摘　　要：针对泰安台DSQ水管仪在2020年的年中、年终标定中出现NS向多次重复标定均不合格的情况,通过分析标定过程中单端电压差值的变化,判断为标定装置中的水银掉落导致N端堵塞,经检修后标定合格。此次典型故障排查中分析电压差变化规律的方法,对台站水管仪的运行维护、标定故障识别有很好的借鉴和指导意义。The calibration of Tai'an DSQ water pipe instrument in the year-mid and year-end of 2020,there were many repeated calibrations in NS direction,which were unqualified.Analysis of the change of voltage difference in single terminal during calibration process,it is judged that the mercury in the calibration device fell,resulting in N-terminal blockage.The calibration is qualified after maintenance.In the process of typical fault investigation,the method of analyzing the variation law of single-ended voltage difference has a good reference and guiding significance for the operation and maintenance of station water pipe instrument and the identification of calibration fault.
