Description
technical field [0001] The invention relates to a transformer, in particular to a stepless on-load voltage regulating transformer. Background technique [0002] In practical applications, transformers need to be adjusted according to application requirements. Due to the limitation of its own structure, the existing transformer needs to adjust the voltage through the on-load voltage regulation and the voltage regulation of the series transformer. On-load voltage regulation refers to extracting the tap on the primary winding of the transformer, and using the on-load tap changer to change the number of turns of the primary winding, thereby changing the output voltage of the transformer. Series transformer voltage regulation refers to connecting the primary winding of the main transformer with the power supply, connecting the secondary winding of the main transformer with the secondary winding of the series transformer, and connecting the tapped winding of the main transformer ...
