Smoothing Reactor
Rated Voltage: Up to 1100 kV
Functional Overview
Connected in series with HVDC transmission lines, it serves in converter stations or back-to-back interconnects between power grids. Core functions include:
1.Suppressing harmonic currents (ripple reduction)
2.Limiting surge currents during faults
3.Controlling the rate of rise of DC phase current
4.Enhancing power system dynamic stability

Critical Considerations
Indoor Installation:
Ventilation: Forced-air cooling (default) / Natural convection (customizable)
Ambient Requirements:
Dust level: ≤0.5 mg/m³ (non-conductive/explosive)
No corrosive gases (SO₂, H₂S, Cl₂ limits per IEC 60721-3-3)
Outdoor Installation:
UV-resistant silicone rubber insulators
Ice load withstand: Up to 20 mm radial ice (IEC 60071-2)
A smoothing reactor is an electrical component used to reduce current ripple in power systems. It stabilizes output by filtering fluctuations, improving efficiency and protecting equipment in applications such as rectifiers, inverters, and power supplies.
