用于接地电阻测量仪多路电源的设计

Design of multi-powersupply used in grounded resistance surveyor

介绍一种用于新型接地电阻测量仪的电源电路.该电源利用集成芯片技术设计，能满足测量仪工作时所需提供的电源电压、解调电压和稳定的电流源，具有抗干扰能力强、对电池充电快速和电池自检等功能．

In this paper, the authors introduced a kind of power circuits that areused in the new grounded resistance surveyor. By applying the integrated chipstechnology,the power can supply the power-voltage,demodulated-voltage and sta-ble voltatic source that the surveyor needs. The powersupply was provided withsome function of anti jamming,charging quickly,auto-checking.
