可控硅的应用现在已经是非常普遍了。我厂将可控硅应用到热处理车间的三相盐炉上是1973年开始的。当时对这件事物用到有变压器的盐炉上,是有许多疑问的。首先是三相大功率变压器接成△,据资料上介绍在导通角小的时候,磁路不成回路。变压器要发热。其次在原理上用改变导通角控制电流的电路是要产生干扰讯号的,对其他设备及变电所是有影响的。但是这些问题有多大危 Thyristor applications are now very common. I plant will SCR applied to the heat treatment plant three-phase salt stove was started in 1973. At the time, there was a lot of doubt about the use of salt stoves with transformers for this matter. The first is the three-phase high-power transformer connected into △, according to the information presented in the conduction angle is small, the magnetic circuit can not be a loop. Transformer to heat. Second, the principle of changing the conduction angle to change the current control circuit is to generate interference signals, and other equipment and substations are affected. But how serious are these problems?
