电磁继电器二次吸合电压的研究与测量

Study and measurement of relay second-time close voltage

首先解释继电器产生二次吸合的原因及二次吸合电压。然后依据电磁理论 ,分析了继电器吸合时励磁电流的动态变化特征 ,应用电子技术和计算机技术 ,设计出了一种电磁继电器二次吸合电压测量系统。

Firstly this paper explains relay's second-time close voltage; According to the theory of electromagnetism, analyses the dynamic process of relay's excitation current when close. Then using electronics and computer technology, designed a measuring system of second-time close voltage.
