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.
