摘 要：近年来，伴随着我国社会经济的高速发展，社会用电需求也逐年增长，我国也在不断加快电力系统建设来满足用电需求。电气二次回路是电力系统重要的功能性部件，对于电网的稳定、高效运行具有重要意义，但是二次回路也是电力系统中故障率较高的设备，如何及时发现并处理电气二次回路故障、采取合理防范措施降低故障率，已经成为近年来电网建设中亟待解决的难题。本次研究正是在这样的背景下展开的，首先对电力系统电气二次回路进行了简单介绍，从电源性质、用途等方面对二次回路进行了分类；然后分别分析了电压互感器、电流互感器以及继电保护系统的二次回路故障；最后，从遵照工作规范、提升专业技能、把控修改流程三个方面提出了电气二次回路故障的防范策略，以降低二次回路的故障率，推动电力系统的安全、稳定、高效运行。

Abstract：In recent years，with the rapid development of China’s social economy，the social demand for electricity is also increasing year by year. China is also accelerating the construction of power system to meet the demand for electricity. Electrical secondary circuit is an important functional component of the power system，which is of great significance for the stable and efficient operation of the power grid. However，it is also a high failure rate equipment in the power system. How to detect and deal with electrical secondary circuit faults in time and take reasonable preventive measures to reduce the failure rate has become an urgent problem to be solved in the construction of the power grid in recent years. This research is carried out under this background. Firstly，the electrical secondary circuit of power system is briefly introduced，and the secondary circuit is classified from the nature and use of power supply. Secondly，the secondary circuit faults of voltage transformer，current transformer and relay protection system are analyzed separately. Finally，the secondary circuit faults are modified according to the working standards，professional skills and control. In the three aspects of the process，the prevention strategies of electrical secondary circuit fault are put forward to reduce the failure rate of secondary circuit and promote the safe，stable and efficient operation of power system.
