Abstract

The invention provides a line voltage regulating transformer with a vector transformation function. The voltage regulating transformer comprises a vector transformation coil set, voltage regulating coils and voltage regulating iron cores. The voltage regulating coils are installed on the voltage regulating iron cores, and the two sets of voltage regulating coils and voltage regulating iron cores are installed on each voltage regulating transformer. The vector transformation coil set comprises two coils, and the two coils are coaxially wound outside the two sets of voltage regulating coils andvoltage regulating iron cores, so that the two sets of voltage regulating coils become vector iron cores simultaneously. The line voltage regulating transformer is installed in the middle section of aline, conducts transformation through a vector phase and is used for solving the problem that a country low-voltage system single-phase transmission voltage is low; the vector coils and an iron corestructure are designed, and a double-phase voltage of 380 V and with a phase angle of 120 degrees free of zero lines is transformed into a phase-free single-phase voltage (vector transformation); a voltage regulating coil structure is designed, and the voltage subjected to the vector transformation is automatically raised to the voltage range needed by a user on line. The low voltage problem, caused by the problems of a tail end load and the line diameter, of an already built line is solved.

Description

technical field [0001] The invention relates to the technical field of rural low-voltage distribution networks, in particular to a line voltage regulating transformer with a vector conversion function. Background technique [0002] Due to the complicated line laying, scattered farmers, irregular power consumption and other reasons in the rural power grid, there has been a problem of low voltage at the end of the user for a long time. Especially for a small number of single-phase power transmission users, the problem of low voltage has been difficult to solve. The present invention uses a vector transformation method to change single-phase power transmission into two-phase power transmission and adds a boost system at the rear end, which can perfectly solve this problem. Contents of the invention [0003] In order to solve the problems described in the background technology, the present invention provides a line voltage regulating transformer with a vector conversion funct...
