Abstract

The invention provides a line voltage regulating transformer with a vector conversion function. The voltage regulating transformer includes a vector conversion coil group, a voltage regulating coil and a voltage regulating iron core. The voltage regulating coil is installed on the voltage regulating iron core, and two groups of voltage regulating transformers are installed. The vector conversion coil group includes two coils, which are coaxially wound on two sets of voltage regulating iron cores and outside the voltage regulating coils, so that the two sets of voltage regulating iron cores become vector iron cores at the same time. It is a line voltage regulating transformer installed in the middle of the line using vector phase conversion to solve the problem of low single-phase transmission voltage in rural low-voltage systems. The vector coil and iron core structure are designed to convert the 380-volt, 120-degree The biphase voltage with phase angle is converted into single-phase voltage without phase (vector conversion); the voltage regulating coil structure is designed to automatically increase the voltage of vector conversion online to the voltage range required by the user. It solves the problem of low voltage caused by the end load and wire diameter of the built line.

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...
