Problems solved by technology

[0004] Known three-phase busbar systems with rigid contacts cannot be used for switching devices with squirrel-cage spring connection technology, since the squirrel-cage spring connection cannot be opened due to functional limitations
Simultaneous opening of the squirrel-cage springs of several switching devices is very labor-intensive and practically only possible at unreasonable expense, so there is practically no available connection of switching devices with squirrel-cage spring connection technology. suitable solution
At present, these switchgears must be supplied by the main busbar system by means of separate conductors in the switchgear, which requires corresponding labor in assembly

Embodiment Construction

[0023] exist figure 1 shows a switching assembly consisting of a plurality of adjacently arranged switching devices 1 of the same design and dimensions, an associated busbar system 2 that is not yet connected, and a fastening clip 3 for fastening the busbar system. The busbar system 2 is equipped with elastic conductors as connection contacts. In order to connect with the switchgear 1, first hook the fixing clip 3 into the opening 5 of the switchgear 1, then snap the busbar system into the fixing clip 3, and finally pass the elastic wire 4 through the wiring hole 6 of the switchgear 1 and the terminal connect. In this case, the connection terminal can be formed as a screw terminal or be designed according to the squirrel-cage spring connection technique. and figure 1 Unlike what is shown, the elastic conductors 4 can also interconnect switching devices 1 of different designs and sizes and with different switching device spacings.

Abstract

According to the invention several switchgear units (1) positioned next to each other are connected to a busbar system which presents an insulating encapsulation and is situated near the switchgear units. The conductor bars (9) of said system are electrically connected to the terminals of the switchgear units (1) by means of flexible lines (4). The solution provided for in the invention permits the simple connection of switchgear units (1) fitted with cage-clamp connections.

Description

technical field [0001] The invention relates to a switchgear assembly consisting of a plurality of adjacently arranged switchgears, connected to these switchgears by a closed and insulated bus system for supplying power to the switchgears, the busbar system having a plurality of contact rails, each contact rail In each case there are connecting contacts distributed over the entire length of the busbar, which are electrically connected to the terminals of the switching device, wherein the busbar is arranged in a closed insulating housing. Background technique [0002] FIG. 8 shows such switchgear assemblies with closed insulating busbar systems, which have long been offered by switchgear manufacturers. Among them, in order to realize the three-phase connection, the busbar system consists of three contact rails with uniform structure and rigid connection contacts, which are arranged in an insulating housing. Adjacent switching devices have screw terminals which must be discon...
