摘　　要：针对大型变压器铁心与绕组故障多发的情况,以2台220 kV变压器为例,对变压器油箱表面振动信号进行测量,从而判断铁心与绕组运行状态,分析油箱表面不同位置处振动信号的特性,并提出了振动测量抗干扰措施。Windings and iron core often break down. Taking two 220 k V transformers as an example,the paper presents that the running status of windings and iron core can be diagnosed by measuring the vibration signals on the oil tank surface of transformer,analyzes the vibration characteristics of different locations for the transformers,also puts forward some anti-interference measures.
