摘　　要：电力主变压器是电力配送网络中的关键设备,也是导致电力系统事故最多的设备之一,变电站主变压器的运行状态直接影响供电安全水平。日常运行中为了降低主变压器对供电系统的影响,应当对主变压器采取系统的维护措施。通过对贵冶1#变电站3#主变压器内部故障的分析,找出故障发生的原因,并形成有针对性的维护措施,确保了主变压器的稳定运行。The main transformer is the key equipment in power distribution network, also is one of the equipment which most easily to cause the power system accidents. The operating state of main transformerin substation directly affect the level of power supply security.In order to reduce the influence to the main transformer on the power supply system, the maintenance measures of the main transformer should be taken in the daily operation.Through the analysis of the internal fault of 3# main transformer in 1# substation, the cause of the fault is found out and targeted maintenance measures are formed to ensure the stable operation of the main transformer.
