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.

KYN28-24 switchgear is a high-voltage switchgear, mainly used in substations, industrial and mining enterprises, and urban distribution networks. The following is an explanation of the product working principle of the KYN28-24 switchgear: Main components: KYN28-24 switchgear is composed of main components such as circuit breaker, isolating switch, grounding switch, motor drive mechanism and interlocking device. These components work together to make the switchgear work properly. Workflow: When the power system fails or needs to be repaired, KYN28-24 switchgear plays a key role. First, isolate the faulty part from the power system by operating a circuit breaker. Then use the isolation switch to completely isolate the faulty part from the rest. Then, ground the faulty part through the grounding switch to ensure personal safety and equipment protection. Finally, the motor drive mechanism is used to control the switching state of the switchgear to realize the normal operation of the system. Protection function: KYN28-24 switchgear has a variety of protection functions, mainly including over-current protection, over-voltage protection, short-circuit protection and grounding protection. When an abnormal situation occurs in the power system, the switchgear will automatically perform protection operations to avoid further damage. Interlocking device: In order to ensure work safety, KYN28-24 switchgear is also equipped with an interlocking device. The interlocking device can prevent misoperation and mutual interference, ensure the normal operation of each component, and reduce the risk of accidents. In short, the working principle of KYN28-24 switchgear is to realize the isolation, cut-off and protection of power system failure and maintenance work through reasonable configuration and arrangement of various main components. Its efficient and reliable working performance makes it an indispensable device in the power system. Our KYN28-24 switchgear has undergone strict quality inspection and can provide stable and reliable services to meet customer needs.
