Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings of the specification.

[0022] Such as figure 1 As shown, the transformer voltage regulating winding arrangement structure of the present invention has low voltage winding D, high voltage winding G, no-load voltage regulating winding and on-load voltage regulating winding Y. The winding arrangement of the above-mentioned windings is: low voltage winding-high voltage winding-regulating Voltage winding, in which the on-load voltage-regulating winding Y is in the middle, and the unloaded voltage-regulating windings are two groups, namely the first no-load voltage-regulating winding W and the second no-load voltage-regulating winding W′, two groups of no-load voltage-regulating windings Connected in parallel, symmetrically placed on the upper and lower parts of the on-load voltage regulating winding Y. On-load voltage regulating winding Y and no-load voltage regulating winding a...

Abstract

The invention relates to a transformer regulating winding arrangement structure and a winding method. The structure is provided with a low-voltage winding, a high- voltage winding, no-load regulating windings and an on-load regulating winding, the arrangement mode of the above windings is that the low-voltage winding, the high-voltage winding and the regulating windings, wherein the on-load regulating winding of the regulating windings is placed in the middle, the number of the no-load regulating windings is two, and the no-load regulating windings are symmetrically placed on the upper portion and the lower portion of the on-load regulating winding. The transformer regulating winding arrangement structure saves space, can reduce the dimension of the length direction of a transformer and the dimension of the width direction of the transformer, reduces the occupied space of the transformer, lightens the total weight of the transformer, meets the requirements for wide-range voltage regulating, lowers the complexity of design, processes and production, greatly improves labor productivity, and increases the reliability of operation.

Description

Technical field [0001] The invention relates to the technical field of transformer manufacturing, in particular to a transformer voltage regulating winding arrangement structure and winding method. Background technique [0002] At present, the voltage regulating windings used on the high voltage side of 220kV transformer products in power equipment are all single, that is, a voltage regulating method. No-load and on-load voltage regulating methods exist separately. Usually the position of the voltage regulating winding of the transformer is generally Put it on the inside or outside of the high-voltage winding. This arrangement is suitable for the high-voltage winding with a single voltage regulation method. This single voltage regulation method has little effect on the small change of the power grid, and cannot capture the subtle changes of the power grid instantly. The current industrial and economic development has led to a large demand for industrial power and a wider range of...
