It is because of the existence of the nonlinear inductor that the instantaneous working state of the weldingtransformer is hardly to be analyzed with classical electrotechnical theory.
正是由于非线性电感的存在,造成难以用经典的电工学公式适时分析焊接变压器的工作状况。

Transformers: it is used by water-cooled weldingtransformer with single-phase 200kva vacuum epoxy encapsulation. It accounts for more than 50% load.
变压器:采用单相200kva真空环氧封装水冷式焊接变压器,占载率50%以上。

It shows that the numerical simulation is an effective method to analyze and design weldingtransformer. It is the base of optimization design of welding machine.
