Description
Technical field
Technical field of transformer manufacturing is the utility model is related to, a kind of specifically Vv of three column machine body structure of two-phase connects
Line tractive transformer.
Background technology
Tractive transformer is that the electric energy of three-phase electrical power system is transferred to two respective load-carrying single-phase traction circuits, point
Not Gei uplink and downlink locomotive power supply, tractive transformer be just used as three-phase become two-phase transformer.At present, domestic conventional Vv wiring
Tractive transformer is usually made of two single-phase transformers that capacity is identical or capacity is different, or by two single single-phase changes
Depressor device body is placed in a shared fuel tank and forms.Each device body uses single-phase double-column core structure, and each iron core column
Upper equal suit coil (i.e. two device bodies need 4 high-tension coils, 4 low-voltage coils, 4 voltage regulation coils altogether).For this knot
The tractive transformer of structure, needs that the coil of each device body first is carried out connection in series-parallel lead connection in inside, lifts one's head relatively more,
Extraction occupied space of lifting one's head is larger.The Vv Connection Traction Transformer volumes of the structure are larger, and copper consumption is more, and transformer weight is big,
Cause transformer of high cost, taking up a large area needed for transformer field installation.
Utility model content
For Vv Connection Traction Transformers volume is larger in the prior art, transformer is of high cost and live takes up a large area
The deficiencies of, problem to be solved in the utility model is to provide a kind of three column device of two-phase small, energy-saving, floor space is small
The Vv Connection Traction Transformers of body structure.
In order to solve the above technical problems, the technical solution adopted in the utility model is：
A kind of Vv Connection Traction Transformers of three column machine body structure of two-phase of the utility model, using a three-limb core,
One group of high-tension coil and low-voltage coil are set respectively on C columns, do not cover coil on B columns A,；A, two columns of C respectively set one and are tapped without excitation
Switch, from iron core, arrangement mode is coil outward：Iron core-low-voltage coil-high-tension coil-voltage regulation coil.
A, the first and last of C columns low-voltage coil brings out head and is connected by lead, directly leads out access low-tension bushing, A, C column respectively
High-tension coil head end is lifted one's head to be connected by lead, is directly accessed bushing, and high-tension coil end passes through lead and point of this column
Connect switch to be connected, after switch internal connects, two column lead-out wires access B column bushings parallel, and voltage regulation coil draws tap
Access of lifting one's head switchs.
A, the coil volume on C columns is identical or different.
Using a single machine body structure.
The utility model has the advantages that and advantage：
1. structure of transformer body is changed to three rod structure of two-phase by the utility model by two single-phase double-columns, line is reduced
Enclose copper consumption, more compact structure, reduces the floor space of transformer field installation, meanwhile, reduce the workload of each operation,
On the basis of properties of product are ensured, the cost of product is reduced, improves the benefit of manufacturing enterprise.
2. the utility model reduces the quantity of coil and extraction is lifted one's head, make connection inside device body simple, lead-out wire occupancy
Space reduces, and saves design cost.
Brief description of the drawings
Fig. 1 is that the Vv tractions of the utility model become machine body structure schematic diagram；
Fig. 2 is that the Vv tractions of the utility model become elementary diagram；
Fig. 3 is that the Vv tractions of the utility model become winding diagram.
Wherein, D is low-voltage coil；G is high-tension coil, and T is high pressure voltage regulation coil.
Embodiment
The utility model is further elaborated with reference to Figure of description.
As shown in Figure 1, the utility model iron core column uses three rod structures, three stems are connected with iron yoke up and down.Its
In one group of high-tension coil and low-voltage coil be set respectively on A, C column, the coil volume on A, C column can be identical, can not also
Together, coil is not covered on B columns.
As shown in Fig. 2, coil arrangement is to be respectively outward from iron core：Iron core-low-voltage coil-high-tension coil-pressure regulation
Coil.Two-phase number of coils is altogether 2 high-tension coils, 2 low-voltage coils, 2 voltage regulation coils), it is overall using a single device body
Structure.
As shown in Figure 2,3, A columns high-tension coil head end is lifted one's head marked as A, and end is lifted one's head to be gone out marked as X, low-voltage coil head end
Header laber is a, and end is lifted one's head marked as x；C phase high-tension coil head ends are lifted one's head marked as C, and end is lifted one's head marked as Z, low-voltage coil
Head end is lifted one's head lifts one's head marked as y marked as b, end.Per column coil, one off circuit tap changer is set.
In the utility model, lift one's head A, C of A, C column high-tension coil head end is introduced directly into bushing, access three-phase power system
Wherein two-phase in system.Lift one's head X, Z of the end of high-tension coil is connected with per the tap switch contact of column, after switch internal connects
Individually draw, link together, into B column bushings, access another phase in three-phase electrical power system.
In the utility model, A, C column low-voltage coil first and last, which bring out a, x, b, a y and directly leads out, connects low-tension bushing.Outside
Portion forms two respective load-carrying single-phase traction circuits.
The utility model application technology software carries out wave process, mechanical force, temperature rise, overload and internal electric field meter to product
Calculate, according to verification result, every technical parameter is satisfied by requiring.The structure type of three column of two-phase at the same time, reduce coil uses copper
Amount, reduces the size of transformer body, reduces the complexity of design and processes, reduces the workload of each operation, one
Determine to substantially reduce product cost in degree.Meanwhile the structure of product is compacter, reduce the occupation of land face of transformer field installation
Product.
