Working And Operating Principles
Arc Extinguishing Principle
Harnessing the immense power of vacuum as the insulating medium, the VS1 vacuum circuit breaker performs arc extinguishing with remarkable precision and elegance. As
the contacts part, the arc is compelled to spread and extinguish swiftly, expertly aided by the magnetic field generated within the
vacuum interrupter. This mechanism effectively cools and condenses the arc plasma, ensuring a rapid and reliable extinguishing process,
resulting in minimal contact wear while assuring stable and dependable operation at all times.
Energy Storage
The cutting-edge energy storage system in the VS1 vacuum circuit breaker employs a motor-driven mechanism to efficiently wind up
Our advanced energy storage springs, ensuring that once fully charged, the breaker is primed and ready for an impeccable operation. This technology
is meticulously crafted to guarantee reliability, offering stable and swift energy release, which is crucial during switching operations.
Closing Operation
Upon receiving a closing command, the energy stored within the closing springs is unleashed, propelling the contacts
together with lightning-fast precision. This state-of-the-art mechanism ensures a rapid and dependable closing action, perfectly suited for a broad spectrum of
applications that demand exceptional operational performance and unwavering reliability.
Opening Operation
In opening operations, the breaker harnesses the stored energy in the opening springs, which is released instantly upon
receiving an opening command. This swift release of energy effectively forces the contacts apart, interrupting the
current flow and extinguishing the arc within the vacuum interrupter. This crucial action guarantees safe, efficient, and effective
circuit breaking, safeguarding your electrical systems with unmatched reliability.
Maintenance
Our VS1 vacuum circuit breaker is expertly engineered for simplicity in maintenance, offering remarkable durability and robust
performance even in the most challenging 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 and performance.
