Working And Operating Principles
Arc Extinguishing Principle
Harness the exceptional insulating power of the vacuum with the VS1 vacuum circuit breaker, designed to perform arc extinguishing with extraordinary finesse and precision. Utilizing cutting-edge techniques, it guarantees reliable and consistent operation.
As the contacts separate, the arc is expertly managed to spread and extinguish rapidly, aided by the sophisticated magnetic field generated within the
vacuum interrupter. This process effectively cools and condenses the arc plasma, ensuring a swift and reliable arc extinguishing process,
resulting in minimal contact wear and ensuring consistent, stable, and dependable operation.
Energy Storage
The VS1 vacuum circuit breaker boasts an advanced motor-driven energy storage system, efficiently winding
Our cutting-edge energy storage springs, once fully charged, prepare the breaker for flawless operation. This state-of-the-art technology
is meticulously crafted to ensure consistent reliability, offering stable and rapid energy release, crucial for seamless switching operations.
Closing Operation
Upon receiving a closing command, the stored energy within the closing springs is released, driving the contacts
together with remarkable speed. This advanced mechanism ensures a rapid and dependable closing action, perfectly suited for a wide range of
applications demanding exceptional operational performance and reliability.
Opening Operation
During opening operations, the breaker leverages the energy stored in the opening springs, released with precision upon
receiving an opening command. This swift energy release forces the contacts to part, effectively interrupting the
current flow and extinguishing the arc within the vacuum interrupter. This decisive action ensures safe, efficient, and effective
circuit breaking, providing comprehensive and reliable protection for your electrical systems.
Maintenance
The VS1 vacuum circuit breaker is engineered for effortless maintenance, boasting exceptional durability and robust
performance, even in the most strenuous operational environments. With routine inspections and minimal maintenance,
you can maintain peak functionality, reduce downtime, and ensure the continuous dependability of your electrical
protection systems, while maximizing efficiency and operational performance.
