摘　　要：本文以应用改进的直流电桥法为基础,以89C52单片机作为主控芯片,配上其他外围设备构成直流系统绝缘电阻在线巡回检测装置,对直流系统进行接地检测。该装置通过对母线的接地检查和支路的接地检查,测得数据,经过处理,自动地显示接地故障支路,从而实现了直流系统绝缘接地巡检装置的自动化和智能化。该装置简单、实用、可靠。A online DC system insulation resistor measuring device controlled by 89C52 with peripheral devices, which is based on the improved DC bridge method, is introduced in this paper. With such simple, practical and reliable device, the automation and intelligence of DC system insulation measuring device could be realized successfully.
