摘要
本文分析了低压抽出式配电柜水平母线两种布置形式对柜体结构、电气性能、柜体温升的影响；通过数学推导求出了在大电流条件下水平母线横跨的钢结构由于涡流感应引起温升的数值；得出了水平母线布置为顶装式的柜体温升较小的结论。
The author analyzes the effects caused by two fixing models of horizontal bus bars in modular low voltage switch gear system to cabinet structure,electrical performance and temperature rise of cabinet,works out the date of temperature rise of steel mernbers which acrossed heavy current bus bars due to eddy current effect by mathematical method,and comes to the conclusion that the temperature rise of cabinet is lower when the horizontal bus bars are fixed in the top of cabinet
