Low Voltage Power Capacitor

Low-voltage dry-type shunt capacitors are energy‑saving devices used for power factor correction in low‑voltage power systems operating at 50 Hz or 60 Hz. They reduce reactive power losses and improve voltage quality. The KD‑H dry‑type eco‑friendly capacitor is manufactured using advanced German technology in a Class 100 cleanroom environment. Under vacuum conditions of 10–3 bar, the components are heated while protective gas is injected. This process effectively removes air and moisture from within the capacitor, preventing electrode oxidation and localized discharge. Following this sophisticated manufacturing sequence and rigorous factory acceptance testing and quality assessments, the capacitors achieve exceptional stability and an extended service life. Depending on the application, they are available in single‑phase and three‑phase configurations.

Original Imported Low Voltage Capacitor

The original imported MOKN series capacitors are highly popular in the Chinese market thanks to their proprietary technology. During production, these capacitors are filled with nitrogen (N2), and they incorporate a unique SINECUT grooving process along with a distinctive metal‑treatment technique. Moreover, their optimally positioned internal core ensures that the device’s capacitance remains stable even under the severe stress of high‑voltage AC surges and negative pressure conditions. This hallmark feature makes the MOKN series particularly well suited for applications involving controlled equivalent DC currents and surge protection.

Low Voltage Intelligent Capacitor

The KD‑Z series intelligent low‑voltage power capacitors are a next‑generation reactive power compensation device designed for 0.4 kV low‑voltage distribution networks, delivering high efficiency and energy savings, reducing line losses, and improving the power factor and power quality. They consist of an intelligent measurement and control unit, a synchronous switching circuit, a line protection unit, and low‑voltage power capacitors. These units replace conventional automatic reactive power compensation systems that rely on discrete components—such as smart controllers, fuses, composite switches or mechanical contactors, thermal relays, low‑voltage power capacitors, and indicator lights—wired together inside and on the surface of switchgear cabinets. By eliminating the bulky, unwieldy design of traditional systems, this new generation of low‑voltage reactive power compensation equipment offers superior compensation performance, a more compact footprint, lower power consumption, reduced costs, greater cost savings, enhanced flexibility in application, simplified maintenance, extended service life, and higher reliability, thereby meeting the increasingly stringent requirements of modern power grids for reactive power management.

Low-Voltage Anti-harmonicIntelligent Power Capacitor

The KD‑ZLK harmonic‑suppression intelligent power capacitor is equipped with a custom segmented LCD display that provides real-time readings of three-phase bus voltage, three-phase bus current, three-phase power factor, frequency, the number of capacitor banks and their switching status, active power, reactive power, total harmonic distortion of voltage, and capacitor temperature.

Low VoltageTuned Reactor

The KD-LK low-voltage tuned reactor is connected in series with the compensation capacitor circuit to suppress and absorb harmonics, protect the capacitors, and mitigate the effects of harmonic voltages and currents as well as surge voltages and currents. It thereby improves power quality, increases the system’s power factor, and extends the service life of the capacitors.

Low VoltageThyristor Switching Switch

KS/TSC thyristor switches operate by detecting zero-crossings of voltage and current to ensure that capacitor banks are switched in near the voltage zero‑crossing, thereby eliminating inrush currents. Switching out is performed at current zero‑crossing, preventing transient overvoltages. These features fully meet the requirements for zero‑crossing switching of capacitors. Moreover, since the thyristor’s firing pulses are unlimited, quasi‑dynamic compensation—with response times on the order of milliseconds—is achievable, making these switches well suited for frequent capacitor switching and ideal for applications with rapidly varying loads. Compared with AC contactors, they represent a significant technological advance. The advantages of thyristor switches include zero‑crossing switching, rapid operation, and swift response, making them particularly appropriate for dynamic compensation applications.

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.

High Voltage Reactive Power Compensation Controller

The KGK-type high-voltage reactive power compensation controller is a new-generation device that integrates data acquisition, reactive power compensation, and grid parameter analysis. It is suitable for monitoring and reactive power compensation control in AC distribution systems operating at 3 kV to 35 kV and 50 Hz. Centered around a high-performance industrial MCU, the KGK-type high-voltage reactive power compensation controller is designed in compliance with the domestic JB/T 9663-2013 standard. It features a 128×64 dot-matrix LCD display supporting both Chinese and English, and employs high-speed AD conversion technology, enabling it to acquire all grid parameters within a single cycle. The controller provides real-time display of voltage, current, active power, reactive power, power factor, voltage harmonics, current harmonics, and other grid-related data. Equipped with a built-in Fourier transform algorithm, it can accurately calculate grid parameters even in the presence of harmonic distortion. Furthermore, the controller utilizes our company’s proprietary second-generation switching algorithm, offering rational control logic and precise compensation performance.
