Working And Operating Principles
Arc Extinguishing Principle
Utilizing vacuum as the insulating medium, the VS1 vacuum circuit breaker executes arc extinguishing with exceptional precision. As
In the intricately designed contacts part of our vacuum interrupters, the arc is expertly compelled to spread and extinguish swiftly, significantly aided by the precision-generated magnetic field within the unit.
This advanced vacuum interrupter effectively cools and condenses the arc plasma, ensuring a rapid, reliable, and efficient arc extinguishing process,
resulting in minimal contact wear while assuring stable, reliable, and long-lasting operation.
Energy Storage
The highly efficient energy storage system of the VS1 vacuum circuit breaker integrates a motor-driven mechanism designed to expertly wind
The cutting-edge energy storage springs are engineered to ensure that, once fully charged, the breaker is primed and ready for flawless operation. This state-of-the-art technology
has been meticulously designed to guarantee unwavering reliability, delivering stable and swift energy release critical for seamless switching operations.
Closing Operation
Upon receiving a closing command, the energy stored within the closing springs is dynamically unleashed, propelling the contacts
together with exceptional lightning-speed precision. This cutting-edge mechanism ensures a rapid, dependable, and precise closing action, ideal for a wide range of
applications demanding superior operational performance and unmatched reliability.
Opening Operation
During opening operations, the system harnesses the stored energy in the opening springs, instantly released upon receiving
an opening command. This swift energy discharge effectively forces the contacts apart, adeptly interrupting the
current flow, and extinguishing the arc within the vacuum interrupter. This critical function ensures safe, efficient, and highly effective
circuit breaking, providing robust safeguarding for your electrical systems.
Maintenance
Our VS1 vacuum circuit breaker is crafted for ease of maintenance, delivering exceptional durability and robust
performance even under the most demanding operational conditions. With routine inspections and minimal maintenance,
you ensure peak functionality, reduce downtime, and maintain the continuous reliability of your electrical
protection systems, all while optimizing operational efficiency to its fullest potential.
