Abstract
En elektrisk koblingsanordning har et par hovedelektroder (7,20) som er innbyrdes^Tcontakt i en første PA-stilling, en lysbueelektrode (8) som er elektrisk koblet til og stivt for- bundet med en av hovedelektrodene samt et bærende kontakt- element (31) som er elektrisk koblet til og fjærende montert i forhold til den annen hovedelektrode. I drift kan hovedelektrodene (7,20) bevege seg i forhold til hverandre fra den første PÅ-stilling gjennom en annen mellom- stilling til en tredje AV-stilling, hvor det fjærende kontakt- element (31) i mellomstillingen befinner seg i kontakt med lysbueelektroden (8), mens første hovedelektrode (7) og lysbueelektroden (8) i AV-stillingen er ute av kontakt med den annen elektrode (20) og det fjærende kontaktelement (31). Bryteranordningen er anordnet slik at hovedelektrodene kan forskyves bort fra den tredje stilling, nemlig AV-stillingen til den første PÅ-stillingen uten at det fjærende kontaktelement kommer i kontakt med lysbueelektroden.An electrical coupling device has a pair of main electrodes (7,20) interconnected in a first PA position, an arc electrode (8) electrically connected and rigidly connected to one of the main electrodes, and a supporting contact element ( 31) which is electrically connected and resiliently mounted relative to the other main electrode. In operation, the main electrodes (7,20) can move relative to each other from the first ON position through a second intermediate position to a third AV position, where the resilient contact element (31) in the intermediate position is in contact with the the arc electrode (8), while the first main electrode (7) and the arc electrode (8) in the AV position are out of contact with the second electrode (20) and the resilient contact element (31). The switching device is arranged so that the main electrodes can be moved away from the third position, namely the AV position of the first ON position without the resilient contact element coming into contact with the arc electrode.
