ZRTBBZ outdoor frame type reactive power automatic compensation complete set

1. An overview of the

ZRTBBZ outdoor frame type automatic reactive power compensation complete set device is suitable for reactive power compensation installed in 10kV or 6kV side of substation or industrial and mining enterprises, which can effectively improve the power factor, reduce energy loss, improve power supply quality and increase the output of the main transformer.

The product is installed outdoors, consisting of isolating switch, dedicated vacuum contactor for switching and switching shunt capacitor bank, lightning arrester, high voltage shunt capacitor, series reactor, discharge coil, spray type fuse, reactive compensation automatic control protection device, installation frame, fittings, bus bar, safety fence and so on.

The device is divided into several capacitor banks, which are controlled by microcomputer controller and automatically switched on and off by vacuum contactor according to the system load, so as to realize automatic compensation of reactive power. The device is equipped with various complete protection functions such as open triangle unbalance voltage, single capacitor failure, short circuit, over current, over voltage, under voltage and loss of voltage.

The device conforms to GB 50227-2008 "Shunt capacitor Device Design Code", JB/T7111-1993 "High voltage Shunt capacitor Device", DL/T 604-1996 "High voltage Shunt capacitor Device Ordering technical conditions" and other national industry standards. All electrical components of the device are in accordance with relevant standards.
