MR383E Capacitor bank Didactic Equipment Electrical Engineering Training Equipment
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. It can be installed on the poles of 10/0.4kV or 6/0.4kV outdoor pole-mounted transformers. 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; adopting advanced technology at home and abroad, adopting newly designed software, 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
"Increase the capacity" of distribution transformers and 10(6)kV lines by 15%~30%
Reduce line loss by 25%~50% for 10(6)kV lines
Stabilize voltage and improve the quality of distribution voltage
