Working And Operating Principles
Arc Extinguishing Principle
By leveraging the exceptional properties of vacuum as an insulating medium, the VS1 vacuum circuit breaker masterfully performs arc extinguishing with unparalleled precision and skill. Through the use of advanced techniques, it ensures dependable operation.
As the contacts disengage, the arc is expertly guided to dissipate and extinguish with remarkable speed, assisted by the magnetic field generated within the
vacuum interrupter. This method efficiently cools and condenses the arc plasma, ensuring a swift and reliable arc extinguishing process,
resulting in minimal wear on contacts and ensuring consistent, stable, and dependable operation every time.
Energy Storage
The energy storage system of the VS1 vacuum circuit breaker incorporates an advanced motor-driven mechanism to wind
Our cutting-edge energy storage springs ensure that, once fully charged, the breaker is poised for flawless performance. This state-of-the-art technology
is meticulously engineered for reliability, offering unwavering stability and rapid energy release, essential for seamless switching operations.
Closing Operation
Upon receiving a closing command, the energy stored in the closing springs is released, propelling the contacts
together with remarkable speed. This sophisticated mechanism guarantees a swift and dependable closing action, adept for a wide array of
applications where exceptional operational performance and reliability are critical.
Opening Operation
During opening operations, the breaker utilizes the energy stored in the opening springs, which is released instantaneously upon
receiving an opening command. This rapid energy release forces the contacts to separate, effectively interrupting the
current flow and extinguishing the arc within the vacuum interrupter. This pivotal action ensures safe, efficient, and effective
circuit breaking, delivering comprehensive protection for your electrical systems.
Maintenance
Our VS1 vacuum circuit breaker is engineered for effortless maintenance, providing exceptional durability and robust
performance, even in the harshest operational environments. With routine inspections and minimal maintenance,
you can maintain peak functionality, reduce downtime, and ensure continuous reliability of your electrical
protection systems, while optimizing both efficiency and operational performance.
