Working And Operating Principles
Arc Extinguishing Principle
Harnessing the extraordinary power of vacuum as the premier insulating medium, the VS1 vacuum circuit breaker executes its arc extinguishing process with unparalleled finesse and precision. As the
contacts separate, the electric arc is compelled to spread and extinguish rapidly, aided by the strategically generated magnetic field within the
vacuum interrupter. This not only effectively cools and condenses the arc plasma but also guarantees a swift and reliable arc extinguishing process,
resulting in minimal contact wear while assuring stable and highly reliable operation, even under the most demanding conditions.
Energy Storage
The cutting-edge energy storage system of the VS1 vacuum circuit breaker employs an advanced motor-driven mechanism to efficiently wind up the energy.
Our state-of-the-art energy storage springs ensure that, once fully charged, the breaker is primed and ready for flawless and immediate operation. This forward-thinking technology
has been meticulously engineered to guarantee reliability, providing a stable and swift energy release that is crucial during critical switching operations.
Closing Operation
Upon receiving a closing command, the energy stored within the closing springs is dynamically unleashed, propelling the contacts
together at lightning-fast speeds. This state-of-the-art mechanism ensures a rapid and dependable closing action, perfectly suited for applications requiring
superior operational performance and unyielding reliability across a wide range of scenarios.
Opening Operation
During opening operations, the breaker harnesses the energy stored in the opening springs, which is released instantaneously upon
receiving an opening command. This swift discharge of energy forces the contacts apart, effectively interrupting the
current flow and efficiently extinguishing the arc within the vacuum interrupter. This crucial action ensures safe, efficient, and effective
circuit breaking, safeguarding your valuable electrical systems with the utmost reliability.
Maintenance
Our VS1 vacuum circuit breaker is meticulously engineered for effortless maintenance, ensuring exceptional durability and robust
performance, even in the most demanding operational environments. With regular inspections and minimal maintenance requirements,
you can effortlessly maintain peak functionality, minimize downtime, and ensure the unwavering reliability of your electrical
protection systems, all while optimizing operational efficiency to the fullest.
