Working And Operating Principles
Arc Extinguishing Principle
Unleash the unrivaled power of vacuum technology with the VS1 vacuum circuit breaker, where the vacuum serves as the insulating medium. This innovative circuit breaker showcases exceptional arc extinguishing prowess with unmatched precision.
Upon separation of the contacts, the arc is strategically driven to disperse and extinguish at remarkable speed, facilitated by the magnetic field within the
vacuum interrupter. This highly efficient system rapidly cools and condenses the arc plasma, ensuring a swift and trustworthy arc extinguishing process,
thereby minimizing contact wear and ensuring consistent, stable, and reliable operation under all conditions.
Energy Storage
The sophisticated energy storage system of the VS1 vacuum circuit breaker boasts a highly efficient motor-driven mechanism that expertly winds
Our cutting-edge energy storage springs guarantee that, once fully charged, the breaker stands ready for impeccable operation. This advanced technology
has been precisely engineered to ensure utmost reliability, delivering a steady and rapid energy release vital for seamless switching operations.
Closing Operation
Upon receiving a closing command, the stored energy in the closing springs is released with precision, driving the contacts
together at incredible speed. This leading-edge mechanism ensures a quick and reliable closing action, making it ideal for diverse
applications demanding superior performance and reliability in operational execution.
Opening Operation
During opening operations, the breaker efficiently utilizes the stored energy in the opening springs, released instantaneously upon
receiving an opening command. This rapid energy release drives the contacts apart, successfully interrupting the
current flow while extinguishing the arc within the vacuum interrupter. This critical function ensures safe, efficient, and effective
circuit breaking, thereby safeguarding your electrical systems with precision.
Maintenance
Engineered for maintenance simplicity, our VS1 vacuum circuit breaker promises exceptional durability and robust
performance even in the most challenging operational environments. With scheduled inspections and minimal maintenance,
maintain peak performance, reduce downtime, and ensure the persistent reliability of your electrical
protection systems, optimizing operational efficiency to the max.
