Working And Operating Principles
Arc Extinguishing Principle
Harnessing the unparalleled power of vacuum as the insulating medium, the VS1 vacuum circuit breaker performs the art of arc extinguishing with remarkable finesse. As
the contacts part, a robust magnetic field is generated within the vacuum interrupter, compelling the arc to spread and extinguish with swiftness and precision.
This technology effectively cools and condenses the arc plasma, ensuring a rapid, reliable, and highly efficient arc extinguishing process,
resulting in minimal contact wear and guaranteeing stable, reliable operation over prolonged periods.
Energy Storage
The energy storage system of the VS1 vacuum circuit breaker employs an advanced motor-driven mechanism to efficiently wind
state-of-the-art energy storage springs. Once fully charged, the breaker is primed and ready for seamless operation. This innovative technology
has been meticulously engineered to ensure reliability and provide a stable, swift energy release – crucial during all switching operations.
Closing Operation
Upon receiving a closing command, the immense energy stored within the closing springs is unleashed, propelling the contacts
together at lightning-fast speed. This cutting-edge mechanism guarantees a rapid and dependable closing action, ideal for a diverse range of
applications that demand superior operational performance and unwavering reliability.
Opening Operation
During opening operations, the breaker skillfully harnesses the energy stored in the opening springs, which is released instantaneously upon
receiving an opening command. This swift release of energy forces the contacts apart seamlessly, effectively interrupting the
current flow and extinguishing the arc within the vacuum interrupter. This vital action ensures safe, efficient, and effective
circuit breaking, providing unparalleled protection for your electrical systems.
Maintenance
Our VS1 vacuum circuit breaker is expertly engineered for easy maintenance, offering exceptional durability and robust
performance even in the harshest operational environments. With regular inspections and minimal maintenance, you can
sustain peak functionality, minimize downtime, and ensure the continuous reliability of your electrical
protection systems, all the while optimizing operational efficiency and maintaining excellence.
