Working And Operating Principles
Arc Extinguishing Principle
Using the vacuum as a superior insulating medium, the VS1 vacuum circuit breaker achieves arc extinguishing with exceptional precision and expertise. Through sophisticated techniques, it guarantees reliable performance.
As the contacts disengage, the arc is expertly managed, spreading and dissipating rapidly, supported by the magnetic field within the
vacuum interrupter. This innovative process cools and condenses the arc plasma efficiently, ensuring a swift and dependable arc extinguishing process,
thereby reducing contact wear and ensuring consistent, stable, and reliable operation over its lifespan.
Energy Storage
The energy storage system of the VS1 vacuum circuit breaker features an advanced motor-driven apparatus that expertly winds
Our cutting-edge energy storage springs ensure that once fully charged, the breaker is primed for flawless performance. This state-of-the-art technology
is meticulously crafted to affirm reliability, offering swift and steady energy release, critical for uninterrupted switching operations.
Closing Operation
Upon receiving a closing command, the stored energy within the springs is unleashed, driving the contacts
to converge with stunning speed. This sophisticated mechanism ensures a rapid and dependable closing action, perfectly suited for a wide range of
applications that demand superior operational performance and reliability.
Opening Operation
During opening operations, the breaker efficiently employs the energy stored in the opening springs, released instantly upon
receiving an opening command. This quick energy release effectively separates the contacts, interrupting the
current flow and extinguishing the arc within the vacuum interrupter. This pivotal action ensures safe, efficient, and effective
circuit breaking, delivering comprehensive protection for your electrical systems.
Maintenance
Our VS1 vacuum circuit breaker is engineered for effortless maintenance, offering extraordinary durability and robust
performance even under the most demanding conditions. With regular inspections and minimal upkeep,
you can maintain peak functionality, minimize downtime, and ensure the reliability of your electrical
protection systems, while optimizing efficiency and enhancing operational performance.
