Low-voltage reactive power intelligent compensation device




GGJ low-voltage reactive power compensation device using computer-aided design (CAD), the introduction of microcomputer control. inteligent implementation of inteligent tracking compensation,its reasonable structure, advanced technology, widely used in low-voltage power grid,improveower factor, reduce reactive power loss, improve power supply guality, is a new generation of energy-saving products.Dedicated to the 130-600K V three-phase transformer reactive power compensation.

Main feature

◇Intelligent controller control, full-featured. Reliable performance, automatic compensation: can increase the power factor to 0.9 or more; 

◇Real-time display power grid power factor, display range: lag (0.00-0.99), ahead (0.00-0.99);

◇With over-voltage, harmonic, over compensation, system failure, lack of phase, overload and other comprehensive protection;

◇Memory has been set parameters, the system will not lose the parameters after power failure, the grid back to normal, automatically enter therunning state, no personnel on duty;

◇According to the grid load balance, to take the phase compensation or mixed compensation;

◇Anti-interference ability, can withstand the direct input from the grid amplitude of 2000V interference pulse, higher than the nationalprofessionalstandards;
