Overview

TBBZ series high-voltage reactive power automatic compensation device according to the 6KV, 10KV bus for the power grid and load conditions, through the control system capacitor bank automatic tracking power cut, reactive power automatic tracking compensation, power factor reached more than 0.9. It can greatly optimize the power quality, save loss and reduce consumption, and improve the transmission capacity of the transmission and distribution system.

Model Meaning

For example: TBBZ10-1500(600+900)-AK means that the voltage is 10kV, the device capacity is 1500kvar, and it is divided into two groups of automatic switching, one group is 600kvar, the other group is 900kvar, single star connection, and open triangle voltage protection.

normal conditions of use

& loz; Altitude: not high 1000m;

& loz; Ambient temperature:-25 ~ + 55C:
