GGJ low-voltage reactive power intelligent compensation device uses computer-aided design (CAD), introduces microcomputer control, implements intelligent tracking and compensation for reactive power, its structure is reasonable, advanced technology, widely used in low-voltage power grid, improve power factor, reduce reactive power loss, improve power supply quality, is a new generation of power-saving products; It is specially used for reactive power compensation of 130-600KVA three-phase transformer.
1.It adopts intelligent controller control, complete functions, reliable performance, and automatic compensation mode: the power factor can be increased to more than 0.9;
2.Real-time display of grid power factor, display range: lag (0.00-0.99), ahead (0.00-0.99);
3.It has a variety of comprehensive protection functions such as overvoltage, overharmonic, overcompensation, system fault, phase loss, overload, etc.;
4.Memorize the set parameters, the system will not lose the parameters after the power failure, and after the power grid returns to normal, it will automatically enter the operation state without personnel on duty;
5.According to the load balance of the power grid, the phase compensation or mixed compensation can be adopted;
6.It has strong anti-interference ability, and can resist the amplitude of 2000V interference pulse directly input from the power grid, which is higher than the national professional standard.
