Reform of High Loss Agricultural Transformer
Zhen Zhao · Journal of Langfang Teachers College · 2001
By using the principles of transformer and taking into consideration of the operating characteristics of transformer,it is found after calculation and analysis that the 64 Standard transformer,after its iron core is replaced,its volume is reduced nearly a degree,but its operation loss at low load rate is lower than that of 86 standard transformer with the same volume.After studying the volume difference before and after the coil is replaced in the 73 Standard transformer,it is discovered with calculation that,though the copper for copper coil reform scheme reduces greatly the volume,its energy saving effect of operating under 1/4 low load is obvious,whereas the aluminium for copper reform can not only keep the volume unchanged,but also achieve good energy saving effect even when the agricultural transformer operates at low load rate.
