【発明の詳細な説明】 ［発明の目的］ （産業上の利用分野） 本発明は保護ケース付乾式変圧器における組立構造に
関する。DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to an assembly structure in a dry transformer with a protective case.
（従来の技術） 従来の保護ケース付乾式変圧器の一例を第３図につい
て説明する。(Prior Art) An example of a conventional dry transformer with a protective case will be described with reference to FIG.
第３図において、鉄心2aおよびコイル2bを有する変圧
器本体１にはコイル2bと鉄心2aを保持する締付金物３が
設けられている。この締付金物３は鉄心2aの両脚部およ
び下部継鉄部を覆う断面コ字形の下部締付金物3aと鉄心

ース５内に設けたベース６上に載置し、固定ボルト７に
より固定用金物４とベース６を一体に固定することによ
り保護ケース付乾式変圧器が構成されている。In FIG. 3, a transformer body 1 having an iron core 2a and a coil 2b is provided with a clamp 3 for holding the coil 2b and the iron core 2a. The fastener 3 is a lower fastener 3a having a U-shaped cross section that covers both legs and the lower yoke of the iron core 2a and the iron core 2a.
It consists of an upper clamp 3b having a U-shaped cross section that covers the upper yoke part of 2a, and the fixture 4 provided on the lower clamp 3a is placed on the base 6 provided in the protective case 5 and fixed. A dry type transformer with a protective case is configured by integrally fixing the fixing hardware 4 and the base 6 with the bolt 7.
（発明が解決しようとする課題） しかして、従来の保護ケース付乾式変圧器には次のよ
うな欠点がある。すなわち、 （１）従来の保護ケース付変圧器では、その高さが保護
ケース５のベース６の高さ分だけ高くなる。このベース
６の高さは変圧器本体１の重量を支えるために本体重量
が重くなる程高くしなければならず、寸法制限等がある
場合は不利である。(Problems to be Solved by the Invention) However, the conventional dry transformer with a protective case has the following drawbacks. That is, (1) In the conventional transformer with a protective case, its height is increased by the height of the base 6 of the protective case 5. In order to support the weight of the transformer main body 1, the height of the base 6 must be increased as the weight of the main body becomes heavier, which is disadvantageous when there are dimensional restrictions or the like.
（２）従って、寸法制限等により変圧器高さを低くしな
ければならないときは、第４図に示すように、形鋼材か
らなるベース６を伏せた形で使用するが、この場合強度
的に弱くなるためベース６の個数を増加したりあるいは
補強を入れたりするため変圧器の全重量が増加する。(2) Therefore, when it is necessary to reduce the height of the transformer due to dimensional restrictions, etc., as shown in FIG. 4, the base 6 made of shaped steel material is used in a flat shape. Since it becomes weaker, the number of bases 6 is increased or reinforcement is added, so that the total weight of the transformer is increased.
（３）また、変圧器本体１をベース６上に固定すると重
心位置が高くなり、輸送あるいは耐震強度を上げるため
にベース６長さを長くしなければならず、そのため保護
ケース５全体が大きくなり、これにより重量が増加す
る。(3) Further, when the transformer main body 1 is fixed on the base 6, the position of the center of gravity becomes high, and the length of the base 6 must be lengthened in order to increase transportation or seismic resistance, so that the entire protective case 5 becomes large. , Which increases the weight.
本発明は上記した従来の保護ケース付乾式変圧器の欠
点をなくして、小型，軽量で耐震強度が向上する保護ケ

る。SUMMARY OF THE INVENTION It is an object of the present invention to provide a dry transformer with a protective case, which is small in size and lightweight and has improved seismic strength, while eliminating the above-mentioned drawbacks of the conventional dry transformer with a protective case.
［発明の構成］ （課題を解決するための手段） 上記目的を達成するために、本発明は保護ケースを有

寸法を変圧器本体の下部締付金物の長さより大きくし、
当該ベース間に前記変圧器本体の下部締付金物部を落し
込むとともに当該下部締付金物部とベースとを一体に固
定したことを特徴とするものである。[Means for Solving the Problems] (Means for Solving the Problems) In order to achieve the above object, the present invention provides a dry transformer having a protective case, in which a dimension between bases in the protective case is tightened at a lower portion of a transformer body. Larger than the length of the hardware,
The lower clamp metal part of the transformer body is dropped between the bases, and the lower clamp metal part and the base are integrally fixed.

ことができる。(Operation) Therefore, according to the dry transformer with a protective case of the present invention, since the lower clamp metal part of the transformer body is dropped into the space between the bases of the protective case, the height of the protective case is substantially higher than that of the base. Since the height of the dry type transformer with a protective case is lowered, the position of the center of gravity is lowered and the seismic strength can be improved.
（実施例） 本発明の実施例を図面を参照して説明する。(Example) The Example of this invention is described with reference to drawings.
第１図および第２図は本発明の一実施例の正面図およ
び側面図である。1 and 2 are a front view and a side view of an embodiment of the present invention.

圧器本体１の下部締付金物3a部を落し込んで固定用金物
４をベース６上に溶接またはボルト７により固定する。In the figure, a transformer main body 1 has, for example, a dry coil 2b and a core 2a which are molded, and these are held by an upper clamp 3b and a lower clamp 3a having a U-shaped cross section. The lower tightening hardware 3a is provided with a fixing hardware 4 for fixing the transformer body 1, and the transformer body 1 is fixed to the base 6 in the protective case 5 via the fixing hardware 4. . The base 6 of the protective case 5 is arranged with a gap larger than the longitudinal length of the lower clamp 3a covering the lower yoke portion of the iron core 2a, and the transformer main body is placed in the space between the bases 6. The lower tightening metal 3a of 1 is dropped and the fixing metal 4 is fixed on the base 6 by welding or bolts 7.
上記したように、本実施例の保護ケース付乾式変圧器
では、変圧器本体１の下部を保護ケース５内のベース６
間に落し込むため、略ベース６の高さ分だけ保護ケース
５の高さを低くできる。また、重心高さＨも保護ケース
５を付けない場合と殆ど同じで低くなるので耐震強度が
向上する。つまり、変圧器の静的耐震強度はH/Y（Ｈは
重心高さ,Yはベース長さ）で決まるため重心高さＨが小
さくなればそれだけ耐震強度が向上し、また同じ耐震強
度であればベース長さＹを小さくすることができる。As described above, in the dry transformer with a protective case of this embodiment, the lower portion of the transformer body 1 is provided with the base 6 inside the protective case 5.
Since it is dropped in between, the height of the protective case 5 can be lowered by about the height of the base 6. Further, the height H of the center of gravity is almost the same as in the case where the protective case 5 is not attached, and is lowered, so that the seismic strength is improved. In other words, the static seismic strength of the transformer is determined by H / Y (H is the height of the center of gravity, Y is the base length), so the smaller the height H of the center of gravity is, the more the seismic strength is improved. For example, the base length Y can be reduced.
したがって、本実施例によると、下記のような効果を
有する。Therefore, according to this embodiment, the following effects are obtained.
（１）保護ケース５の高さが低くなり、またベース長さ
Ｙを長くする必要がないため保護ケース５が小形で軽量
となる。(1) Since the height of the protective case 5 is low and it is not necessary to increase the base length Y, the protective case 5 is small and lightweight.
（２）重心高さＨが保護ケースなしの場合と殆ど同一の
ため、ベース６が取付けられた分だけ耐震強度は向上す
る。つまり、ベース長さＹが同一ならば重心高さＨが小
さくなった分だけ耐震強度が向上する。(2) Since the height H of the center of gravity is almost the same as that without the protective case, the seismic strength is improved by the amount of the base 6 attached. That is, if the base length Y is the same, the seismic strength is improved by the amount that the height H of the center of gravity is reduced.
（３）変圧器本体１の本体固定部から重心高さ位置まで
の高さ寸法ｈが小さくなり、耐震強度を小さくできるの
で固定ボルト７のサイズを小さくできる。(3) Since the height dimension h from the main body fixing portion of the transformer main body 1 to the center of gravity height position is reduced, and the seismic resistance can be reduced, the size of the fixing bolt 7 can be reduced.
なお、下部締付金物3aと床面との隙間Ｄ寸法は０でも
問題はない。There is no problem even if the size D of the clearance between the lower clamp 3a and the floor is zero.

用金物４とベース６間に挿入すれば、重心高さＨが小さ
いため揺れ振幅が小さくなって安定した変圧器となる。The above embodiment is a single-phase inner iron type transformer, but the same effect can be obtained with other transformers, for example, three-phase, outer iron type transformers, with the same configuration. Further, although the fixing hardware 4 of the transformer main body 1 is L-shaped, the same effect can be obtained even if it has another shape or is directly connected depending on the weight of the transformer main body 1. Further, the protective case 5 may be supported on the transformer body 1 without being fixed to the base 6. When installing the vibration proof rubber, if it is inserted between the fixing hardware 4 and the base 6, the height H of the center of gravity is small and the swing amplitude is small, so that a stable transformer is obtained.
［発明の効果］ 以上説明したように、本発明の保護ケース付乾式変圧
器によると次のような効果を奏する。[Advantages of the Invention] As described above, the dry transformer with a protective case of the present invention has the following advantages.
（１）耐震強度が向上する。(1) Seismic strength is improved.
（２）変圧器本体固定ボルトを小サイズにできる。(2) The transformer body fixing bolt can be made smaller.
（３）小形で軽量の保護ケース付乾式変圧器が得られ
る。(3) A compact and lightweight dry transformer with a protective case can be obtained.
