Description
() УСТРОЙСТВО ДЛЯ ЗАЩИТЫ ПАРАЛЛЕЛЬНО ВКЛЮЧЕННЫХ ПОЛУПРОВОДНИКОВЫХ ТРИОДОВ() DEVICE FOR PROTECTION OF PARALLELALLY INCLUDED SEMICONDUCTOR TRIODES
Изобретение относитс к защите полупроводниковых структур.This invention relates to the protection of semiconductor structures.
По основному авт.св. № известно устройство защиты параллельно включенных полупроводниковых триодов, например в схемах стабилизаторов .напр жени , содержащее чувствительный и сигнализирующий элементы , причем чувствительный элемент выполнен в виде плавких предохранителей , включенных в цепи коллекторов триодов, а сигнализирующий элемент - в виде триода типа п-р-п с индикатором в цепи коллектора,эмиттер которого подключен к общей точке всех предохранителей, а база через диодную сборку - к коллекторам контролируемых триодов } J.According to the main auth. No. a protection device for parallel-connected semiconductor triodes is known, for example, in voltage regulator circuits containing a sensitive and signaling element, the sensitive element being designed as fuses included in the circuit of the triode collectors and the signaling element as a n-p- triode n with an indicator in the collector circuit, the emitter of which is connected to the common point of all fuses, and the base through the diode assembly to the collectors of controlled triodes} J.
Однако устройство имеет ограниченные функциональные возможности, Так как не обеспечивает индивидуальный контроль предохранителей в цеп х контролируемых триодов.However, the device has limited functionality, as it does not provide individual control of the fuses in the controlled triodes.
Цель изобретени - расширение функциональных возможностей. Эта цель достигаетс тем, что устройство снабжено резистором, включенным в цепь базы триода типа п-р-п, а диодна сборка выполнена на светодиодах .The purpose of the invention is to expand the functionality. This goal is achieved by the fact that the device is equipped with a resistor included in the base circuit of a pnp type triode, and the diode assembly is made on LEDs.
На чертеже представлена схема устройства защиты.The drawing shows a diagram of the protection device.
Устройство содержит плавкие The device contains fusible
10 предохранители 1, включенные в цепи коллекторов контролируемых триодов 2, диодную сборку (схему ИЛИ) на светодиодах 3, сигнализирующий элемент 4, выполненный в виде трио1$ да типа п-р-п с индикатором в цепи коллектора,, резистор SВ исправном состо нии сигнализирующий элемент нормально закрыт, поскольку участок база-эмиттер его 10 fuses 1, included in the collector circuits of controlled triodes 2, diode assembly (OR circuit) on LEDs 3, signaling element 4, made in the form of trio $ 1 and type pnp with an indicator in the collector circuit the signaling element is normally closed, since its base-emitter section
20 триода замкнут через сопротивление небольшой величины.Triode 20 is closed through a small resistance.
