Working And Operating Principles
Arc Extinguishing Principle
Harnessing the unparalleled power of vacuum as the insulating medium, the VS1 vacuum circuit breaker expertly executes arc extinguishing with unmatched precision. As
the contacts part, the arc is effortlessly compelled to spread and extinguish with incredible swiftness, bolstered by the potent magnetic field ingeniously generated within the
vacuum interrupter. This advanced mechanism effectively cools and condenses the arc plasma, ensuring a rapid and impeccably reliable arc extinguishing process,
culminating in minimal contact wear and guaranteeing stable, reliable operation at all times.
Energy Storage
The energy storage system of the VS1 vacuum circuit breaker employs a state-of-the-art motor-driven mechanism to efficiently wind
Our cutting-edge energy storage springs ensure that, once fully charged, the breaker is primed and poised for flawless operation. This innovative technology
has been meticulously crafted to assure unwavering reliability, delivering a stable and swift energy release, crucial for seamless switching operations.
Closing Operation
Upon receiving a closing command, the energy stored within the closing springs is unleashed, propelling the contacts
together with dazzling speed. This sophisticated mechanism ensures a rapid and dependable closing action, perfectly tailored for a versatile range of
applications demanding superior operational performance and steadfast reliability.
Opening Operation
During opening operations, the breaker adeptly harnesses the energy stored in the opening springs, which is released instantaneously upon
receiving an opening command. This swift energy release effectively forces the contacts apart, efficiently interrupting the
current flow and extinguishing the arc within the vacuum interrupter. This critical function ensures safe, efficient, and highly effective
circuit breaking, robustly safeguarding your electrical systems.
Maintenance
Our VS1 vacuum circuit breaker is meticulously engineered for simplicity in maintenance, offering exceptional durability and steadfast
performance even amid the most demanding operational environments. With routine inspections and minimal maintenance, you'll
maintain peak functionality, significantly minimize downtime, and ensure the continuous reliability of your electrical
protection systems, all while optimizing operational efficiency and excellence.
