Description
стора 11. Необходимое врем подогрева электродов (.примерно 1,5 сек) определ ет емкость конденсатора 8 и величина резистора 12. В момент включени дополнительного тиристора 11 шунтируетс цепь управлени основного тиристора 7. При переходе тока резистора 7 через нулевое значение он запираетс , и конденсатор 8 зар жаетс до величины, большей, чем амплитудное значение напр жени сети, что обеспечивает надежное зажигание лампы. Конденсатор 8 выполн ет две функции: обеспечивает требуемое врем подогрева электродов лампы и шовышает амплитудное значение наир жени на лампе в момент ее зажигани .stopper 11. The required heating time of the electrodes (approximately 1.5 sec.) determines the capacitor 8 capacitance and the value of resistor 12. At the moment the additional thyristor 11 is turned on, the main thyristor 7 control circuit is bridged. When the current of the resistor 7 goes over the zero value, it closes and the capacitor 8 is charged to a value greater than the magnitude of the mains voltage, which ensures reliable ignition of the lamp. The capacitor 8 performs two functions: it provides the required time for heating the lamp electrodes and shoots the amplitude value of finding out on the lamp at the time of its ignition.
;В исходное состо ние схема быстро возвраш ,аетс с помощью разр дного резистора 9.; The circuit quickly returned to its original state using the discharge resistor 9.
