建筑电气设计中的等效负荷计算分析与探讨

现行有关电气设计参考书和工程上对线间负荷等效为三相负荷的计算均按建设部颁发的电气设计规范中的规定执行,但是规范中并未对线间负荷的功率因数是否相等作明确规定.通过理论计算和分析,提出了在功率因数相等和不相等两种情况下,线间负荷等效为三相负荷的计算公式.

Analysis and Discussion on Calculating the Equivalent Load in the Design of the Architecture Electric

The calculation of the line-to-line load is equivalent to the three-phase load, which are applied in electrical design reference and engineering, are carried out by the specification of electric design which issued by the Ministry of Construction in China. But there has not definitely declared whether the power factors of line-to-line load are equal or not. By theoretical calculation and analysis, the calculation formulas of the line-to-line load was equivalent to the three-phase load under two conditions that power factors were equal or not were put forward respectively.
