Application field

TBB High voltage automatic reactive power compensation device (hereinafter referred to as device) is mainly used for the automatic reactive power compensation device of 10kV bus-bar in 35kV or 110kV substation. According to the changes of the reactive power of the bus-bar in the substation, it can automatically control the switching of the capacitor bank to improve the power factor in the substation. The installation of the device is divided into indoor installation and outdoor installation.

Model and description

Configuration & working principle

The device is mainly composed of isolation switch,vacuum contactor,protective current transformer,spraying type fuse,high-voltage parallel capacitor,dry-type iron core reactor,discharge coil,arrester,shell,control system etc.

Working principle:The control system collects the real-time voltage and current of the bus-bar according to the voltage transformer and current transformer of the bus-bar in power substation.After calculation and processing,the controller sends the input or removal instruction to control the opening and closing action of the vacuum contactor,so as to realize the switching of the capacitor.
