Working And Operating Principles
Arc Extinguishing Principle
Harnessing the unparalleled prowess of vacuum technology as the insulating medium, the VS1 vacuum circuit breaker masterfully executes arc extinguishing with impeccable finesse. As
the contacts separate, the arc is expertly compelled to spread and extinguish with remarkable swiftness, aided by the formidable magnetic field generated within the
vacuum interrupter. This sophisticated process effectively cools and condenses the arc plasma, ensuring a rapid, reliable, and efficient arc extinguishing process,
resulting in minimal contact wear and assuring a stable, reliable operation that enhances the longevity of your system.
Energy Storage
The energy storage system of the VS1 vacuum circuit breaker employs a state-of-the-art motor-driven mechanism to efficiently wind and store energy.
Our cutting-edge 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 unparalleled reliability, providing a stable and swift energy release that is crucial for successful switching operations.
Closing Operation
Upon receiving a closing command, the energy stored within the closing springs is unleashed with precision, propelling the contacts
together at lightning-fast speed. This cutting-edge mechanism guarantees a rapid and dependable closing action, perfectly tailored for a wide range of
applications that demand superior operational performance and unwavering reliability.
Opening Operation
In opening operations, the breaker adeptly harnesses the energy stored in the opening springs, which is released instantly 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 vital action ensures safe, efficient, and effective
circuit breaking, providing robust protection for your electrical systems.
Maintenance
Our VS1 vacuum circuit breaker is meticulously engineered for simplicity in maintenance, offering exceptional durability and rugged
performance even in the most challenging operational environments. With regular inspections and minimal maintenance,
you can ensure peak functionality, minimize downtime, and sustain the continuous reliability of your electrical
protection systems, while optimizing operational efficiency and excellence.
