Embodiment Construction

[0042] according to figure 1 , the suspension busbar 1 is fastened particularly stably, so that good power transmission is possible without sparks forming at the same time. For this purpose, the suspension contact rail 1 has a cross member 2 which has conically narrowed shaped sections 3 which can be inserted into corresponding grooves 4 of clamping fittings 5 ​​. The clamping fitting 5 is fastened to the fastening device 6 with screws 7 . This achieves a particularly stable fixation of the suspension rail 1 . Protruding from the cross member 2 are two clamping arms 8 for securing conductors 9 . An electrical connector 10 is fixed inside the suspension contact rail 1 for connecting the suspension contact rail 1 and the chain device.

[0043] figure 2 It shows how the suspension conductor rail 1 connects the pivot pin 12 and the adjusting device 13 via the support arm 11 to the building 14 , for example to a tunnel wall, or to a supporting structure. By means of the adjus...

Abstract

The invention relates to an overhead line system comprising overhead conductor rails (1, 16), which are fixed in the center region thereof by a fixed point to a structure (14) and are otherwise connected to the structure (14) by way of moveable support point legs (11). According to the invention, at least one of the overhead conductor rails (1, 16) comprises a transverse carrier (2) at the upper side thereof, two downwardly directed tensioning arms (8) originating from said transverse carrier at connecting points for holding a contact wire (9). The transverse carrier (2) comprises conically tapered moldings (3) on both sides of the connecting points of the tensioning arms (8), which moldings can be inserted in corresponding recesses (4) of a clamping fitting (5).

Description

technical field [0001] The invention relates to a trolley line arrangement comprising suspension conductor rails which are each fixed in their central region to a building by means of a fixed point or otherwise connected to the building by means of movable support arms. Background technique [0002] The movement of the support arm may be a slide. [0003] A building can be a supporting structure. [0004] Such a suspended contact rail is known from Urs Beat Wili in Elektrische Bahnen eb 87 (1989) 10, pages 310 to 315, "Stromschienenoberleitung für Geschwindigkeiten bis 160 km / h". A building is, for example, a tunnel roof. [0005] When driving through tunnels or other buildings with suspended contact rails, disturbances often occur in the transmission of power from the trolley installation to the vehicle's pantograph and thereby to the vehicle's drive motor. These disturbances can also lead to sparks and arcs, which can interfere with radio communications, for example. ...
