Product Desciption

Product description:

DC smoothing reactor is used for the direct current side of a current rectifier, the DC current flows through these reactors.If the DC ripple of DC motor is too high due to the connection of rectifier, it is necessary to use these reactors to realize the commutation without fault and reduce the motor loss.In the case where the rated DC current I dn is not exceeded, the inductance L of the reactor is almost constant.

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.

Performance parameter:

1. 额定工作电压:380/660V  50/60HZ

2.Rated operating current:3A~1600A@40℃ 

3.Use altitude:≤2000m 

4.Insulation resistance:>100MΩ 

5.Reactor noise:<65Db 

6.Protection level:IP00

7.Insulation grade:F/H

8.Maximum current:1.5 times rated current. continue for 60S

9.Dielectric strength:3000VAC/50HZ/5mA/60s no arcing breakdown

10.Temperature rise:Iron core≤85K Wire pack temperature≤95K

11.Use environment:-10+45℃, ratings will not reduce the degrees.Up to +55℃.At 45℃ above,  the rated current drops by 2% when the temperature is increased by 1℃

12.Product execution standards:GB10229-88, JB9644-1999 semiconductor electric drive reactor
