Control of thyristor keys on primary party transformer with voltage adjustment
Keywords:
the transformer with voltage adjustment, thyristor key, magnetisation current, magnetic inductionAbstract
Article is devoted to the analysis of work of thyristor keys on primary party of adding voltage and reducing voltage transformers. The interrelation of corners of switching off of thyristor key and an initial magnetic induc-tion at the moment of their inclusion is shown. Recommendations about a choice of corners of inclusion of
the thyristor key which are ensuring functioning of transformers without emissions of a current of magnetisation are made. Charts of currents, voltage and the magnetic induction, illustrating operation of the reducing the voltage transformer are provided. Results of work can be of interest for experts in the field of power electronics and semi-conductor converting equipment.
