新型变压器绕组及油面温度计Terman应用

Application of Terman,an Innovatlve Transformer Winding Temperature Indicator

变压器的使用寿命取决于它的绕组温度,有效地控制变压器绕组的热点温升,即可延长变压器的使用寿命,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检测较为常用的方法,分析检测方法的原理、优势及存在问题,并介绍特曼绕组温度计不同于市场上国际、国内设计的温度计的设计方法。为电力系统用户实际工作提供借鉴和帮助。

The service life of the transfromer is determined by its winding temperature. An effective control of the transformer＇s hot-spot temperature-rise can extend its service life, therefore, both large-sized and medium-sized transformers are equipped with winding temperature monitoring devices. This paper introduces conventional methods of monitoring the winding temperature of the transformer, and analyzes the theory, advantages and problems of those monitoring methods. The researcher also introduces the Terman winding temperature indicator, especially its unique design, different from the design of regular temperature indicator at home and abroad. This paper provides references and help in the actual work for the power system users.
