Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power distribution transformer installed on a utility pole, and more particularly to a utility pole integrated type transformer in which the occupied space in the installed state is reduced.

[0002]

2. Description of the Related Art As is well known, as a method of mounting a distribution transformer on a wooden or concrete power pole,
BACKGROUND ART Conventionally, most of them are a pedestal mounting pole for fixing a transformer to a armband mounted on a telephone pole, and a hangar pole means for hanging and fixing a transformer on a telephone pole.

However, in the conventional pole mounting means for such a transformer, the space occupied by the transformer on the electric pole is large, and the transformer is installed in a substantially bare state, so that the surrounding environment is low. Not only is it inconvenient to lose the degree of freedom with regard to the installation position of the utility pole, because it is necessary to separate the transformer from the building for a certain distance as a safety measure, as well as impairing the beautification of the environment and spoiling the environment beautification There is a problem that it also hinders fire-fighting activities during high-altitude fires.

[0004]

SUMMARY OF THE INVENTION As described above, the conventional pole means of the distribution transformer has various problems such as environmental beautification, safety measures, and fire fighting activities. ing. Therefore, the present invention has been made in consideration of the above circumstances, and is an extremely good utility pole-integrated transformer that is aesthetically harmonized with the surrounding environment, enhances safety for buildings, and does not hinder fire-fighting activities. The purpose is to provide a container.

[0005]

A utility pole-integrated transformer according to the present invention is constructed such that an accommodating member accommodating a distribution transformer is attached to the tip of the utility pole. The transformer is formed in a columnar shape having a peripheral surface shape substantially the same as the peripheral surface of the electric pole, and the housing member is formed in a substantially cylindrical shape that covers the peripheral surface of the distribution transformer.

[0006]

With the above-described structure, the space occupied by the distribution transformer on the utility pole can be reduced, and the distribution transformer is installed in a state of being covered by the housing member. It is easy to achieve aesthetic harmony with the environment and does not impair the beautification of the environment.As a safety measure, the distance between the distribution transformer and the building can be short, so there is no loss of freedom regarding the installation position of the utility pole. , Fire fighting activities at high altitude fire will not be disturbed.

A second tubular portion 21 having a low-voltage connecting portion 20, 20, 20 for transmitting electric power from the distribution transformer 14 to the three low-voltage distribution lines 19, 19, 19 is formed below the component 5. Has been done.

As shown in FIG. 2B, the distribution transformer 14 has a columnar shape having a peripheral surface shape substantially the same as the peripheral surface shape of the electric pole 11. On the upper surface of the distribution transformer 14 in the drawing, the connection line 2 routed inside the first tubular portion 18 is provided.
Via high-voltage connecting parts 17, 17, 1 via 2, 22, 22
7 is connected to the low-voltage connecting portions 19, 19 and 19 via the input terminals 23, 23 and 23 connected to 7 and the connecting wires 24, 24 and 24 routed inside the second tubular portion 21. Output terminals 25, 25, 25 are arranged.

The tubular support portion 15 is a distribution transformer 14
It has a substantially cylindrical shape that covers the peripheral surface of the. At the connecting portion between the tubular support portion 15 and the second tubular portion 21, a flange in which the peripheral surface of the tubular support portion 15 spreads outward with a step outside the peripheral surface of the second tubular portion 21. The part 26 is formed, and this collar part 2 is formed.
The distribution transformer 14 is placed inside the device 6. Further, on the inner peripheral surface of the tubular support portion 15, three substantially ring-shaped support portions 27, 27, 27 for supporting the distribution transformer 14 in contact with the peripheral surface thereof are provided substantially vertically in the drawing. It is formed at equal intervals.

According to the configuration of the above-described embodiment, the distribution transformer 14 having a columnar shape having a peripheral surface shape substantially the same as the peripheral surface shape of the electric pole 11 is formed into a substantially cylindrical shape covering the peripheral surface. Since the housing member 12 is configured to be housed in the housing member 12 having the tubular support portion 15, and the housing member 12 is attached to the tip of the utility pole 11, the distribution transformer 14 on the utility pole 11 is arranged.
The occupying space can be reduced and the distribution transformer 14 is installed in a state of being covered by the housing member 12, so that it becomes easy to aesthetically harmonize with the surrounding environment and impair the beautification of the environment. In addition, since the distance between the distribution transformer 14 and the building can be shortened, the degree of freedom regarding the installation position of the utility pole 11 is not lost and, in addition, in the event of a fire in a high place. It will be less likely to interfere with fire fighting activities in.

FIG. 3 shows an example in which the utility pole described in this embodiment is installed on a street. Compared with a conventional distribution transformer mounted on a utility pole, the space occupied on the utility pole 11 is small, and since the distribution transformer 14 is covered by the housing member 12, the overall structure is neat. It can be seen that it becomes a beautiful landscape and it is easy to achieve aesthetic harmony with the surrounding environment. Further, it can be seen that the distance between the utility pole 11 and the building is short, which is very advantageous in terms of safety measures and is less likely to interfere with fire fighting activities during a fire in high places.
