摘　　要：通过故障监测终端的测量精度和线路故障诊断分析的研究,表明了故障诊断系统可快速定位故障点,但同时发现了多起定位精度不满足要求的情况,本文以一回多段架空与电缆混合线路跳闸事件作为典型案例进行分析,得出了影响定位精度的主要因素,并提出了相应改进措施。The accuracy of measurement and fault monitoring terminal line fault diagnosis analysis research,suggests that the fault diagnosis system can quickly locate the fault point,but also found that the number of location accuracy does not meet the requirements of the situation,based on the time period of mixed with the cable line trip more events as a typical case analysis,it is concluded that the main factors that affect the location accuracy and puts forward the corresponding improvement measures.
