Working And Operating Principles
Arc Extinguishing Principle
By harnessing the exceptional insulating capabilities of vacuum technology, the VS1 vacuum circuit breaker performs arc extinguishing with unparalleled precision. Utilizing advanced techniques, it guarantees steadfast and reliable operation, marking a new era in circuit breaker technology.
As the contacts diverge, the arc is expertly manipulated to spread and extinguish with remarkable swiftness, powered by the magnetic field generated within the
vacuum interrupter. This ingenious process effectively cools and condenses the arc plasma, ensuring a rapid and reliable extinguishing process,
resulting in minimized contact wear and ensuring consistent, stable, and reliable operation over time.
Energy Storage
The energy storage system of the VS1 vacuum circuit breaker is equipped with a sophisticated motor-driven mechanism that efficiently winds
Our cutting-edge energy storage springs are designed to ensure that once fully charged, the breaker operates flawlessly. This innovative technology
is meticulously crafted to guarantee reliability, offering stable and swift energy release, which is essential for seamless and efficient switching operations.
Closing Operation
Upon receiving a closing command, the stored energy in the closing springs is released with precision, propelling the contacts
together with remarkable speed. This sophisticated mechanism guarantees a rapid and dependable closing action, perfectly suited for a wide array of
applications that demand exceptional operational performance and unwavering reliability, ensuring optimum functionality.
Opening Operation
During opening operations, the breaker utilizes the energy stored in the opening springs, which is released instantly upon
receiving an opening command. This rapid energy release efficiently forces the contacts apart, effectively halting the
current flow and extinguishing the arc within the vacuum interrupter. This vital action ensures safe, efficient, and effective
circuit breaking, offering comprehensive protection for your electrical systems, safeguarding their integrity.
Maintenance
The VS1 vacuum circuit breaker is engineered for effortless maintenance, offering exceptional durability and robust
performance, even under the most demanding operational conditions. With routine inspections and minimal maintenance,
you can maintain peak functionality, minimize downtime, and ensure the continuous reliability of your electrical
protection systems, while optimizing efficiency and enhancing operational performance.
