Description
Technical field
The utility model relates to a kind of high-power power supply structures of thyristor rectifier digitial controller.
Background technique
Currently, electrolysis series electric current reaches 660kA, potline current grade in 500kA or more, or even some at present
Higher and higher, alternating current magnetic field, D.C. magnetic field follow more and more by force, and existing thyristor rectifier digitial controller working power is by magnetic field
Influence causes failure rate constantly to occur, it is difficult to ensure that electrolytic cell stable power-supplying.
Leading to the higher factor of digitial controller failure rate is exactly that the diamagnetic field energy power of its working power is poor.In under high-intensity magnetic field
Set that Switching Power Supply power is small to be influenced big by high-intensity magnetic field, it is electric that digitial controller working power is changed to external high power switch by scene
Source, enhances the diamagnetic field energy power of power supply, the operation stability of the equipment greatly improved, and the work being able to satisfy under high-intensity magnetic field completely is wanted
It asks.
