Description

[Detailed explanation of the idea]

The present invention relates to a branching device for storing cubicles in a π interconnection distribution line. Figure 1 shows the connection of the π interconnection distribution line. In the figure, 1 and 2 are switches for supply lines, and 3 is a switch for consumers. Further, 4 and 5 are fuses, both of which distribute power to consumers via a cable head 6. The cable head 7 is also connected to switches 1 and 2 for supply lines. FIG. 2 shows a conventional example of the arrangement of these devices. Here, the same reference numerals are given to the equipment corresponding to the equipment shown by the wiring in FIG. 1. In this arrangement example, each switch and each fuse are
Because each circuit is placed in an independent box, arranged horizontally in a row, and cables are drawn in from the bottom, a rising busbar 8 is required to connect the consumer switch and the fuses 4 and 5, and each box The height of the box had to be increased because of the conductor 9 that communicates with the box. This idea was created with these points in mind.
This embodiment will be explained with reference to FIG. Note that the same reference numerals are used for the same components as in the conventional example. Switches 1 and 2 for supply lines and switch 3 for consumers
are arranged in a T-shape, and the inner poles are connected in a Y-shape, and cable heads 10 with hidden live parts are installed at both ends of the horizontally arranged supply line switches 1 and 2. The lower part of the main circuit switch 3 which is connected and arranged vertically is connected to the lower part of fuses 4 and 5 which are vertically provided on both sides of the switch 3, respectively. Also, the upper part of fuses 4 and 5

[Table] Unit: mm
As a result, the occupied area has been reduced by 63% and the volume by 58% compared to the conventional example. As explained above, according to this invention, the installation area can be reduced to about 60%, and by changing the cable extraction part, the cable pit depth can be reduced from about 600 mm.
It was possible to shorten it to 300mm.

[Brief explanation of the drawing]

FIG. 1 is a single line diagram, FIG. 2 is a single line diagram showing the arrangement of a conventional device, and FIG. 3 is a single line diagram showing an embodiment of the present invention. In the figure, 1, 2 and 3 are switches, 4 and 5 are fuses, 10 and 11 are cable heads, 12 is a bulkhead, and 13 is a box.

Claims (1)

[Scope of utility model registration request] Three switches are arranged in a T-shape, with the inner poles connected in a Y-shape, and cable heads with live parts hidden are connected to both ends of the horizontally arranged switches, which are arranged vertically. The lower part of each switch connected to the switch is connected to the lower part of the fuse provided vertically on both sides of the switch, and the upper part of the fuse is equipped with a cable head that hides the live parts, and a partition is installed between each switch and the fuse. What is claimed is: 1. A branching device characterized in that each of the above devices is housed in a common box, and the cable head is drawn out of the box.
