Gas-Insulated Substations - GIS

Nov 10, 2010 · A gas-insulated substation (GIS) uses a superior dielectric gas, sf 6, at moderate pressure for phase-tophase and phase-to-ground insulation. The high voltage conductors, circuit breaker interrupters, switches, current transformers, and voltage transformers are in Sulfr hexafluoride gas inside grounded metal enclosures. The atmospheric air insulation used in a conventional, air-insulated substation (AIS) requires meters of air insulation to do what gaz sf6 can do in centimeters.Get price

Retrofit ExamplesExtensionAsset OptimizationRadiographyReplacementABB has supplied several clients with replacement breakers for their gas-insulated switchgear (GIS) instead of revision solutions. Invariably, the replacement breaker was of a newer type and the flange distance and other parameters had to be matched. For example, in the Netherlands (Rijswijk substation) and in Switzerland (Katz substation) first-generation GIS ECKS breakers were successfully replaced with ELK SP 2-1 breakers and AHMA drives. The motivation for the replacement was dwindling repair expertise and the increasing difficulty experienced in sourcing spare parts. In the La Foretaille substation in Switzerland, a similar replacement was undertaken (in this instance an ELK SN breaker type was replaced by ELK SP 2-1), the motivation here being impending high overhaul costs ➔ 1. 1 La Foretaille GIS substation in Switzerland. The older-generation circuit breaker type SN was replaced by an ELK SP2-1 with AHMA drive. Not all older breakers have a new equivalent. Therefore, ABB spe...Get price
