Air cored
series & Shunt Reactor, Upto 2 MVA , Upto 33Kv, ONAN / AN A variable
transformer, reactor having a core combining at least two complete core
elements with a common yoke; primary winding divided into two
independently fed sets of phase coils wound in opposite direction,
arranged on symmetrical legs of core elements and separated by the
common yoke; secondary winding with each phase coil divided into two
wound in opposite direction portions carried by symmetrical core legs,
adjacent to the primary coils and separated by common yoke. The
secondary short-circuited reactor winding is reduced to at least one
close loop member with loop portions separated by the common yoke. The
single, poly phase apparatus has at least one primary coil per set that
includes a controllable device in circuit relation therewith to enable
control of one primary coil relative to the other, either in current
magnitude or in current phase shift. The controllable device being
either a silicon control rectifier or transistor. |
