Although the fuse is one of oldest components of electrical engineering, its operating remains very complex because of the extreme rapidity of the phenomena and the fact that they take place in an opaque environment. Until now, engineers and researchers have only studied the fuse operation by indirect method, simulation or post mortem fuse state. But, a collaboration between mixed research units with the European Synchrotron for Research Facilities allowed filming the fuse operating by x-ray imaging. The method specification is to record the sequence with 5 million frames per second. The conductive material is thus observed to pass from a solid-liquid phase to an initiation of the plasma, thereby establishing the initial conditions of the arcing phase. The high speed films also permit to observe the lengthening of the arc in a few microseconds. The images can be synchronized with the voltage and the current, which makes it possible to return to the calculation of the electric fi...

使用电容器放电下X射线高速成像中电弧延伸的数据

尽管保险丝是电气工程中最古老的组件之一，但由于这种现象的极快性以及它们发生在不透明的环境中的事实，其操作仍然非常复杂。到目前为止，工程师和研究人员仅通过间接方法，模拟或事后验算熔断器状态研究熔断器的工作情况。但是，混合研究部门与欧洲研究机构同步加速器之间的合作允许对通过X射线成像操作的保险丝进行拍摄。方法规范是记录每秒500万帧的序列。因此观察到导电材料从固液相转变为等离子体的起始，从而建立起弧阶段的初始条件。高速胶片还允许在几微秒内观察到电弧的延长。
