摘要
变压器绕组温度的监测问题已日益受到重视,由于测温场合条件特殊,直接或间接检测绕组温度一直是一个难题。在寻求温度传感器的其他替代手段的所有研究中,光纤测温以其抗电磁干扰能力强、体积小、耐高压、耐腐蚀等优点逐步受到重视。根据变压器绕组测温的实际情况提出一种简单可行的测温新方法,即基于半导体吸收式的光纤测温技术。试验结果表明了该方法应用于变压器绕组温度在线监测的可行性。
The monitor of transformer winding temperature has temperature has always been a difficult problem for it＇s special been regarded day by day. Direct or indirect check of winding temperature measurement condition. In the study of looking for substitute measure, optical-fiber temperature measurement has been given more and more attention for its advantages of strong resistance of electro-magnetic interference, small volume, high-voltage resistance and corrosion resistance. In accordance with the real condition of transformer winding temperature measurement, a new simple and feasible method is put forward, i.e. semiconductor absorption based optical-fiber temperature measurement technology. Test results show the feasibility to apply this new method in transformer winding temperature measurement.
