Energy Feedback
Reactor
The feedback reactor is applied in
LCL filter at the input end of four quadrant converter, and makes
the phase series connection with the input end of frequency
inverter. When the inverter brakes, the regenerative energy is
fed back to the grid and used, while the rectifier unit is IGBT,
which will produce more high harmonic currents, which will cause
pollution to the power grid. Therefore, the feedback reactor
shall be installed to make filter improvement.
Product
performance
1.The iron core adopts the high
quality silicon steel, the core is divided into uniformed pieces
via multiple air gap , the air gap adopts the high temperature
and high strength adhesive to tightly bond each smallsection
ofcore and the upper and lower iron yoke;
2. The coil adopts H, C grade
insulation system, which greatly improves the reliability of
long-term operation;
3.Thereactor adopts vacuum
pressure impregnation process (VPI), the products after high
temperature drying curing has greatly reduced noise and vibration
in operation. The product has high overall mechanical strength
and sound moisture-proof performance, which greatly improves the
reliability of long-term operation;
4.Low temperature rise, low loss,
high comprehensive utilization rate, easy to install.
