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

 

Output Reactor

New Energy Power Generation

Improves grid connection efficiency and protects equipment.

DC Reactor

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.

Load Reactor

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.

Pure Copper Wound Reactor

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.

FAQ

 

Q: What is a DC reactor used for?

A: It suppresses current fluctuations and harmonics, protects equipment (such as photovoltaic inverters and motor drives), and improves system stability.

Q: How to choose a model?

A: Consider three key parameters:
Rated current: Choose a model at least 20% higher than the system's maximum current.
Voltage level: Match the system's DC voltage (e.g., for an 800V system, choose a reactor ≥1000V).
Inductance: Calculate based on harmonic suppression requirements (e.g., suppressing the fifth harmonic requires a specific value).

Q: What precautions should be taken during installation?

A: Proper ventilation: Do not block heat dissipation holes to avoid high temperatures.
Moisture and dust resistance: For indoor use, choose a model with an IP rating of IP54 or higher.
Wiring: Connect the positive and negative poles as indicated. Do not reverse or short-circuit.
