Description

В устройствах релейной защиты и автоматики примен ютс  реле времени с использованием в качестве нуль-индикатора полупроводникового триода, база которого управл етс  напр жением конденсатора, а эмиттер присоединен к делителю напр жени .Relay protection and automation devices use a time relay using a semiconductor triode as a null indicator, the base of which is controlled by the voltage of a capacitor, and the emitter is connected to a voltage divider.

Дл  повышени  точности работы реле предлагаетс , согласно изобретению , конденсатор и делитель напр жени  присоедин ть к общему источнику ПОСТОЯННОГО тока.To improve the accuracy of the relay, it is proposed, according to the invention, to connect a capacitor and a voltage divider to a common source of DC current.

На чертеже изображена принципиальна  электрическа  схема предлагаемого реле.The drawing shows the principal electrical circuit of the proposed relay.

В реле, с целью снижени  потребл емой мощности, в качестве нульиидикатора применен полупроводниковый триод /. Эмиттер триода питаетс  от делител  напр жени  2, а база управл етс  напр жением, снимаемым с конденсатора 3, зар жающегос  через сопротивлени  4. Выходное реле 5, включенное в коллектор триода, срабатывает, когда напр жение на конденсаторе 3 становитс  несколько меньшим напр жени  на э п ттepe. Плавна  регулировка уставки времени реле осуществл етс  регулировкой сопротивлений 4 в цепи зар да конденсатора.In the relay, in order to reduce power consumption, a semiconductor triode is used as a null indicator. The triode emitter is powered by voltage divider 2, and the base is controlled by the voltage removed from capacitor 3 charged through resistance 4. Output relay 5 connected to the triode collector triggers when the voltage on capacitor 3 becomes slightly less than voltage e p ptepe. A smooth adjustment of the time delay of the relay is made by adjusting the resistances 4 in the capacitor charge circuit.

С целью уменьшени  зависимости выдержки времени от колебаний напр жени  псточиика тока, конденсатор 3 и делитель напр жений 2 подключены к общему источнику посто нного тока.In order to reduce the dependence of the time delay on voltage fluctuations of a pstochik of the current, the capacitor 3 and the voltage divider 2 are connected to a common source of direct current.

Предмет изобретени Subject invention

Реле времени с применением в качестве нуль-индикатора нолупрозодникового триода, база которого управл етс  напр жением конденсатора , а эмиттер присоединен к делнтелю напр женн , о тли чаю Hie ес  тем, что, с целью повыщепи  точности работы реле, конденсатор и дслитель напр жени  присоединены к общему источнику посто нного тока.A time relay using a nipple-slip triode as a null indicator, whose base is controlled by the voltage of a capacitor, and the emitter is connected to a voltage divider, which is connected to the Hie by that to a common source of direct current.
