Working And Operating Principles
Arc Extinguishing Principle
Harnessing the unparalleled power of vacuum as the insulating medium, the VS1 vacuum circuit breaker executes arc extinguishing with unmatched precision and finesse. As
the contacts part, the arc is compelled to spread and extinguish with remarkable swiftness, aided by the strategically generated magnetic field within the
vacuum interrupter. This ingenious method effectively cools and condenses the arc plasma, ensuring a rapid, reliable, and highly efficient arc extinguishing process,
resulting in minimal contact wear and assuring consistent, stable, and reliable operation.
Energy Storage
The 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 primed and ready for impeccable operation. This state-of-the-art technology
has been meticulously engineered to guarantee unmatched reliability, providing a stable and swift energy release, crucial during all switching operations.
Closing Operation
When a closing command is received, the energy stored within the closing springs is unleashed, propelling the contacts
together with lightning-fast speed. This innovative and sophisticated mechanism guarantees a rapid and dependable closing action, perfectly suited for a diverse range of
applications that demand superior operational performance and unwavering reliability.
Opening Operation
In opening operations, the breaker strategically harnesses the energy stored in the opening springs, which is released instantaneously upon
receiving an opening command. This swift and decisive release of energy forces the contacts apart, effectively interrupting the
current flow and extinguishing the arc within the vacuum interrupter. This critical action ensures safe, efficient, and superior
circuit breaking, thereby safeguarding your electrical systems with excellence.
Maintenance
Our VS1 vacuum circuit breaker is ingeniously engineered for ease of maintenance, offering exceptional durability and robust
performance even in the most demanding operational environments. With routine inspections and minimal maintenance,
you can maintain peak functionality, minimize downtime, and ensure the continuous reliability of your electrical
protection systems, all while optimizing operational efficiency to the highest standard.
