“12脉”中频炉是最好的选择？

“12脉”中频炉是最好的选择？ 有以下优点：

1.省电快速，与串联电路中频炉炉几乎一样；

2.无谐波产生；

3.比其它电路更成熟稳定，故障率低；

4.维修人员相对更多；任何人都会维修。

5.元器件便宜；

6.全套设备价格相对便宜；

缺点有一个：对变压器有特殊要求，要求电源变压器有6相7线输出；

Is the "12-pulse" induction melting furnace the best choice?

Is the "12-pulse" induction melting furnace the best choice? Has the following advantages:

1. Fast power saving, almost the same as the series circuit induction melting furnace;

2. No harmonic generation;

3. It is more mature and stable than other circuits, and has a low failure rate;

4. There are relatively more maintenance personnel; anyone can do maintenance.

5. The components are cheap;

6. The price of a complete set of equipment is relatively cheap;

There is one disadvantage: there are special requirements for the transformer, requiring the power transformer to have 6-phase 7-wire output;
