漓渚铁矿阮江变电所原设计采用通常的两条35kV线路同时供电、6kV母线分列运行的供电方式。这种方式既安全又经济。但由于1972年投产时35kV线路只建成一条,故只能采用单回路供电的运行方式。两年后,另一条35kV线路虽然建成,但6kV负荷情况有了变化,即新增1台容量为1200kVA的1.5t电炉。新增出线间隔由6kVII段母线供电。如采用原设计供电方式,则在开电炉时2号主变将超出额定电流的15～20％;在两台主变并联 The Nguyenjiang Substation of Lizhu Iron Mine was originally designed to supply power from two common 35kV lines at the same time. This method is safe and economical. However, due to put into operation in 1972 35kV lines built only one, it can only use a single loop power supply operation. Two years later, another 35kV line was completed, but the load of 6kV had changed. That is, an additional 1.5t EAF with a capacity of 1200kVA was added. The new outlet interval by 6kVII busbar power supply. If the original design of power supply, then when the furnace on the 2nd main transformer will exceed the rated current of 15 to 20%; in the two main transformer in parallel
