Working And Operating Principles
Arc Extinguishing Principle
Harnessing the immense power of vacuum as its insulating medium, the VS1 vacuum circuit breaker masterfully executes arc extinguishing with unparalleled finesse and precision. As
the contacts part, the arc is expertly directed to spread and extinguish in a swift manner, aided by the powerful magnetic field generated within the
vacuum interrupter. This sophisticated mechanism effectively cools and condenses the arc plasma, ensuring a rapid and highly reliable arc extinguishing process,
resulting in minimal contact wear and guaranteeing stable and reliable operation, providing peace of mind and exceptional performance.
Energy Storage
The cutting-edge energy storage system of the VS1 vacuum circuit breaker employs a motor-driven mechanism designed to efficiently wind
Our state-of-the-art energy storage springs are engineered to ensure that, once fully charged, the breaker is optimally primed and ready for impeccable operation. This advanced technology
has been meticulously crafted to ensure reliability, providing stable and swift energy release that is absolutely crucial during essential switching operations.
Closing Operation
When a closing command is received, the potent energy stored within the closing springs is unleashed, propelling the contacts
together with lightning-fast speed. This cutting-edge mechanism guarantees a rapid and dependable closing action, perfectly catering to a wide array of
applications that demand superior operational performance and unwavering 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 release of energy effectively forces the contacts apart, expertly interrupting the
current flow and extinguishing the arc within the vacuum interrupter. This crucial action ensures safe, efficient, and effective
circuit breaking, providing unmatched protection and safeguarding your electrical systems with peace of mind.
Maintenance
Our VS1 vacuum circuit breaker is ingeniously engineered for simplicity in maintenance, offering exceptional durability and robust
performance even in the most challenging operational environments. Through regular inspections and minimal maintenance,
you can consistently maintain peak functionality, minimize downtime, and ensure the continuous reliability of your electrical
protection systems, all while optimizing operational efficiency and delivering unmatched performance.
