Abstract
The utility model discloses a high voltage D on-load tap changing transformer which comprises an iron core, a lower voltage winding, a medium voltage winding and a high voltage winding, and further comprises full-intertwined type structured voltage regulating windings which are connected in parallel in a top-bottom mode and are arranged outside the high voltage winding. The lower voltage winding, the medium voltage winding and the high voltage winding are arranged from the iron core to the outside. A line is led out from the middle of the high voltage winding. According to the high voltage D on-load tap changing transformer, a full-intertwined type structure is adopted by the regulating windings, shock resistance performance is improved, the structure of the transformer is simple, leading and outgoing of the line are convenient, and insulating properties are good.
Description
Technical field
The utility model relates to a kind of novel electric power transformer, relates in particular to a kind of high voltage D and is connected to the voltage adjustment of on-load transformer.
Background technology
