Abstract
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.
Claims7
A multi-electrode rotary system comprising:
- a machine including a revolving contactor,
- at least two electrically conductive elements, each conductive element being provided with an insulting sheath and having a stripped portion at one of its ends, the stripped portion being in electrical contact with the revolving contactor,
- at least one separating partition made of dielectric material and inserted between the stripped portions of two adjacent conductive elements, the at least one separating partition overhanging beyond the corresponding stripped portions of the conductive elements over a height at least equal to about half of the shortest distance that separates the separating partition from each of the stripped portions.
