Description

Известные реле минимального напр жени  с выдержкой времени дл  защиты электроустановок содержат электромагнитный элемент минимального напр жени  и механизм выдержки времени, встроенные в привод выключател .Known undervoltage time delay relays to protect electrical installations include an undervoltage electromagnetic element and a time delay mechanism built into the switch actuator.

Предлагаемое реле отличаетс  от известных тем, что в нем применена защелка, освобождаема  электромагнитом элемента минимального напр жени  и осуществл юща  пуск механизма выдержки времени. Дл  возврата реле в исходное положение после восстановлени  напр жени  служит силовой электромагнит, включаемый контактом механизма времени.The proposed relay differs from the known ones in that it uses a latch, which is released by the electromagnet of the minimum voltage element and starts the time delay mechanism. To reset the relay to its original position after the voltage has been restored, a power electromagnet is used, activated by a time contact.

Такое выполнение реле позвол ет получить независимую от величины напр жени  выдержку времени и повышает надежность работы реле.Such an embodiment of the relay makes it possible to obtain a time delay independent of the voltage value and increases the reliability of the operation of the relay.

На чертеже изображена схема предлагаемого реле.The drawing shows a diagram of the proposed relay.

Реле содержит электромагнитный элемент / минимального напр жени , анкерный механизм 2 выдержки времени с контактной системой 3, механизм 4 свободного расцеплени  и силовой электромагнит 5.The relay contains an electromagnetic / undervoltage element, a time delay anchor mechanism 2 with a contact system 3, a free trip mechanism 4 and a power electromagnet 5.

При срабатывании элемента 1 минимального напр жени  освобол даетс  защелка 6 механизма выдержки времени, который позвол ет механизму 4 свободного расцеплени  отключить выключатель. При восстановлении напр жени  силовой электромагнит 5 возвращает реле в исходное положепие. Все устройство питаетс  от трансформатора напр жени  защищаемой электроустановки и встроено в привод выключател .When the minimum voltage element 1 is triggered, the latch 6 of the time delay mechanism is released, which allows the free tripping mechanism 4 to open the circuit breaker. When the voltage is restored, the power electromagnet 5 returns the relay to its original position. The entire device is powered by the voltage transformer of the protected electrical installation and is built into the switch drive.
