Working And Operating Principles
Arc Extinguishing Principle
Harnessing the unparalleled power of vacuum as the insulating medium, the VS1 vacuum circuit breaker effortlessly executes arc extinguishing with remarkable finesse. As the contacts part,
the arc is ingeniously compelled to spread and extinguish swiftly, aided by the advanced magnetic field generated within the
vacuum interrupter. This process 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.
resulting in minimal contact wear and assuring 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 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 designed to guarantee unmatched reliability, providing stable and swift energy release that is crucial during high-stakes switching operations.
Closing Operation
When a closing command is received, the potent energy stored within the closing springs is unleashed, propelling the contacts
together with lightning-fast speed. This state-of-the-art mechanism guarantees a rapid and dependable closing action, perfectly suited for a wide range of critical applications that demand superior operational performance and unwavering reliability.
applications that require superior operational performance and reliability.
Opening Operation
In opening operations, the breaker harnesses the formidable energy stored in the opening springs, which is released instantly upon
receiving an opening command. This swift and powerful release of energy forces the contacts apart, thereby 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 valuable electrical systems with unparalleled precision and reliability.
Maintenance
Our VS1 vacuum circuit breaker is expertly 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 effortlessly maintain peak functionality, minimize costly downtime, and ensure the continuous reliability of your critical electrical
protection systems, all while optimizing operational efficiency and enhancing overall performance.
