Definitions
- busbar systems can be designed as busbar systems.
- the busbars are out in the direction of current flow as elongated, solid conductor. They are used for the transport or distribution of electrical energy.
- Typical tasks of a power rail system are, for example, the connection of a transformer via a main distributor to the sub-distributor and the supply of large consumers.
- the busbars of a busbar system are arranged in a rail box.
- the rail box is used for the mechanical protection and the cohesion of the compo nents of the busbar system. It prevents an un ⁇ desired electrical contact between busbars and the environment can take place.
- the rail box makes sure that the busbars are cooled by natural or forced convection.
- busbars When busbars are used, different materials are used for the rails and housings. As materials for the busbars typically aluminum or copper are used, for the housing typically steel. As these different materials have different thermal expansion coefficients, it is used in the heating or cooling of the current rail system to a Real ⁇ tivdoch between the components. As a result, it is necessary to introduce mechanical expansion elements that compensate for the rela tivverschiebungen. Typically, canted, flexible plate packs are used for this, which in series within the busbars. Disadvantages of such expansion elements are that on the one hand expensive and expensive materials must be used and on the other hand, an additional effort to produce a disk set is necessary. Often, expansion elements mechanically and / or electrically represent the weakest point of an electrical distribution system.
- the busbars ⁇ system for this purpose comprises at least one suspension, which are arranged in series a holder and comprises a flexible bearing, and at least one of the suspension mechanically fixed conductor rail, wherein the flexible bearing a movement of the min ⁇ least a busbar in the direction perpendicular to the sequence of flexible position and support allows.
- the at least one busbar is mechanically fastened by the suspension to egg ⁇ ner wall, so that changes in length of the at least one busbar by the flexible bearing allows who ⁇ the.
- the advantage here is that in the inventive power ⁇ rail system no additional expansion elements must be used.
- the relative displacement in the positive or negative direction of the busbar is made by external, non ⁇ current components, namely the suspension with bracket and flexible bearings.
- the flexible bearing may consist of a resilient element.
- the resilient element may be made of plastic, metal or an organic material.
- the resilient element may be made of elastomer.
- the flexible bearing is arranged on the at least one busbar.
- the holder may be arranged on the at least one busbar.
- the busbar system comprises an additional housing, which encloses the at least one busbar in a touch-proof manner.
- the busbar system may be arranged substantially vertically.
- the Stromschienensys system includes a plurality of suspensions that attach the at least one Stromschie ne mechanically to the wall.
- FIG. 1 busbar system with suspension from holding and flexible bearing and busbar
- FIG. 1 diagram displacement of the flexible bearings for different elements in the tower of a wind ⁇ energy plant.
- a busbar system 100 which includes suspensions 200, 201, 202, 203 and to the suspensions 200, 201, 202, 203 busbar 300 fixed mechanically.
- the suspensions 200, 201, 202, 203 comprise housings 210, 211, 212, 213 and flexible bearings 220, 221, 222, 223 arranged in series.
- the flexible bearings 220, 221, 222, 223 allow the bus bar 300 to move in the direction perpendicular to the sequence of flexible bearings 220, 221, 222, 223 and brackets 210, 211, 212, 213.
- FIG. 1 a busbar system 100 is shown, which includes suspensions 200, 201, 202, 203 and to the suspensions 200, 201, 202, 203 busbar 300 fixed mechanically.
- the suspensions 200, 201, 202, 203 comprise housings 210, 211, 212
- this change in length can be made possible by the flexible bearings 220, 221, 222, 223.
- the bus bar 300 is mechanically fastened to a wall 400 by the suspensions 200, 201, 202, 203.
- the changes in length of the busbar 300 are made possible by the flexible bearings 220, 221, 222, 223.
