Product Profile:

The feedback reactor and the input reactor and the filter capacitor are combined with the LCL filter or the filter capacitor to form a sinusoidal filter LC.LCL mainly uses the electronic equipment, AC and DC motor drive, uninterrupted high-power UPS and servo driver, in order to eliminate the harmonic current distortion caused by the pulse rectifier, and effectively suppress the high frequency and low frequency harmonic.LC is mainly used in PWM inverter drive motor to produce higher common mode voltage and EMI caused by common mode leakage current, or can effectively suppress the peak voltage generated by long cable.In the low voltage filter cabinet, the harmonic current is used to absorb the corresponding frequency in the power grid.There are a lot of high harmonic sources such as rectifier, converter, frequency converter and so on in low voltage power grid. The high harmonics produced by them will seriously endanger the safe operation of the main transformer and other electrical equipment in the system.After the filter reactor is connected with the capacitor in series, it can not only effectively absorb the harmonic of the power grid, but also improve the power factor of the system, and play a greater role in the safe operation of the system.

Performance characteristics:

1.The core is made of high quality oriented silicon steel sheet, the core is divided into uniform pieces by multiple air gaps, the air gap of the high temperature and high strength adhesive each short column and, under the iron yoke bonded tightly together.

2.The coil adopts F and H insulation system, which greatly improves the reliability of long-term operation.

3.The reactor adopts vacuum pressure impregnation process (VPI). After high temperature curing, the noise and vibration of the product are greatly reduced in operation. The product has high mechanical strength and good moisture resistance.Greatly improves the reliability of long-term operation.

4.The utility model has the advantages of low temperature rise, small loss, high comprehensive utilization rate, and convenient installation.
