High Voltage Series Reactor

Category:

Explosion-proof high-voltage series reactors are primarily used in 6 kV to 35 kV power systems, connected in series with high-voltage capacitor banks. They effectively suppress and absorb higher-order harmonics, limit switching inrush currents and operational overvoltages, protect the capacitor banks, improve the system’s voltage waveform, and enhance the power factor of the grid.

Main Technical Parameters

● Suitable for system voltages of 6 kV, 10 kV, and 35 kV.
● Reactance rates: 1%, 4.5%, 5%, 6%, 7%, 12%, 14%
● Insulation class: Class F; reactor noise: ≤45 dB
● Overload capacity: continuous operation at ≤1.35 times the rated value
● The phase-to-phase imbalance of the reactor shall not exceed +3%, and the inductance tolerance shall be within +3%.
● This reactor is available in both three-phase and single-phase configurations, both of which are epoxy‑cast type.
● The core is made of high‑quality, low‑loss cold‑rolled grain‑oriented silicon steel sheets, which are punched and sheared on a high‑speed press. This process yields minimal burrs, uniform and regular cuts, and neatly stacked laminations, ensuring the reactor operates with low temperature rise and low noise.
● The coil is of the epoxy‑cast type, with epoxy‑glass mesh fabric laminated on both the inner and outer surfaces for reinforcement. It is cast under vacuum using an F‑class epoxy casting system. This coil not only exhibits excellent insulation performance but also boasts high mechanical strength, enabling it to withstand high‑current surges and thermal shock without cracking.
● Epoxy‑cast windings are non‑absorbent and exhibit low partial discharge levels, enabling safe operation under harsh environmental conditions.
● The upper and lower ends of the coil are fitted with epoxy spacers and silicone rubber vibration-damping pads, effectively reducing vibration during operation.

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.
