Working And Operating Principles
Arc Extinguishing Principle
Discover the unparalleled efficiency of the VS1 vacuum circuit breaker, which masterfully utilizes vacuum as its insulating medium to achieve exceptional arc extinguishing performance.
As the contacts disengage, the arc is expertly managed to dissipate quickly, thanks to the magnetic field ingeniously generated within the
vacuum interrupter. This process effectively cools and condenses the arc plasma, ensuring a swift and reliable extinguishing operation.
This results in greatly reduced contact wear, promising consistent and stable performance over time.
Energy Storage
The revolutionary energy storage system of the VS1 vacuum circuit breaker features a motor-driven mechanism that efficiently charges
Our cutting-edge energy storage springs, once fully charged, set the stage for impeccable operation. This sophisticated technology
is precisely engineered to ensure reliability, delivering stable and rapid energy release, which is essential for switching operations.
Closing Operation
Upon receiving a closing command, the energy stored in the closing springs is unleashed, driving the contacts
together with remarkable speed. This advanced mechanism ensures a quick and reliable closing action, ideally suited for various
applications demanding top-tier operational performance and reliability.
Opening Operation
During opening operations, the breaker efficiently utilizes the energy stored in the opening springs, which is instantaneously released upon
receiving an opening command. This rapid energy release separates the contacts, effectively interrupting the
current flow and extinguishing the arc within the vacuum interrupter. This crucial function secures safe, efficient, and effective
circuit breaking, providing steadfast protection for your electrical systems.
Maintenance
Our VS1 vacuum circuit breaker is meticulously designed for easy maintenance, offering outstanding durability and reliable
performance even in the harshest environments. With regular inspections and minimal upkeep,
you can ensure peak functionality, reduce downtime, and maintain the unwavering reliability of your electrical
protection systems, all while maximizing operational efficiency.
