Title (EN) INSULATION MATERIAL FOR A DC ELECTRICAL COMPONENT
(FR) MATÉRIAU D'ISOLATION POUR COMPOSANT ÉLECTRIQUE À COURANT CONTINU
Abstract:
(EN) An insulation material for a DC electrical component is suggested. The insulation material comprises a thermoset or thermoplastic matrix and a functional filler component. The functional filler component has a non-linear DC conductivity depending on an applied electrical field strength. At least in a temperature range of 0℃ to 120℃, the functional filler component has a bandgap in the range of 2 to 5 eV, optionally in the range of 2 to 4 eV. Furthermore, a method for producing an insulation material, a use of an insulation material for a high voltage DC electrical component, a DC electrical component comprising the insulation material and the use of a DC electrical component comprising the insulation material in a high voltage DC gas insulated device are suggested.
(FR) L'invention concerne un matériau d'isolation pour un composant électrique à courant continu. Le matériau d'isolation comprend une matrice thermodurcissable ou thermoplastique et un constituant de charge fonctionnel. Le constituant de charge fonctionnel présente une conductivité en courant continu non linéaire dépendant de l'intensité du champ électrique appliqué. Au moins dans une plage de température de 0 °C à 120 °C, le constituant de charge fonctionnel possède une largeur de bande interdite dans la plage de 2 à 5 eV, éventuellement dans la plage de 2 à 4 eV. En outre, l'invention concerne un procédé de production d'un matériau d'isolation, l'utilisation d'un matériau d'isolation pour un composant électrique à courant continu à haute tension, un composant électrique à courant continu comprenant le matériau d'isolation et l'utilisation d'un composant électrique à courant continu comprenant le matériau d'isolation dans un dispositif isolé par un gaz à courant continu à haute tension.
