Abstract

Inventia se refera la un dispozitiv de protectie a grupului convertizor de alimentare a serviciilor auxiliare de la rame de metrou format dintr-un bloc de supraveghere a tensiunii de alimentare si un releu ale carui contacte auxiliare conditioneaza alimentarea grupului convertizor, deconectarea grupului convertizor fiind asigurata în afara tensiunilor limita normale de un comparator cu fereastra care printr-un etaj de temporizare, realizat cu un condensator si un comparator, comanda un tranzistor final ce are releul de actionare plasat în colector.The invention relates to a protection device of the subcontrol auxiliary power supply converter group consisting of a voltage supply monitoring block and a relay whose auxiliary contacts condition the supply of the converter group, the disconnection of the converter group being provided in outside the normal limit voltage of a comparator with the window, which through a timing stage, made with a capacitor and a comparator, controls a final transistor having the drive relay placed in the collector.
