Working And Operating Principles
Arc Extinguishing Principle
Harnessing the power of vacuum as the insulating medium, the VS1 vacuum circuit breaker executes arc extinguishing with finesse. As
the contacts part, the arc is compelled to spread and extinguish swiftly, aided by the magnetic field generated within the
vacuum interrupter. This effectively cools and condenses the arc plasma, ensuring a rapid and reliable arc extinguishing process,
resulting in minimal contact wear and assuring stable and reliable operation.
Energy Storage
The energy storage system of the VS1 vacuum circuit breaker employs a motor-driven mechanism to efficiently wind
Our advanced energy storage springs ensure that, once fully charged, the breaker is primed and ready for flawless operation. This technology
has been meticulously designed to guarantee reliability, providing stable and swift energy release that is crucial during switching operations.
Closing Operation
When a closing command is received, the energy stored within the closing springs is unleashed, propelling the contacts
together with lightning-fast speed. This state-of-the-art mechanism guarantees a rapid and dependable closing action, perfectly suited for a wide range of
applications that require superior operational performance and reliability.
Opening Operation
In opening operations, the breaker harnesses the energy stored in the opening springs, which is released instantly upon
receiving an opening command. This swift release of energy 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, safeguarding your electrical systems.
Maintenance
Our VS1 vacuum circuit breaker is engineered for simplicity in maintenance, offering exceptional durability and robust
performance even in the most demanding operational environments. With regular inspections and minimal maintenance,
you can maintain peak functionality, minimize downtime, and ensure the continuous reliability of your electrical
protection systems, all while optimizing operational efficiency.
