Working And Operating Principles
Arc Extinguishing Principle
Harnessing the unparalleled power of vacuum as the insulating medium, the VS1 vacuum circuit breaker executes arc extinguishing with precision and finesse. As
the contacts part, the arc is ingeniously compelled to spread and extinguish swiftly, assisted by the magnetic field generated within the
vacuum interrupter. This innovative process effectively cools and condenses the arc plasma, ensuring a rapid and reliable arc extinguishing process,
resulting in minimal contact wear and assuring stable, efficient, and highly reliable operation.
Energy Storage
The energy storage system of the VS1 vacuum circuit breaker employs a robust motor-driven mechanism to efficiently wind
Our advanced energy storage springs ensure that, once fully charged, the breaker is primed and ready for seamless operation. This cutting-edge technology
has been meticulously crafted to guarantee reliability, delivering stable and swift energy release that is crucial during switching operations.
Closing Operation
Upon receiving a closing command, the energy stored within the closing springs is unleashed, propelling the contacts
together with lightning-fast speed. This state-of-the-art mechanism ensures a rapid and dependable closing action, perfectly suited for an expansive array of
applications that demand superior operational performance and unwavering reliability.
Opening Operation
In the opening operations, the breaker expertly harnesses the energy stored in the opening springs, which is released instantly upon
receiving an opening command. This swift release of energy decisively forces the contacts apart, effectively interrupting the
current flow and extinguishing the arc within the vacuum interrupter. This essential action ensures safe, efficient, and proficient
circuit breaking, safeguarding your electrical systems with assurance and reliability.
Maintenance
Our VS1 vacuum circuit breaker is engineered for simplicity in maintenance, offering exceptional durability and robust
performance even in the harshest of operational environments. With regular inspections and minimal maintenance,
you can sustain peak functionality, minimize downtime, and ensure the continuous reliability of your electrical
protection systems, all while optimizing operational efficiency and effectiveness.
