Abstract

En anordning for kopling av elekt- riske effekter omfatter minst en elekt- risk koplingsinnretning (5). Denne om- fatter minst ett koplingselement (lOa) som oppviser et elektrodegap (24). Dette kan omdannes mellom elektrisk i hoved- saken isolerende tilstand og elektrisk ledende tilstand. Koplingselementet oppviser videre organer (25) for å brin- ge eller i det minste initiere elektro- degapet eller i det minste en del av dette til å anta elektrisk ledningsevne. Organene (25) for å bringe eller i det minste initiere elektrodegapet til å anta ledningsevne er innrettet til å tilføre energi til elektrodegapet i form av strålingsenergi for ved hjelp av denne strålingsenergi å bringe gapet eller i det minste en del av dette på formen av et plasma.A device for coupling electrical effects comprises at least one electrical coupling device (5). This comprises at least one coupling element (10a) which exhibits an electrode gap (24). This can be converted between electrically essentially insulating state and electrically conductive state. The coupling element further has means (25) for bridging or at least initiating the electrode gap or at least a portion thereof to assume electrical conductivity. The means (25) for causing or at least initiating the electrode gap to assume conductivity are adapted to supply energy to the electrode gap in the form of radiant energy to bring about the gap or at least part thereof in the form of a radiant energy. plasma.
