Abstract

Рассмотрены вопросы построения экспериментального стенда для исследования процессов работы тиристорного и транзисторного выпрямительно-инверторных преобразователей электровоза переменного тока в режиме тяги на высших зонах регулирования. Представлены осциллограммы процессов работы преобразователей в виде кривых тока и напряжения в первичной обмотке трансформатора и в цепи выпрямленного тока нагрузки (тягового двигателя), проведено их сравнение. Получены экспериментальные зависимости коэффициента мощности электровоза от изменения напряжения зоны.

The article discusses the problems of constructing an experimental stand to study the operation of reversible thyristor and transistor converters of AC locomotives in a traction mode on higher regulation zones. It provides and compares the oscillograph patterns of converter operation in the form of curves of voltage and current in the primary winding of the transformer and in the circuit of the rectified current of load (traction motor). Experimental dependences of the locomotive power factor on voltage change zones are obtained.
