Working And Operating Principles
Arc Extinguishing Principle
Expertly leveraging the vacuum as an insulating medium, the VS1 vacuum circuit breaker executes arc extinguishing with unparalleled finesse and precision. Utilizing cutting-edge techniques, it ensures steadfast and dependable operation.
As the contacts separate, the arc is skillfully coerced to disperse and extinguish swiftly, aided by the magnetic field generated within the
vacuum interrupter. This process proficiently cools and condenses the arc plasma, ensuring a swift and reliable arc extinguishing process,
leading to minimal contact wear and ensuring consistent, stable, and reliable operation over time.
Energy Storage
The energy storage system of the VS1 vacuum circuit breaker employs an advanced motor-driven mechanism to efficiently tension
Our cutting-edge energy storage springs ensure the breaker is poised for flawless operation once fully charged. This state-of-the-art technology
is precisely engineered to assure reliability, providing stable and rapid energy release, essential for smooth switching operations.
Closing Operation
Upon receiving a closing command, the energy stored within the closing springs is rapidly released, propelling the contacts
together with remarkable agility. This advanced mechanism guarantees a rapid and reliable closing action, perfectly suited for a range of
applications that demand exceptional operational performance and steadfast reliability.
Opening Operation
During opening operations, the breaker exploits the energy stored in the opening springs, released instantaneously upon
receiving an opening command. This swift energy discharge forces the contacts apart, effectively interrupting the
current flow and successfully extinguishing the arc within the vacuum interrupter. This vital action guarantees safe, efficient, and effective
circuit breaking, offering comprehensive protection for your electrical systems.
Maintenance
Our VS1 vacuum circuit breaker is engineered for effortless maintenance, ensuring exceptional longevity and robust
performance, even under the most demanding operational conditions. With routine inspections and minimal maintenance,
you can maintain peak functionality, reduce downtime, and ensure the continuous reliability of your electrical
protection systems, all while optimizing efficiency and operational performance.
