Air core reactors are primarily used in power systems for limiting short-circuit currents, reactive power compensation, and phase-shifting. Magnetic flux forms a circuit through air, hence they are called air core reactors.
Characteristics:
1. Oil-free structure eliminates the drawbacks of oil-immersed reactors such as oil leakage and flammability, ensuring operational safety. Without an iron core, there is no magnetic saturation, ensuring good linearity of inductance.
2. Computer-aided optimization design for dry-type air-core reactors allows rapid and accurate design of the ideal structural parameters according to different user requirements.
3. Utilizes a cylindrical structure with multiple layers of parallel windings, each section interconnected with ventilated ducts for great heat dissipation and low hotspot temperatures.
4. Windings use small cross-section round conductors wound in parallel strands, significantly reducing eddy current and stray magnetic losses.
5. External windings are tightly sealed with impregnated epoxy resin and fiberglass, cured at high temperatures for high mechanical strength and strong tolerance to short-duration current impacts.
6. Uses high-strength aluminum star-shaped terminal blocks to minimize eddy current losses.
7. Special anti-UV aging protection coating is applied to the entire inner and outer surfaces of the air core reactor, ensuring strong adhesion and resilience to harsh outdoor weather conditions.
8. Installation can be vertical for three-phase, or in a zigzag or linear configuration, significantly reducing infrastructure investment for outdoor use.
9. Operates safely with low noise levels and requires minimal maintenance.
10. Inductance can be made adjustable according to user requirements, with an adjustable range of up to 5% or more.
