摘　　要：针对油浸式变压器绕组测温装置运行时两表偏差较大以及远方监视中断等问题,通过对测温原理及综合因素的分析,阐述了一种通过采用独立式温度转换模块并更改测温接线方式以消除缺陷的改进措施,进一步提高了远方测温的精确度。In order to solve the great differences of two tables deviation in oil-immersed transformer winding temperature as well as the interruption of remote monitoring, an improved measure, which can eliminate defects by applying independent temperature conversion module and by changing the ways of temperature-measuring connections, is put forward. It is elaborated on basis of the analysis on temperature-measuring principles and integrated factors for the sake of further improving the accuracy of remote temperature measurement.
