Working And Operating Principles
Arc Extinguishing Principle
Leveraging the vacuum as a supreme insulating medium, the VS1 vacuum circuit breaker exhibits extraordinary finesse in arc extinguishing. Utilizing cutting-edge techniques, it achieves reliable operation with precision and assurance, setting a new standard for circuit breaker performance.
As the contacts disengage, the arc is expertly stretched and swiftly extinguished, facilitated by the magnetic field generated within the
vacuum interrupter. This seamless process efficiently cools and condenses the arc plasma, leading to a rapid and reliable arc extinguishing process,
minimizing contact wear while ensuring continuous, stable, and reliable operation, thus safeguarding system integrity.
Energy Storage
Boasting a sophisticated motor-driven mechanism, the energy storage system in the VS1 vacuum circuit breaker adeptly winds the springs,
Our revolutionary energy storage springs, once fully charged, prime the breaker for impeccable operation. This state-of-the-art technology
is engineered with precision to ensure reliability, offering a dependable and swift release of energy, essential for seamless and efficient switching operations.
Closing Operation
Upon receiving a closing command, the energy stored in the closing springs is dynamically released, propelling the contacts
together with phenomenal speed. This cutting-edge mechanism ensures a rapid and reliable closing action, perfectly suited for a diverse range of
applications demanding superior operational performance and dependability.
Opening Operation
During opening operations, the stored energy in the opening springs is instantly unleashed upon
receiving an opening command. This swift release of energy effectively separates the contacts, promptly interrupting the
current flow and extinguishing the arc within the vacuum interrupter. This crucial operation guarantees safe, efficient, and effective
circuit breaking, ensuring comprehensive protection for your electrical systems and peace of mind.
Maintenance
The VS1 vacuum circuit breaker is ingeniously designed for effortless maintenance, showcasing remarkable durability and robust
performance, even under the most demanding operating conditions. With regular inspections and minimal maintenance,
you can maintain peak functionality, minimize downtime, and ensure the enduring reliability of your electrical
protection systems, optimizing efficiency and operational performance for continuous peace of mind.
