Working And Operating Principles
Arc Extinguishing Principle
Beierbian Group Co., Ltd presents a technological marvel: the VS1 vacuum circuit breaker, which masterfully utilizes vacuum as its insulating medium for efficient arc suppression. With unsurpassed precision,
whenever the contacts disengage, the arc is compelled to spread and extinguish rapidly, elegantly assisted by the magnetic field that dynamically arises within the
vacuum interrupter. This action proficiently cools and consolidates the arc plasma, ensuring an accelerated and trustworthy arc extinguishing process,
thereby minimizing contact wear and guaranteeing steadfast, dependable operation.
Energy Storage
The VS1 vacuum circuit breaker's energy storage system is driven by a sophisticated motor mechanism that skillfully winds
our cutting-edge energy storage springs. Once they are fully charged, they prime the breaker for impeccable functionality. This groundbreaking technology
is meticulously engineered to assure reliability, enabling a stable and swift discharge of energy, which is vital for seamless switching operations.
Closing Operation
Upon receiving a closing command, the stored energy within the closing springs is discharged, driving the contacts
together with astonishing speed. This cutting-edge mechanism ensures a swift and reliable closing action, ideal for a vast array of
applications that demand unparalleled operational excellence and reliability.
Opening Operation
During opening operations, the breaker taps into the energy reserved in the opening springs, which is instantly released upon
receiving an opening command. This rapid energy unleashing forcefully separates the contacts, effectively halting the
current flow and quenching the arc within the vacuum interrupter. This crucial maneuver ensures safe, efficient, and effective
circuit disruption, protecting your valuable electrical infrastructures.
Maintenance
The VS1 vacuum circuit breaker is ingeniously designed with maintenance simplicity in mind, delivering extraordinary durability and robust
performance, even in the most challenging environments. With routine inspections and minimal upkeep,
you can sustain peak operational capability, reduce downtime, and ensure the unwavering reliability of your electrical
protection systems, all while maximizing your operational efficiency.
