Abstract

Kraftbelastede høyspenningsledninger (2) er elektrisk brutt ved hjelp av en skilledel (3) som opptar kreftene i ledningene. En strøm-sensor- innretning (4) er koblet elektrisk parallelt med skilledelen (3). Målesignalene blir optisk overført over en lysleder (9), som er innført i en fleksibel isolator (6) med jordpotensial. Fordel: høy jordskjelvssikkerhet, potensialadskillelse.High-voltage high-voltage lines (2) are electrically broken by means of a part (3) which absorbs the forces in the lines. A current sensor device (4) is electrically connected in parallel with the skilled part (3). The measurement signals are optically transmitted over a light conductor (9), which is inserted into a flexible insulator (6) with earth potential. Advantage: high earthquake safety, potential separation.
