Working And Operating Principles
Arc Extinguishing Principle
Harness the remarkable power of vacuum as the insulating medium with our VS1 vacuum circuit breaker, designed to execute arc extinguishing with impeccable finesse and precision. As
the contacts part, an innovative arc spreading technique is employed, compelling the arc to dissipate swiftly. This is further enhanced by the magnetic field ingeniously generated within the
vacuum interrupter. This sophisticated process effectively cools and condenses the arc plasma, ensuring a rapid and reliable arc extinguishing process,
resulting in minimal contact wear. It assures stable and reliable operation, providing peace of mind within your electrical systems.
Energy Storage
The energy storage system of the VS1 vacuum circuit breaker is a marvel of engineering, employing a motor-driven mechanism to efficiently wind
our advanced energy storage springs. Once fully charged, the breaker is primed for flawless operation. This cutting-edge technology
has been meticulously designed to guarantee unwavering reliability, ensuring stable and swift energy release crucial for seamless switching operations.
Closing Operation
Upon receiving a closing command, the energy stored within the closing springs is unleashed with precision, propelling the contacts
together at lightning speed. This state-of-the-art mechanism guarantees a rapid and dependable closing action, perfectly tailored for a wide range of
applications demanding superior performance and reliability, meeting the highest operational standards.
Opening Operation
During opening operations, the breaker skillfully harnesses the energy stored in the opening springs, releasing it instantly upon
receiving an opening command. This rapid energy release forces the contacts apart, effectively interrupting the
current flow and extinguishing the arc within the vacuum interrupter. This crucial action ensures safe, efficient, and effective
circuit breaking, safeguarding your electrical systems with unmatched reliability.
Maintenance
Our VS1 vacuum circuit breaker is designed with simplicity in maintenance, offering remarkable durability and robust
performance, even in the most demanding environments. With regular inspections and minimal maintenance,
you can maintain peak functionality, minimize downtime, and continuously ensure the reliability of your electrical
protection systems, all while optimizing operational efficiency to its fullest potential.
