Abstract
Inventia se refera la un circuit de protectie si semnalizare a scurtcircuitelor pe sarcina, la limitatoarele inductive, de proximitate tip HN, la care pe un rezistor de valoare mica, înseriat cu tranzistorul final si cu sarcina limitatorului, se obtine o cadere de tensiune proportionala cu curentul de sarcina care, în cazul unui scurtcircuit la bornele sarcinii, devine mai mare decât 0,65V, încât aduce în conductie un grup de tranzistoare complementare care amorseaza în tiristor, cu ajutorul caruia se blocheaza tranzistorul final al limitatorului, curentul prin sarcina anulându-se, semnalizarea fiind facuta cu un LED înseriat cu tiristorul reducerea schemei în stare initiala fiind posibila printr-o manevra de deconectare-conectare de la sursa de tensiune.The invention relates to a circuit for protection and signaling of short-circuits on load, to inductors, proximity type HN, in which on a small value resistor, connected to the final transistor and with the load of the limiter, a voltage drop proportional to the load current which, in the event of a short to the terminals of the load, becomes greater than 0.65V, to bring into conduction a complementary group of transistors which primes into the thyristor, by means of which the end transistor of the limiter is blocked, the signaling being done with a LED connected to the thyristor, the reduction of the initial state diagram being possible by a disconnection-connection maneuver from the voltage source.
