Working And Operating Principles
Arc Extinguishing Principle
The VS1 vacuum circuit breaker leverages the intrinsic power of vacuum as an insulating medium to perform arc extinguishing with exquisite accuracy and finesse. Employing cutting-edge techniques, it assures dependable performance.
As the contacts disengage, the arc is skillfully manipulated to expand and be extinguished expeditiously, bolstered by the magnetic field generated within the
vacuum interrupter. This mechanism efficiently cools and condenses the arc plasma, assuring a swift and reliable arc extinguishing process,
culminating in minimal contact wear and ensuring consistent, stable, and trustworthy operation.
Energy Storage
The energy storage system in the VS1 vacuum circuit breaker is powered by a sophisticated motor-driven mechanism that efficiently tension the springs for energy storage,
Our advanced energy storage springs are designed to ensure that once fully charged, the breaker is primed for impeccable operation. This innovative technology
is intricately engineered to provide reliability, offering consistent and rapid energy release, vital for flawless switching operations.
Closing Operation
Upon receiving a closing directive, the energy stored in the closing springs is released, driving the contacts
together with remarkable swiftness. This sophisticated mechanism guarantees a prompt and reliable closing action, perfectly suited for a wide range
of applications that demand superior operational performance and dependability.
Opening Operation
During opening operations, the breaker capitalizes on the energy stored in the opening springs, which is instantaneously released upon
receiving an opening order. This rapid energy release propels the contacts apart, effectively interrupting the
current flow and extinguishing the arc inside the vacuum interrupter. This pivotal action ensures safe, efficient, and potent
circuit breaking, delivering comprehensive protection for your electrical systems.
Maintenance
Our VS1 vacuum circuit breaker is crafted for effortless maintenance, offering exceptional durability and robust
performance, even in the harshest operational environments. Through routine checks and minimal upkeep,
you can maintain peak functionality, minimize downtime, and ensure the continuous reliability of your electrical
protection systems, while optimizing efficiency and operational performance.
