摘要
对甘肃武威南营地电场正常和异常情况的波形特征进行了对比分析,就2018年3月10日出现的数据异常状态,通过主、备用观测仪器的并行观测,固体不极化电极的更换以及观测线路的替换等方法,最终找出此次故障是由于测量外线路氧化虚接造成,按照规范进行了相关处理后,观测数据恢复了正常。此次故障排除过程,可以为地电场观测台站的观测故障判定及排除提供一种思路和方法,逐步提高地电场观测资料的质量,为地震前兆研究提供可靠的观测数据。
The waveform characteristics of normal and abnormal electric field of Wuwei Nanying in Gansu province were compared and analyzed. For the abnormal data on March 10,2018, it is analyzed the abnormal by the main, standby observation instrument of the parallel observation, the solid-impolarized electrode replacement, as well as observation line replacement methods, and found that the fault is due to the measurement of the external line oxidation caused by the specification of the relevant treatment, the observation data returned to normal. The process of troubleshooting can provide a kind of thinking and method to judge and eliminate the observation fault of the earth electric field observation station and improve the quality of the observation data of the geo-electric field and provide reliable observation data for the earthquake precursor research.
