摘要
本文介绍了一例换流变压器绕组温度测量回路的故障事件,通过阐述绕组温度测量原理,分析了测量回路故障原因。最后提出了类似故障再次发生时的处理建议,以及对绕组温度测量回路的改进措施。
The winding temperature of converter transformer is an important indicator reflecting its operating conditions. Therefore, the measurement and real time monitoring of winding temperature is cruciaL An indirect method of measuring the winding temperature is currently in common use. This paper introduces a fault event, of winding temperature measuring circuit for converter transformer. By explaining the principle of winding temperature measurement, the cause of fault in measuring circuit is analyzed. Finally, suggestions for handling similar faults, as well as measures for improving the measuring circuit, are put forward.
