Abstract

på grunn av den forholdsvis langsomme drift av hovedkoblingsstiften (3) i en skillebryter (1) er det vanlig å anordne en i det indre av hovedkoblingsstiften (3) forekommende fjærbelastet hjelpe- koblingsstift (7) som i likhet med hovedkoblingsstiften (3) kommer til. anlegg på en motkontakt (28) og ved begynnelse av utkoblingsbevegelsen forblir der inntil den ved en fjær (8) , etter frigivelse ved en mekanisk styring, (14) føres tilbake til hvilestillingen med en i forhold til bevegelsen av hovedkoblingsstiften (3) større has- tighet. Den mekaniske styring (14) inneholder en dreibart lagret, i hvilestillingen selvlåsende løftearm- ' anordning (15) som fastholder hjelpe- koblingsstiften (7) inntil den frigis ved en til hovedkoblingsstiften forbundet føringsflate (21) . Også hjelpekontakten (28) i hovedkoblingsstiften (7) er fjærbelastet og følger noe etter denne etter utløsning og opprettholder dertil potensialforbindelsen. Skillebryteren er egnet til bruk i metallkapslede, trykkgassisolerte høyspenningsapparat- anlegg som skal koble magnetiserings- strømmer i transformatorer.due to the relatively slow operation of the main coupling pin (3) in a disconnect switch (1), it is customary to provide a spring-loaded auxiliary coupling pin (7) located within the interior of the main coupling pin (3) which, like the main coupling pin (3), arrives . abutment on a counter-contact (28) and at the beginning of the switch-off movement remains there until it is returned to a resting position by a spring (8), after release by a mechanical control, (14) with a greater relative to the movement of the main switch-pin (3). - tightness. The mechanical guide (14) includes a pivotally mounted, self-locking lifting arm (15) which retains the auxiliary coupling pin (7) until it is released by a guide surface (21) connected to the main coupling pin. Also the auxiliary contact (28) in the main coupling pin (7) is spring loaded and follows somewhat after release and maintains the potential connection. The disconnect switch is suitable for use in metal-enclosed, high-pressure insulated high-voltage apparatus which is intended to connect magnetizing currents in transformers.
