Introduction:
This type of tap changer is designed as step changeable facility used for capacity regulating transformer under non-energized condition. It is suitable
for three-phase oi-immersed capacity regulating with voltage rated 10kV and below, rated capacity 315kVA and below. It can be connected in series
and parallel system on LV and HV windings or connected b star or delta method through which to realize transformer capacity changeable. By this
way we can reduce iron loss and increase transformer load efficiency and power factor avoiding the phenomenon of "Big horse will drag small
carriage", and can be used to regulate voltage terminals.
