Working And Operating Principles
Arc Extinguishing Principle
Harnessing the unparalleled power of vacuum as the insulating medium, the VS1 vacuum circuit breaker expertly executes arc extinguishing with exceptional finesse. As
the contacts part, the arc is compelled to spread and swiftly extinguish, effectively aided by the powerful magnetic field generated within the
vacuum interrupter. This technology effectively cools and condenses the arc plasma, ensuring a rapid and reliable arc extinguishing process,
resulting in minimal contact wear, thereby assuring stable and reliable operation for an extended service life.
Energy Storage
The sophisticated energy storage system of the VS1 vacuum circuit breaker employs a highly efficient motor-driven mechanism to expertly wind
Our cutting-edge energy storage springs ensure that, once fully charged, the breaker is impeccably primed and ready for flawless operation. This advanced technology
has been meticulously designed to guarantee unwavering reliability, providing stable and swift energy release that is absolutely crucial during switching operations.
Closing Operation
Upon receiving a closing command, the energy stored within the closing springs is dynamically unleashed, propelling the contacts
together with unparalleled lightning-fast speed. This state-of-the-art mechanism guarantees a rapid and dependable closing action, perfectly suited for a wide range of
applications that demand superior operational performance and unwavering reliability.
Opening Operation
During 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 forceful release of energy separates the contacts, effectively interrupting the
current flow and extinguishing the arc within the vacuum interrupter. This vital action ensures safe, efficient, and effective
circuit breaking, thereby safeguarding your critical electrical systems with utmost precision.
Maintenance
Our pioneering VS1 vacuum circuit breaker is meticulously engineered for simplicity in maintenance, offering exceptional durability and robust
performance even in the most demanding operational environments. With regular inspections and minimal maintenance,
you can maintain peak functionality, minimize downtime, and ensure the continuous reliability of your vital electrical
protection systems, all while optimizing operational efficiency to the highest standards.
