Working And Operating Principles
Arc Extinguishing Principle
Harnessing the unparalleled capabilities of vacuum technology as the insulating medium, the VS1 vacuum circuit breaker performs arc extinguishing with extraordinary finesse. As
the contacts part, the arc is compelled to expand and extinguish rapidly, aided by the expertly generated magnetic field within the
vacuum interrupter. This sophisticated process effectively cools and condenses the arc plasma, ensuring a swift and reliable arc extinguishing process,
resulting in minimal contact wear and assuring a stable, consistent, and reliable operation.
Energy Storage
The energy storage system of the VS1 vacuum circuit breaker employs a state-of-the-art motor-driven mechanism to efficiently wind
Our cutting-edge energy storage springs guarantee that, once fully charged, the breaker is primed and ready for flawless operation. This innovative technology
has been meticulously crafted to ensure unparalleled reliability, providing stable and swift energy release crucial for seamless switching operations.
Closing Operation
Upon receiving a closing command, the energy stored within the closing springs is unleashed, swiftly propelling the contacts
together with remarkable speed. This advanced mechanism guarantees a rapid and dependable closing action, perfectly tailored for a vast array of
applications that demand superior operational performance and unwavering reliability.
Opening Operation
In opening operations, the breaker utilizes the energy stored in the opening springs, which is released instantaneously upon
receiving an opening command. This rapid release of energy forces the contacts apart, effectively interrupting the
current flow and extinguishing the arc within the vacuum interrupter. This crucial action ensures safe, efficient, and effective
circuit breaking, thereby safeguarding your valuable electrical systems.
Maintenance
Our VS1 vacuum circuit breaker is ingeniously designed for ease of maintenance, offering exceptional durability and robust
performance even in the most challenging operational environments. With routine inspections and minimal maintenance,
you can sustain peak functionality, reduce downtime, and ensure the continuous reliability of your electrical
protection systems, while simultaneously optimizing overall operational efficiency.
