Most of the load types in the power system belong to the perceptual load, and the widespread use of power electronic equipment by power enterprises makes the power factor of the network lower.Lower power factor reduces equipment utilization rate, increases power supply investment, damages voltage quality, reduces equipment service life, and greatly increases line loss.Therefore, by connecting the capacitor compensation cabinet in the power system, the perceptual load can be balanced, the power factor can be improved, and the utilization rate of the equipment can be improved.

The function of compensation cabinet is to raise the line voltage and reduce the reactive power loss by using the parallel connection of capacitor when the current leads the voltage 90 degrees.The capacitor compensation cabinet is full of compensation capacitors and contactors, that is to say, it uses the phase-shifting principle of capacitors to compensate the reactive power loss generated by the equipment.General power failure or power supply does not need to operate, it can be with the opening and closing of the main power supply in parallel operation.Generally, as long as the attention to check at any time inside the capacitor has leakage or abnormal sound and other abnormal conditions can be.

Capacitive compensation cabinet compensates inductive reactance of inductance load by capacitive reactance.Reduce reactive current to achieve energy saving effect.
