Title
(EN) GAS INSULATED HIGH VOLTAGE ELECTRICAL DEVICE EQUIPPED WITH AN ENHANCED PARTICLE TRAP
(FR) DISPOSITIF ÉLECTRIQUE HAUTE TENSION ISOLÉ AU GAZ ÉQUIPÉ D'UN PIÈGE À PARTICULES AMÉLIORÉ
Abstract
(EN)
A gas insulated high voltage electrical device comprising: at least one conductor for conducting a high voltage current; a longitudinal enclosure (30) for enclosing the at least one conductor, the longitudinal enclosure comprising an interior wall (1) extending along a longitudinal axis; a particle trap (9) formed on the interior wall (1) and extending along the longitudinal axis, the particle trap (9) comprising a part of the interior wall (1) and a longitudinal shielding cover (4) extending along the longitudinal axis to delimit a dielectrically shielding area in the enclosure (30) for trapping particles; the shielding cover (4) being made of an electrically conducting material and comprising at least two electrical connections (7) to the interior wall (1) spaced from each other along the longitudinal axis, the shielding cover (4) comprising a mechanical resonating frequency that makes the shielding cover (4) longitudinally oscillate when the high voltage current passes through the conductor.
(FR)
Un dispositif électrique haute tension isolé au gaz comprend : au moins un conducteur pour conduire un courant haute tension ; une enceinte longitudinale (30) pour enfermer le ou les conducteurs, l'enceinte longitudinale comprenant une paroi intérieure (1) s'étendant le long d'un axe longitudinal ; un piège à particules (9) formé sur la paroi intérieure (1) et s'étendant le long de l'axe longitudinal, le piège à particules (9) comprenant une partie de la paroi intérieure (1) et un couvercle de protection longitudinal (4) s'étendant le long de l'axe longitudinal pour délimiter une zone de blindage diélectrique dans l'enceinte (30) pour piéger des particules ; le couvercle de protection (4) étant constitué d'un matériau électroconducteur et comprenant au moins deux connexions électriques (7) à la paroi intérieure (1) espacées l'une de l'autre le long de l'axe longitudinal, le couvercle de protection (4) comprenant une fréquence de résonance mécanique qui amène le couvercle de protection (4) à osciller longitudinalement lorsque le courant haute tension traverse le conducteur.
