I. Overview
This low-voltage reactive power compensation box is suitable for rural and urban distribution networks and internal distribution networks of industrial and mining enterprises. Power compensation; it can also be used in low-voltage power grids in factories and mines, petroleum, chemical, railways, ports and other industries and for on-site reactive power compensation of power equipment. It adopts single-chip control technology and the sampling signal measurement system is three-phase analog or three-phase electronic Measurement and switching thresholds can be set by the user or controlled by fuzzy logic; stable and reliable work; the actuator for controlling the switching of capacitors uses capacitive non-contact dedicated for switching capacitors Switch, suitable for occasions where the load changes frequently.
Using this equipment can provide the following benefits:
Improve the power factor of the grid without returning reactive power
Stabilize voltage and improve the quality of distribution voltage
