摘要
遥测地震仪的维修工作主要集中在采集站电路,而各种仪器的采集站又各不相同。文章利用有限的资料,针对MYRIASEISⅡ仪器的维修重点之一TSU的电源电路进行了系统的分析,阐述了其电路特点,从而为TSU的维修工作提供了十分有益的帮助。另外,在总结实践经验的基础上,对其电路的不足之处加以说明。
Most of the troubleshootings concerns of telemetry seismic instrument concentrate on seismic data acquisition unit (SU) circuit' But SUs in various instruments are different frorn each other. With the help of only limited material, this article analyzed systematically MYRIASEIS Ⅱ TSU power circuit -one of the key maintenance work -and described its characteristics. It will be a great help to TSU maintenance. In addition, based on practical experience, the article pointed out its circuit design defects'
