off-Circuit Tap Changer Transformer Load Break Switch off Load Tap Changer

Introduction

This type of tap changer has two kinds of products, they are of vertical type and horizontal type. It is usually

used in three-phase and single-phase oil-immersed power transformer with frequency of 50, 60 Hz, rated

voltage 10~66 kV, rated current from 63A to 1000A. It can be regulated on middle or neutral terminal. It can be

equipped directly on transformer tank or transformer tank wall working under non-energized condition.

Off-circuit Capacity Regulating Tap Changer

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
