CA 2743679

The invention relates to a device (50; 60) comprising rigid connecting bars (51; 61) for conductively connecting first (30; 130; 230) to second (133; 233; 334) busbars, the contact sides (70; 170; 270, 173; 273; 374) of which run parallel to each other and which can be held together with the connecting bars (51; 61) by applying pressure with the help of a first and a second connecting mechanism (80, 80), each of which has a connecting bolt (81) extending transverse to the contact sides. Each of the connecting bars (51; 61) has a first contact surface (56; 66) to conductively contact the contact side (70; 170; 270) of one of the first busbars (30; 130; 230) while having a second contact surface (57; 67) to conductively contact the contact side (173; 273; 374) of one of the second busbars (133; 233; 334). In order to be able to even more easily connect the first and second busbars, especially when said busbars are pre-assembled in segments, e.g. in power module segments of a wind power plant, the connecting bars (51; 61) have a first (53; 63) and a second (54; 64) recess that is open on one side, namely on the side facing the connecting bolts (81), such that the connecting bars embrace the connecting bolts (81).

L'invention concerne un dispositif (50; 60) comportant des barres de connexion fixes (51; 61) pour la connexion conductrice de premières barres conductrices (30; 130; 230) avec de deuxièmes barres conductrices (133; 233; 334) dont les côtés de contact (70; 170; 270, 173; 273; 374) sont parallèles, les barres conductrices pouvant être maintenues les unes contre les autres sous pression au moyen d'un premier et d'un deuxième dispositif de connexion (80, 80) présentant respectivement un boulon de connexion (81) perpendiculaire aux côtés de contact. Chaque barre de connexion (51; 61) comporte une première surface de contact (56; 66) pour la mise en contact conductrice du côté de contact (70; 170; 270) d'une des premières barres conductrices (30; 130; 230), et une deuxième surface de contact (57; 67) pour la mise en contact conductrice du côté de contact (173; 273; 374) d'une des deuxièmes barres conductrices (133; 233; 334). Pour simplifier davantage la connexion des premières et deuxièmes barres conductrices, notamment lorsque celles-ci sont prémontées en segments, par exemple dans des segments de modules de puissance d'une éolienne, les barres de connexion (51; 61) présentent un premier évidement (53; 63) et un deuxième évidement (54; 64) ouverts unilatéralement, respectivement sur le côté orienté vers les boulons de connexion (81), pour recouvrir les boulons de connexion (81).
