【考案の詳細な説明】
本考案は、変圧器やリアクトルなどの高電圧電器装置の
大容量化を図るのに好適な分割型電器装置に関する。[Detailed Description of the Invention] The present invention relates to a split-type electric appliance suitable for increasing the capacity of high-voltage electric appliances such as transformers and reactors.
最近のように電器が高圧、大容量化すると重器では到底
組立輸送ができず、と云って現地組立とすると非常に工
数と費用を要し、かつ信頼性にも欠けるので、電器を輸
送し得る複数のユニットに分割し、これを現地において
共通ブッシングを介して並列接続して大容量器とする分
割型電器装置が製作されるようになって来た。As electric appliances have become high-voltage and large-capacity these days, it is impossible to assemble and transport heavy equipment; however, it is extremely labor-intensive and expensive to assemble on-site, and it is also unreliable, so it is difficult to transport electric appliances. Split-type electric appliances have come to be manufactured in which a large-capacity device is created by dividing the battery into multiple units and connecting them in parallel via a common bushing on site.
このような装置は所要据付面積が小さく耐震性があり、
組み立て易いことが望まれる。Such equipment requires a small footprint and is earthquake resistant.
It is desired that it be easy to assemble.
第１図および第２図は従来の２ユニツトよりなる分割型
単相電器の構成を示す平面図および側面図である。FIGS. 1 and 2 are a plan view and a side view showing the structure of a conventional split-type single-phase electric appliance consisting of two units.
超高圧電器、例えば変圧器の巻線１を備えた中身２を収
容したタンク３および３′内には絶縁媒体、例えば絶縁
油が充填されてユニットを構成し、それぞれ基礎上に並
設しである。The tanks 3 and 3' containing the contents 2 with the windings 1 of an ultra-high voltage electrical appliance, for example a transformer, are filled with an insulating medium, for example an insulating oil, and form a unit, each of which is arranged side by side on the foundation. be.
そして超高圧器では対地絶縁の合理化のため、鉄心の一
方の脚に巻かれた巻線１を上下に２分割し、その中央部
を高圧端とし上下端を段絶縁の低圧端として並列接続す
る。In ultra-high voltage equipment, in order to rationalize ground insulation, winding 1 wound around one leg of the iron core is divided into two halves, upper and lower, and connected in parallel, with the middle part serving as the high-voltage end and the upper and lower ends serving as the low-voltage ends of the stage insulation. .
さらに鉄心の他脚に巻かれた前記と同様な巻線がリード
４により異なる脚の巻線と並列接続される場合が多い。Furthermore, a winding similar to the above-mentioned winding wound around the other leg of the iron core is often connected in parallel with the winding of a different leg by a lead 4.
この場合、従来は前記リード４は並設されたタンク３お
よび３′の対向する側壁３ａおよび３ａ’に該側壁と直
角に設けられたダクト座５を介して突出されたＬ字形ダ
クト６内を貫通して導出されている。In this case, conventionally, the lead 4 was guided through an L-shaped duct 6 that protruded through a duct seat 5 provided at right angles to the opposing side walls 3a and 3a' of the tanks 3 and 3' arranged in parallel. It is led out through.
Ｌ字形ダクト６の上向きの開口部７にはフランジ８が設
けられ、この上向き開口部７は該開口部に対応するフラ
ンジ８の付いた下向き開口部９を両端に備えたコ字状ま
たがりダクト１０により連結されている。The upward opening 7 of the L-shaped duct 6 is provided with a flange 8, and the upward opening 7 is connected to a U-shaped straddling duct 10 having downward openings 9 at both ends with flanges 8 corresponding to the opening. are connected by.
またダクト１０の両開口部７，９間のほは沖央部にはブ
ッシング１１が設置されている。Further, a bushing 11 is installed in the central part between the openings 7 and 9 of the duct 10.
そして前記タンク３および３′より導出されダクト６お
よび１０の中心を通った二つのリード４は前記共通ブッ
シング１１に接続されている。Two leads 4 led out from the tanks 3 and 3' and passing through the centers of the ducts 6 and 10 are connected to the common bushing 11.
上記開口部７を上向きとし、またフランジ８を設けたの
は、これによって前記両タンク３，３′のＬ字形ダクト
の開口部７の多少のズレまたは、またがりダクト１０の
多少の寸法誤差も補償し得るがらである。The reason why the opening 7 is directed upward and the flange 8 is provided is that this compensates for some misalignment of the opening 7 of the L-shaped ducts of both tanks 3, 3' or some dimensional error of the straddling duct 10. As much as possible.
しかし上記の従来の構成ではダクト座５、Ｌ字形ダクト
６、またがりダク） １０が側壁３ａおよび３ａ’と直
角となった一線上にあるため、両タンク３．３′間の距
離が大きくなり、二つのユニットの占める床面積が大き
くなる。However, in the conventional configuration described above, the duct seat 5, the L-shaped duct 6, and the straddle duct 10 are on a line perpendicular to the side walls 3a and 3a', so the distance between the two tanks 3 and 3' becomes large. The floor space occupied by the two units increases.
また前記タンクがほぼ直線の部材により連結されている
ため、いわゆる逃げがなく耐震性に劣る欠点があった。In addition, since the tanks are connected by substantially straight members, there is no relief and the earthquake resistance is poor.
この場合、タンク側壁３ａおよび３ａ’よりＬ字形ダク

＋ｄｚとなる。In this case, if the distance from the tank side walls 3a and 3a' to the center of the opening 7 of the L-shaped duct 6 is dl, and the distance between the centers of the opening 9 of the duct 10 is d2, then the side walls 3a and 3a of both tanks are The distance L1 between ' is Lx=2d1
+dz.
本考案は上記従来の分割電器装置の欠点を除き所要床面
積が小さく、耐震性の優れた分割型電器装置を提供する
ことを目的とする。It is an object of the present invention to provide a split-type electrical appliance that eliminates the drawbacks of the conventional split electrical appliances, requires less floor space, and has excellent earthquake resistance.
この目的は前記り字形ダクトの導出位置を互にずらして
異なる平面位置より突出させることにより達せられる。This objective is achieved by staggering the lead-out positions of the L-shaped ducts so that they protrude from different plane positions.
第３図および第４図は本考案実施例の分割型電器装置の
それぞれ平面図および側面図で、同一符号は前出と同一
機能を有する。3 and 4 are a plan view and a side view, respectively, of a split-type electric appliance according to an embodiment of the present invention, and the same reference numerals have the same functions as those described above.

び３ａ′と直角方向に突出されている。The duct seats 5 are offset from the opposing side walls 3a and 3a' between the tanks 33 and 33' in which the electrical appliance contents 2 are stored, and protrude from different plane positions in a direction substantially perpendicular to the side walls 3a and 3a'. There is.
そして前述第１図および第２図のようにダクト座５には
Ｌ字形ダクト６および該ダクト間を連絡するまたがりダ
クト１０が連結され、ダクト１０に高圧共通ブッシング
１１が設けられる。As shown in FIGS. 1 and 2, an L-shaped duct 6 and a straddle duct 10 connecting the ducts are connected to the duct seat 5, and the duct 10 is provided with a high-pressure common bushing 11.
該ブッシングは気中ブッシングの他にガス絶縁装置につ
ながるブッシング又はスペーサでもよい。The bushing may be a bushing or a spacer connected to a gas insulating device in addition to an air bushing.

り、θが９０°より小さいときは更に小さくなる。In other words, when θ-90°, the line connecting the openings 9 of 10 is the tank 33°33
When the distance d2 is parallel to the side walls 3a and 3a' of the straddle duct 10, the distance d2 between the centers of the openings 9 of the straddle duct 10 becomes smaller, and when θ is smaller than 90°, it becomes even smaller.
なお、上記の説明においてはＬ字形ダクトのタンクへの
取り付けをダクト座５を介して行なったが該座は必ずし
も必要ではなく、直接取り付けてもよい。In the above description, the L-shaped duct was attached to the tank via the duct seat 5, but the seat is not necessarily necessary and the L-shaped duct may be attached directly.

の付いた上向きＬ字形ダクトを突出する。As is clear from the above explanation, in a device in which two electrical appliance units, each of which is housed in a tank, are arranged side by side and equipped with a common bushing, the opposing tank side walls are shifted from each other and are placed at different planar positions. An upwardly directed L-shaped duct projects with a flange at the end.

た。This reduces the distance between the tanks and reduces the installation area.Furthermore, even if the vibrations of the rain tanks differ during an earthquake, the ducts connected to both tanks are connected in a double-shape, creating a so-called escape. The objective was achieved by obtaining a split electric device which can absorb the displacement difference between both tanks and which is easy to assemble due to the provision of an upward flange.

As in 1, it may be common to two units, or it may be provided independently in each unit and connected in parallel.
また以上の説明においてタンク内の巻線を２個としたが
、この数に関係なく本考案は適用される。Furthermore, in the above description, the number of windings in the tank is two, but the present invention is applicable regardless of this number.
