Working And Operating Principles
Arc Extinguishing Principle
Harnessing the unparalleled power of vacuum as the insulating medium, the VS1 vacuum circuit breaker performs arc extinguishing with exceptional finesse and precision. As
the contacts part, the arc is compelled to spread and extinguish with incredible swiftness, aided by the magnetic field ingeniously generated within the
vacuum interrupter. This brilliant engineering effectively cools and condenses the arc plasma, ensuring a rapid and utterly reliable arc extinguishing process,
resulting in minimal contact wear, thereby assuring stable and dependable performance with exceptional reliability.
Energy Storage
The advanced energy storage system of the VS1 vacuum circuit breaker employs a cutting-edge motor-driven mechanism to efficiently wind
Our state-of-the-art energy storage springs ensure that once fully charged, the breaker is primed for flawless operation, ready to perform without a hitch. This technology
has been meticulously designed for impeccable reliability, ensuring stable and swift energy release, which is crucial during critical switching operations.
Closing Operation
Upon receiving a closing command, the stored energy within the closing springs is unleashed with precision, propelling the contacts
together at lightning-fast speed. This advanced mechanism guarantees an exceptionally rapid and dependable closing action, perfectly suited for a vast range of
applications that demand superior operational performance and unwavering reliability.
Opening Operation
During opening operations, the breaker efficiently harnesses the energy stored in the opening springs, which is released instantly upon
receiving an opening command. This swift and powerful release of energy forcefully drives the contacts apart, effectively interrupting the
current flow and extinguishing the arc within the vacuum interrupter. This crucial action ensures safe, efficient, and robust
circuit breaking, providing exceptional protection for your electrical systems.
Maintenance
Our VS1 vacuum circuit breaker is expertly engineered for simplicity in maintenance, offering unparalleled durability and robust
performance even in the most challenging operational environments. With routine inspections and minimal maintenance,
you can achieve peak functionality, minimize downtime, and ensure the continuous reliability of your vital electrical
protection systems, all while optimizing operational efficiency for lasting performance.
