脉冲编码遥测仪电源电路设计缺陷的改进
资料介绍
在测井井下仪故障频次统计中得出，由于电源故障，导致MBY—IB脉冲编码遥测井下仪电路中，数字线路板APl板、模拟线路板AP2板、脉冲线路板AP3板电子器件损毁的现象屡见不鲜，究其原因，是因为工作电源中的TO一3金属封装的LM7815、LM7915与LM7805损毁而引起的。对电源电路进行分析发现该电路存在设计缺陷。
Based on the failure frequency statistics of downhole logging tool,it is derived that the electron device damage is common occurrence in the circuit of MBY-IB pulse encoding telemetry,digital circuit board AP 1,analog line board AP 2and impulse circuit board AP 3which is caused by power failure.The reason is because the LM7815,LM7915and LM7805encapsulated by TO-3metal in power supply are damaged.It is found that there is a flaw in circuit design through analysis of the power supply circuit.
