Description
залрещающсм ьходе .югическои части отсутствует и устройство защиты срабатывает .The logical part is missing and the protection device is activated.
При возникновении коммутационной дуги иоследн также воздействует на фютоэлектрический преобразователь, но одновременно шунтирует цепь электродов 3 и 4, зануска одновибратор. Одновибратор настроен на длительность импульса, )1шаюн;ую максимальное врем горени коммутедионно дуги, поэтому на запрещающем входе логической части защиты в течение времени горени коммутационной дуги имеетс сигнал и устройство защиты не срабатывает.In the event of a switching arc, the latter also acts on the photoelectric transducer, but simultaneously shunts the circuit of electrodes 3 and 4, a one-shot skimmer. The single-oscillator is tuned to the pulse duration, i) the maximum maximum burning time of the commutation arc, therefore, a signal is present at the inhibit input of the logical part of the protection during the burning time of the switching arc and the protection device does not operate.
Если процесс коммутации зат гиваетс , например аппарат ие может отключить критический ток, то по истечении выдержки времени одновибратора с логической части защиты он1имает с занретцаюну ситал п ycTpoiiство срабатывает.If the switching process is delayed, for example, the device can not turn off the critical current, then after the one-shot time delay from the logical part of the protection, it is deactivated, the sys- tem n ycTpotion is triggered.
