摘　　要：以永年地震台体应变洞温为实验对象,通过对永年台工作供电原理的深入分析研究,提出了把信号线路与供电线路隔离的方法,彻底解决电源交直流切换造成的数据畸变,经过现场实验,达到了预期效果。Taking temperature of the hole in Yongnian station as experiment subject in this paper,the principle of power supply to the precursor instrument is analyzed,and the method of disconnecting signal lines and power lines is proposed. This method completely solve the abnormal of data from the AC/DC switching. Depending the experiment in Yongnian station,it achieves the desired results.
