Abstract

The invention discloses a three-phase alternating current automatic voltage regulating device and a regulating method. The device comprises an intelligent control terminal, a voltage regulating module, an incoming box with three-phase alternating current input terminals A, B and C, an outgoing box with three-phase alternating current output terminals a, b and c and a current and voltage monitoringmodule. The voltage regulating module comprises a first voltage regulating transformer of each phase; The secondary side part of the first regulating transformer is grounded through the secondary side electric switch; The primary side part of the first voltage regulating transformer is connected with a three-phase AC input terminal and a three-phase AC output terminal through a primary side electric switch; The current and voltage monitoring module is arranged on the three-phase alternating current input terminal of the incoming terminal box and the three-phase alternating current output terminal of the outgoing terminal box. The intelligent control terminal is connected with the current and voltage monitoring module. The intelligent control terminal controls the primary electric switch and the secondary electric switch according to the three-phase input voltage and the user terminal load voltage to regulate the voltage.

Description

technical field [0001] The invention relates to the technical field of industrial voltage regulators, in particular to a three-phase AC automatic voltage regulating device and a regulating method. Background technique [0002] Usually the working voltage of the uniform output of the power grid is the same. When the user end is under light load, the voltage provided by the power grid will be too high, resulting in waste of resources. When the user end is fully loaded, the voltage provided by the grid will be too low to meet the normal voltage use of the user end, reducing work efficiency and work benefits. Contents of the invention [0003] In view of the defects in the background technology, the purpose of the present invention is to provide a three-phase AC automatic voltage regulator and a regulation method that can automatically adjust the three-phase output voltage according to the load operating voltage of the user end, so that the three-phase voltage balance error i...
