侯月线主变压器过负荷分析及对策

本文在分析侯月线牵引变电所主变压器过负荷状况和原因的基础上,提出了解决该问题的对策.认为变压器过负荷有多种情况,如变压器负荷电流增大、变压器输出电压降低、变压器温度上升等.可通过合理排放车流、加强变压器散热和温度监测、定期切换变压器和适当提高变压器过负荷倍数等方法抑制变压器过负荷.

Analysis of Main Transformer Overload at Houyue Railway Line and Its Counter-measures

Based on the analysis of the condition and causes of transformer overload in traction substation of Hou-Yue line, this paper obtained the counterplans to resolve the problem. This article thought that the transformer overload has had many kinds of situations, like the transformer load current increases, the transformer output voltage to reduce, the transformer temperature rise and so on. These methods can be taken to alleviate the transformer overload, for example, reasonable traffic emissions, to strengthen transformer cooling and temperature monitoring, periodic switching transformers, to enhance the transformer load multiple suitably, etc.
