Working And Operating Principles
Arc Extinguishing Principle
Harnessing the sheer might of vacuum technology as the insulating medium, the VS1 vacuum circuit breaker performs arc extinguishing with unparalleled elegance and precision. As the process unfolds,
the moment the contacts separate, the arc is compelled to propagate and extinguish with remarkable swiftness, powered by the magnetic field dynamically generated within the
vacuum interrupter. This proficient system effectively cools and condenses the arc plasma, ensuring a rapid and reliable arc extinguishing process that guarantees
minimal contact wear, while offering steadfast and dependable operation.
Energy Storage
The energy storage system of the VS1 vacuum circuit breaker is a marvel of engineering, employing a motor-driven mechanism to efficiently wind and store
power. Our cutting-edge energy storage springs ensure that once charged to full capacity, the breaker stands primed and ready for flawless execution. This innovative technology
is meticulously crafted to deliver unwavering reliability, providing a stable and swift energy discharge that is vital during critical switching operations.
Closing Operation
Upon receiving a closing command, the energy stored within the closing springs is released with precision, propelling the contacts
together at a lightning-fast pace. This cutting-edge mechanism ensures a rapid and trustworthy closing action, making it perfectly suited for a diverse range of
applications that demand superior operational performance and unmatched reliability.
Opening Operation
During opening operations, the breaker strategically harnesses the energy stored in the opening springs, releasing it instantly upon
receiving the command for opening. This swift energy release propels the contacts apart, effectively halting the
current flow and safely extinguishing the arc within the vacuum interrupter. This essential action ensures safe, efficient, and highly effective
circuit breaking, providing robust protection for your electrical systems.
Maintenance
Our VS1 vacuum circuit breaker is artfully engineered for simplicity and ease of maintenance, offering remarkable durability and robust
performance even under the most challenging operational conditions. With routine inspections and minimal maintenance efforts,
you can achieve peak performance, minimize downtime, and ensure the continuous reliability of your electrical
protection systems, all while maximizing operational efficiency and excellence.
