Description
коммутации тиристоров. В интерва.Тс; 300 - 360 эл. град., когда естественна коммутаци невозможна, от блока 2 тестовых сигналов подаютс импульсы, которые сравниваютс на логическом сравнивающем устройстве 3 с токовым сигналом, поступающим с преобразовател 1. Одновременное наличие сигналов с индикатора тока тиристора и тестовых сигналов свидетельствует о срыве коммутации.switching thyristors. In the interval.Tc; 300 - 360 email hail, when natural switching is impossible, pulses are sent from block 2 of the test signals, which are compared on the logic comparing device 3 with the current signal coming from converter 1. Simultaneous presence of signals from the thyristor current indicator and test signals indicates a breakdown of the switching.
Технико-экономическа эффективность изобретени обусловлена повыщением надежности индикации срыва коммутации управл емых вентильных преобразователей за счет упрощени схемы источника тестовых сигналов .The technical and economic efficiency of the invention is due to the increased reliability of the indication of the switching failure of controlled valve converters by simplifying the source circuit of test signals.
