Abstract

Method and device for connecting power lines to earth and neutral rails (5) iel exchanges. The method provides better space and facilitates the installation of the power lines to the earth and neutral rails (5) in the power stations when these are installed in the properties. This is achieved by placing the earth and zero rails (5) vertically on each side of the power station. This frees up space in the power station, especially for the cables which in most cases are connected to the power station upstream.

Description

It is therefore an object of the present invention to provide a solution to the above problems with a simpler method and device for connecting power lines to earth and neutral rails in power stations. The method provides better space and facilitates the installation of the power lines to the earth and neutral rails in the power stations when these are installed in the properties. This is achieved by placing the earth and zero rails vertically on each side of the power station. This frees up space in the power station, especially for the cables which in most cases are connected to the power station from above.

Description The method provides better space and facilitates the installation of the power lines to the ground and neutral rails in the power stations when these are installed in the properties. The earth and zero rails are placed vertically on opposite sides of the power station. This frees up space in the power station, especially for the cables which in most cases are connected to the power station from above. This solves the problem of the very cramped space when the cables are to be connected and mounted in the power station. The fact that the problem with this has long been known in specialist marble circuits, but nevertheless has not received a satisfactory solution, suggests that inventive step exists.

To achieve this, the device housing is built up with two ends which are bent at the lower edge into a z-profile facing each other, after which the ends are connected to each other with washers and form the bottom plate in the device housing. The components for the power station are then mounted on your rails. The construction of the gables allows the ground and neutral rails that are mounted in rail holders to be snapped into the z-profile. For wall mounting, the ends are fitted with new keyholes and screw sockets in the lower part of the: z-profile. The ends are bent inwards at the top with a fl end equipped with screw holes for a hood, which protects the components included from mechanical damage, and also protects users from dangerous spamming.

The bottom plate in the device housing can also be provided with a back plate which on each side is - connected to ends. When a back plate is used, it is held in place between the ends, by the back plate being provided with fl ikar that fits in at the bottom through the z-pro fi in the ends. An embodiment of the invention is described in the following and illustrated in the accompanying drawing, which according to - Fig. 1 shows a view from below on the base plate of a power station with mounted earth and zero rails.

Fig. 2 shows a view from the front of the base plate to a power station with mounted earth and neutral rails.

Fig. 3 shows a profile on a gable with mounted earth and zero rails.

Fig. 4 shows a perspective view obliquely from the side of a part of a gable and where a back plate is used in a power station with mounted earth and zero rails.

Fig. 5 shows a perspective view obliquely from above on a power station with a hood removed and with cohesive din rails and mounted ground and zero rails, as well as a mounted back plate and an earth fault circuit breaker.

The bottom plate is built up with two ends (2) which in the lower edge are bent into a z-profile (3) which are facing each other, after which the ends (2) are connected to each other with your rails (12). The components for the control panel are mounted on the rail rails (12) 10 15 20 25 30. The construction of the end caps (2) allows the ground and neutral rails (5) mounted in rail holders (4) to be snapped into the z-profile (3). For attachment to a wall, the z-profile (3) at the bottom is provided with a keyhole (6) in the upper part and a screw socket (7) in the lower part. The ends (2) are bent inwards at the top with a (end (9) provided with screw holes (8) for a hood, which protects the constituent components from mechanical damage, and also protects users from dangerous spamming. i Method and device for connecting power lines to earth and neutral rails in power stations according to fi Figure 3 shows a profile on a gable (2) with mounted earth and zero rails (5). The end caps (2) are fitted at the bottom with a z-profile (3) and at the top with a flange (9) provided with screw holes (8). The lower raised plane (10) of the Z-profile (3) is designed so that the rail holder (4) can be snapped. The ground and neutral rails (5) are mounted in the rail holders (4).

Method and device for connecting power lines to earth and neutral rails in power stations according to figure 4 shows a perspective view diagonally from the side of a part of a gable (2) to a power station with mounted ground and zero rails (5 ) mounted in 'rail holders (4). The end caps (2) are provided with keyholes (6) in the upper part and screw sockets (7) in the lower part) of the z-profile (3) and at the top with a fl end (9) provided with screw holes (8). The figure also shows how a back plate (1) connects when one is used. The back plate (1) is provided with fl ikar (11) which are entered at the bottom through the z-profile (3) in the end (2).

Method and device for connecting power lines to earth and neutral rails in power stations according to figure 5 shows a perspective view diagonally from above of a power station with removed hood and ends (2) with bent z-profiles (3) held together of washers rails (12) and a mounted back plate (1) and an earth fault circuit breaker are shown in the fi clock.
