Description
ДОТ / подаетс отпирающий иилульс на тиристор 22. То-К замыкаетс по цетси: 29- 22-il9-28-29 и убывает не скачком, а постепемйо. Машнитиа энерги индуктивности 29 переходит еэлектрическую энергию конденсатора 19. Если в ПрОЦессе широтно-имлульсного рйгулировали запира;йие ДОТ 1 промежуточное (т. е. за ним следует отширание того же ДОТ У), то на тирвстор 25 отпирающий импульс не подаетс . В этом случае процесс заканчиваетс , иогд.а ток у|бы1вает до .нул и тиристор 22 е1Стест1в&ннЫМ образам затираетс . Конденсатор 19 хра-нит зар д того же знака до очерёдного запирани ДОТ /. При последнем его запирании -в данном периоде (т. е. когда следующим должен работать ДОТ 4) одновременно .подаютс отпирающие импульсы на оба тирнстора 22 и 25, причем импульс на тлристоре 25 .должен иметь длительность несколько бо.льше полавины периода собственных колебаний цепи 19- 29; тогда ток вначале по-прежнему зар жает конденсатор 19, но после своего убывани до нул (тиристор 22 «гаснет) меи ет знак ш .протекает по депи: 19-25- 29-28-19. При этом (конденсатор 19 вначале разр жаетс , отдава энергию ано.дной индукти1вност,и 29 и источнику 28 (т. е. в питающую сеть), а затем зар жаетс другим знаком за счет энергии индуктивности 29. В результате ,к первому запиранию ДОТ 4 подготаюливаютс тание же услови , какие существовали nipK первом запирании ДОТ /. При этом в установившемс режиме начальные значени напр жени на конденсаторе .19 при за.п.ирани:и ДОТ 1 и ДОТ 4 равны по вел,нч1и«е и отличаютс то.лько знаком.The bunker / unlocking switch on the thyristor 22 is applied. To-K closes in cetsy: 29-22-il9-28-29 and decreases not stepwise, but gradually. The power engineering inductance 29 transfers the electrical energy of the capacitor 19. If the lockout was corrected in the POS process, i.e., the expansion of the same DOT U followed, then the trigger pulse is not applied to the thyristor 25. In this case, the process is terminated, and the current is up to the voltage and the thyristor 22 of the test and in the same way is lost. Capacitor 19 stores the charge of the same sign to the next lock DOT /. During its last locking, in a given period (i.e., when DOT 4 should work as the next), unlocking pulses are applied simultaneously to both Tyrnstors 22 and 25, and the pulse on Tlristor 25 should have a duration slightly more than half of the natural oscillation period 19-29; then the current initially still charges the capacitor 19, but after decreasing to zero (the thyristor 22 "goes out), the sign w. flows across the depy: 19-25-29-28-19. At the same time (the capacitor 19 is first discharged, giving away the energy of the anode one inductance, and 29 and the source 28 (i.e., to the power supply network), and then charged with another sign due to the energy of the inductance 29. As a result 4 the same conditions as the nipK first locking of the DOT / were prepared. At the same time, in the established mode, the initial values of the voltage on the capacitor .19 with the return of the dipstick: and DOT 1 and DOT 4 are equal in lead, but “e” and differ in just a sign.
