Transformer and shunting magnet voltage adjustment method thereof

Abstract

The invention discloses a transformer and a shunting magnet voltage adjustment method thereof. The transformer mainly comprises a main magnetic flux closed iron core frame (1), a primary coil (2) and a secondary coil (3), and is connected in parallel with one or more magnetic valves; one or more pairs of coils with equal winding turns are respectively arranged on magnetic columns on two opposite sides of a magnetic valve closed iron core frame (4) of each magnetic valve; the end sockets of each pair of the coils are connected directly, and the other end sockets are connected in series with a direct current supply; and a connection iron core (5) is arranged between the main magnetic flux closed iron core frame (1) and the magnetic valve closed iron core frame (4). The shunting magnet voltage adjustment method of the transformer comprises the steps as follows: the main magnetic flux closed iron core frame (1) divides the whole magnetic circuit into a primary magnetic circuit and a secondary magnetic circuit according to the primary coil (2) and the secondary coil (3), and then is connected in parallel with one or more magnetic valves, so as to form one or more shunting magnet circuit(s); in addition, the shunting magnet circuits change the magnetic flux traversing through a secondary winding loop by controlling the saturation degree of the magnetic valves, and can adjust the magnitude of the secondary output voltage, and can output constant voltage. The transformer and the shunting magnet voltage adjustment method thereof can satisfy the stabilized voltage requirement of a user.

Description

Technical field [0001] The invention relates to a transformer and a method for adjusting the voltage by dividing the magnetism of the transformer. Background technique [0002] The traditional transformer is an iron core frame with primary and secondary coils. The relationship between the primary and secondary voltage and the number of turns of the primary and secondary coils is as follows: For a practical transformer, the number of turns of the primary and secondary coils is fixed, namely This formula shows that the secondary voltage of the distribution transformer changes with the primary voltage of the grid, and the relationship is almost linear. Once the power grid changes due to load changes, the grid voltage will fluctuate, and the voltage supplied to the user side will deviate from the national standard limit. The user side electrical equipment cannot work near its rated voltage, the electrical equipment conversion efficiency is low, and the electrical energy waste is la...
