摘要掌握不同特性电压暂降对交流接触器正常工作性能的影响是相关用户非常关心的问题。制定了试验研究方案,以Chroma 61860回收式电网模拟电源为暂降发生源,选取4个主流厂家、相同型号的交流接触器进行了试验研究,分别考察了电压暂降特征量以及典型电压暂降事件对交流接触器敏感度的影响。通过对大量试验结果的分析,给出了各考察因素对交流接触器敏感性的影响程度,并在试验研究的基础上提取得到了交流接触器电压暂降的敏感度曲线,可为交流接触器对电压暂降免疫能力的分析提供依据。

Abstract：AC contactors are wildly used in industrial process and are sensitive to voltage sags.It is a matter of great concern to the relevant users to master the behavior of AC contactors during different voltage sags.To address this issue,an experimental research program is developed in this paper.Chroma Model 61860 is used as the voltage sag generator.Eight AC contactors that have the same parameters from four widely used brands are selected as the representatives.The effects of the voltage sag characteristics and the typical voltage sag events on AC contactors are researched through extensive experiments.Through analysis of a large number of experimental results,the influence of all the above factors to AC contactor sensitivity is given,and the sensitivity curve which can provide the basis of analyzing AC contactors’ tolerance to voltage sag is extracted.This research can provide evidences for the analysis of the immune ability of AC contactors over voltage sag.
