Abstract
Изобретение относитс к электроаппаратостроению, в частности к контактным узлам коммутационных аппаратов, и может быть использовано при создании сильноточной коммутационной аппаратуры с жидкометаллическими контактами. Целью изобретени вл етс увеличение срока службы контактной пары. При отключении в межконтактном промежутке возникает электрическа дуга, котора испар ет жидкий металл с поверхности контактирующих элементов 3 и 4. Испар ющийс жидкий металл конденсируетс на стенках экранов 5 и 6 и по капилл рной структуре последних транспортируетс к контактным элементам 3 и 4. 2 ил.The invention relates to electrical equipment, in particular to the contact nodes of switching devices, and can be used to create high-current switching equipment with liquid metal contacts. The aim of the invention is to increase the service life of the contact pair. When disconnected, an electric arc arises in the contact gap, which evaporates liquid metal from the surface of contacting elements 3 and 4. The evaporated liquid metal condenses on the walls of shields 5 and 6 and is transported through the capillary structure of the latter to contact elements 3 and 4. 2 Il.
