completely afterwards, but not through window unshakable in one's determination], the angle lifted one's head in the top of advanced a phase low-voltage coil is for being greater than 0 °, being less than or equal to 180 °.All can realize saving material, loss is low, and the goal of the invention of three-phase resistance balance.
The invention utilizes to change three-phase (a, b, c) low-voltage coil lift one's head position, simplifying lead-in wire dexterously and arranging, reach materials and reduce, and the object that three-phase coil balances.Not only performance meets the demands, and also reduces loss.Thus achieving saving material, loss is low, the goal of the invention of three-phase resistance balance.
Above-described embodiment is only for the invention example is clearly described, and the restriction not to the invention embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all execution modes.And thus the apparent change of extending out or variation be still among the protection range of the invention claim.
