Abstract

Daljinski razdvajač se upotrebljava da na prelaznoj stanici telefonske mreže jednog operatera, odredi mrežu drugog operatera u čijem se delu priključne mreže pojavio kvar, tj. da naponski razdvoji mreže radi vršenja merenja. Poznati su daljinski razdvajači na bazi TRIACS i MOS-FET-a, kode kojih se koristi jedan jedinstven prag uključivanja. Ako se upravljani silicijumski ispravljači (S1, S2) koriste kao elektronski prekidači (12a, 12b), tada su prekidači medjusobno povezani jednim spojnim elementom (40), kako bi se mogli birački impulsi preneti do telefonske centrale (10) i prekidač koristiti sa ne osetljivim upravljačkim priključcima. Primena samoblokirajućeg MOS-FET-a sa režimom obogaćivanja omogućuje, prema pronalasku, visok prag uključivanja i nizak prag isključivanja, tako da se mogu koristiti uobičajeni postupci merenja opadanja napona. takodje je moguće da se učini da prag uključivanja bude zavisan od polarnosti.
