Key Product Features
1.Efficient Compensation and Energy Saving
Uses self-healing metallized parallel capacitors, which are compact, lightweight, high-capacity, reliable, and feature internal protection devices. Effectively improves power factor to above 0.95 and reduces reactive losses by over 60%.
Adopts a combination of three-phase compensation and single-phase compensation for more precise reactive power compensation, adapting to different load requirements.
Fast response (≤20ms) to grid changes, automatically switching capacitors in real-time to stabilize grid voltage and reduce system and transformer losses.
2.Intelligent Control and Protection
Equipped with an intelligent reactive power compensation controller supporting various modes like cyclic switching, code switching, and fuzzy logic automatic switching for precise compensation.
Features a self-discharge function, reducing residual voltage to below 50V within 1 minute after power off, ensuring maintenance safety.
Comprehensive electrical protection, including short-circuit, overcurrent, overvoltage, undervoltage protection mechanisms, ensures long-term stable operation.
3.Structural Design and Safety
The cabinet adopts a closed structure with a protection degree of IP30, effectively preventing foreign object intrusion. Higher protection levels (e.g., IP41 for dust and moisture resistance) are available based on the operating environment.
Designed in compliance with international and national standards such as IEC 439-1, GB7251.1, and GB/T15576, guaranteeing product safety and reliability.
Rational component layout facilitates easy installation, debugging, maintenance, and inspection.
