Working And Operating Principles
Arc Extinguishing Principle
Harnessing the power of the vacuum as an insulating medium, the VS1 vacuum circuit breaker performs arc extinguishing with unmatched finesse and precision. By utilizing advanced techniques, it ensures reliable operation.
As the contacts part, the arc is expertly compelled to spread and extinguish rapidly, aided by the magnetic field generated within the
vacuum interrupter. This process effectively cools and condenses the arc plasma, ensuring a quick and reliable arc extinguishing process,
resulting in minimal contact wear and guaranteeing consistent, stable, and reliable operation.
Energy Storage
The energy storage system of the VS1 vacuum circuit breaker utilizes a sophisticated motor-driven mechanism to efficiently wind
Our state-of-the-art energy storage springs ensure that once fully charged, the breaker is ready for flawless operation. This cutting-edge technology
is meticulously engineered to guarantee reliability, offering 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 incredible speed. This advanced mechanism ensures a rapid and dependable closing action, perfectly equipped for a broad spectrum of
applications requiring exceptional operational performance and reliability.
Opening Operation
During opening operations, the breaker utilizes the energy stored in the opening springs, released instantly upon
receiving an opening command. This swift energy release forces the contacts apart, effectively interrupting the
current flow and extinguishing the arc within the vacuum interrupter. This critical action ensures safe, efficient, and effective
circuit breaking, providing comprehensive protection for your electrical systems.
Maintenance
Our VS1 vacuum circuit breaker is designed for effortless maintenance, delivering exceptional durability and robust
performance, even in the most demanding operational environments. With routine inspections and minimal maintenance,
you can sustain peak functionality, reduce downtime, and ensure the continuous reliability of your electrical
protection systems, while optimizing efficiency and operational performance.
