TBB Series High Voltage Reactive Power Compensation Device

TBB Series of High-Voltage reactive power compensation device
1, Outline
 
   With the development of the national economy, various industries and civil loads are significantly increased, the new load current increases in reactive load power system losses, so to be on the grid reactive power compensation. NTBB sets of high-voltage shunt capacitor device consists of high voltage switchgear, shunt capacitor, series reactor, consisting of zinc oxide surge arresters, discharge coil, post insulators, grounding switch. Fuse in series with the capacitor device, when some internal capacitors in series segment breakdown, the fuse action, the Taiwanese capacitor rapidly excised from the capacitor bank, effectively prevent the failure to expand. Discharge coil shunt capacitor circuits, when the group launched the run from the power supply capacitor, the voltage on the capacitor to make a reputation within 5 seconds since the peak rated voltage drops below 50V. MOA and connect the line to limit the switched capacitor caused by over-voltage operation. Series reactors in series with the capacitor circuit to limit the switching capacitor banks in high harmonics, reduce inrush current.
