Abstract

Fjernstyrt skilleinnretning er nødvendig for ved overgangspunktet mellom telenettet for en bruker og nettet for en annen bruker å kunne fastslå i hvilken del av de sammenkoblede nett det er oppstått en feil, dvs. for å kunne skille nettene fra hverandre llkespen- nlngsmessig slik at målinger kan foretas. Det er tidligere kjent fjernstyrte skilleinnretnlnger med triacenheter og MOS-FET-enheter der det benyttes en bestemt koblingsterskel. Blir styrte silisiumlike- rettere benyttet som elektroniske brytere blir bryterne forbundet med hverandre med et koblingsledd for å kunne overføre valgpulser fra en telefon til en sentral og for å kunne anvende brytere med ufølsomme styrlngstil- koblinger. Bruken av selvsperrende MOS-felteffekttransistorer av oppladningstypen muliggjør ifølge oppfinnelsen en høy innkoblingsterskel og en lav utkoblingsterskel slik at vanlige målemetoder for spenningssenknlngen kan anvendes. Det er også mulig å gjøre innkoblingsters- kelen avhengig av spenningens polaritet.Remote controlled separation device is required to determine at the transition point between the telecommunications network of one user and the network of another user in which part of the interconnected networks an error has occurred, ie in order to be able to separate the networks from each other voltage-wise so that measurements can be made. made. Prior art remote sensing devices with triac units and MOS-FET devices are known, where a specific switching threshold is used. If controlled silicon rectifiers are used as electronic switches, the switches are connected to each other by a switching link to be able to transmit selection pulses from a telephone to a switchboard and to be able to use switches with insensitive control connections. According to the invention, the use of self-locking MOS field effect transistors of the charge type enables a high switch-on threshold and a low switch-off threshold, so that conventional measurement methods for the voltage cut can be used. It is also possible to make the switching threshold dependent on the voltage polarity.
