JLKCS Series Fast Dynamic Reactive Power Compensation Controller

Product Overview

The JLKCS series fast-acting dynamic reactive power compensation controller is a power-electronic device designed for the rapid switching of power compensation capacitors. Its electrical structure primarily consists of high-power anti-parallel thyristor modules, isolation circuits, triggering circuits, synchronization circuits, control and protection circuits, and driver circuits. It is equipped with control signal terminals and offers two switching modes: three-phase common compensation and three-phase independent split-phase compensation. The device features strong anti-interference capabilities, ease of installation and maintenance, a rapid switching response time of less than 20ms, zero-inrush current switching, silent operation, and high stability and reliability. Additionally, it includes functions such as phase-loss protection and operating status indication, making it an ideal component for capacitor bank switching in dynamic reactive power compensation systems.
