Low Voltage Capacitor Switching Switch
The KS/FK capacitor switching switch employs a parallel configuration of thyristor switches and magnetic‑hold switches, combining the zero‑crossing switching advantages of thyristors during turn‑on and turn‑off with the zero‑power‑consumption benefits of magnetic‑hold switches during normal operation.
Low-voltage Svg StaticVar Generator Module
The KS‑SVG low-voltage static var generator is a three-phase full-bridge voltage-source converter composed of fully controlled power electronic devices—IGBTs. By adjusting the phase and magnitude of the AC-side output voltage of the bridge circuit, it can either absorb or inject reactive power to meet specified requirements, thereby achieving dynamic reactive power compensation. This low-voltage static var generator is primarily used in low-voltage systems to improve the power factor while simultaneously compensating for harmonic currents and unbalanced currents. It features fast response, high compensation accuracy, and flexible compensation modes, capable of compensating both capacitive and inductive reactive power.
Low Voltage APFActive Filter Module
The KS-APF active filter module is an electrical device based on power electronics that can operate in parallel with harmonic‑generating equipment connected to the grid. It monitors the harmonic current conditions in the grid and performs filtering according to user‑defined target parameters. By injecting into the grid a current that is equal in magnitude but opposite in phase to the harmonic currents at each frequency, it effectively eliminates harmonic distortion.
