Working And Operating Principles
Arc Extinguishing Principle
Utilizing the vacuum as a superior insulating medium, the VS1 vacuum circuit breaker executes arc extinguishing with precision and elegance. With advanced techniques, it offers operation reliability like none other.
As the contacts part, the arc is expertly 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, enabling a quick and reliable arc extinguishing process,
leading to minimal contact wear and ensuring consistent, stable, and reliable operation.
Energy Storage
The energy storage system of the VS1 vacuum circuit breaker employs a highly advanced motor-driven mechanism to efficiently wind
Our cutting-edge energy storage springs guarantee that once fully charged, the breaker is primed for impeccable operation. This modern technology
is engineered with precision to ensure reliability, offering stable and rapid energy release, which is crucial for seamless switching operations.
Closing Operation
Upon receiving a closing command, the energy stored within the closing springs is released, driving the contacts
together with remarkable speed. This sophisticated mechanism ensures a rapid and reliable closing action, adeptly handling a wide range of
applications that demand exceptional operational performance and reliability.
Opening Operation
During opening operations, the breaker leverages the energy stored in the opening springs, released instantaneously upon
receiving an opening command. This swift energy discharge forces the contacts apart, effectively cutting the
current flow and extinguishing the arc within the vacuum interrupter. This critical action ensures safe, efficient, and effective
circuit breaking, offering comprehensive protection for your electrical systems.
Maintenance
The VS1 vacuum circuit breaker is designed for effortless maintenance, featuring exceptional durability and robust
performance even in the most rigorous operational environments. With regular inspections and minimal maintenance,
you can maintain peak functionality, reduce downtime, and ensure the continuous reliability of your electrical
protection systems while optimizing efficiency and operational performance.
