Abstract
The utility model belongs to the transformer, relates to a lead structure of a Vv couple traction transformer, characterized in that: two one-way traction transformers are combined, head ends of windings of adjacent iron core poles of two high-voltage windings are directly connected and led out; the winding direction of one low-voltage winding is opposite to the winding direction of another low-voltage winding, the winding directions of the windings on the adjacent iron core poles of the low-voltage windings are same and opposite to the winding directions of the low-voltage windings on another two iron core poles, namely the winding directions of the iron core pole (2) and the iron core pole (3) are same, the winding directions of the iron core pole (1) and the iron core pole (4) are same. The lead structure of Vv couple traction transformer has the following beneficial effects: convenient installation and simple structure and is applied on the 11-220kV level traction transformer.
Description
Technical field
The utility model belongs to transformer, relates to the pin configuration that a kind of Vv connects traction transformer.
Background technology
Existing Vv connects the pin configuration of traction transformer; Two unidirectional traction transformer combinations; Low pressure winding II ' iron core column 3., 4. with low pressure winding I ' iron core column 1., 2. winding is identical; Winding head end on two adjacent iron core column of high pressure group intersects to link to each other draws, inconvenient operation so not only, and also very not attractive in appearance.
Summary of the invention
The utility model provides a kind of Vv easy for installation, simple in structure to connect the pin configuration of traction transformer in order to remedy the deficiency of prior art.
The utility model is realized through following technical scheme:
The Vv of the utility model connects the pin configuration of traction transformer, and its special character is: the winding head end in two unidirectional traction transformers combinations, two adjacent iron core column of high pressure group directly links to each other and draws; One low pressure group around to an other low pressure group around on the contrary; Winding on two adjacent iron core column of low pressure group is around to identical; With low pressure winding on two other iron core column around on the contrary; Be iron core column 2. with iron core column 3. around to identical, iron core column 1. with iron core column 4. around to identical, iron core column 2. with iron core column 1. around on the contrary.
The beneficial effect of the utility model is, and is easy for installation, simple in structure, is applied to 110～220kV level traction transformer.
Description of drawings
Fig. 1 is an existing structure connection principle sketch map, and Fig. 2 is the utility model connection principle sketch map, is the high pressure winding above, is the low pressure winding below, has identified instantaneous main flux, inductive current direction, and wiring position.Fig. 3 is the existing structure sketch map.Fig. 4 is the utility model structural representation.
Among the figure: 1 high-voltage connection, 2 standing tree, 3 cover plates.
Embodiment
Accompanying drawing 2,4 is a kind of specific embodiment of the utility model.
The Vv of the utility model connects the pin configuration of traction transformer, two unidirectional traction transformers combinations, and winding head end A, B, C on two adjacent iron core column of high pressure group directly link to each other and draw; One low pressure group around to an other low pressure group around on the contrary; Winding on two adjacent iron core column of low pressure group is around to identical; With low pressure winding on two other iron core column around on the contrary; Be iron core column 2. with iron core column 3. around to identical, iron core column 1. with iron core column 4. around to identical, iron core column 2. with iron core column 1. around on the contrary.The lead-in wire of low pressure winding is respectively a1, x1 and a2, x2.
Two capacity single-phase transformer device bodies equal or that do not wait are installed in the same fuel tank, and three terminals of high pressure winding are connected into the V wiring, and four terminals of low pressure winding are all drawn, and outside fuel tank, are connected into Vv0 or Vv6 as requested.The application of unidirectional traction transformer in three-phase power supply system that Here it is.With the low pressure winding on iron core wherein around to adjustment, the iron core column that is about to low pressure winding II ' iron core column 3., 4. become low pressure winding IV ' 3., 4., go between can be easy to operate and more attractive in appearance for the transformer high-low pressure like this.
Two unidirectional traction transformer combinations; Low pressure winding on the adjacent iron core column of two iron core group is around to identical; With low pressure winding on two other iron core column around on the contrary; The iron core column that is low pressure winding III ' iron core column 2., low pressure winding IV ' is 3. around to identical, and the iron core column of winding III ' iron core column 1., winding IV ' is 4. around to identical.
