Description
【考案の詳細な説明】 「産業上の利用分野」 本考案は、柱上設置形地中配電用油入変圧器の構造に関
するものである。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to the structure of a pole-mounted underground power distribution oil-filled transformer.
「従来の技術」 従来の地中配電用油入変圧器のケーブル接続状態の一例
を第２図に示す。第２図において、地中から立ち上がっ
てきたケーブル４は、ベース３の中を通り、ベース３の
上に設置されている地中配電用油入変圧器１の側面の上
部に装着されているブッシング２に接続されている。"Prior Art" Fig. 2 shows an example of a cable connection state of a conventional oil-immersed transformer for underground power distribution. In FIG. 2, the cable 4 rising from the ground passes through the base 3, and the bushing attached to the upper part of the side surface of the oil distribution transformer 1 for underground power distribution installed on the base 3. Connected to 2.
「考案が解決しようとする課題」 しかし、従来の地中配電用油入変圧器は地上に設置する
ため、ケーブル接続の作業性を考慮してブッシングを変
圧器の側面上部に装着してある。このため、ケーブルが
長くなり、コストアップになるとともに、変圧器の寸法
が大きくなる問題があった。[Problems to be solved by the device] However, since the conventional oil-filled transformer for underground power distribution is installed on the ground, the bushing is mounted on the upper side surface of the transformer in consideration of workability of cable connection. Therefore, there is a problem that the cable becomes long, the cost increases, and the size of the transformer becomes large.
「課題を解決するための手段」 本考案では、地中配電用油入変圧器を支柱の上に設置す
るため、ブッシングが変圧器の側面上部にある必要がな
くなるため、変圧器の下部に、下向きに装着する構造と
した。[Means for Solving the Problem] In the present invention, since the oil-immersed transformer for underground power distribution is installed on the pillar, it is not necessary for the bushing to be on the upper side surface of the transformer. It has a structure to be mounted downward.
「作用」 本考案によると、ケーブル接続時の作業性の向上が計れ
るとともに、ケーブルの取り回しが不用になり、変圧器
を小形化できる。[Operation] According to the present invention, the workability at the time of connecting the cable can be improved, the handling of the cable becomes unnecessary, and the transformer can be miniaturized.

柱５の中を通ってきたケーブル４が接続されている。[Embodiment] FIG. 1 is a structural diagram showing an embodiment of the present invention. First
In the figure, an oil-filled transformer 1 for underground power distribution is fixedly installed on a column 5 by a base 3 provided in the lower part.
Further, a cable 4 rising from the ground and passing through a pillar 5 is connected to a bushing 2 which is mounted downward on the lower part of the oil distribution transformer 1 for underground power distribution.
「考案の効果」 本考案によると、次のような効果がある。"Effect of device" The present invention has the following effects.
（１）変圧器下部にブッシングがあることから、ケーブ
ルを変圧器上部に持っていく必要がなく、ケーブルが短
くて済み、コストダウンを計れる。(1) Since there is a bushing in the lower part of the transformer, it is not necessary to bring the cable to the upper part of the transformer, so that the cable can be short and the cost can be reduced.
（２）ケーブルを、取り回しなしでブッシングに装着で
きることから、作業性が向上するとともに、変圧器を小
形化できる。(2) Since the cable can be attached to the bushing without routing, the workability is improved and the transformer can be downsized.
