Working And Operating Principles
Arc Extinguishing Principle
The VS1 vacuum circuit breaker takes the art of arc extinguishing to new heights by harnessing the vacuum as an insulating medium. Through sophisticated techniques, it guarantees reliable and precision-controlled operation, ensuring that every use is flawless.
When the contacts separate, the expertly managed arc is swiftly driven to dissipate, aided by the intricate magnetic field generated within the
vacuum interrupter. This process not only cools and condenses the arc plasma efficiently but also guarantees a rapid and dependable arc extinguishing process,
resulting in significantly reduced contact wear. This ensures consistent, stable, and reliable operation, every time.
Energy Storage
The VS1's energy storage system boasts a cutting-edge motor-driven mechanism that expertly winds
Our advanced energy storage springs are designed to ensure readiness for flawless operation once fully charged. This cutting-edge solution
is engineered with meticulous precision to promise absolute reliability, providing stable and rapid energy release, essential for seamless switching operations.
Closing Operation
On receiving a closing command, the energy stored within the sophisticated closing springs is released, driving the contacts
together with remarkable speed. This advanced mechanism empowers a rapid and dependable closing action, perfectly tailored for a wide range of
applications that demand superior operational performance and unwavering reliability.
Opening Operation
During the opening operations, the breaker utilizes the stored energy in the opening springs, which is released instantly upon
receiving an opening command. This rapid energy discharge effectively forces the contacts apart, efficiently interrupting the
current flow and extinguishing the arc within the vacuum interrupter. This crucial action ensures safe, efficient, and effective
circuit breaking, offering comprehensive protection for your electrical systems, guaranteeing peace of mind.
Maintenance
Our VS1 vacuum circuit breaker is engineered for effortless maintenance, combining exceptional durability with robust
performance, even in the most challenging operational conditions. With routine inspections and minimal maintenance needed,
you can maintain peak functionality, minimize downtime, and ensure the ongoing reliability of your electrical
protection systems, while optimizing both efficiency and operational performance to meet the highest standards.
