Abstract
The utility model discloses a phase-shifting rectifier transformer lead structure, which comprises low-voltage outlet tapping boards and an auxiliary lead tapping board. An A-phase coil, a B-phase coil and a C-phase coil are arranged sequentially, and the auxiliary lead tapping board is arranged below the A-phase coil, the B-phase coil and the C-phase coil. The phase-shifting rectifier transformer lead structure is characterized in that the auxiliary lead tapping board below the B-phase coil and the C-phase coil is provided with a-phase terminals, b-phase terminals and c-phase terminals. The a-phase terminals, the b-phase terminals and the c-phase terminals on the auxiliary lead tapping board are arranged at the lower ends of the B-phase coil and the C-phase coil in a centralized manner, so that the distance from the auxiliary lead terminals to low-voltage outlet terminals on one side of the A-phase coil is increased, the insulation distance and the creep distance among the low-voltage outlet terminals are ensured, and the electric strength of the phase-shifting rectifier transformer lead structure is enhanced.
Description
Technical field
A kind of pin configuration that is applicable to many secondary phase-shifting rectifier transformer of the utility model design.
Background technology
As shown in Figure 1, the auxiliary lead tapping plate 2 of existing phase-shifting rectifier transformer is fixed on the insulation board by the insulated bolt group, and auxiliary lead tapping plate 2 and low pressure outlet tapping plate 1 are positioned at the same side of transformer.Expansion along with the phase-shifting rectifier transformer occupation rate of market, the specification of product grows with each passing day, and the restriction that required by client's overall dimensions, if low pressure outlet 1 and auxiliary lead tapping plate 2 all are arranged in transformer one side, the creepage distance of insulation between the terminal just can not guarantee.
Summary of the invention
Goal of the invention: the utility model proposes a kind of improved transformer auxiliary lead structure at the deficiency of existing phase-shifting rectifier transformer auxiliary lead structure, guarantees insulation distance between auxiliary connection terminal and low pressure outlet terminal by this structure.
In order to solve the problems of the technologies described above, the utility model has adopted following technical scheme: a kind of phase-shifting rectifier transformer pin configuration comprises low pressure outlet tapping plate and auxiliary lead tapping plate; A phase coil, B phase coil and C phase coil set gradually, and described auxiliary lead tapping plate is arranged on A phase coil, B phase coil and C phase coil below; It is characterized in that: on the auxiliary lead tapping plate below B phase coil and the C phase coil, be provided with a phase terminal, b phase terminal and c to terminal.
Wherein, a phase terminal be positioned at the B phase coil under; The b phase terminal is positioned under the gap of B phase coil and C phase coil; The c phase terminal be positioned at the C phase coil under.
Beneficial effect: the utility model is concentrated a phase terminal, b phase terminal and c phase terminal on the auxiliary lead tapping plate lower end that is arranged on B phase coil and C phase coil, the low pressure outlet terminal that makes auxiliary lead terminal and A phase coil one side is apart from becoming greatly, guarantee insulation distance and creepage distance between the low pressure outlet terminal, strengthened the electrical strength of product.
Description of drawings
Fig. 1 is the pin configuration schematic diagram of original phase-shifting rectifier transformer.
Fig. 2 is a pin configuration schematic diagram of the present utility model.
Embodiment:
Below in conjunction with accompanying drawing the utility model is done further explanation.
As shown in Figure 1, the auxiliary lead structure of phase-shifting rectifier transformer of the present utility model is: at the two ends up and down of three-phase coil one side difference strap 10, be positioned at A phase coil 3 one sides on the clamping plate 10 and be provided with the insulation board that is used to install low pressure outlet tapping plate 1, three low pressure outlet tapping plates 1 vertically are provided with, the two ends of low pressure outlet tapping plate 1 are separately fixed on the insulation board, on each low pressure outlet tapping plate 1 some low pressure outlet terminals 4 are set.Two third-class offices on clamping plate 10, just the gap location of A phase coil 3, B phase coil 8 and C phase coil 9 vertically is provided with two insulation boards, is provided with auxiliary lead tapping plate 2 in the insulation board lower end; On auxiliary lead tapping plate 2, be provided with a phase terminal 5, b phase terminal 6 and c to terminal 7.
As shown in Figure 2, the utility model is concentrated the lower end that is arranged on B phase coil 8 and C phase coil 9 with a (x1, x2, x3) phase terminal 5, b (y1, y2, y3) phase terminal 6 and c phase terminal 7; Wherein a (x1, x2, x3) phase terminal 5 is positioned under the center of B phase coil 8; B (y1, y2, y3) phase terminal 6 is positioned under the gap of B phase coil 8 and C phase coil 9; C (z1, z2, z3) phase terminal 7 is positioned under the center of C phase coil 9.Bottom the distance of low pressure outlet terminal 4 becomes big on a (x1, x2, x3) phase terminal 5 and the low pressure outlet tapping plate 1, and the creepage distance of insulation between the terminal is guaranteed.
The above only is a 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 improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
