Working And Operating Principles
Arc Extinguishing Principle
Harnessing the pristine power of vacuum as the quintessential insulating medium, the VS1 vacuum circuit breaker masterfully executes arc extinguishing with unmatched finesse. As
the contacts part, the arc is gracefully compelled to spread and extinguish with exceptional speed, expertly aided by the magnetic field generated within the
vacuum interrupter. This innovative process effectively cools and condenses the arc plasma, ensuring a rapid and reliable arc extinguishing process,
resulting in exceptionally minimal contact wear and assuring the most stable and reliable operation.
Energy Storage
The advanced energy storage system of the VS1 vacuum circuit breaker employs a sophisticated motor-driven mechanism to efficiently wind
Our cutting-edge energy storage springs ensure that, once fully charged, the breaker is primed and ready for flawless operation. This pioneering technology
has been meticulously designed to guarantee unwavering reliability, providing stable and supremely swift energy release that is crucial during rapid switching operations.
Closing Operation
Upon receiving a closing command, the energy stored within the closing springs is unleashed with precision, propelling the contacts
together with lightning-fast speed. This state-of-the-art mechanism ensures a rapid and dependable closing action, perfectly suited for an extensive range of
applications that demand superior operational performance and reliability.
Opening Operation
In opening operations, the breaker expertly harnesses the 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, 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 electrical systems with unparalleled reliability.
Maintenance
Our VS1 vacuum circuit breaker is meticulously 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 maintain peak functionality, minimize downtime, and ensure the continuous reliability of your electrical
protection systems, all while seamlessly optimizing operational efficiency.
