    • PROBLEM TO BE SOLVED: To provide a copper wire softening device which can stably soften a copper wire over a wide range from a low speed region to a high speed region.SOLUTION: A copper wire 2 is traversed on first to third electrode sheaves 31 to 33, and the copper wire 2 is moved while contacting with them. A power source unit 2 supplies ac voltage between the first electrode sheave 31 and the second electrode sheave 32 and between the second electrode sheave 32 and the third electrode sheave 33, and the copper wire 2 moving in contact with them is energized and softened. The power source unit 2 includes an inverter, the inverter having: a converter part which converts ac voltage into dc voltage; and an inverter part which converts, into ac voltage, the dc voltage which the converter part converted.
    • 要解决的问题:提供一种铜线软化装置,其可以在从低速区域到高速区域的宽范围内稳定地软化铜线。解决方案:铜线2在第一至第三电极滑轮31上穿过, 33,铜线2与它们接触时移动。 电源单元2在第一电极滑轮31和第二电极滑轮32之间以及第二电极滑轮32和第三电极滑轮33之间提供交流电压,并且与它们接触移动的铜线2被通电并软化。 电源单元2包括逆变器,所述逆变器具有:转换器部分,其将交流电压转换为直流电压; 以及将转换器部分转换成的直流电压转换为交流电压的逆变器部分。
