Title (EN) VACUUM SWITCHING APPARATUS AND CONTACT ASSEMBLY THEREFOR
(FR) APPAREIL DE COMMUTATION À VIDE ET ENSEMBLE DE CONTACT ASSOCIÉ
Abstract: front page image
(EN)A contact assembly (100, 200, 300, 400, 500, 600) for a vacuum switching apparatus (2) includes a contact member (102, 202, 302, 402, 502, 602) and a reinforcing member (104, 204, 304, 404, 504, 604) adapted to structurally reinforce the contact member (102, 202, 302, 402, 502, 602). The contact member (102, 202, 302, 402, 502, 602) includes first and second opposing sides (106, 306; 108, 308), and a contact thickness (110, 310). The reinforcing member (104, 204, 304, 404, 504, 604) has a reinforcement thickness (112,312), which is less than the contact thickness (110, 310). The contact member (102, 202, 302, 402, 502, 602) is made from a first material having a first coefficient of thermal expansion, and the reinforcing member (104, 204, 304, 404, 504, 604) is made from a second different material having a second coefficient of thermal expansion. The first coefficient of thermal expansion is substantially the same as the second coefficient of thermal expansion.
(FR)L'invention concerne un ensemble de contact (100,200,300,400,500,600) pour un appareil de commutation à vide (2) qui comprend un élément de contact (102,202,302,402,502,602) et un élément de renforcement (104,204,304,404,504,604) conçu pour renforcer structurellement l'élément de contact (102,202,302,402,502,602). L'élément de contact (102,202,302,402,502,602) comporte des premier et deuxième côtés opposés (106,306; 108,308), et une épaisseur de contact (110, 310). L'élément de renforcement (104,204,304,404,504,604) a une épaisseur de renforcement (112, 312) qui est inférieure à l'épaisseur de contact (110, 310). L'élément de contact (102,202,302,402,502,602) est composé d'un premier matériau ayant un premier coefficient d'expansion thermique, et l'élément de renforcement (104,204,304,404,504,604) est composé d'un deuxième matériau différent ayant un deuxième coefficient d'expansion thermique. Le premier coefficient d'expansion thermique est pratiquement le même que le deuxième coefficient d'expansion thermique.
