Generator switchgear HB1

three-phasemedium-voltagevacuum

The 3-phase enclosed switchgear is compact, comprehensive and benefits from 30 years experience in vacuum technology. It incorporates the HB1-C generator circuit-breaker module as its central component. • Rated Current: maximum of 5500 A • Breaking capability: up to 72 kA • Safety: Fully type tested Internal Arc Classification of up to IAC A FLR 63 kA / 0,5 s • Versatility: various types of connections including Insulated Phase Busduct (IPB), Non-Segregated Phase Busbduct (NSPB), Segregated Phase Busbduct (SPB) and cables • Application: indoor and outdoor The HB1 takes power generation continuity to the next level. The HB1 is an advanced generator switchgear designed to protect generators and power transformers. It increases power plant reliability, simplifies operation, and lower costs. It handles currents up to 6,700 A and has a short-circuit rating of up to 72 kA. This system features an air-insulated, metal-enclosed design, integrating a vacuum generator circuit-breaker, main-disconnector, earthing switch, current and voltage transformers, surge arresters, and capacitors. Benefits • Up to 75% OPEX savings thanks to vacuum technology • Maintenance-free with up to 10,000 operating cycles at rated continuous current • High reliability due to spring-operated mechanism stated to be the most reliable* way to operate a GCB, with a service life of up to 10,000 operating cycles • Equipped with sealed-for-life** vacuum interrupter • Flexibility allows the connection of NSPB, cable, and IPB • All components and functions are type-tested and routine-tested delivering a high reliability level
