Description

[Detailed Description of the Invention] The present invention relates to a simple indoor supply device that improves the workability of arrangement and assembly and has a compact overall configuration.

As a simple indoor power supply device, in order to supply electricity to a housing complex such as an apartment building, an iron pipe was installed in a borrowed room of the house, and a transformer, bus bar, etc. were supported on the iron pipe to form an electricity supply device. There is something.

However, with conventional equipment, transformers and other equipment were placed cluttered within the rented room, and the busbar connected to the power cable was supported by iron pipes without being shielded from the outside, resulting in a reduction in the occupied area. There was a limit to the amount of power available, making it difficult to work with the location of transformers and connecting busbars on-site, and it was not desirable from a maintenance and safety standpoint.

In view of the above, the present invention aims to improve workability such as placement and assembly, make the overall structure more compact, facilitate maintenance, and increase safety. The present invention provides a simple indoor supply device in which a high voltage bus bar is connected between the units in a plug-in manner.

The indoor simple supply device according to the present invention will be explained in detail below.

FIGS. 1A and 1B show an embodiment of the present invention, which has a power supply switching unit 10 and a transformer storage unit 20 respectively arranged in a rented room 1. As shown in FIG. 2A, the power switch unit 10 is configured so that it can be divided into upper and lower units 10a and 10b at a dividing portion 10c to facilitate transportation (examples of configurations that can be divided will be described later). ), molded connection parts 13, 13a, 13b that provide connection between the power supply underground cable 11 and the high voltage insulated bus bar 12
and a disc control operation section 14 that opens and closes this connection. The underground cable 11 and the molded connection parts 13a, 13b can be easily and reliably connected by, for example, terminal-processing the underground cable 11 and inserting it into the molded connection parts 13a, 13b using a plug-in method. It can be carried out. Further, as shown in FIG. 2B, the transformer storage unit 20 is configured so that it can be divided into upper and lower units 20a and 20b at a dividing portion 20c for ease of transportation (a configuration that allows it to be divided is A transformer 21 (an example of which will be described later) is housed therein. The transformer 21 has a high voltage insulated bus bar 12 with a cutout 22 in the middle.
It is designed to be connected to a power source via a power source, and also has a low voltage distribution line 23 for load. FIG. 1A shows that two transformers 21 having different capacities are housed in two units 20, respectively. Figure 2C shows each unit 1 mentioned above.
An example of a divided configuration of 0 and 20 is a transformer storage unit 20.
The connecting piece 20d welded to the upper unit 20a and the lower unit 20b that fits inside the connecting piece 20d are connected to the bolt 20.
A dividing portion 20c of the upper and lower units 20a and 20b is formed by connecting them by e, thereby making it possible to easily divide and integrate them. In addition, each unit 10, 2
0 has upper units 10a and 20a respectively with doors 15 and 24 that can be opened and closed. According to FIG. 2B, the door 2 provided in the transformer storage unit 20
4 is shown, and the opened door 24 is housed in the upper part of the upper unit 20a as shown by the arrow and dotted line. With this structure, when the high-voltage insulated bus 12 is in a live state, the live part can be completely shielded from the outside by opening the door 24, operating the cutout 22, and closing the door 24 after the operation, resulting in excellent operability. and safety.
Furthermore, as shown in FIG. 1A, each unit 10,
20 have a high voltage bus bar connection 12a between them. This connecting portion 12a will be described in detail later.

According to the above configuration, the power switch unit 10 and the transformer storage unit 20 are arranged based on the layout determined according to the size and shape of the rented room 1, and high voltage insulation is provided at the connection part 12a between the units 10 and 20. A simple indoor supply device can be constructed by simply connecting the bus bar 12. In this case, for example, the power switch unit 10 can be arranged as shown in solid lines or dotted lines as shown in FIG.
The layout can be arranged according to the rented room 1.

Figure 3 A, B, and C are the unit 1 mentioned above.
A plug-in connection part for connecting the high voltage insulated bus bar 12 is shown at the connection part 12a between 0 and 20. Bus line 1
2 is an insulator 12a in the units 10 and 20.
The conductor 12b is fixed in a state where the conductor 12b is exposed by stripping the conductor 12b in advance. Insulating cover 3 is attached to this bus bar 12.
0a and 30b, and connect the flexible conductor 3 to the conductor 12b.
an elastic compression sleeve 32a provided at both ends of 1;
Insert and fix one 32a of 32b (FIG. 3A). Then another elastic compression sleeve 32
After inserting and fixing b into the other conductor 12b, move the insulating covers 30a and 30b to form the concave-convex fitting part 30c.
A connecting part is provided by integrating the two parts with each other (FIG. 3 B and C). According to this flexible connection part 12a, even if there is a slight level difference on the floor surface where each unit 10, 20 is arranged, this level difference can be absorbed by the flexible conductor 31, so that it can be easily connected. In addition to providing high workability, a reliable connection can be constructed without making the floor level very accurate.

As explained above, according to the indoor simple supply device according to the present invention, a prefabricated unit housing and fixing a transformer and a high-voltage insulated bus bar is placed in a rented room, and the high-voltage bus bar is connected between the units by a plug-in method. Therefore, workability such as arrangement and assembly can be improved, the overall configuration can be made more compact, maintenance can be made easier, and safety can be improved.
