Working and Operating Principles
Arc Extinguishing Principle
By harnessing the unparalleled insulating power of vacuum, the VS1 vacuum circuit breaker performs arc extinguishing with remarkable precision and finesse. Utilizing advanced techniques, it guarantees reliable and efficient operation.
As the contacts disengage, the arc is skillfully directed to dissipate swiftly, supported by the magnetic field generated within the
vacuum interrupter. This process effectively cools and condenses the arc plasma, securing a prompt and dependable arc extinguishing process,
which minimizes contact wear and ensures consistent, stable, and trustworthy operation.
Energy Storage
The energy storage system of the VS1 vacuum circuit breaker features a sophisticated motor-driven mechanism that efficiently winds
Our cutting-edge energy storage springs, once fully charged, ensure the breaker is primed for flawless operations. This advanced technology
is meticulously crafted to ensure reliability, providing stable and rapid energy release, crucial for seamless and uninterrupted switching operations.
Closing Operation
Upon receiving a closing command, the stored energy within the closing springs is unleashed, propelling the contacts
together with incredible speed. This sophisticated mechanism ensures a rapid and reliable closing action, perfectly suited for a wide range of
applications where exceptional operational performance and reliability are paramount.
Opening Operation
During opening operations, the breaker utilizes the energy stored in the opening springs, instantly releasing it upon
receiving an opening command. This swift release of energy forces the contacts apart, effectively interrupting the
current flow and extinguishing the arc within the vacuum interrupter. This pivotal action ensures safe, efficient, and effective
circuit breaking, offering comprehensive protection for all your electrical systems.
Maintenance
The design of our VS1 vacuum circuit breaker prioritizes effortless maintenance, offering exceptional durability and robust
performance even in the most challenging operational environments. With regular inspections and minimal maintenance,
it is possible to maintain peak functionality, reduce downtime, and ensure the continuous reliability of your electrical
protection systems, thus optimizing both efficiency and operational performance.
