摘　　要：直流系统绝缘的状况直接影响变电站继电保护和自动装置的安全运行,一旦发生直流系统的异常接地,供电系统将面临极大的危险。为了在复杂现场条件下迅速准确找出接地点,应用单片机技术和电子技术实现了直流接地探测系统手持探测器的开发设计。实际应用表明,由于采用了独创的探测方法,该设备与传统探测技术相比无探测死区,使用方便简单,能对各种接地情况进行有效探测。DC system insulation condition direct influences the substation protection and automatic device safe operation, once will have the DC system exceptional earth,the power supply system faces great danger. In order to quickly and accurately discovers locations of earth under the complex field condition. Application SCM technology and electronic technology to achieve DC exceptional earth detection system of portable detector design. Practical applications show that the introduction of innovative methods of detection,compares with the traditional technology without the section of dead,the easy to operate is simple, can availably detected various earthed and obtains user higher appraisal.
