Working And Operating Principles
Arc Extinguishing Principle
Utilizing the vacuum's power as a robust insulating medium, the VS1 vacuum circuit breaker performs arc extinguishing with unparalleled precision. Through its advanced techniques, it assures unwavering reliability in operation.
As the contacts separate, the arc is expertly driven to disperse and extinguish rapidly, supported by the magnetic field created within the
vacuum interrupter. This process adeptly cools and condenses the arc plasma, ensuring a swift and effective arc extinguishing process,
resulting in minimal contact wear and consistently guaranteeing stable, reliable operation.
Energy Storage
The energy storage system of the VS1 vacuum circuit breaker employs a cutting-edge motor-driven mechanism to efficiently wind
Our advanced energy storage springs ensure that once fully charged, the breaker is primed for flawless operation. This state-of-the-art technology
is meticulously designed to ensure reliability, offering a stable and rapid energy release, which is crucial for seamless switching operations.
Closing Operation
Upon receiving a closing command, the energy stored in the closing springs is unleashed, propelling the contacts
together with remarkable speed. This sophisticated mechanism guarantees a rapid and reliable closing action, ideally suited for a vast range of
applications demanding outstanding operational performance and reliability.
Opening Operation
During opening operations, the breaker employs the energy housed in the opening springs, instantly released upon
receiving an opening command. This immediate energy release drives the contacts apart, effectively disrupting the
current flow and extinguishing the arc within the vacuum interrupter. This vital action assures safe, efficient, and effective
circuit breaking, delivering comprehensive protection for your electrical systems.
Maintenance
Our VS1 vacuum circuit breaker is engineered for effortless upkeep, ensuring exceptional durability and robustness
even in the harshest operational environments. With routine checks and minimal upkeep,
you can maintain peak performance, reduce downtime, and ensure the continuous reliability of your electrical
protection systems, while optimizing efficiency and operational excellence.
