Abstract[English]
The invention relates to the field of switching devices and provides a method for manufacturing liquid-metal composite contacts with elastic, flexible frameworks made of refractory metal. The invention addresses issues related to the reliability and longevity of contacts in switching devices and simplifies their manufacturing process, allowing for mass production using existing equipment and skilled specialists. The resulting liquid-metal contacts possess high elasticity, improved contact properties, and resistance to welding, enhancing the switching capacity of OLTC and other switching devices. The invention has significant commercial potential and can be applied in various industries that require highly reliable and efficient switching devices.[French]
L'invention concerne le domaine des dispositifs de commutation et propose un procédé de fabrication de contacts composites liquide-métal avec des structures souples élastiques constituées de métal réfractaire. L'invention aborde les problèmes liés à la fiabilité et à la longévité de contacts dans des dispositifs de commutation et simplifie leur processus de fabrication, ce qui permet une production de masse à l'aide d'équipements existants et de spécialistes compétents. Les contacts liquides-métalliques résultants possèdent une élasticité élevée, des propriétés de contact améliorées et une résistance au soudage, améliorant la capacité de commutation d'OLTC et d'autres dispositifs de commutation. L'invention présente un potentiel commercial significatif et peut être appliquée dans diverses industries qui nécessitent des dispositifs de commutation hautement fiables et efficaces.
