Working and Operating Principles
Arc Extinguishing Principle
By harnessing the powerful insulating properties of vacuum technology, the VS1 vacuum circuit breaker executes arc extinguishing with exceptional precision. Its advanced design ensures consistent and reliable operation through innovative techniques.
As the contacts disengage, the arc is expertly controlled and swiftly extinguished, facilitated by the magnetic field generated within the
vacuum interrupter. This expertly managed process efficiently cools and condenses the arc plasma, ensuring a rapid and reliable arc extinguishing process,
resulting in minimal wear on contacts, thereby guaranteeing consistently stable and dependable operation over time.
Energy Storage
The energy storage system of the VS1 vacuum circuit breaker employs an advanced motor-driven mechanism to expertly wind
Our cutting-edge energy storage springs are engineered to perfection, ensuring that once fully charged, the breaker is primed for flawless operation. This state-of-the-art technology
is designed to deliver reliability and offers a stable, rapid energy release, which is essential for smooth and seamless switching operations.
Closing Operation
Upon receiving the closing command, the energy stored within the closing springs is unleashed, moving the contacts
together with incredible speed. This sophisticated mechanism ensures a quick and reliable closing action, tailored for a wide array of
applications requiring superior operational performance and steadfast reliability.
Opening Operation
During opening operations, the breaker taps into the energy stored within the opening springs, released instantly upon
receiving an opening command. This rapid energy discharge drives the contacts apart, effectively interrupting the
current flow and extinguishing the arc within the vacuum interrupter. This essential process ensures safe and efficient
circuit breaking, offering comprehensive protection for your electrical infrastructure.
Maintenance
Our VS1 vacuum circuit breaker is engineered for hassle-free maintenance, providing exceptional durability and strong
performance in even the most rigorous operational settings. With regular inspections and minimal upkeep,
you maintain peak functionality, reduce downtime, and ensure the continuous reliability of your electrical
protection systems, all while optimizing overall efficiency and operational performance.
