Description
резервной дакшы накаливани 2, При этом резервна лампа 2 (как и ранее лам 4а 1) шунтирует конденсатор 4, снижа на напр жение до величины напр51жени пи тани . Ввиду того, что катод стабилитрона в и анод THpHCTOlpa 8 соединеиы с плюсом источника питани через резервную лампу 2 п|эи выходе ее из стро стабилитрон 6 не цожет через участок управл ющий электрод катод - иристора 1 8 шунтировать конденс тор 4 и йапр жение на нем повышаетс и достигает н -пр жени пробо стабилитрона 7, запускающего тиристор 9, что обео« ;печивает вкпюченне резервной лампы нака- ливанэз 3. Работа у-:тройства ссушествл -, етс аналогично при лкйом количестве рв«аервных ламп. Backup Dakshi 2; At the same time, the backup lamp 2 (as before Lam 4a 1) shunts the capacitor 4, reducing the voltage to the voltage level of the power supply. Since the cathode of the Zener diode and the THpHCTOlpa 8 anode is connected to the plus power source through the backup lamp 2 and its output, the zener diode 6 does not flow through the control electrode of the cathode-arristode 1 8 bypassing the capacitor 4 and its voltage The rise of the Zener diode 7, which triggers the thyristor 9, increases and achieves n-test; it bakes an incandescent back-up lamp 3. The operation of the y-triggers is similar, with a small number of dim airbags.
