Main functions of a reactor
Current Limitation
Reactors can limit the rate of change of current to prevent sudden increases or decreases in current, thereby protecting equipment in the power system from current shocks.
Voltage Stabilization
Reactors can stabilize voltage, especially during sudden changes in power system loads or transient faults, helping to maintain the system's voltage levels.
Harmonic Filtering
Reactors can be used to filter out harmonics in the power grid, reducing harmonic pollution in the power system and protecting equipment from the effects of harmonics.
Short-Circuit Current Limitation
Reactors can limit short-circuit currents in the power grid to prevent equipment damage during faults.
Power Factor Improvement
Reactors can improve the power factor by compensating for reactive power back to the grid, increasing the power factor of the power grid, and reducing energy wastage.
Power System Stability
Proper use of reactors in a power system can enhance system stability, reducing issues such as voltage dips and excessive currents.
Application Scenarios of Reactor

New Energy Power Generation
Improves grid connection efficiency and protects equipment.

Photovoltaic Inverters
Problem: Fluctuating sunlight causes high current harmonics (THD up to 15%–20%), reducing inverter efficiency.
Purpose: Filters harmonics to reduce current ripple below 3%, improving efficiency by 1.5%–2.3%.
Industrial Drives:Extends equipment life and reduces maintenance costs.

High-Voltage Inverters
Problem: PWM harmonics lead to motor overheating, insulation degradation, and accelerated bearing wear.
Purpose: Harmonic suppression reduces THD from 25% to 5%, lowering motor temperature rise by 5–8°C.

Rail Transit
Ensures power supply security and improves energy efficiency.
Metro Braking Energy Regeneration
Problem: DC bus voltage surges (up to 1800V) during train braking, threatening equipment safety.
Purpose: Smoothes current peaks and, combined with energy storage, achieves 18% energy savings.
Process Technology And Customization Services
Advanced Manufacturing Process
Laser Welding Technology: The resistor wire and terminals are laser-welded, achieving a contact resistance of less than 0.5 mΩ, reducing heat loss.
