Working And Operating Principles
Arc Extinguishing Principle
Harnessing the incredible power of vacuum as the insulating medium, the VS1 vacuum circuit breaker masterfully executes the arc extinguishing process with unmatched finesse and precision. As
the contacts part, the arc is expertly compelled to spread and extinguish swiftly, aided by the advanced magnetic field generated within the
vacuum interrupter. This method effectively cools and condenses the arc plasma, ensuring a rapid, reliable, and efficient arc extinguishing process,
resulting in minimal contact wear and providing assured stable and reliable operation over an extended period.
Energy Storage
The state-of-the-art energy storage system of the VS1 vacuum circuit breaker employs a robust motor-driven mechanism to efficiently wind
Our advanced energy storage springs are designed to ensure that, once fully charged, the breaker is primed and ready for impeccable operation. This cutting-edge technology
has been meticulously engineered to guarantee reliability, providing stable and swift energy release that is absolutely crucial during critical switching operations.
Closing Operation
When a closing command is received, the energy stored within the closing springs is expertly unleashed, propelling the contacts
together with lightning-fast speed. This state-of-the-art mechanism guarantees an exceptionally rapid and dependable closing action, exquisitely suited for a wide range of
applications requiring superior operational performance and unwavering reliability.
Opening Operation
In opening operations, the breaker adeptly harnesses the energy stored in the opening springs, which is released instantaneously upon
receiving an opening command. This swift release of energy effectively forces the contacts apart, thereby interrupting the
current flow and extinguishing the arc within the vacuum interrupter. This vital action ensures safe, efficient, and highly effective
circuit breaking, meticulously safeguarding your electrical systems with unmatched reliability.
Maintenance
Our VS1 vacuum circuit breaker is expertly engineered for simplicity in maintenance while offering exceptional durability and robust
performance, even in the most demanding operational environments. With regular inspections and minimal maintenance effort,
you can confidently maintain peak functionality, minimize costly downtime, and ensure the continuous reliability of your electrical
protection systems, all while optimizing operational efficiency to the highest standards.
