INTEGRATED SOUND SHIELD FOR AIR CORE REACTOR

摘要

An air core power reactor (10) having a noise mitigating sound shield (40). In one embodiment the sound shield includes a plurality of sound absorbing panels (42p) configured for positioning about an outermost reactor layer (12′) so that the panels reduce radiation of acoustic energy when the reactor coil layers carry current. One or more flexible members (48) are attached along the first side of each sound absorbing panel for contact with the outermost reactor layer. Sound barrier material (44) is positioned along the second side of each panel. When the flexible members are attached to a panel and the panel is installed about the outermost first layer of the reactor, the flexible members are positioned against the outermost first layer and the flexible members provide a gap between the first side of the panel and the outermost first layer of the reactor.

主权项

1. An air core dry type power reactor comprising:
upper and lower spider units each comprising a plurality of support arms extending radially outward from a central axis; a plurality of cylindrically shaped layers concentrically positioned about one another and with respect to the central axis, some of the layers being winding layers arranged in spaced-apart relation from one another to provide gaps between some of the winding layers to allow air to flow along and between winding layers, the plurality of layers including an outermost first layer; a sound shield positioned against the outermost first layer comprising (i) a layer of sound absorbing material extending around the outermost first layer, (ii) a layer of sound barrier material also extending around the outermost first layer, and (iii) a plurality of flexible members each positioned between the sound absorbing material and the outermost first layer.
