摘要
周期（２π） 换向金电解精炼电源，由２ 只硅整流管及１ 只可控硅组成，可将单相交流电的波形变成适于金电解的周期换向电流波形。它的各方面性能都优于传统的沃耳维尔（Ｗｏｈｌｗｉｌｌ） 交直流叠加法和改进后的交直流叠加法。金电解精炼电流效率可达９３ ％ ～９５％ ，电金成色达９９－９９ ％ 。
The power supply of cyclic(2π) change over electrorefining of gold is composed of a couple of silicon rectifiers and a controlled silicon.It can change the wave form of single phase alternating current into the wave form of cyclic change over current which is suitable for gold electrorefining.Its performance is superior in every aspects to the traditional Wohlwill super inposition of a-c and d-c as well as reformed superimposition of a-c and d-c.The current efficiency of gold electrorefining if able to reach 93%-95%.The fineness of electrorefined gold comes to 99 99%.
