摘　　要：针对以往电弧图像高速采集系统拍摄成本高,处理周期长,可用信息少的缺点,本文在CCD高速成像技术的基础上建立了新型电弧图像高速采集系统并利用该系统成功拍摄到低压交流接触器开关电弧在燃弧过程中的一系列图像.利用该新型电弧图像高速采集系统对CJX1-12/22型号的交流接触器进行了电弧形态转变与运动特性的研究.通过对所得电弧图像信息的分析处理得到低压交流接触器电弧在不同时刻的弧柱直径及电弧运动速度的数值并归纳出低压交流接触器电弧在燃弧过程中的运动特性,为研究和提高低压开关电器的可靠性和分断能力提供了理论依据.Aiming at the shortcomings of the former arc high-speed image gathering system like high photography cost,long processing period and few available information,we based on the CCD high speed image formation technology to develop a new type of arc high-speed image gathering system and by using this system,we successfully get a series of switching arc images from the burning arc to extinguished arc.This paper uses the new system to proceed the research of arc＇s shape transformation and motion characteristic on CJX1-12/22 AC contactor.Through analyzing the arc image in-formation,we can get the values of the arc column diameter and arc velocity at different time and conclude the motion charcteristic of low-voltage AC contactor arc during arcing process.Doing this will provide theoretical basis for researching and increasing the reliability and breaking capacity of low-voltage switching appatatus.
