SecoVac* R Retrofill Vacuum Circuit Breaker
The GE SecoVac* R Retrofill vacuum circuit breaker is designed to easily replace vacuum circuit breakers in existing switchgear in systems up to 15kV maximum rated voltage. It is a streamlined solution to update legacy circuit breakers with smart design features such as a simplified mechanism, which reduces maintenance time for customers.
It is designed and tested to the requirements of IEEE C37.04, C37.06, C37.20.2, C37.09, including continuous current, short circuit and short-time current, capacitive switching and endurance.
Manufactured in accordance with the highest quality standards, the SecoVac R Retrofill is a highly reliable and compact system. This advanced design demonstrates GE’s engineering strength in core technologies, combining mechanism modularity design, vacuum arc control, the latest circuit breaker and insulation technology.
SecoVac R Retrofill vacuum circuit breakers are rated for 5kV - 15kV, 1200A - 2000A, 31.5kAIC - 40kAIC, 50Hz/60Hz.
The front panel provides a metal barrier between the breaker compartment and the secondary device compartment. It includes operating controls and indicators such as TRIP button, CLOSE button, OPEN/CLOSE indicator, CHARGE/ DISCHARGE indicator, OPERATIONS counter and a handle for manually charging the breaker.
The primary disconnect finger set is rugged and easy to inspect. Designed for optimum contact, it is built of silver-plated copper and tested for continuous and short time current. These disconnects provide proper contact integrity throughout the life of the gear for the critical primary disconnect function.
The breaker operating mechanism is accessible at the front panel allowing for easy access without removing then breaker from the compartment or turning the breaker on its side. All the individual mechanical parts of the operating mechanism are integrated into replaceable modules. This design requires no mechanical adjustment after replacement, thereby shortening lead-time and reducing operation and maintenance cost.
For personnel safety, SecoVac R Retrofill is designed with a number of mechanical and electrical interlocks. For example, breaker contacts must be open before the breaker can be moved to or from the CONNECT position. A positive mechanical stop is provided when the breaker reaches the CONNECT or TEST/ DISCONNECT positions.
