矿山准轨牵引变电所容量的确定

DETERMINATION OF THE SUBSTATION CAPACITY FOR MINE STANDARD GAGE TRACTION

本文详细叙述了用经验系数法计算最大短时负荷所用公式的演变过程和修正,并对如何正确使用分析法确定最大短时负荷作了说明。通过对一些矿山准轨牵引变电所容量的验算和比较,表明所提出的公式具有较强的实用性。

In this paper,through a great amount of investigation,analyses and research,the auther gives a relatively allsided description of the method determining the substation capacity for standard gage traction in metallurgical open pit mine. Formulas calculating the mean load of substation for traction and the maximum transient load of substation for traction are introduced. Development and correction of formula, calculating the maximum transient load by emperic coefficient method are described in detail, and correct determination of maximum transient load by analysis method is explained. Through check and comparation , the formulas are proved practical.
