VS1 (ZN63) high voltage indoor vacuum circuit breaker is a cutting-edge electrical device designed to ensure safe and efficient power distribution in high voltage systems. Equipped with a permanent magnetic operating mechanism, this circuit breaker utilizes a vacuum arc extinguishing chamber, where vacuum serves as both the arc extinguishing and insulation medium. When the live operation of the VS1-12 vacuum circuit breaker is initiated, the dynamic and static contacts within the operating mechanism create a vacuum arc between them. Additionally, the unique structure of the contacts generates an appropriate longitudinal magnetic field within the contact gap. This causes the vacuum arc to assume a diffusion form and enables it to uniformly distribute across the contact surfaces, maintaining a low arc voltage. As the current naturally crosses zero, the residual ions, electrons, and metal vapors rapidly recombine or deposit on the contact surfaces and shield, restoring the dielectric strength of the arc extinguishing chamber. Consequently, the arc is extinguished, achieving the desired breaking effect. The utilization of a magnetic field to control the vacuum arc empowers the VS1 vacuum circuit breaker with a robust and stable breaking current capacity. In summary, the VS1 (ZN63) high voltage indoor vacuum circuit breaker possesses advanced features that allow for efficient and reliable power distribution in high voltage applications. By utilizing vacuum technology and a magnetic control mechanism, this circuit breaker ensures the safe interruption of electrical currents, presenting itself as an excellent choice to safeguard various electrical installations and systems.
