Working And Operating Principles
Arc Extinguishing Principle
Harnessing the unparalleled power of vacuum as the insulating medium, the VS1 vacuum circuit breaker executes arc extinguishing with unparalleled finesse. As the contacts part with each operation, the arc is compelled to spread and swiftly extinguish, aided by the magnetic field meticulously generated within the
advanced vacuum interrupter. This state-of-the-art mechanism effectively cools and condenses the arc plasma, ensuring a rapid and reliable arc extinguishing process, thereby minimizing contact wear and assuring stable and dependable operation with every cycle.
The innovative design cools and condenses the arc plasma, ensuring a rapid extinguishing process that guarantees minimal contact wear, facilitating stable and reliable operation across a myriad of applications.
The result? Minimal contact wear with the assurance of stable and reliable operation, preserving the integrity and longevity of your electrical systems.
Energy Storage
The energy storage system integrated within the VS1 vacuum circuit breaker utilizes a motor-driven mechanism to efficiently wind and store energy. Our advanced technology
features cutting-edge energy storage springs ensuring that, once fully charged, the breaker stands primed and ready for faultless operation. This sophisticated technology
is meticulously crafted to guarantee absolute reliability, providing stable, swift, and effective energy release, crucial during the high-stakes moments of switching operations.
Closing Operation
Upon receiving a closing command, the stored energy within the closing springs is released with precision, propelling the contacts together at lightning-fast speed. This
state-of-the-art mechanism ensures a rapid and dependable closing action, perfectly suited for a wide range of applications demanding superior performance and
reliability. Designed for excellence, it is engineered to meet and exceed the operational requirements of the most demanding environments.
Opening Operation
During opening operations, the breaker expertly utilizes the energy stored in the opening springs, releasing it instantly upon receiving the opening command. This swift
energy release forces the contacts apart with precision, effectively interrupting the current flow and extinguishing the arc within the vacuum interrupter to
ensure safety, efficiency, and efficacy. This critical action safeguards your electrical systems, providing peace of mind with every operation.
circuit breaking, offering an unmatched level of protection to your electrical systems, ensuring they remain secure and operational at all times.
