| 摘要 |
The invention concerns a device for preventing the establishment of an electric arc between adjacent portions (9) having no electrical insulation of at least two electrically conductive elements (7). According to the invention, the device comprises at least one separating partition (13) made of dielectric material inserted between said adjacent portions (9) of said conductive elements (7), the dimensions of said separating partition (13) being adapted so that the shortest path between said adjacent portions (9), by bypassing said separating partition (13), corresponds to an instability threshold for an electric arc that is likely to be established between said adjacent portions.
