12kV干燥空气柜环保型绝缘模型设计OA

As the distribution network industry evolves towards greener and low-carbon solutions,environmentally friendly gases are progressively substituting traditional SF6 gas as the insulation medium for medium-voltage inflatable cabinets.Given the limitations associated with the insulation efficacy of currently used environmentally friendly gases and the challenges related to the sustainable recycling of epoxy resin insulation components,this paper introduces an environmentally friendly insulation model that utilizes thermoplastic materials and integrated injection molding technology,specifically applied to 12kV dry air insulated inflatable cabinets.Through mechanical simulations,the study confirms that the mechanical properties of the proposed insulation model meet the required standards.Additionally,electric field simulations optimize the insulation model's structure,effectively reducing the localized maximum electric field intensity and enhancing insulation performance.Finally,the insulation reliability of the environmentally friendly insulation model is substantiated through comprehensive insulation test and partial discharge assessments.
