Working And Operating Principles
Arc Extinguishing Principle
Harnessing the immense power of vacuum as an unparalleled insulating medium, the VS1 vacuum circuit breaker conducts arc extinguishing with exquisite precision and finesse. As
the contacts part, the arc is masterfully compelled to spread and extinguish swiftly, aided by the robust magnetic field generated within the
vacuum interrupter. This innovative process effectively cools and condenses the arc plasma, ensuring a rapid, seamless, and utterly reliable arc extinguishing process,
resulting in minimal contact wear while assuring stable, trustworthy, and consistent operation.
Energy Storage
The cutting-edge energy storage system of the VS1 vacuum circuit breaker employs a sophisticated motor-driven mechanism to efficiently wind
Our state-of-the-art energy storage springs ensure that, once fully charged, the breaker stands primed and poised for flawless, uninterrupted operation. This advanced technology
has been meticulously crafted to guarantee unwavering reliability, providing consistently stable and swift energy release critical during high-stakes switching operations.
Closing Operation
Upon receiving a closing command, the stored energy within the closing springs is unleashed with precision, propelling the contacts
together with unparalleled, lightning-fast speed. This pioneering mechanism guarantees a rapid and dependable closing action, impeccably suited for a comprehensive range of
applications demanding superior operational performance and unwavering reliability.
Opening Operation
During opening operations, the breaker masterfully harnesses the energy stored in the opening springs, which is released instantly upon
receiving an opening command. This swift, decisive release of energy forces the contacts apart, effectively interrupting the
current flow and extinguishing the arc within the vacuum interrupter. This crucial action guarantees safe, efficient, and effective
circuit breaking, safeguarding the integrity and reliability of your electrical systems.
Maintenance
Our VS1 vacuum circuit breaker is engineered for effortless simplicity in maintenance, offering unprecedented durability and robust
performance even in the most demanding operational environments. With routine inspections and minimal maintenance,
you can sustain peak functionality, minimize costly downtime, and ensure the continuous, unwavering reliability of your electrical
protection systems, all while maximizing operational efficiency and performance.
