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”电压衰减而造成电源站不能启动的困难 DYZ power station is a kind of field station which is used together with SN36 8 and YKZ 480 Telemetry Digital Seismograph. When seismic exploration construction, it is connected in series with data acquisition and power supply. The article analyzes the working principle of the power station, and proposes an improved method of installing LEDs in the power station and improving the sensitivity of the “ghost pair” voltage detection. This method is simple and reliable, both in the field can quickly determine the power station is working properly, but also can overcome the “ghost pair” voltage decay caused by the power station can not start difficult
