Working And Operating Principles
Arc Extinguishing Principle
Utilizing the vacuum as an insulating medium, the VS1 vacuum circuit breaker performs arc extinguishing with superior finesse and precision. Through advanced methods, it guarantees reliable functionality.
As the contacts disengage, the arc is compelled to spread and extinguish swiftly, aided by the magnetic field generated within the
vacuum interrupter. This process effectively cools and condenses the arc plasma, ensuring a swift and reliable arc extinguishing process,
resulting in minimal contact wear, thereby guaranteeing consistent, stable, and enduring operation.
Energy Storage
The energy storage system in the VS1 vacuum circuit breaker employs a sophisticated motor-driven mechanism to efficiently wind
Our cutting-edge energy storage springs ensure that once fully charged, the breaker is prepared for flawless operation. This advanced technology
is precisely engineered to ensure reliability, providing stable and rapid energy release, which is critical 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 remarkable speed. This advanced mechanism ensures a rapid and reliable closing action, perfectly suited for a broad range of
applications demanding superior operational performance and reliability.
Opening Operation
During opening operations, the breaker employs the energy stored in the opening springs, released instantaneously upon
receiving an opening command. This rapid energy release forces the contacts apart, effectively interrupting the
current flow and extinguishing the arc within the vacuum interrupter. This vital action ensures safe, efficient, and effective
circuit breaking, offering comprehensive protection for your electrical systems.
Maintenance
Our VS1 vacuum circuit breaker is crafted for effortless maintenance, providing remarkable durability and robust
performance, even in the most challenging operational environments. With routine inspections and minimal maintenance,
you can maintain peak performance, reduce downtime, and ensure the continuous reliability of your electrical
protection systems, optimizing efficiency and operational performance.
