作者根据电弧运动这一特定的研究对象,选用了三种高速摄影方法,对横向磁场中的电弧运动过程分别进行了多次拍摄试验。分析比较了此三种方法的优缺点及适用范围。 作者用第三种高速摄影方法观察了熔丝引燃过程、电弧起始停滞现象、弧根在运动过程中的停滞现象、弧柱运动和电弧熄灭过程,发现其中某些特异现象及电弧运动的过程细节,对于进一步探索电弧运动机理有重要意义。
According to the specific research object of arc movement, the authors selected three high-speed photography methods and conducted multiple shooting experiments respectively on the arc movement in transverse magnetic field. Analysis and comparison of the advantages and disadvantages of these three methods and the scope of application. The authors observed the fuse ignition process, the initial stagnation of arc, the stagnation phenomenon of arc root during the movement, the arc column movement and the arc extinguishing process by the third high-speed photography method. Some special phenomena and arc movement were observed The details of the process are of great significance for further exploring the mechanism of arc motion.
