DEVICE COMPRISING RIGID CONNECTING BARS FOR THE CONDUCTING CONNECTION OF FIRST TO SECOND BUSBARS

摘要

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).
