Abstract

Foreliggende oppfinnelse vedrører en elektrode (1) til bruk som en pol ved overføring av høyspent like- strøm i bakken og/eller i vann. Elektroden (1) er innrettet til å bli plassert i et borehull (10) og omfatter et strømtilførselsorgan (20), samt en struktur (3) som er i ledende kontakt med strømtil- førselsorganet (2), idet strukturen (3) er forsynt med en aktiv overflate (3) av et elektrokjemisk aktivt belegg (4). Strukturen (3) er fortrinnsvis en foldet eller korrigert struktur, for oppnåelse av en utvidet aktiv flate. Oppfinnelsen vedrører også en prosess for overføring av høyspent likestrøm ved bruk av en kabel og et par av elektrodeanordninger, hvorved hver anordning omfatter en eller flere elek- troder, og hvorved en elektrodeanordning virker som anode og den andre anordning som katode. Elektrodene er senket ned i sine respektive borehull, som er tildannet ved endepunkter for en avstand via hvilken strøm skal overføres, og ned til et lag i bakken med gode ledende egenskaper, og for å lede strømmen i nevnte lag og i kabelen.The present invention relates to an electrode (1) for use as a pole in the transmission of high voltage direct current in the ground and / or in water. The electrode (1) is arranged to be placed in a borehole (10) and comprises a current supply means (20), as well as a structure (3) in conductive contact with the current supply means (2), the structure (3) being provided. with an active surface (3) of an electrochemically active coating (4). The structure (3) is preferably a folded or corrected structure, to obtain an extended active surface. The invention also relates to a process for transmitting high voltage direct current using a cable and a pair of electrode devices, each device comprising one or more electrodes, whereby one electrode device acts as anode and the other device as cathode. The electrodes are lowered into their respective boreholes, which are formed at end points for a distance through which current is to be transmitted, and down to a layer in the ground with good conductive properties, and to conduct the current in said layer and in the cable.
