摘　　要：电力设备中最重要的是电力变压器,它的功能是变换电压,传输分配电能。要确保电力系统安好,健康运转,必须减少和防止变压器发生故障,产生事故。近几年,电力故障已层出不穷,但如果某些故障导致大的电力事故,不仅会给供电公司和社会造成很大损失,也会对人身安全造成威胁。变压器长时间运转,发生故障在所难免,而引发这些故障的原因也来自多方面因素,如电力变压器长时间运作导致设备老化,外力破坏和自然灾害,制造、安装、维修过程中遗留下的问题或者工作人员作业时的疏忽。所以,要针对产生的故障进行分析,作出必要的技术改进。The most important power equipment is the power transformer,its function is to transform the voltage,transmission and distribution of electrical energy.To ensure the safety and healthy operation of the power system,transformer failures and accidents must be reduced and prevented.In recent years,the failures that have occurred have occurred one after another,but if some failures lead to major power accidents,it will not only cause great losses to the power supply company and society,but also threaten personal safety.Faults are inevitable when the transformer runs for a long time,and the causes of these faults also come from many factors,such as longterm operation of the power transformer,which leads to equipment aging and shortened life;from external damage and natural disasters and during manufacturing,installation,and maintenance The remaining problems or the negligence of the staff when working.Therefore,we must analyze the generated faults and make necessary technical improvements.
