Embodiment Construction

[0022] figure 1 A low-voltage power switch 1 is shown in a schematic sectional illustration. The upper connecting busbar 3 shown in conventional form and the lower connecting busbar 4 shown in the embodiment of the invention and passing through the current transformer 6 pass through the rear wall 2 of the low-voltage power switch 1 . There are fixed switch contacts 5 on the upper connection bus bar 3, and on the lower connection bus bar 4, a contact seat 9 that can be moved on a contact seat 9 connected to the switch drive device 8 is connected through a flexible connection part not shown. Switch contacts 10. An arc quenching chamber 7 is arranged on the fixed switching contact 5 and the movable switching contact 10 .

[0023] figure 2 A side view of a possible advantageous embodiment of a lower connecting busbar 4 according to the invention is shown. It consists of a profiled upper part 11 and a profiled lower part 12 . These two parts are positively connected to each o...

Abstract

The invention relates to connecting bars (4) made from profiled semifinished products and having a cavity, said bars having the same outer dimensions for different nominal currents and being intended for connecting the electrical components of electrical devices and apparatus to an external electrical circuit, wherein the connecting bars extend through the window opening located in the wall of the devices or apparatus and are fixed in the housing by fixing means consisting of two or more partial parts (11, 12) embodied as profiles, which are configured in such a way that they can be connected to one another by positive fit or otherwise to a hollow connecting bar (4). The partial parts (11, 12) have one or several legs (13; 16; 17), the length of which defines the height of the connecting bar (4).

Description

technical field [0001] The invention relates to a connecting busbar manufactured from a profiled semi-finished product and having a cavity for connecting electrical components of an electrical installation to an external circuit, wherein the connecting busbar passes through a window in the wall of the electrical installation or installation and through The fixing mechanism is fixed in the housing. Such a connecting busbar has been proposed in German patent application 19939710.4. Background technique [0002] In this way, it is possible, for example, to connect a device-side power supply busbar or another connection piece suitable for power supply or electrical energy output to the part of a connection busbar which leads outwards from the housing. In this case, the connecting busbars are usually fixed firmly in the insulating wall of an electrical installation or electrical equipment, which is usually achieved by means of through-holes and fixing elements. [0003] In addi...
