Abstract
FIELD: thermal nondestructive testing of power equipment. SUBSTANCE: method for timely detecting faulty thyristors used in thyristor converters involves control and forecasting of variations in a difference between the actual temperature of thyristor structure and a temperature obtained on the basis of an equivalent thyristor model. EFFECT: improved procedure of testing without turning a product to be tested as a whole on a special test mode.

Изобретение относится к области теплового неразрушающего контроля силовой электротехники, в частности тиристоров тиристорных преобразователей. Способ предназначен для своевременного выявления дефектных тиристоров, используемых в тиристорных преобразователях, без вывода изделия, в специальный контрольный режим. Положительный эффект достигается за счет контроля и прогнозирования изменения разности между фактической температурой структуры тиристора и полученной с помощью его эквивалентной модели.The invention relates to the field of thermal non-destructive testing of power electrical engineering, in particular thyristor thyristor converters. The method is intended for the timely detection of defective thyristors used in thyristor converters, without outputting the product into a special control mode. A positive effect is achieved by monitoring and predicting changes in the difference between the actual temperature of the thyristor structure and obtained using its equivalent model.
