Working And Operating Principles
Arc Extinguishing Principle
Harnessing the exceptional insulating power of vacuum, the VS1 vacuum circuit breaker performs arc extinguishing with unparalleled precision. As
Within the contacts part, the arc is compelled to spread and extinguish swiftly, aided by the powerful magnetic field generated within the system.
The vacuum interrupter proficiently cools and condenses the arc plasma, ensuring an exceptionally rapid and reliable arc extinguishing process,
resulting in minimal contact wear and assuring stable and reliable operation across various applications.
Energy Storage
The energy storage system of the VS1 vacuum circuit breaker is equipped with a motor-driven mechanism to efficiently wind and prepare for action.
Our advanced energy storage springs are expertly designed to ensure that, once fully charged, the breaker is primed and ready for flawless operation. This cutting-edge technology
has been meticulously crafted to guarantee reliability, providing stable and swift energy release, which is absolutely crucial during switching operations.
Closing Operation
Upon receiving a closing command, the energy stored within the closing springs is unleashed, propelling the contacts together with lightning-fast precision.
This state-of-the-art mechanism guarantees a rapid and dependable closing action, perfectly suited for a wide range of applications that demand superior operational performance and reliability.
applications that require superior operational performance and reliability.
Opening Operation
In opening operations, the breaker skillfully harnesses the energy stored in the opening springs, which is released instantly upon receiving an opening command.
This swift 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, safeguarding your electrical systems with unparalleled reliability.
