摘　　要：针对电力系统接地网腐蚀造成重大安全经济损失的问题,并结合传统检测技术的不足,文中研究并设计了一种基于电磁脉冲逆散射成像原理的接地网腐蚀状态检测系统,其主要包括电磁脉冲发射装置、接收装置以及成像系统。借助电磁脉冲发射装置向埋于地下的接地网发射电磁信号,通过信号接收装置收集包涵接地网信息状态的回波信号,并由数据解析及成像系统进行信号解读和图像构建,进而可有效地将接地网的腐蚀断裂等损坏情况以图像的形式显现出来。实验结果验证了,该检测装置的可行性和可靠性,能满足电力系统接地网的腐蚀检测与定点检修等实际工程需求。Aiming at the problem of major safety and economic loss caused by corrosion of power system grounding grid and combining with the shortcomings of traditional detection technology,this paper studies an effective grounding grid corrosion state detection system based on electromagnetic pulse inverse scattering imaging principle,including electromagnetic Pulse transmitting device,receiving device and imaging system. Electromagnetic signal is transmitted to the grounding grid buried in the ground by means of the electromagnetic pulse emitting device,and the echo signal of the state of the grounding network information is collected by the signal receiving device. Signal interpretation and image construction are performed by the data analysis and imaging system,and then the damage such as corrosion cracking of the grounding grid is revealed in the form of an image. The experimental results verify the feasibility and reliability of the detection device,which can meet the actual engineering requirements such as corrosion detection and fixed-point maintenance of the power system grounding grid.
