摘要
通过对陕西地震前兆台网4个地震台的ZD9A-Ⅱ地电场仪的观测资料进行了分析,对该仪器的各项工作指标、观测记录的数据甄别出异常变化形态,找出观测过程中存在的主要问题和故障现象,分析发生仪器故障的原因及处理方法;对有关的电路及故障原因进行分析,并以实例对这些故障的检修进行了总结,提出了检修方法、步骤及改进措施。
By studying observational data of ZD9A-II geoelectrical observation apparatus from 4 seismic stations of seismic precursor network in Shaanxi,abnormal change forms are discriminated according to work indexes and recorded observation data,main problems and failures in the observation are found out,and causes and measures of instrument failures are analyzed.Maintenance methods,steps and improvement measures are proposed according to analysis on related causes for electric circuits,failures and conclusion of maintenances by the practical examples.
