Abstract

The invention relates to a high voltage regulating autotransformer and belongs to the technical field of transformer manufacturing. According to the technical scheme, a serial winding of the autotransformer is serially connected with a voltage regulator. The voltage regulator comprises an iron core, a voltage regulator serial winding (6) and a voltage regulator excitation winding (7). The voltage regulator serial winding is serially connected with the serial winding (4) of the autotransformer. The voltage regulator excitation winding is connected with a power supply winding (2) of the autotransformer. A tapping regulating device of the voltage regulator is connected with the power supply winding of the autotransformer or the voltage regulator excitation winding. By regulating winding number of the power supply winding of the autotransformer, the voltage regulator excitation winding and the voltage regulator serial winding, voltage of the voltage regulator serial winding can be regulated freely during different tapping, and accordingly the voltage of the serial winding of the autotransformer is regulated, and precise high voltage regulation of the autotransformer is realized. The high voltage regulating autotransformer has the advantages that precise high voltage regulation of the autotransformer is realized.

Description

technical field [0001] The invention relates to a high-voltage voltage-regulating autotransformer, which belongs to the technical field of transformer manufacturing. Background technique [0002] At present, in the high-voltage power system, when the secondary voltage of the autotransformer reaches or exceeds 330kV, due to the limitation of the voltage tolerance level of the tap changer, the neutral point voltage regulation method is often used for voltage regulation of the high-voltage terminals. However, when the primary voltage of the autotransformer is relatively close to the secondary voltage, the neutral point voltage regulation method often cannot obtain the tapping voltage that meets the standard or user deviation requirements, which requires a new type of autotransformer that can Its high-voltage voltage is precisely regulated. Contents of the invention [0003] The object of the present invention is to provide a high-voltage voltage-regulating autotransformer, w...
