摘要: 变压器的使用寿命取决于它的绕组温度。绕组温度对绝缘材料的温度和老化起着决定性的作用,故在大、中型变压器上都配备了绕组温度监测装置,介绍了变压器绕组温度计工作原理。监测装置须可靠,若变压器超出允许温度或监测装置不准确时,会影响变压器的正常运行,论述了使用绕组温度计应注意的事项。

Abstract: The transformer lifespan depends on its winding temperature. The winding temperature has decisive function to insulating material temperature aging, therefore, the winding temperature measurement devices are allocated in large and medium transformer. The principle of thermometer for transformer winding was presented. The supervisory instrument must be reliable, the over temperature of transformer winding and over tolerance of supervisory instrument will influence the transformer normal operation. The matters needing attention in using of thermometer for winding were expounded.
