Introducing the ZN28-12 series indoor high-voltage vacuum circuit breaker, a cutting-edge solution designed to optimize electrical performance and ensure efficient power distribution. This circuit breaker is equipped with a middle-sealed longitudinal magnetic field vacuum arc extinguisher and a new operating mechanism, guaranteeing reliable and safe operations. The operating mechanism and the vacuum arc extinguishing chamber adopt a front and rear layout, providing enhanced control and functionality. By connecting the operating mechanism to the movable conductive rod of the vacuum arc-extinguishing chamber through an insulating pull rod, it drives the movable contacts of the chamber to execute seamless opening and closing movements according to specified mechanical parameters. This precise movement enables the breaker to effectively break short-circuit currents and improves the mechanical life of the arc extinguishing chamber. To further enhance the circuit breaker's performance during operation, an auxiliary guide device is installed on the upper bracket of the fixed arc extinguishing chamber. This device ensures that the moving contacts remain well aligned during the opening and closing process, preventing any potential disruptions and enhancing the overall efficiency of the breaker. This innovation not only improves the short-circuit current breaking capability but also extends the lifespan of the arc extinguishing chamber. One of the key features of this series is the centrally enclosed longitudinal magnetic field vacuum arc extinguishing chamber. When the moving and static contacts open under load, the vacuum arc burns in the contact gap. However, the arc is swiftly extinguished when it crosses zero. The special structure of the contact generates a significant longitudinal magnetic field during arcing. This magnetic field evenly distributes the arc on the contact surface, resulting in a low arc voltage. Through this innovative design, the circuit breaker achieves a high arc voltage dielectric strength recovery speed. This unique characteristic significantly reduces the arc energy and electrical corrosion rate, ultimately improving the short-circuit current breaking capability and enhancing the overall lifespan of the circuit breaker. The ZN28-12 series indoor high-voltage vacuum circuit breaker is a reliable and efficient solution for various electrical systems. With its advanced features and superior performance, it plays a vital role in maintaining the stability and safety of power distribution networks. Trust in the ZN28-12 series to deliver exceptional results for your electrical needs.
