Description
лупериод отключаетс тиристор 4 и включаетс тиристор 3, т. е. тиристоры в этом режиме осуществл ют функции выпр мительных диодов.The loop turns off the thyristor 4 and turns on the thyristor 3, i.e. the thyristors in this mode perform the functions of a rectifying diode.
Ток управлени тиристорами 3 и 4 не зависит от характера нагрузки и определ етс только величиной напр жени вторичной обмотки трайоформатора 1 и ограамчительными резисторами И и 12.The thyristor control current 3 and 4 does not depend on the nature of the load and is determined only by the voltage value of the secondary winding of the transformer 1 and the limiting resistors I and 12.
В аварийном режиме работы, т. е. при перегрузках или коротких замыкани х в нагрузке , прекращаетс ток через светодиоды блока дл ко«трол уровн тока оптоэлектронных ключей.In emergency operation mode, i.e., in case of overloads or short circuits in the load, the current through the LEDs of the unit is stopped to control the current level of the optoelectronic switches.
При прохождении переменного напр жени через нуль или при приходе обратной полуволны напр жени фототиристоры 9 и 10 отключаютс , т. е. прекращаетс управление силовыми тиристорами 3 и 4, которые также отключаютс , т. е. выполн ют в данном режиме функцию ключей. Напрузка отключаетс от источника переменного напр жени .When the alternating voltage passes through zero or when the reverse half-voltage arrives, the photo thyristors 9 and 10 are turned off, i.e. control of the power thyristors 3 and 4, which also turn off, i.e., perform the function of keys in this mode. The load is disconnected from the AC source.
Элемент 6 может быть не только стабилизатором , но и преобразователем нацр жени .Element 6 can be not only a stabilizer, but also a national converter.
Таким образом, предложенное устройство обеспечивает эффективную защиту низковольтных источников питани независимо от характера сглаживающего фильтра и нагрузки .Thus, the proposed device provides effective protection for low-voltage power sources, regardless of the nature of the smoothing filter and the load.
