Introduction
High-voltage reactive power automatic compensation device is widely used in power system, industrial and mining enterprises distribution network. In order to improve power factor, reduce line loss, and improve voltage quality of system, according to the demand of reactive power, it realizes the synthetically automatic control of reactive power and voltage by setting capacitor group mode ,automatically switching compensation capacitor and regulating on-load tap changing transformer.
Feature
1. Equipped with high tech power factor controller to detect the reactive power and finally to switch on/off in minimum times. The controller can be remote controlled by connecting with computer. The parameters can be transferred to computer by communication port(485).
2. Optimizing and matching capacitor group and reactor parameters, which can effectively suppress switching inrush and high harmonic.
3. Using special vacuum switch of switching capacitor group , suitable for frequently switch, no resignation, no bouncing.
4. The explusion fuse and relay protection, protection of the overvoltage, under voltage, over current, instantaneous current, open delta voltage and fault locking, which ensure safe operation of the device.
5. Equipped with high voltage display device, magnetic lock and watch window.
6.Force locking function to keep the operator safe.
7. The device is composed of incoming line isolation cabinet and several groups auto-switching compensation cabinet;

Model Selection Guide
Please specify the rated voltage, the equipment rated capacity and its group, what is your special requirement?
HVCA automatic compensation equipment is almost cabinet type, which can be fixed in the capacitor room, power distribution room.
The solution of equipment capacity should consider reactance rate, capacitor group and system short-circuit capacitor relationship to avoid system resonance.
If the capacitor rated voltage is higher than bus bar voltage or equipped with series reactors, we should calculate output capacity and raged capacity.
The configuration and size can be customized per customer's requirement.
Example
The system rated voltage: 6Kv Demand:1800kvar compensation capacity
Require:6% reactor which can detune 5 times or above harmonic and limit inrush current.
Our solution: HVCA-6-1800/300+600+900 reactive power automatic compensation equipment. Its group is 1:2:3,which can realize 6 steps compensation. It is three cabinets combined ,total size 3600x1600x2500mm.
