Abstract

The invention relates to the technical field of electric power, in particular to an automatic voltage stabilizing device for a power transformer, and more particularly relates to a distribution transformer voltage stabilizer, which is characterized in that a avoltage combined winding formed by connecting plural groups of tuning windings and external plural groups of voltage adjusting devices in one-to-one correspondence manner, a protection device, an operating system, a master control system and a driving system are arranged on a power transformer to form a series of power transformer automatic voltage stabilizing devices. The distribution transformer voltage stabilizer of the invention has the beneficial effects of simple control, safety, reliability, fast voltage regulation speed, wide input voltage, high voltage stabilization precision and long continuous safe operation time.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a distribution transformer voltage stabilizing device. 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 the manufacturing industry. [0003] Electricity is one of the most important energy sources used in modern industry, agriculture and modern social life. Voltage changes widely affect va...
