Working And Operating Principles
Arc Extinguishing Principle
Harnessing the unmatched power of vacuum as the insulating medium, the VS1 vacuum circuit breaker executes arc extinguishing with remarkable finesse. As
the contacts separate, the arc is compelled to spread and extinguish swiftly, aided by the expertly generated magnetic field within the
vacuum interrupter. This masterfully cools and condenses the arc plasma, ensuring a rapid and reliable arc extinguishing process,
resulting in minimal contact wear and assuring consistently stable and reliable operation.
Energy Storage
The energy storage system of the VS1 vacuum circuit breaker is driven by an efficient motor-driven mechanism that expertly
Our state-of-the-art energy storage springs ensure that, once fully charged, the breaker is primed and ready for flawless operation. This cutting-edge technology
is meticulously designed to guarantee reliability, offering stable and swift energy release, which is crucial during critical 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 precision. This state-of-the-art mechanism guarantees 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 opening operations, the breaker expertly leverages the energy stored in the opening springs, which is released instantly upon
receiving an opening command. This swift release of energy effectively forces the contacts apart, interrupting the
current flow and extinguishing the arc within the vacuum interrupter. This essential action ensures safe, efficient, and effective
circuit breaking, fully safeguarding your valuable electrical systems.
Maintenance
Our VS1 vacuum circuit breaker is ingeniously engineered for simplicity in maintenance, offering outstanding durability and robust
performance even in the most challenging 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 performance.
