  • Indoor high voltage electric vacuum load break switch

    Indoor high voltage electric vacuum load break switch

    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.

  • Through-core current transformer indoor high current transformer for Inflatable Cabinet

    Through-core current transformer indoor high current transformer for Inflatable Cabinet

    LMZC-10 Current Transformer - Accurate and Reliable Solution for Current Monitoring and Protection in Power Systems The LMZC-10 Current Transformer is an exceptional device designed for precise and reliable current measurement in AC circuits. Its innovative design and advanced technology make it an ideal choice for accurate current monitoring and protection in various power systems. At the heart of the LMZC-10 is a primary coil and a secondary coil. The primary coil consists of a specific number of turns and is connected within the measurement circuit. When an AC current flows through the primary coil, it generates an alternating magnetic field around it. This magnetic field, in turn, induces an electromotive force within the secondary coil. The secondary coil is wound around the primary coil, with fewer turns than the primary coil, to ensure proportional voltage output. To maintain a stable voltage output within an appropriate range, the LMZC-10 is equipped with a compensating coil. The compensating coil has the same number of turns as the secondary coil but with a reversed winding direction. This ingenious design ensures that the induced potential in the compensating coil counteracts the induced potential in the secondary coil, resulting in a stable and accurate output voltage. The output voltage from the secondary coil is then connected to a load circuit, which generates a voltage signal proportional to the current in the primary coil. By measuring this output voltage, the magnitude of the current in the primary coil can be accurately determined. This makes the LMZC-10 an invaluable tool for current monitoring and protection in power systems. The LMZC-10 Current Transformer offers numerous advantages. Its precise measurements provide accurate data for load management and fault analysis, allowing operators to make informed decisions regarding the power system. As a key component in electrical protection systems, the LMZC-10 ensures the safety and reliability of the entire system by enabling quick and accurate detection of abnormal currents or faults. In conclusion, the LMZC-10 Current Transformer offers a reliable and accurate solution for current measurement in AC circuits. Its primary and secondary coils, along with the compensating coil, work in harmony to provide stable voltage output and precise current measurements. With its advanced features and exceptional performance, the LMZC-10 is widely used in power systems for current monitoring and protection applications. Trust the LMZC-10 to deliver accurate and reliable results for your current measurement needs, ensuring the efficiency and safety of your electrical systems.
