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.

The FZN25-12D type vacuum load break switch and FZRN25-12D type combination appliance adopt a overall structure where the operating mechanism is arranged on the side of the main circuit (available in right or left side arrangement according to user's needs). The main conducting part consists of insulation cover, static contact, movable contact, conductive cylinder, and vacuum arc chamber. The combination appliance also includes a current-limiting fuse. This product uses the TF351 type vacuum arc-extinguishing chamber with a ceramic outer casing and 25 copper contacts. It features a flat contact structure, which results in minimal electrical wear and a long service life. With high breaking and closing capabilities, it offers strong performance and easy operation and maintenance. The fused switch is integrated with the operating mechanism, combining the functions of an isolating switch, load switch, and grounding switch into one compact structure. It has a small size, convenient installation, and flexible operation. The switch is equipped with a dynamic isolated contact and a vacuum arc-extinguishing chamber, which are arranged in series and linked according to the specified operating procedure, achieving a one-time operation. The cone-shaped static contact, insulation cover, and movable contact structure separate the busbar and load switch units, ensuring the personal safety of workers. When the grounding switch is closed, the movable contact automatically isolates the breaking point, providing excellent protection. The switch, grounding switch, movable contact, and cabinet door light are strictly in accordance with the "five preventions" mechanical interlocking to prevent misoperation. The switch mechanism is a spring-stored energy type, featuring both manual and electric energy storage functions. Once energy storage is complete (with the spring at the midpoint), it will automatically close, and for opening, it can be done manually with a decoupling lever or by an electromagnetic coil. This facilitates the implementation of remote control requirements for switch opening and closing operations. The switch can be powered by both AC and DC sources, and its working principle is similar to that of a circuit breaker. It is generally equipped with a simple arc extinguishing device, but its structure is relatively simple. The diagram shows a type of compressed air high-voltage load break switch. During breaking, under the action of the opening spring, the main shaft rotates clockwise. On one hand, the piston moves upward by compressing the gas through the crank-slider mechanism; on the other hand, the transmission system composed of two sets of four-link mechanisms opens the main contact first, and then the arc extinguishing contacts, blowing out the arc with the compressed air from the nozzle. When closing, the main contact and arc extinguishing contacts rotate clockwise at the same time under the action of the main shaft and the transmission system, with the arc contacts closing first and then the main contacts closing subsequently. During closing, the opening spring is also storing energy. As the load break switch cannot interrupt short-circuit currents, it is often used in combination with a current-limiting high-voltage fuse to not only complete the function of breaking the circuit but also reduce the thermal and mechanical forces caused by short-circuit currents.

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.
