Title: Load voltage reactor control - has transformer primary tap connected to reactor and anti-parallel thyristors with junction tied to source
Inventor: YARNYKH LEONID VASILIEVICH
IPC: H02J3/12
Filed: 1981-01-19
Abstract: The primary of the transformers is provided with a tap and is connected to a reactor, which in turn is connected to the source. One junction of the antiparallel thyristor arrangement is also connected to the source while the other junction is linked to a tap on the transformer primary. Under minimal load the transformer operates with its lowest transformation ratio since the thyristors (8,9) are off and thus all turns of the primary (2) are active. In addition, an additional voltage drop is caused by the reactor (7) which is in series with the primary, and as a result the output of the secondary (3) is reduced. With a higher load and reduced voltage of the secondary, the conduction angle of the thyristors (8,9) is increased and thus the transformation ratio of the transformer is raised reducing the loss across the reactor. The design is particularly suitable for feeding steel melting arc furnaces.
