Working And Operating Principles
Arc Extinguishing Principle
Harnessing the unparalleled power of vacuum as the insulating medium, the VS1 vacuum circuit breaker executes arc extinguishing with unparalleled finesse and precision. As
the contacts part, the magnetic field generated within the vacuum interrupter compels the arc to spread and extinguish swiftly. This dynamic action is crucial for enhancing
the cooling and condensation of the arc plasma, ensuring that the arc extinguishing process is rapid, reliable, and efficient,
resulting in minimal contact wear and providing assurance of stable, reliable operation over extended periods.
Energy Storage
The energy storage system of the VS1 vacuum circuit breaker is equipped with a sophisticated motor-driven mechanism, efficiently winding
Our state-of-the-art energy storage springs ensure that, once fully charged, the breaker is primed, poised, and ready for flawless operation. This cutting-edge technology
is meticulously engineered to guarantee reliability, offering stable and swift energy release that is critical during high-stakes switching operations.
Closing Operation
When a closing command is received, the energy stored within the closing springs is released with precision, propelling the contacts
together at lightning-fast speed. This advanced mechanism ensures a rapid and dependable closing action, making it perfectly suited for a wide array of
applications that demand superior operational performance and unyielding reliability.
Opening Operation
In opening operations, the breaker harnesses the stored energy in the opening springs, which is released instantaneously upon
receiving an opening command. This swift and powerful release of energy forces the contacts apart, effectively interrupting the
current flow and extinguishing the arc within the vacuum interrupter. This essential action ensures safe, efficient, and effective
circuit breaking, providing crucial protection and safeguarding your electrical systems.
Maintenance
Our VS1 vacuum circuit breaker is engineered for ease of maintenance, offering remarkable durability and robust
performance even in the most challenging operational environments. With scheduled inspections and minimal maintenance,
you can sustain peak functionality, reduce downtime, and ensure the unwavering reliability of your electrical
protection systems, all while optimizing operational efficiency and performance.
