nach der Bestellung gedruckt Neuware - Printed after ordering - Dans les systèmes d'alimentation électrique à haute tension (HT), divers matériaux (solides, liquides et gazeux) sont utilisés pour l'isolation afin de protéger les équipements électriques à haute tension contre les défaillances précoces. La plupart des matériaux isolants ne sont pas parfaits à tous égards et contiennent certaines impuretés. La présence de bulles d'air est l'une de ces impuretés dans les matériaux isolants, ce qui est hautement indésirable. L'isolation de l'équipement électrique HT se dégrade progressivement en raison de l'effet cumulatif des contraintes électriques, chimiques et thermiques et du vieillissement. En raison de la contrainte de la haute tension, la zone faible à l'intérieur de l'isolant provoque une décharge partielle (DP), ce qui détériore l'isolant. Dans cet article, un modèle de circuit électrique de l'isolateur solide avec des vides est utilisé pour étudier l'activité de la DP menant à la rupture à l'intérieur de l'isolateur. Parmi les modèles (à savoir le modèle capacitif et le modèle de concept de charge induite), le modèle capacitif est adopté dans le présent travail. Le modèle capacitif Simulink mis en oeuvre, démontre efficacement le processus de décharge partielle. Le modèle est utilisé pour étudier et démontrer l'effet de la permittivité de la cavité/impureté et le niveau de tension de début de rupture de l'impureté.…
