Interrupting Chamber
GE Vernovacircuit breakers use a proven innovative interrupter design with self-blast technology that significantly reduces the mechanical energy required to clear short-circuit currents. The interrupter design uses the arc energy to generate gas compression for efficient quenching of the arc itself.
As a member of the puffer family, the interrupter has two gas volumes within the chamber, one mechanical and one thermal. The design of the interrupter ensures that the circuit breaker will interrupt short-circuit fault current from low level faults to the full nameplate rating.
Spring-Spring-Operated Mechanism
GE Vernova has been developing and manufacturing spring-spring-operated mechanisms since 1938. The most recent state-of-the art evolution for these mechanisms is the FK3 range, which is used for all GE Vernova high voltage switchgear applications including dead tank, live tank, generator circuit breakers, GIS and hybrid solutions. Over 300,000 FK3 mechanisms are in operation worldwide. The FK3 low energy spring-spring mechanism provides the highest level of reliability with Class M2 performance for 10,000 no-load close-open operations without the need for routine maintenance. With a spring-spring-operated mechanism there are no pneumatics or hydraulics, ensuring safe, reliable and maintenance-free operation for the normal circuit breaker service life of 50 years or more.
CBWatch3 is a universal and compact device suitable for any kind of high voltage circuit breaker.
