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.

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.
