Range of application:
industry with high-voltage motor or 3-10KV power supply system
or when you need to solute following problem:
1)grid voltage changed variable, sometimes high and sometimes volte, had influence the device working
2)power factor low, wastage high, or punished by electricity board
3)line loss to big, need to reduce cost
4)old capacitor need renovate
5)transformer transmission system had too much sensible load,need compensation
6)load increase, but original capacitor capacity is limited or elctric grid can not match to demand
lower remaining voltage below 50v within 5 min after device power off
main functions include compensating for wattles power, enhancing power factor, regulating power network voltage, reducing power consumption by cable,improving the quality of power supply and enhancing the efficiency of power distribution device.
1. The reactive power compensator is equipped with good discharge measures and residual voltage decreases to less than 50V when the devices cut off from network.
2. High pressure ejecting fuse are adopted as short circuit protection for single capacitor to ensure the safe operation of the devices. The main protections include neutral unbalanced current protection, split triangular voltage protection and voltage differential protection.
3. Series reactors with impedance ratio of 1%-13% is adopted to limit the switching-on current and the 3rd harmonic and above
4. Perfect protective measures including, over-current, transient break, over-voltage, low voltage and so on, with a separate protective screen to ensure safe running
