Working and Operating Principles
Arc Extinguishing Principle
Embrace the cutting-edge power of vacuum technology with our VS1 vacuum circuit breaker, which masterfully executes arc extinguishing with unparalleled precision.
As the contacts part, witness the arc deftly extend and extinguish with remarkable speed, a feat achieved through the innovative magnetic field generated within the
vacuum interrupter. This advanced process effectively cools and condenses the arc plasma, ensuring a swift and dependable extinguishing of the arc,
resulting in minimal contact wear while guaranteeing stable and reliable operations, providing you peace of mind.
Energy Storage
The energy storage system in the VS1 vacuum circuit breaker utilizes a motor-driven mechanism that efficiently winds
our sophisticated energy storage springs. Once fully charged, the breaker is poised for impeccable functionality. This technology
is meticulously crafted to assure unwavering reliability, furnishing stable and rapid energy release that is indispensable during crucial switching operations.
Closing Operation
Upon receiving a closing command, the energy stored in the closing springs is unleashed, propelling the contacts
together with exceptional speed. This cutting-edge mechanism ensures a rapid and reliable closing action, adeptly suited for a diverse range of
applications demanding superior operational performance and steadfast reliability.
Opening Operation
In opening operations, the breaker expertly utilizes the energy stored in the opening springs, releasing it instantly upon
receiving an opening command. This swift release of energy forces the contacts to part, effectively interrupting the
current flow and extinguishing the arc within the vacuum interrupter, ensuring safe, efficient, and effective
circuit-breaking, which robustly safeguards your electrical systems.
Maintenance
Our VS1 vacuum circuit breaker is engineered for hassle-free maintenance, boasting exceptional durability and steadfast
performance even in the most challenging operational environments. With routine inspections and minimal maintenance,
you can uphold peak functionality, reduce downtime, and ensure the continuous reliability of your electrical
protection systems, all while maximizing operational efficiency.
