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.The remote separator is used to determine the network of another operator at the transitional station of the telephone network of one operator, in whose part of the connected network a fault has occurred, ie. to voltage disconnect the networks for measurements. Remote separators based on TRIACS and MOS-FET are known, the codes of which use a single switching threshold. If the controlled silicon rectifiers (S1, S2) are used as electronic switches (12a, 12b), then the switches are interconnected by one connecting element (40), so that the selective pulses can be transmitted to the telephone exchange (10) and the switch used with no sensitive control connections. The use of a self-blocking MOS-FET with an enrichment mode allows, according to the invention, a high switching threshold and a low switching threshold, so that conventional voltage drop measurement procedures can be used. it is also possible to make the switching threshold dependent on polarity.
