Working And Operating Principles
Arc Extinguishing Principle
Experience the unparalleled advantages of vacuum technology with the VS1 vacuum circuit breaker, designed to masterfully execute arc extinguishing with unparalleled precision and grace.
As the contacts separate, the arc is effectively forced to spread and extinguish swiftly, driven by the magnetic field dynamically generated within the
vacuum interrupter. This cutting-edge process rapidly cools and condenses the arc plasma, ensuring a swift and dependable arc extinguishing operation,
resulting in minimal wear on the contacts and guaranteeing stable, reliable performance over the long term.
Energy Storage
The VS1 vacuum circuit breaker’s energy storage mechanism is equipped with a motor-driven system that meticulously winds
Our state-of-the-art energy storage springs ensure that, once fully charged, the breaker is perfectly poised for seamless operation. This advanced technology
is expertly crafted to ensure unwavering reliability, delivering a stable and rapid energy release essential for critical switching tasks.
Closing Operation
Upon receiving a closing command, the potent energy stored in the closing springs is unleashed, driving the contacts
together with extraordinary speed. This advanced mechanism ensures a rapid and dependable closing action, ideal for a diverse range of
applications that demand exceptional operational performance and steadfast reliability.
Opening Operation
During opening operations, the breaker utilizes the energy reserved in the opening springs, released instantaneously upon
receiving an opening signal. This rapid discharge of energy propels the contacts apart, effectively breaking the
current flow and extinguishing the arc within the vacuum interrupter. This critical function guarantees safe, efficient, and effective
circuit breaking, ensuring the protection and safety of your electrical infrastructure.
Maintenance
The VS1 vacuum circuit breaker is designed for ease of maintenance, boasting remarkable durability and robust
performance even under the most challenging conditions. With routine inspections and minimal maintenance,
you can sustain optimal functionality, reduce downtime, and secure continuous, reliable electrical
protection, all while enhancing your operational efficiency to new heights.
