描述了一种计算IEC 61660-1中所述发电厂和变电站直流辅助装置中短路电流对刚性导体产生的机械和热效应的方法。 提供了一种应用广泛且结果足够准确的方法。计算方法基于代换函数，代换函数在导体中产生与实际电磁力大致相同的最大应力，在支架上产生与实际电磁力相同的力。

Describes a method for calculation of the mechanical and thermal effects on rigid conductors caused by short-circuit currents in d.c. auxilliary installations in power plants and substations, as described in IEC 61660-1. Provides a method which has wide application and which gives results of sufficient accuracy. The calculation method is based on substitute functions, which cause approximately the same maximum stresses in the conductors and the same forces on the supports as the actual electromagnetic force.
