Abstract
Изобретение относитс к электротехнике и может быть использовано дл одноразового включени тиристора. Цель изобретени - обеспечение возможности одноразового отпирани тиристора. С этой целью нагрузка 2 зашунтирована цепочкой из последовательно соединенных резистора 10 и светодиода тиристорной оптопары 9, фототиристор которой подключен параллельно либо конденсатору 5, либо диоду 4. В результате при включении тиристора 1 возбуждаетс светодиод тиристорной оптопары 9, включаетс ее фототиристор и после включени тиристора 1 конденсатор 5 разр жаетс через фототиристор оптопары 9. Управл ющий переход тиристора 1 исключаетс из цепи протекани тока разр да конденсатора 5. Следовательно, после выключени тиристора 1 повторного его включени не происходит. 2 з.п. ф-лы, 2 ил.The invention relates to electrical engineering and can be used for a single turn on thyristor. The purpose of the invention is to provide the possibility of a one-time unlocking of the thyristor. For this purpose, the load 2 is shunted by a chain of series-connected resistors 10 and an LED of the thyristor optocoupler 9, the photothyristor of which is connected in parallel to either the capacitor 5 or diode 4. As a result of turning on the thyristor 1, the LED of the thyristor optocoupler 9 is energized, its photothyristor turns on and after the thyristor 1 is turned on the capacitor 5 is discharged through the photo-thyristor of the optocoupler 9. The control transition of the thyristor 1 is excluded from the flow circuit of the discharge current of the capacitor 5. Therefore, after the thyristor 1 turns off ornogo its inclusion does not happen. 2 hp f-ly, 2 ill.
