Abstract

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).

Description

technical field

[0001] The invention relates to the field of wiring and to the construction of a device with rigid connecting rails for the electrically conductive connection of first and second conductor rails, the contact sides of which extend parallel to each other, and which have respective transverse contact sides The first and second connecting means of the extended connecting bolts are fixed together with the connecting rails under pressure, wherein each connecting rail has a first contact surface for electrically conductive contact with the contact side of one of the first conductive rails and for electrically conductive The ground-contacting side of one of the second conductor tracks has a second contact surface. Background technique

[0002] This device is known from document DE 42 02 783 A1, wherein a connecting rail is inserted between first and second conductor rails to be connected with opposite end faces, and then is electrically connected to the first and sec...

Embodiment Construction

[0026] exist figure 1 The wind energy installation 1 shown schematically in the center comprises a tower 2 with a foundation 3 , a nacelle 4 mounted rotatably at the top of the tower, and a power module 5 arranged at the base of the tower.

[0027] Arranged within the nacelle 4 is a rotor with rotor blades 6 mounted rotatably about a horizontal axis, as well as a generator 7 . The rotor is set into rotation by the wind force acting on the rotor blades 6 and drives a generator 7 for generating electrical energy.

[0028] In order to transfer the electrical energy generated by the generator 7 to the power module 5 (which has different electrical units), in the inner space 8 of the tower 2 on the walls there are conductor rails 10 arranged with fixing elements 9, which are adjacent The joints of the tower sections are connected with flexible connecting rails. These conductor rails are electrically conductive and are electrically connected via cables 11 to the generator and via ...
