非晶合金变压器及其在成都地铁30号线的应用

Amorphous Alloy Transformer and its Application in Line 30 of Chengdu Metro

目前城市轨道交通配电变压器负载率约为30%,长期处于轻载状态,电能浪费严重。非晶合金变压器空载损耗仅约为常规配电变压器的30%,低能耗优点突出,可充分节约运营成本。本文将非晶合金变压器与常规配电变压器进行对比分析,结合成都地铁30号线进行经济性分析,为后续城市轨道交通线路设备选型和节能提供参考。

The load rate of distribution transformers for urban rail transit is about 30%at present,they are in a light-duty state and causes severe waste of electricity in a long term.The no-load loss of amorphous alloy transformer is only 30%of that of conventional distribution transformer,it is advantageous in energy consumption and it is able to decrease the operational costs.The paper compares the amorphous transformer with the conventional distribution transformer,carries out the economical analyzing with connection to the line 30 of Chengdu Metro,providing references for selection of types of equipment and energy-saving for consequent urban rail transit lines in the future.
