Working And Operating Principles
Arc Extinguishing Principle
Harnessing the unparalleled power of vacuum as the insulating medium, the VS1 vacuum circuit breaker elegantly executes arc extinguishing with utmost finesse. As
the contacts part, the arc is masterfully compelled to spread and extinguish swiftly, aided by the expertly generated magnetic field within the
vacuum interrupter. This highly effective process cools and condenses the arc plasma, ensuring a rapid, reliable, and thoroughly efficient arc extinguishing process,
resulting in minimal contact wear, thereby assuring stable, robust, and reliable operation.
Energy Storage
The cutting-edge energy storage system of the VS1 vacuum circuit breaker employs a sophisticated motor-driven mechanism to efficiently wind
Our advanced energy storage springs, once fully charged, ensure the breaker is primed and ready for flawless operation. This pioneering technology
has been meticulously engineered to guarantee unparalleled reliability, providing stable, swift energy release that is absolutely crucial during switching operations.
Closing Operation
Upon receiving a closing command, the energy stored within the closing springs is unleashed, propelling the contacts
together at lightning-fast speed. This state-of-the-art mechanism guarantees a rapid and dependable closing action, perfectly tailored to a wide range of
applications requiring superior operational performance and unyielding reliability.
Opening Operation
During opening operations, the breaker masterfully harnesses the energy stored in the opening springs, which is instantly released upon
receiving an opening command. This swift release of energy forcefully separates the contacts, effectively interrupting the
current flow and extinguishing the arc within the vacuum interrupter. This essential action ensures safe, efficient, and effective
circuit breaking, thus safeguarding your critical electrical systems.
Maintenance
Our VS1 vacuum circuit breaker is expertly engineered for simplicity in maintenance, offering exceptional durability and robust
performance, even in the most demanding operational environments. With regular inspections and minimal maintenance,
you can effortlessly maintain peak functionality, minimize downtime, and ensure the continuous reliability of your electrical
protection systems, all while optimizing operational efficiency to the fullest.
