An open-close multi-working condition power distribution box shell for smart grid
PendingCN122292121AMulti-core performance collaborative optimizationPerfectly adapted to operational needsExtreme weatherSmart grid
This invention provides a hinged, multi-condition distribution box enclosure for smart grids, relating to the field of distribution box technology. It includes a distribution box cabinet with a fixed corrugated back panel on the back for enhanced wind pressure resistance. This provides stable anti-deformation support for the back of the cabinet during typhoon conditions, adapting to the extreme weather protection needs of islands. Both sides of the cabinet are equipped with side panel flipping mechanisms. This invention features flip-up side panels that can rotate 180° around a sliding pivot. Combined with the fixed corrugated back panel on the back of the cabinet, under extreme typhoon conditions, the corrugated flip panel can face outwards, forming a three-sided corrugated wind pressure-resistant structure to withstand typhoon impacts. Under normal conditions, the electromagnetic shielding layer can face outwards, avoiding the accumulation of salt crystals and hindering heat dissipation in the corrugated structure. This completely solves the industry pain point that fixed enclosures in island scenarios cannot simultaneously achieve wind pressure resistance, heat dissipation, and salt spray corrosion resistance.
