工厂电力负荷设计中变压器台数和经济容量的选择

How of Select Quantity and Economic Capacity of Transformer in the Design of Factory Electric Power Loads

本文根据负荷等级、电压类别、负荷特点、变压器安装场地条件和低压设备断流能力等方面,提出变压器台数的选择原则。并在变压器静态经济负载率分析的基础上提出变压器动态最佳负载率,以此作为变压器经济容量的选择依据。

The principles for selection of transformer quantity are provided in the light of load degress, voltage levels, load properties, installing condition of sites, breaking capacity of low voltage equipments etc. On the basis of the analysis of static economic load rate, a dynamic optimal economic load rate of transformer is provided, which is the basis for selection of trans-former capacity.
