6-110kV high voltage Dry type air core reactor

Compared with the dry iron core reactor and oil immersed reactor, what are advantages of the dry air core reactor?

1. The oil-free structure eliminates the shortcomings of oil leakage and flammability of oil immersed reactor, and ensures the operation safety. No iron core, no ferromagnetic saturation, good linearity of inductance value;

2. The optimal design of dry-type air core reactor by computer can quickly and accurately design the most ideal structural parameters according to different user requirements;

3. The cylindrical structure with multilayer windings in parallel is adopted, and there is a ventilation duct between the envelopes, which has good heat dissipation and low hot spot temperature;

4. The winding adopts the parallel winding of multiple strands of small cross-section round conductor, which can significantly reduce the eddy current loss and magnetic leakage loss;

5. The outside of the winding is tightly wrapped with glass fiber impregnated with epoxy resin and cured at high temperature to make it have good integrity, high mechanical strength and strong resistance to the impact of short-time current;

6. Aluminum star shaped connection frame with high mechanical strength is adopted, with small eddy current loss;

7. The whole inner and outer surfaces of the air core reactor are coated with a special anti ultraviolet and anti-aging protective layer, which has strong adhesion and can withstand the harsh outdoor weather conditions;

8. The installation mode can be three-phase vertical, or word or straight line; Outdoor use can greatly reduce infrastructure investment;

9. Safe operation, low noise, no need for regular maintenance;

10. According to the user's requirements, its inductance can be made adjustable, and the adjustment range can reach 5% or more.

Of course, the dry air core reactor has some disadvantages compared with oil immersed and epoxy resin iron core reactors, mainly due to its large floor area, magnetic leakage, high noise and high loss. If it is used outdoors in an open space, it will not affect the normal activities of humans and animals. It is also a good choice to choose a dry air core reactor with high cost performance.
