Title (EN) IMPROVED AIR ENTRANCE BUSHING FOR GAS-INSULATED BUS
(FR) TRAVERSEE D"ENTREE D"AIR AMELIORE POUR BUS ISOLE AU GAZ
Abstract: front page image
(EN)An internal shield ring (100) for the air entrance bushing of a gas-insulated bus system tapers inwardly at its free end and has a reduced spacing with respect to the central bushing conductor (75) to increase the dielectric stress between the end (102) of the shield ring and the central bus. This reduces the stress on the external bushing insulation material (51) and thus permits a reduction in the bushing diameter.
(FR)Un anneau de protection interne (100) pour une traversee d"entree d"air d"un systeme a bus isole au gaz presente une extremite libre conique et un espace reduit par rapport au conducteur de traversee centrale (75) pour ameliorer la tension dielectrique entre l"extremite (102) de l"anneau de protection et le bus central. Ceci reduit la contrainte sur le materiau d"isolation de traversee externe (51) et permet donc une reduction du diametre de la traversee.
