与将多个电流信号切换至单台安培表不同，将一个电流源切换至多个负载通常不需要任何时候到维持电流通路的连续性。
Unlike switching current signals to an ammeter, switching a current source to multiple loads usually does not require maintaining the current path at all times.
计算结果表明：三相次级整流电阻焊焊接电流基本上是连续的，负载感抗变化对其影响很小。
The calculating result shows that the welding current of 3-phase DC resistance weld is continuous, and the changing of induction reactance has little influence on it.
