Abstract

The invention relates to the technical field of electric power, in particular to a series of automatic voltage stabilizing devices for power transformers, and more particularly relates to a voltage regulating device for a double-winding transformer. The power transformer is provided with a voltage combination winding formed by connecting a plurality of groups of tuning windings and a plurality of groups of external voltage adjusting devices in a one-to-one correspondence manner, and a series of power transformer automatic voltage stabilizing devices formed by a protection device, an operation system, a main control system and a driving system. The device has the advantages of being easy to control, safe, reliable, high in voltage regulating speed, wide in input voltage, high in voltage stabilizing precision and long in continuous safe operation time.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a double-winding transformer voltage regulator. Background technique [0002] Transformers are important equipment for power grid distribution. At present, all regions of the world are in the peak period of power construction, and the problem of tight power supply needs to be solved urgently. In order to alleviate the tense situation of power supply, power companies in various regions of the world have increased the total length of transmission lines, increased the investment scale of power grid construction, and further expanded the transformation capacity, providing a broad development space for the transformer industry and promoting the transformer industry. Good development of manufacturing industry. [0003] Voltage quality problems include the following: [0004] ①Voltage deviation: the operating voltage value is in the range of ±10% of the rated voltage value; ...
