Abstract

En kretsbeskyttelsesanordning omfatter en seriekoplingskrets som er beregnet for å innkoples i en ledning i kretsen og vil kople om til en åpen tilstand når den utsettes for en overstrøm, og en shuntkoplingskrets som er åpen under normale driftsforhold, men vil avlede overstrømmen over kretsens belastning eller til Jord når den ut- løses av seriekoplingskretsen. Seriekop- lingskretsen omfatter fortrinnsvis en koplingstransistor (4) som styres av en styretransistor (6), og shuntkoplings- kretsen omfatter en shuntkoplingstran- sistor (9) som styres av en shuntstyre- transistor (11) som selv styres av seriekoplingskretsen. Shuntkoplingskret- sen kan være koplet til Jord eller den kan være koplet til en hjelpebelastning eller spenningsinnfoldingsanordning, såsom en triac.
