The recloser controller serves as the "protective brain" of 10-35kV medium-voltage distribution networks. Its reliability directly determines whether a line trips unnecessarily, fails to trip when needed, or causes large-scale blackouts. Currently, many devices suffer from poor material quality and

Product OverviewThe RWTSF Series Low-Voltage Dynamic Filtering and Compensation Device is designed to address complex power quality challenges commonly found in modern industrial electrical networks. By integrating advanced power electronics technology with intelligent control algorithms, the system

Product OverviewThe RWMSVC Series High-Voltage Dynamic Filtering and Compensation Device is designed to optimize power quality by regulating voltage, reactive power, and harmonic levels across high-voltage distribution networks. Traditional capacitor banks and fixed compensation devices rely on disc

Product OverviewThe RMRFC-ZJ series passive harmonic filter and reactive compensation device is specially developed for heavy-load rolling applications. In cold rolling, hot rolling, aluminum oxidation, electrophoresis, and related production lines, severe harmonic currents are generated. These harm

Product OverviewThe RMRFC-BP series passive harmonic filter is specially designed for frequency converters (VFDs). Developed and manufactured by Hongyan Electric, it applies wide-band Fourier analysis filtering technology and integrates digital monitoring modules to record and analyze key electrical

Product OverviewThe RWLX Zero-Sequence Current Absorber is designed to eliminate zero-sequence harmonic currents—primarily the 3rd, 6th, 9th, and 12th harmonics—that accumulate on the neutral line. Excessive neutral current can cause significant issues such as circuit breaker tripping, abnormal cond

In industries such assteel, petrochemicals, metallurgy, coal, and textile dyeing, nonlinear loads generate large amounts of harmonics and lead to a low power factor. These issues cause severe pollution in the power system, reduce supply quality, and compromise operational reliability.The RMRFC Serie

Product IntroductionThe RWFCKRL series is designed specifically for submerged arc furnaces (SAF), also known as mineral heat furnaces or electric arc resistance furnaces. In these systems, the electrodes are buried deep within the charge layer, forming an arc and generating heat through material res

The hybrid reactive power compensation scheme (SVG+intelligent capacitor) is an economical and efficient combination of "dynamic+steady-state" compensation. The core is to use intelligent capacitors to undertake most of the basic reactive power compensation, while allowing SVG to focus on handling t
