Working And Operating Principles
Arc Extinguishing Principle
By harnessing the vacuum as an insulating medium, the VS1 vacuum circuit breaker achieves arc extinguishing with remarkable finesse and precision. Through cutting-edge techniques, it guarantees dependable operation.
As the contacts disengage, the arc is adeptly guided to spread and extinguish swiftly, assisted by the magnetic field generated within the
vacuum interrupter. This method effectively cools and condenses the arc plasma, ensuring a rapid and reliable arc extinguishing process,
resulting in minimal contact wear, ensuring consistent, stable, and dependable operation over time.
Energy Storage
The VS1 vacuum circuit breaker's energy storage system employs a sophisticated motor-driven mechanism to dynamically wind
Our cutting-edge energy storage springs ensure that once charged, the breaker is primed for flawless operation. This innovative technology
is precisely engineered to ensure reliability, providing stable and rapid energy release, essential for seamless switching performance.
Closing Operation
Upon receiving a command to close, the energy stored within the closing springs is unleashed, driving the contacts
together with incredible velocity. This advanced system guarantees a swift and reliable closing action, perfectly suited for a wide range of
applications, ensuring exceptional operational performance and unmatched reliability.
Opening Operation
During opening operations, the breaker uses the energy stored in the opening springs, which is released immediately upon
receiving an opening signal. This swift energy discharge forces the contacts apart, effectively interrupting the
current and extinguishing the arc within the vacuum interrupter. This essential action ensures safe, efficient, and effective
circuit interruption, offering comprehensive protection for your electrical infrastructure.
Maintenance
The VS1 vacuum circuit breaker is crafted for effortless maintenance, offering remarkable durability and robust
performance, even under the most strenuous operational conditions. With routine checks and minimal maintenance,
you can maintain peak performance, minimize downtime, and ensure the continuous reliability of your electrical
protection systems, while maximizing efficiency and enhancing operational performance.
