摘要
该电路首先是满足直流电场提高采收率技术的用电要求，选取目标电压为直流电场提高油田采收率技术中数值模拟出的效果最佳作用电压150V。其次对现有直流电源进行改进。主要针对原有电源电路的稳压环节进行改进。利用低电压普通集成稳压器LM317设计精密稳压的150V直流稳压电路，电路采用两个NPN晶体管实现了LM317输入、输出端之间的限压、稳压和输入端的限流，电路具有较高的稳压精度。
The optimum 150V（DC） was designed to improve oil recovery via DC electric field;then the voltage regulation of existing DC power was improved,and the LM317 low-voltage integrated regulator was employed to de- sign 150V（DC） circuit. This circuit employs two NPN transistors to achieve pressure limiting between LM317 input and output terminals and the current limiting between stabilizing and input terminals,and it has high accuracy.
