Working And Operating Principles
Arc Extinguishing Principle
Harnessing the exceptional power of vacuum as its insulating medium, the VS1 vacuum circuit breaker performs arc extinguishing with unparalleled finesse and precision. As
the contacts part, the arc is ingeniously compelled to spread and extinguish with exceptional swiftness, bolstered by the magnetic field strategically generated within the
vacuum interrupter. This innovative technology effectively cools and condenses the arc plasma, ensuring a rapid and highly reliable arc extinguishing process,
resulting in minimal contact wear and assuring a consistently stable and reliable operation every time.
Energy Storage
The VS1 vacuum circuit breaker's energy storage system employs a cutting-edge motor-driven mechanism that efficiently winds,
Our state-of-the-art energy storage springs ensure that, once fully charged, the breaker is impeccably primed and ready for flawless operation. This pioneering technology
has been meticulously designed to guarantee unmatched reliability, providing stable and swift energy release that is absolutely crucial during switching operations.
Closing Operation
Upon receiving a closing command, the energy stored within the closing springs is dynamically unleashed, propelling the contacts
together with lightning-fast agility. This state-of-the-art mechanism guarantees a rapid, dependable closing action, perfectly engineered for a diverse range of
applications demanding superior operational performance and unwavering reliability.
Opening Operation
During opening operations, the breaker deftly harnesses the energy stored in the opening springs, which is instantaneously released upon
receiving an opening command. This swift release of energy forces the contacts apart with precision, effectively interrupting the
current flow and extinguishing the arc within the advanced vacuum interrupter. This critical action ensures safe, efficient, and highly effective
circuit breaking, safeguarding your invaluable electrical systems with absolute assurance.
Maintenance
Our VS1 vacuum circuit breaker is meticulously engineered for simplicity in maintenance, providing exceptional durability and robust
performance, even in the most challenging operational environments. With regular inspections and minimal maintenance,
you can sustain peak functionality, significantly minimize downtime, and ensure the continuous reliability of your electrical
protection systems, all while optimizing operational efficiency to extraordinary levels.
