摘要
DYZ电源站是与SN36 8和YKZ 480遥测数控地震仪配套使用的一种野外站体 ,地震勘探施工时串接在数据采集排列中 ,给排列上的采集站供电。文章分析了电源站的工作原理 ,提出了在电源站内加装发光二极管和提高“鬼对”电压检测灵敏度的改进方法。此方法简单可靠 ,既可在野外迅速判断电源站是否正常工作 ,又可以克服因存在“鬼对”
DYZ is used with SN368 and YKZ 480.It supplies power for the acquisition station when being linked in series in spread.The paper analyses the operation principle of DYZ and offers the methods of improving DYZ.We can rapidly check whether DYZ work well and slove the problem of DYZ no working due to the large attenuation of the ghost voltage in spread.
