KS-APF active filter module is an electrical equipment based on power electronics technology, which can operate in parallel with harmonic source equipment in the power grid. It can monitor the harmonic current in the power grid and filter according to the filtering target set by the user. It filters the harmonic current by injecting a current with the same magnitude and opposite phase to the harmonic current of each frequency into the power grid.

High voltage reactive power compensation controller
KGK type high-voltage reactive power compensation controller is designed with high-performance industrial MCU as the core and in line with the domestic JB/T9663-2013 standard. It uses 128x64 dot matrix LCD Chinese English display and high-speed AD conversion technology. All data of the power grid can be obtained in one cycle, and real-time display of voltage, current, active power, reactive power, power factor, voltage harmonics, current harmonics and other grid data can be achieved. The controller has built-in Fourier transform algorithm, which can also accurately calculate the power grid data in the case of harmonics. The controller adopts the third generation switching algorithm created by our company, which has the characteristics of reasonable control and accurate compensation.

KBAM explosion-proof high-voltage shunt capacitors are mainly used in 50HZ or 60HZ AC power systems to improve power factor. The product performance complies with the domestic standard GB3983.2 High Voltage Shunt Capacitors and the international standard IE60671-1. The maximum unit capacity of AC capacitor can reach 600kvar (50Hz), which is characterized by extremely small loss and high reliability. The capacitor unit is composed of polypropylene film with insulating dielectric layer and aluminum foil electrode rolled. Different fuse technologies can be used, including internal fuse (CHDB) structure, external fuse (CHDE) structure or non fuse (CHDF) structure.
