摘要
电磁继电器在现代国防军事、工业自动化以及交通运输等领域应用广泛,当系统中的电磁继电器发生失效时将影响整个电气系统的可靠运行。为了提高电气系统的可靠性,需要检测继电器的特性参数,以评估其工作性能并提高其稳定性。针对电磁继电器触点易失效问题,设计了一套基于FPGA的电磁继电器在线测试系统。采用铁路继电器作为试品,分析继电器的各项特性参数,并选取能反映其触点退化程度的时间参数进行测试。这种能够应用于多型号继电器的便携式在线测试系统,可实时检测继电器吸合和释放过程中的电压变化波形并进行数据存储,为后续继电器的性能状态评估提供了数据支撑,也为电磁继电器的维修维护提供了参考数据。
Electromagnetic relays are widely used in the fields of modern national defense,military,industrial automation and transportation.When the electromagnetic relays fail in the system,the reliable operation of the entire electrical system will be affected.In order to improve the reliability of the electrical system,it is necessary to test the characteristic parameters of the relay to evaluate its working performance and improve its stability.Aiming at the problem of easy failure of electromagnetic relay contact,this paper designs a set of online testing system of electromagnetic relay based on FPGA.The railway relay is used as a sample,the characteristic parameters of the relay are analyzed,and the time parameters which can reflect the degree of contact degradation are selected for testing.This portable online test system,which can be applied to multiple relay models,can detect the waveforms of voltage changes during relay suction and release in real time and store the data.It provides data support for the subsequent performance status evaluation of relays,and also provides reference data for the repair and maintenance of electromagnetic relays.
