Abstract
The utility model discloses an auto-transformer winding structure and relates to a transformer. The utility model is to provide an auto-transformer winding structure with low additional loss and close impedance of all tapping short-circuits. The utility model has the technical proposal that an auto-transformer winding structure includes a series winding; the series winding includes two same windings which are respectively arranged on both sides of an oil gallery and symmetrically provided with taps. The utility model is used for transformers.
Description
Technical field:
The utility model relates to a kind of transformer, particularly a kind of variac winding construction.
Background technology:
Traditional transformer winding structure is laminar winding or continous way winding, winding technique becomes the integral body of a polyphone continuously, and this variac can cause each tap leakage field imbalance, supplementary load loss are bigger, and can not satisfy the close needs of each tap short-circuit impedance of this automatic coupling voltage regulator.
Summary of the invention:
The purpose of this utility model provides a kind of variac winding construction, and the supplementary load loss of this winding construction are low and each tap short-circuit impedance is close.The technical solution of the utility model is that a kind of variac winding construction comprises the series connection winding, it is characterized in that: the series connection winding is the both sides that two identical windings are located at oil duct respectively, and this two winding is provided with tap respectively symmetrically.The utility model has the little advantage close with the tap short-circuit impedance of supplementary load loss compared with the prior art.
Description of drawings:
Fig. 1 is a front view of the present utility model, and Fig. 2 is the A-A half sectional view of Fig. 1.
Embodiment:
In conjunction with above accompanying drawing the utility model is elaborated, in order to solve the uneven and not close problem of tap short-circuit impedance of each tap leakage field, at the both sides of oil duct 7 difference coiling series connection winding 2, and to this both sides winding make respectively the symmetry tap 6, the quantity of tap can be provided with as required, as nine taps, remaining common winding 1, iron core 3, main insulation 4, main empty path 5 and oil duct 7 are identical with existing structure.Owing to adopted said structure, therefore the utlity model has the little advantage close of supplementary load loss of each tap with each tap short-circuit impedance.
Claims (1)
1, a kind of variac winding construction comprises the series connection winding, it is characterized in that: the series connection winding is the both sides that two identical windings are located at oil duct respectively, and this two winding is provided with tap respectively symmetrically.
