In a thesisbachelor work foreign ultra-fast DC disconnectors are considered. Contact system composition of the ultra-fast DC disconnector 180 kV, 2500 A is suggested. Mechanical calculations associated with some aspectsof the contact system work are made. Contact resistance of the disconnector and heating temperature of the contact system during the rated current and striking short circuit current flow are determined.
