摘　　要：以双绕组矩形线圈的单相电阻焊变压器为例总结了采用相对漏磁链计算变压器电抗电压的步骤和计算公式。采用相对漏磁链方法计算了一台四绕组矩形线圈单相电阻焊变压器在改变一、二次侧边绕组位置时的电抗电压。计算结果表明,在使用相同原材料,不增加工艺复杂性的情况下,通过绕组位置的合理分布有效减少了电阻焊变压器的漏磁,增加了电阻焊机的有功输出,可以提高生产率,同时减少电阻焊变压器的能量损失。RRectangular co il with double winding single-phase resistance welding transformer as an example, summed up with relative leakage flux of transformer reactance voltage steps and calculation formula.Relative leakage flux method to calculate the four winding a rectangular single-phase resistance welding transformer coil changing position the reactance of the primary and secondary side winding voltage.Calculation results show that when using the same raw material, does not increase the complexity of process conditions, through the reasonable distribution of the winding position effectively reduce the resistance welding transformer magnetic flux leakage, increase the active output resistance welding machine, can improve productivity, reduce the energy loss of resistance welding transformer at the same time.
