Working And Operating Principles
Arc Extinguishing Principle
Harness the unparalleled power of vacuum technology as the insulating medium with the VS1 vacuum circuit breaker, meticulously designed to execute arc extinguishing with extraordinary finesse and precision. As
the contacts separate, the arc is skillfully compelled to spread and be extinguished swiftly, aided by the powerful magnetic field generated within the
vacuum interrupter. This innovative process effectively cools and condenses the arc plasma, ensuring a rapid, reliable, and efficient arc extinguishing process,
resulting in minimal contact wear, assuring stable and consistent operation with unmatched reliability.
Energy Storage
The energy storage system in the VS1 vacuum circuit breaker features a highly efficient, motor-driven mechanism that expertly winds
Our state-of-the-art energy storage springs ensure that once fully charged, the breaker is primed and ready for flawless operation. This cutting-edge technology
has been meticulously engineered to guarantee unwavering reliability, providing stable and swift energy release, which is absolutely crucial during switching operations.
Closing Operation
Upon receiving a closing command, the stored energy within the closing springs is unleashed with precision, propelling the contacts
together with unrivaled speed. This advanced and state-of-the-art mechanism ensures a rapid, dependable closing action, perfectly designed for a wide range of
applications demanding superior operational performance and unwavering reliability.
Opening Operation
In opening operations, the breaker seamlessly harnesses the energy stored in the opening springs, releasing it instantly upon
receiving an opening command. This swift release of energy effectively forces the contacts apart, skillfully interrupting the
current flow and extinguishing the arc within the vacuum interrupter, ensuring a safe, efficient, and effective
circuit-breaking process that safeguards your electrical systems with confidence.
Maintenance
Our VS1 vacuum circuit breaker is ingeniously engineered for effortless maintenance, offering exceptional durability and robust
performance, even in the most demanding operational environments. With regular inspections and minimal maintenance,
you can ensure peak functionality, minimize downtime, and maintain the continuous reliability of your electrical
protection systems, all while optimizing operational efficiency to the highest standards.
