This series of tap changers is suitable for oil-immersed power transformers with frequency of 50 Hz, rated voltage of 10 kV to 35 kV and rated current of 63 A to 250 A. When voltage regulation is required, the transformer must be disconnected from the grid. Under the condition of no excitation, the voltage of the transformer can be adjusted by changing the number of turns of the primary coil of the transformer. The purpose of adjusting the secondary output voltage of the transformer can be realized by adjusting the secondary output voltage of the transformer.
