APPARATUS AND METHOD FOR MITIGATING THERMAL EXCURSIONS IN AIR CORE REACTORS DUE TO WIND EFFECTS

摘要

An air core, dry type, power reactor (10) of the type having multiple concentrically positioned winding layers (12) extending along a central axis and above arms (24) of a first spider unit (16) when the reactor is horizontally positioned with respect to a horizontal ground plane, the winding layers (12) arranged in spaced-apart relation providing air gaps (20) between the winding layers allowing air to flow along the winding layers. A deflector (40) is positioned between the winding layers (12) and the ground plane to receive air from wind blowing toward the reactor (10) and guide the air in an upward direction from the deflector (40) and along the gaps (20).
