Aiming to reduce greenhouse gas emissions, Mitsubishi Electric promotes the wide spread adoption of 70 kV-class cubicle-type gas-insulated switchgear (C-GIS) equipped with a vacuum circuit breaker, and that uses no SF 6 gas thanks to a dry-air insulation technique. In addition, a spring-operated mechanism is used instead of the conventional hydraulic operation mechanism, which greatly reduces maintenance work.Get price

Applying Vacuum Generator Circuit Breakers at Hydropower

Special Requirements in Hydropower and Pumped-Storage UnitsTechnological AdvancementsAdvantages of This TechnologyEnvironmental ImpactVacuum Switching Technology For Short-Circuit Currents Up to 100 KaSummaryGoldisthal Case StudyDue to their technical and physical characteristics, hydropower plants place different demands on generator switchgear than other types of power plants. For instance, hydro generators normally rotate at about 300 to 400 revolutions per minute, which is significantly slower than coal- or gas-fired power plants. This has a direct impact on the short-circuit currents fed by the generator and results in a heavier load on the breaker during the switching process. In addition, hydropower plants often use a three-winding transformer instead of the typical two-winding transformer to connect the high-voltage network. This results in a high DC component from a system source fault, which in turn necessitates a higher switching capacity. Another special requirement is for pumped-storage hydro plants. In these facilities, the circuit breakers must perform multiple load switching or rated current switching operations per day, compared with other power plants where typically no-load switching is p...Get price
