摘要：

摘要：变压器是电力系统中的重要设备，运行中需要对其运行温度进行不间断监测。针对变压器上多个测温装置显示的温度偏差过大的情况，以某发电厂主变压器为例，对目前变压器常用的3种测温装置进行测温对比试验，指出测温误差产生的原因为机械式温度表动作不灵敏，并提出了相应的安装调整措施。

Abstract:

Abstract:A transformer is an important facility in the power system and its operation temperature should be continuous monitored. For the large temperature measuring deviation problem of some temperature measuring devices on the transformer and taking the main transformer of a certain power plant as an example, this paper conducted a temperature measuring comparison test on three common temperature measuring devices. It pointed out that the cause of temperature measuring error was the insensitivity of mechanical thermometer and proposed corresponding installation adjustment measures.
