Description
Известен материал дл электрических контактов на основе вольфрама, содержащий до 7 вес. % вкел .Known material for electrical contacts based on tungsten, containing up to 7 wt. % Enquered
Предложенный материал отличаетс от изfiecTHoro тем, что в его состав фоме вольфрама И никел входит 0,5-10,0% титана. Это обеспечивает активное удаление газов из межэлекпродного пространства вакуу)Мных дугогасительных камер при горении на электродах дугового разр да, в которые благодар эррозии поступает титан. Высока сорбционна способность титаиа .приводит к интеноизному поглощению газов, выдел ющихс и;5 контактов, что способствует успешному гашению дуги. Пары титана конденсируютс затем на стеНКах металлического экрана дугогасительной камеры.The proposed material differs from that by the fact that in its composition the tungsten AND nickel form 0.5-10.0% of titanium. This ensures the active removal of gases from the inter-electrode space of the vacuum chambers during arcing on the electrodes of the discharge, into which, thanks to erosion, titanium enters. The high sorption capacity of titia leads to an intensified absorption of gases evolving and; 5 contacts, which contributes to the successful extinguishing of the arc. The titanium vapors are then condensed on the stacks of the metal screen of the interrupter chamber.
