Description

technical field [0001] The invention relates to a high-voltage adjustable transformer, more specifically, the invention relates to a high-voltage transformer with precise and controllable transformation ratio. Background technique [0002] In the field of high-voltage power transmission and distribution technology, adjustable transformers play a pivotal role. Specifically, transformers are devices that use the principle of electromagnetic induction to change AC voltage. The main components include primary coils, secondary coils, iron cores or magnetic cores. The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization, etc. According to the application, it can be divided into: distribution transformer, power transformer, fully sealed transformer, combined transformer, rectifier transformer, etc. Although there are many types of existing transformers, most of them are designed as a specific transformer structure. For s...

[0005] Another purpose of the present invention is to provide a high-voltage transformer with precise and controllable ratio in view of the design defects of the above adjustable transformer. The transformer is provided with an electromagnetic clutch, and the electromagnetic clutch is used to selectively link the motor and the rotor shaft. The preset voltage of the transformer is set in the controller, and then the controller controls the electromagnetic clutch linkage motor and the rotor shaft, and the motor drives the rotor shaft to rotate to adjust the transformation ratio of the transformer. At the same time, the voltage collector collects the output voltage of the transformer. When the output voltage of the transformer reaches When the voltage is preset, the controller controls the electromagnetic clutch to disengage from the motor and the rotor shaft, and the rotor shaft stops rotating quickly, avoiding the over-travel rotation of the rotor shaft, and realizing the precise ratio adjustment of the transformer. The invention solves the problem that the ratio of the adjustable transformer cannot be adjusted. Precise and controllable technical issues
