Working and Operating Principles
Arc Extinguishing Principle
By harnessing the vacuum's insulating prowess, the VS1 vacuum circuit breaker performs arc extinguishing with unmatched precision. Utilizing cutting-edge techniques, it ensures consistent and dependable operation.
When the contacts disengage, the arc is skillfully managed to dissipate and extinguish promptly, facilitated by the magnetic field within the
vacuum interrupter. This process ensures effective cooling and condensation of the arc plasma, guaranteeing a swift, reliable arc extinguishing process,
leading to minimal contact wear and ensuring consistent, stable, and reliable operation in every use.
Energy Storage
The energy storage system in the VS1 vacuum circuit breaker employs an advanced motor-driven mechanism to methodically wind
Our cutting-edge energy storage springs, once fully charged, prepare the breaker for flawless performance. This advanced technology
is precisely crafted to ensure reliability, providing stable, rapid energy release, essential for seamless switching operations.
Closing Operation
Once a closing command is received, the stored energy in the closing springs is unleashed, propelling the contacts
together with remarkable speed. This sophisticated mechanism facilitates a rapid, dependable closing action, designed to excel in a wide range of
applications that demand outstanding operational performance and reliability.
Opening Operation
During opening operations, the breaker taps into the energy stored in the opening springs, released instantly upon
receiving an opening command. This quick energy discharge forces the contacts apart, effectively breaking the
current flow and extinguishing the arc within the vacuum interrupter. This crucial action ensures a secure, efficient, and effective
circuit breaking, offering comprehensive protection and reliability for your electrical systems.
Maintenance
Our VS1 vacuum circuit breaker is crafted for effortless maintenance, providing exceptional durability and robust
performance, even under the most challenging operational conditions. With regular inspections and minimal maintenance,
you can maintain peak functionality, minimize downtime, and ensure the ongoing reliability of your electrical
protection systems, all while optimizing efficiency and enhancing operational performance.
