Abstract: The on-load tap-changer is the important part for transformer in pressure regulating process. Introduction was made to the arc extinguishing scheme of traditional mechanical and mixed on-load tap-changer, the improved process of the on-load tap-changer was summarized and three kinds of improved schemes were given and compared. It is pointed out that the full electric power electronic type on-load tap-changer will be the trend of development.
Key words: transformer; on-load tap-changer; mechanical; mixed; arc extinguishing
