Abstract:Research purposes:With the rapid increase of power load application requirements of communication base station, repeater station, disaster prevention, signal relay station, auxiliary power of traction substation, switching station and other interzone, the number of 10/0.4 kV transformer is increasing consequently for those power loads, which aggrandizes the wastage of the transformer. For the purpose of reducing the wastage of existing transformers, this paper compares the annual power loss of amorphous alloy transformer with S11 transformer, calculates and contrasts TOC value of the two type transformer with comprehensive cost of energy efficiency method, which illustrates the energy conservation value of the amorphous alloy transformer. Research conclusions:(1) The no-load loss of amorphous alloy transformer is about 75% lower than S11 transformer, and the annual power loss of amorphous alloy transformer is about 30% less than S11 transformer; (2) The TOC value of amorphous alloy transformer is at least 20% less than S11 transformer; (3) With the increase of capacity, the TOC value difference between amorphous alloy transformer and S11 transformer is also increasing. (4) The amorphous alloy core transformer can be widely used in pole-mounted transformer, prefabricated substation,and indoor substation for railway power supply systems.
