摘要
牵引变电所是电气化铁路供电系统的心脏,是发电厂到电力机车之间的重要环节之一,主要由牵引变压器和相应的配电装置构成。牵引变压器的作用是将1 10 kV(220 kV)的三相交流电变换成27.5 kV(55 kV)的单相交流电。变压器的运行是否安全可靠,关系着牵引供电系统能否正常运行工作。因此,牵引变压器运行维护必须合理,尽可能消除或减少故障,提高牵引变压器运行的可靠性。分析牵引变压器的常见故障和产生原因,研究状态监测的现状和存在的问题,对于牵引变压器运行维护有一定的现实意义。
The traction substation of electrified railway traction power supply system of the heart, 1s one ot the important nnK oetween me power plant to the electric locomotive, traction transformer and distribution device is mainly composed of thecomposition of the corresponding. Traction transformer is the role of the 110 kV（ 220 kV ）three-phase alternating current into a 27.5 kV（ 55 kV ）of single-phase alternating current. Transformer operation is safe and reliable, the traction power supply system whether normal operation. Therefore, the traction transformer operation and maintenance must be reasonable, as far as possible to eliminate or reduce the fault, improve the reliability of traction transformer operation. Analysis of traction transformer fault and cause, condition monitoring research and existing problems, for the traction transformer operation and maintenance has certain practical significance.
