| Abstract: | The background and the course of overhaul for 15,600 kVA rectification transformer were narrated,which was imported and in a Heat Rolling Mill.The paper discussed the reason of tap changing switch fault,introduced the structural characteristics of this kind of rectification transformer. The suggestion for no-load tap changing switch in overload operation is put forward,if it is not used for a long period,the tap changing switch can not be adopted. |
