Single Phase Iron Core DC Smoothing Reactor Inductor

Welcome to Huashenglong smoothing inductor webpage! In normal circumstances, the smoothing inductor is utilized to reduce harmonic current or voltage in a DC system. It can also effectively control the rise speed and peak value of short circuit in case of faults. The smoothing inductor is generally adopted in HVDC transmission system, or used in series connection with large rectifier power feeding DC motor in the steel and metallurgy enterprises.

Features-Use a Inductor:

 1 To add line impendence
 2 To provide some light buffering against low magnitude line spikes

 3 To reducing harmonics 
 4 To compensating for a low inductance motor 

 5 Only as part of a filter for reflected wave reduction

Service Conditions:

1. Service Site: Indoor/Outdoor

2. Ambient Temp.:-40~+40 degree (or according to customer’s requirement)

3. Altitude: <=1000m (if it exceeding to 1000m, pls declare in order)

4. Max. Wind Speed: 35m/s

5. Relative Humidity :< =90%

6. Earthquake Resistant Capability: horizontal direction 0.3g vertical direction 0.15g (or by customer’s requirements)

Function

1. DC inductor serves to limit superimposed AC component on the DC motor to a specified value. It can also be used in the DC decoupling side of shunt governor, for lowering intermittent current limit. The low voltage reactor has the functions of restraining and controlling circular current, and cutting fault current by DC fast switch.

2. DC inductor greatly reduces catastrophic drive failures due to transient over-voltage, it can limit the alternating component overlaying in the DC current to a certain rated value, to maintain continuous rectified current.

3. Decrease pulse value of the current, make DC-AC part more smoothly and can better power factor of the inverters to 0.95.

4. To decrease the THD to 5% or 10%, should use together with a passive filter.

HSLEC was established in 1992, and emerged as an independent manufacturer of high quality power and distribution transformers and reactors/inductors/chokes. We have the unique ability not only to produce standard units but also to design and build transformers to customers' precise requirements, including replacement units.

HSLEC produces transformers from 5kVA through 7,500kVA in voltage classes through 34.5kV. To assure compliance with applicable standards as well as with any special requirements of our customers, we test all transformers several times during the manufacturing process. Our quality control program covers all aspects of quality assurance. 

Our people, from management and engineering through manufacturing personnel, have a long tradition of experience in designing and manufacturing quality products. Together, our engineers and manufacturers craft the most reliable products in the industry.

Our long-term partners: ABB, Siemens, GE, Schneider, Fuji, Parker, etc
