Abstract

Det er foreliggende oppfinnelses mål å frembringe en brukbar anordning av dig- itale beskyttelsesreléer også for små anlegg. Hele utbygningen er nådd, når det til forsyningen i et koblingsområde er anordnet to inngangsomvandlings- paneler (l) som hver er tilkoplet to bearbeidingsenheter (2). To bearbeid- ingsenheter (2) har en strømforsyning (3) hver. Ved at de enkelte universal- elementers store antall oppnås altså den nødvendige sikkerhet. Med oppfinnelsen er det for første gang mulig å lage et reserve beskyttelsesrelésystem, som lønnsomt kan brukes på alle anlegg. På den ene siden faller de høye prosjek- teringskostnadene bort og på den andre siden begrenser apparatteknikken seg til universalelementer.It is the object of the present invention to provide a usable device of digital protection relays also for small plants. The entire extension is achieved when two input conversion panels (1) are connected to the supply in a switching area, each of which is connected to two processing units (2). Two processing units (2) each have a power supply (3). Thus, the large number of individual universal elements is achieved with the necessary security. With the invention, it is possible for the first time to create a spare protection relay system, which can be used profitably on all plants. On the one hand, the high design costs fall away and on the other hand, the device technology is limited to universal elements.
