| 實(shí)驗(yàn)中首先對(duì)各部分投入時(shí)的分散性進(jìn)行了測(cè)試,以便更好的得到電弧圖像,其次對(duì)得到的電弧圖像分階段分別進(jìn)行了分析,采用Matlab圖像處理技術(shù)對(duì)電弧圖像進(jìn)行了二值化,并進(jìn)行了亮點(diǎn)的統(tǒng)計(jì),得到了電弧面積變化曲線,通過(guò)與普通交流的對(duì)比,得出了直流開(kāi)斷的電弧的相關(guān)特點(diǎn),最后對(duì)不同開(kāi)斷速度下的電弧面積變化進(jìn)行了分析,為直流電弧真空中開(kāi)斷的研究提供了一定的參考意義。 |
