Abstract

Et plasmalysbue brennersystem omfatter en feilregistre-j ringskrets for registrering av en kortslutning mellom* elektrode og dyse og for å sperre strømf or syningen når I en kortslutning er registrert. En registreringskrets i brennerkabelen er anordnet for å utløse feilregistreringskretsen når kabelen blir alvorlig punktert.j Registreringskretsen omfatter en folie som er leiret i kabelen som omgir hovedlederen, med hvilken en avløps-ledning er forbundet. Avløpsledningen registrerer- en kortslutning mellom folie og hovedleder som følge av et inntrengende fremmedlegeme og utløser feilregistre-i ringskretsen. I tillegg er feilregistreringskretsen| virksom i kombinasjon med en unik kontinuitets-! forriglingskrets som er beskrevet for å sikre bren-neren. Videre er det anordnet en likerettet styrekrets for å opprettholde en stabil lysbue og hindre erosjon av dysen og derav følgende blottlegging av elektroden.
