摘 要： 針對(duì)大容量中壓直流斷路器故障電流開斷過程，利用CCD 高速攝影裝置對(duì)電弧運(yùn)動(dòng)過程進(jìn)行了影像捕捉。該實(shí)驗(yàn)是在1 400 V 直流開斷實(shí)驗(yàn)平臺(tái)上完成，分別在矩形和V 型兩種不同滅弧室結(jié)構(gòu)下進(jìn)行直流斷路器開斷實(shí)驗(yàn)，并對(duì)比兩者的開斷特性。結(jié)果發(fā)現(xiàn)滅弧室結(jié)構(gòu)對(duì)滅弧性能有重要影響，矩形滅弧室與V 型滅弧室對(duì)燃弧過程的影響差別很大。通過檢測(cè)電弧影像的實(shí)驗(yàn)研究對(duì)大容量中壓直流斷路器的設(shè)計(jì)具有重要的指導(dǎo)意義。

Abstract: In allusion to the fault current breaking process of high-capacity medium-voltage DC circuit breaker, images of arc motion were captured by CCD high-speed cinetoscope. The experiment was completed on 1 400 V DC breaking platform.    Experiments were carried out on DC circuit breaker with rectangular interrupter and ‘V’ interrupter, and the breaking performances were compared. The results show that the structure of interrupter has an important influence on quenching performance. The rectangular interrupter and ‘V’interrupter were different in arcing process. The research on arc-image capture has important directive significance in design of highcapacity medium-voltage DC circuit breaker.
Key words: medium-voltage DC circuit breaker; high-speed cinetoscope; high-capacity making and breaking; arc shape; experimental research
