Magnetism-shunting voltage regulation type transformer and magnetism-shunting voltage regulation method thereof

Abstract

The invention discloses a magnetism-shunting voltage regulation type transformer and a magnetism-shunting voltage regulation method thereof. The magnetism-shunting voltage regulation type transformer mainly comprises a main magnetic flux closed iron core frame (1), a primary coil (2) and a secondary coil (3). The magnetism-shunting voltage regulation type transformer is in parallel connection with one or more magnetic valves; magnetic columns positioned on two opposite edges of magnetic valve closed iron core frames (4) of the magnetic valves are respectively provided with one pair or more pairs of coils with a same number of turns; one end heads of each pair of coils are directly connected, and the other end heads are in series connection with a power supply; and a connecting iron core (5) is arranged between the main magnetic flux closed iron core frame (1) and the magnetic valve closed iron core frames (4). The magnetism-shunting voltage regulation method comprises the following steps: the main magnetic flux closed iron core frame (1) divides an integral 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 in parallel connection with one or more magnetic valves to form one or more magnetism-shunting magnetic circuits; and the magnetism-shunting magnetic circuits change the magnetic flux of a loop passing through a secondary winding by controlling the saturated degree of the magnetic valves to regulate the magnitude of secondary output voltages and output constant voltages. The invention can meet the requirement of a user on stabilized voltage.

Description

technical field [0001] The invention relates to a magnetic separation voltage regulating transformer and a method for regulating voltage by magnetic separation of the transformer Background technique [0002] The traditional transformer is an iron core frame, wound 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: In a practical transformer, the number of turns of the primary and secondary coils is fixed, that is, 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 the load, the voltage of the power grid will fluctuate, and the voltage value supplied to the user end deviates from the national standard limit value, and the electrical equipment at the user end cannot work near its rated voltage. When the voltage d...
