变压器的容量选择及并联投切临界电流

Selecting the Capacity of Transfomcr and the Critical Current When Making its Parallel Connection to Certainly Invested in Em-ployment

在选择变压器容量时宜按“计算经济负荷率(β_(30.ec))”进行计算,而在决定并联变压器是否投切时,则按“运行经济负荷率(β_(ec))”计算投切临界电流,文中叙述了这两种负荷率的区别和应用,并由此导出了确定变压器容量的计算式,以及并联投切临界电流的计算式.

When selecting the capacity of transfomer making calculation that should be considered that called 'load factor of calculated economics (β_(30.cc))'of the time factor, and deciding parallel transfomers whether or not certainly invested in employment, when transfomer had run, We ought to according to 'load factor of calculated economics' to calculated the critical current which certainly invested in employment. This article stated the difference between the two load factors and it's application, and therefore We derived the formula for deciding the capacity of transfomer; and the formula of critical current When making its parallel connection to certainly invested in employment.
