摘要

V12热敏绘图仪是地震勘探仪器最常用的标准配置设备之一,是野外施工现场重要的质量监控设备。电源电路是其故障高发部件,却没有带电路图。结合V12热敏绘图仪电源的维修,笔者绘制了一份电路图,并详尽地阐述了V12热敏绘图仪+24V电源电路工作原理,给出一个维修实例。
V12 thermal plotter is one of the most commonly used auxiliary equipments in seismic exploration, also it is one of the important quality monitoring equipments in-site. Since the power circuit of v12 plotter is a part esay to be in failure, and the manufactuer never provide the power circuit scheme, so in combination with many years practical maintenance experiences, the author of this paper draw out the circuit scheme. This paper introduces the working theory of this circuit in detail and gives an example for troubleshooting.
