摘　　要：作为继电保护的基础元件,高校继电保护教学实验普遍开设电流和电压继电器特性实验课程。实验过程中发现在调节电磁式继电器启动值和返回值时,电流继电器比电压继电器有更高稳定性,而且电压继电器更容易受使用年限的影响。收集当前本科实验室的两种电磁式继电器实测数据,通过统计方法归纳两种电磁式继电器实际特性情况。进一步结合两种电磁式继电器的原理,从理论上分析上述现象的原因,从而有助于帮助学生更深入掌握继电器特性。As the basic component of relay protection, the experimental course of current and voltage relay is widely used in the teaching of relay protection in universities. During the experiment, it is found that the current relay is more stable than the voltage relay in regulating the starting value and return value of the electromagnetic relay, and the voltage relay is more susceptible to the influence of service life. This paper collects the measured data of two kinds of electromagnetic relays in the current undergraduate laboratory, and sums up the actual characteristics of the two electromagnetic relays by statistical methods. The principle of the two electromagnetic relays is further analyzed, and the reasons for the above phenomena are theoretically analyzed, so as to help the students to master the relay characteristics more deeply.
