Abstract
Изобретение относитс к автоматике дл обеспечени бесперебойного энергоснабжени . Цель изобретени - снижение уровн помех, устранени гальванической св зи между фидерами и упрощение устройства . Устройство содержит коммутирующий элемент (реле), две цепи формировани импульсов управлени , пороговый элемент, трансформатор, диодный мост, два конденсатора и п ть резисторов. В исходном состо нии нагрузка 5 и первична обмотка трансформатора 17 подключены к основному фидеру 3. При исчезновении напр жени на основном фидере 3 цепь 6 прекращает формирование световых импульсов управлени на тиристор 22 оптрона 10. Тиристор 22 запираетс , транзистор 23 закрываетс , напр жение на конденсаторе 26 начинает повышатьс за счет зар дного тока, протекающего через резистор 25 от зар женного до полного напр жени конденсатора 20. На выходе диода 14 оптрона 15 формируютс световые имспульсы управлени , поступающие на тиристор 27, который открываетс , открыва при этом транзистор 24. Обмотка 2 обтекаетс током, контакты коммутирующего элемента 1 переключают нагрузку 5 и первичную обмотку трансформатора 17 на резервный фидер 4. 2 ил.The invention relates to automation to ensure uninterrupted power supply. The purpose of the invention is to reduce the level of interference, eliminate galvanic communication between the feeders and simplify the device. The device contains a switching element (relay), two control pulse shaping circuits, a threshold element, a transformer, a diode bridge, two capacitors, and five resistors. In the initial state, the load 5 and the primary winding of the transformer 17 are connected to the main feeder 3. When the voltage on the main feeder 3 disappears, circuit 6 stops the formation of light control pulses on the thyristor 22 of the optocoupler 10. The thyristor 22 is closed, the transistor 23 is closed, the voltage on the capacitor 26 begins to increase due to the charge current flowing through the resistor 25 from the capacitor 20 charged to full voltage. At the output of the diode 14 of the optocoupler 15, control light pulses are applied to the thyristor 27, which opens, thereby opening the transistor 24. The winding 2 is wrapped around the current, the contacts of the switching element 1 switch the load 5 and the primary winding of the transformer 17 to the backup feeder 4. 2 Il.
