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. |
