Abstract

The invention provides an implementation method and device for finely and rapidly adjusting impedance of a transformer, and relates to the technical field of power systems and electronics. The device for finely and rapidly adjusting the impedance of the transformer comprises a control system and a transmission mechanism, and the transmission mechanism comprises a servo motor, a movable ferromagnetic shunt, a limiting guide rod and a transmission belt wheel. According to the implementation method and device for finely and rapidly adjusting the impedance of the transformer, the impedance value of the analog transformer can be set through a human-computer interface, a PLC automatically drives a servo motor according to preset programming, and the impedance value of the analog transformer can be accurately adjusted. And the lap joint area of the movable ferromagnetic shunt and the main iron core of the analog transformer is adjusted, and calculation and verification are automatically completed, so that the impedance of the analog transformer is finely and quickly adjusted to reach a set value, the adjustment accuracy is high, and time is saved.

Description

technical field [0001] The invention relates to the technical field of power systems and electronics, in particular to a method and device for realizing fine and rapid adjustment of transformer impedance. Background technique [0002] A transformer is a device that uses the principle of electromagnetic induction to change the AC voltage.
