摘要

长期的振动往往会引起电磁继电器的性能降低，甚至失效。针对电磁继电器的工作环境特点，提出了一种电磁继电器振动试验方案，设计了试验电路并进行了试验。试验结果表明：振动频率为40~130 Hz和振动加速度增大时，电磁继电器的释放时间与回跳时间无明显变化、吸合电压减小、释放电压和接触电阻缓慢增加、吸合时间的增幅及其波动量最为明显；在固有频率160 Hz下，性能参数均出现了明显的变化和剧烈的波动，最大波动量约为其他振动条件下的2倍；与振动频率相比，振动加速度对性能参数的影响更大些。通过数据分析发现，振动引发的电磁继电器性能参数变化中，吸合时间是较为敏感的参数。

Abstract

Long-term vibrations often cause performance degradation or even failure of electromagnetic relays. In view of the working environment characteristics of electromagnetic relays, a vibration test scheme for electromagnetic relay was proposed. The test circuit was designed and tested. The test results showed that, when the vibration frequency is 40-130 Hz, and when the vibration acceleration increases, the release time and the bouncing time do not change signi fi cantly, the pull-in voltage decreases, the release voltage and contact resistance increase slowly, and the increase of the pick-up time and the fluctuation is the most obvious; Under the natural frequency 160 Hz, the performance parameters are obviously changed with the violent fluctuations, and the maximum fluctuation is about 2 times of other vibration conditions; Compared with the vibration frequency, the vibration acceleration has greater effect on the performance parameters. It was found that in the change of performance parameters of electromagnetic relay caused by vibration, the suction time is a more sensitive parameter.
