【摘要】 封闭母线是进行电力传输的重要载体,封闭母线的发热损耗一直是困扰着电能运输及有效利用的重要问题。从封闭母线发热的角度出发,建立热平衡方程,计算分析强迫风冷封闭母线的温升规律,为强迫风冷在大功率大电流封闭母线中的应用提供了有力的理论支持。更多还原

【Abstract】 The enclosed bus-bar is the important equipment in the power transmission.The heat dissipation of the bus-bar is a significant problem affecting the power transmission and effective exploitation.This paper has created the heat balance equation and analyzed the temperature rising law of forced air-cooled enclosed bus-bar mainly from the perspective of generating heat.The theoretical supports are provided for the appliance of the forced air-cooled means on the high power and great current enclosed bus-bar.更多还原
