Working And Operating Principles
Arc Extinguishing Principle
Harnessing the unparalleled power of vacuum technology as the insulating medium, the VS1 vacuum circuit breaker performs arc extinguishing with unmatched precision and finesse. As
the contacts part, the arc is masterfully compelled to spread and extinguish with lightning speed, bolstered by the magnetic field generated within the
vacuum interrupter. This state-of-the-art process effectively cools and condenses the arc plasma, ensuring a rapid, reliable, and efficient arc extinguishing process,
resulting in minimal contact wear, thereby assuring stable and reliable operation with maximum performance longevity.
Energy Storage
The energy storage system of the VS1 vacuum circuit breaker employs a sophisticated motor-driven mechanism to efficiently wind
Our cutting-edge energy storage springs ensure that, once fully charged, the breaker is primed and ready for flawless operation. This advanced technology
has been meticulously engineered to guarantee utmost reliability, providing stable and swift energy release that is absolutely crucial during switching operations.
Closing Operation
When a closing command is received, the energy stored within the closing springs is unleashed with great force, propelling the contacts
together with lightning-fast speed. This cutting-edge mechanism guarantees a rapid, dependable, and robust closing action, perfectly suited for a diverse range of
applications that demand superior operational performance and steadfast reliability, ensuring excellence in every cycle.
Opening Operation
In opening operations, the breaker expertly harnesses the energy stored in the opening springs, which is released instantly upon
receiving an opening command. This swift and powerful 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 with unmatched precision.
Maintenance
Our VS1 vacuum circuit breaker is ingeniously engineered for simplicity in maintenance, offering exceptional durability and robust
performance even in the most demanding operational environments. With regular inspections and minimal maintenance requirements,
you can maintain peak functionality, minimize costly downtime, and ensure the continuous reliability of your electrical
protection systems, all while optimizing operational efficiency for long-lasting benefits.
