Working And Operating Principles
Arc Extinguishing Principle
Harnessing the unparalleled strength of vacuum as the insulating medium, the VS1 vacuum circuit breaker performs arc extinguishing with unmatched precision and finesse. As
the contacts part, the arc is compelled to spread and dissipate swiftly, facilitated by the magnetic field generated within the
vacuum interrupter. This effectively cools and condenses the arc plasma, ensuring a rapid and consistently reliable arc extinguishing process,
resulting in minimal contact wear, thus assuring stable and steadfast operation.
Energy Storage
The energy storage system of the VS1 vacuum circuit breaker incorporates an advanced motor-driven mechanism to efficiently wind
Our state-of-the-art energy storage springs ensure that, once fully charged, the breaker is primed and poised for flawless operation. This innovative technology
has been meticulously engineered to guarantee reliability, delivering stable and swift energy release critical during switching operations.
Closing Operation
When a closing command is received, the stored energy within the closing springs is dynamically unleashed, propelling the contacts
together with lightning-fast precision. This cutting-edge mechanism guarantees a rapid and dependable closing action, perfectly tailored for a diverse array of
applications that demand superior operational performance and unwavering reliability.
Opening Operation
During opening operations, the breaker effectively harnesses the energy stored in the opening springs, which is released instantaneously upon
receiving an opening command. This instantaneous release of energy forces the contacts apart, adeptly interrupting the
current flow and extinguishing the arc within the vacuum interrupter. This crucial action assures safe, efficient, and effective
circuit breaking, safeguarding your vital electrical systems.
Maintenance
Our VS1 vacuum circuit breaker is meticulously engineered for ease of maintenance, offering exceptional durability and robust
performance even in the most challenging operational environments. With routine inspections and minimal maintenance,
you can maintain peak performance, minimize downtime, and ensure the uninterrupted reliability of your electrical
protection systems, all while optimizing operational efficiency and enhancing overall performance.
