Description

本発明は、工場試験が完了した後に分解されて輸送される分解輸送変圧器の鉄心輸送装置およびその輸送方法に関する。   The present invention relates to an iron core transport device of a disassembly transport transformer that is disassembled and transported after a factory test is completed, and a transport method thereof.

近年、電力需要の増大に伴い、送電系統も高電圧化するとともに送変電用に使用される変圧器も大容量化し、これに伴い変圧器の大形化、重量増大化が進んでいる。   In recent years, with the increase in electric power demand, the transmission system is also increased in voltage and the transformer used for transmission and transformation is also increased in capacity, and accordingly, the transformer is increased in size and weight.

一方、変圧器が設置される変電所は、山間地や都心部地下などの輸送条件がきわめて厳しい場所に設けられる場合が増加しており、このような場所に設置する変圧器においては、その輸送寸法と重量を大幅に低減することが必要になってくる。   On the other hand, the number of substations where transformers are installed is increasing in places where transportation conditions are extremely severe, such as mountainous areas and underground areas in central Tokyo. It will be necessary to significantly reduce the size and weight.

従来、輸送制限が厳しい場所に設置する変圧器については、例えば三相変圧器の場合は、３台の単相変圧器で構成してそれぞれ別個に輸送し、現地で組み合わせ接続して三相変圧器を構成する分割輸送方式が採用されていたが、道路や橋梁などの使用における輸送上の制約がさらに厳しい場合には、変圧器を分解輸送する方式が採用されるようになってきている。   Conventionally, for transformers installed in places where transportation restrictions are severe, for example, in the case of a three-phase transformer, it is composed of three single-phase transformers, each of which is transported separately, and connected in combination on-site. The divisional transportation method that constitutes the transformer has been adopted, but when the restrictions on transportation in the use of roads and bridges are more severe, the method of disassembling and transporting the transformer has been adopted.

この分解輸送方式の変圧器は、例えば特許文献１に記載されているように、変圧器の工場試験が完了した後、変圧器を本体タンク、鉄心およびコイル等に分解して現地に輸送し、現地において、再度、鉄心にコイルを組み込んで本体タンク内に収納する等の組立作業を行なうことにより組み立てられるものである。   For example, as described in Patent Document 1, the transformer of this disassembly and transportation system is disassembled into a main body tank, an iron core, a coil, and the like after the factory test of the transformer is completed, and is transported to the site. On-site, it is assembled again by performing assembly work such as incorporating the coil into the iron core and storing it in the main body tank.

このような分解輸送変圧器においては、分解した構成部品をそれぞれ輸送用タンクに収納して輸送する方法が一般的であるが、輸送用タンクはその後廃棄物として処分されることが多いことや、輸送用タンクが多くなると輸送用タンクから構成部品を取り出して再組み立てする工程も多くなるという問題があった。   In such a disassembled transport transformer, a method of storing the disassembled components in respective transport tanks and transporting them is common, but the transport tanks are often disposed of as waste afterwards, When the number of transportation tanks increases, there is a problem that the number of steps for taking out components from the transportation tank and reassembling increases.

そこで特許文献１に記載されているように、本体タンクの下部タンクを輸送用タンクとして共用することにより、輸送用タンクを製作する費用や組み立て工程の削減を図ることが提案されている。
特開平６−１９６３４３号公報 Thus, as described in Patent Document 1, it has been proposed to reduce the cost of manufacturing the transport tank and the assembly process by sharing the lower tank of the main body tank as the transport tank.
JP-A-6-196343

しかしながら、上記のように本体タンクの下部タンクを輸送用タンクとして共用しても、その下部タンク上には、鉄心を覆うように輸送用カバーを取り付ける必要があり、この輸送用カバーが大型になっていて、その製作に多大な費用を要したり、輸送時の重量を十分に低減できなかったりするという問題があった。   However, even if the lower tank of the main body tank is shared as a transport tank as described above, it is necessary to attach a transport cover on the lower tank so as to cover the iron core, and this transport cover becomes large. In addition, there is a problem that the production requires a large amount of money and the weight during transportation cannot be sufficiently reduced.

本発明は、上述のような従来技術の問題を解決するためになされたもので、分解輸送変圧器における鉄心の輸送時に、本体タンクの下部タンク上に取り付けられる輸送用カバーの小型、軽量化を図り、変圧器輸送の効率化を図ることを目的とするものである。   The present invention has been made to solve the above-described problems of the prior art, and reduces the size and weight of the transport cover that is mounted on the lower tank of the main body tank when transporting the iron core in the disassembled transport transformer. The purpose is to improve the efficiency of transformer transportation.

上記目的を達成するために、この発明に係る分解輸送変圧器の鉄心輸送装置は、分解された鉄心のうち、少なくとも１個の鉄心主脚と、少なくとも１個の鉄心側脚と、これら鉄心主脚および鉄心側脚を結合する下部ヨークの部分とを組み立てた状態で固定する本体タンクの下部タンクと、前記下部タンクに固定された鉄心部分を覆うように前記下部タンク上に取り付けられ、前記鉄心部分を包囲する部分の水平方向の外形寸法が前記下部タンクの前記鉄心部分を包囲する部分の水平方向の外形寸法よりも小さく構成された輸送用カバーと、を有することを特徴とする。   In order to achieve the above object, an iron core transport device for a disassembled transport transformer according to the present invention includes at least one core main leg, at least one iron core side leg, and the core main body among the disassembled iron cores. A lower tank of a main body tank that fixes a leg and a lower yoke part that joins the iron core side legs in an assembled state, and is mounted on the lower tank so as to cover an iron core part fixed to the lower tank; A transport cover configured to have a horizontal outer dimension of a portion surrounding the portion smaller than a horizontal outer dimension of a portion surrounding the iron core portion of the lower tank.

また、この発明に係る分解輸送変圧器における鉄心輸送方法は、上部タンクと下部タンクとから構成された本体タンクと、この本体タンク内に収容される鉄心および巻線を有する変圧器を仮に組み立て、前記仮組み立ての後に前記上部タンクを外し、前記上部タンクを外した後に前記鉄心の上部ヨークおよび巻線を外し、前記上部ヨークおよび巻線を外した前記鉄心の部分を覆うように前記下部タンクの上に輸送用カバーを取り付け、輸送用カバーを取り付けた状態で前記下部タンクおよび前記鉄心の部分を輸送する分解輸送変圧器における鉄心輸送方法において、前記輸送用カバーは、前記鉄心の部分を包囲する部分の水平方向の外形寸法が前記下部タンクにおける前記分解鉄心を包囲する部分の水平方向の外形寸法よりも小さく構成されていること、を特徴とする。   Moreover, the iron core transport method in the disassembly and transport transformer according to the present invention temporarily assembles a main body tank composed of an upper tank and a lower tank, and a transformer having an iron core and a winding housed in the main body tank, After the temporary assembly, the upper tank is removed, and after removing the upper tank, the upper yoke and the winding of the iron core are removed, and the lower tank is covered so as to cover the portion of the iron core from which the upper yoke and the winding have been removed. In the method of transporting an iron core in a disassembling transport transformer in which a transport cover is attached and the lower cover and the core part are transported with the transport cover attached, the transport cover surrounds the core part. The horizontal dimension of the portion is configured to be smaller than the horizontal dimension of the portion surrounding the dismantling iron core in the lower tank. That you are, characterized by.

本発明によれば、分解輸送変圧器における鉄心の輸送時に、本体タンクの下部タンク上に取り付けられる輸送用カバーの小型、軽量化が可能であり、変圧器輸送の効率化が実現できる。   According to the present invention, it is possible to reduce the size and weight of the transport cover attached on the lower tank of the main body tank when transporting the iron core in the disassembled transport transformer, and it is possible to realize the efficiency of the transport of the transformer.

以下、本発明に係る分割輸送変圧器における鉄心の輸送装置について図面を参照して説明する。ここで、互いに同一または類似の部分には共通の符号を付して重複説明は省略する。   Hereinafter, an iron core transport device in a divided transport transformer according to the present invention will be described with reference to the drawings. Here, the same or similar parts are denoted by common reference numerals, and redundant description is omitted.

図１は本発明に係る分割輸送変圧器における鉄心の輸送装置の第１の実施形態を示す正面図であり、図２はその側面断面図である。図１および図２において、分解輸送変圧器は、工場試験が完了した後、本体タンク、鉄心、コイル等に分解されて現地に輸送される。本体タンクは、分割可能な上部タンクと下部タンクで構成されており、そのうち下部タンク１が輸送用タンクとして共用される。下部タンク１内には、分解鉄心２が固定される。分解鉄心２は、本実施形態における単相３脚鉄心の場合、上部ヨークを取り外した状態の１個の鉄心主脚２ａと、２個の鉄心側脚２ｂ，２ｃと、これら鉄心主脚２ａおよび鉄心側脚２ｂ，２ｃを磁気的に結合する下部ヨーク２ｄを備えており、この分解鉄心２を積層方向両側にクランプ３ａ，３ｂで締め付けて構成されている。   FIG. 1 is a front view showing a first embodiment of an iron core transport device in a divided transport transformer according to the present invention, and FIG. 2 is a side sectional view thereof. 1 and 2, after the factory test is completed, the disassembled transport transformer is disassembled into a main body tank, an iron core, a coil, and the like and transported to the site. The main body tank is composed of an upper tank and a lower tank that can be divided, and the lower tank 1 is shared as a transport tank. A decomposition iron core 2 is fixed in the lower tank 1. In the case of the single-phase three-legged core in the present embodiment, the disassembled iron core 2 includes one iron core main leg 2a with the upper yoke removed, two iron core side legs 2b and 2c, and these iron core main legs 2a and A lower yoke 2d for magnetically coupling the iron core side legs 2b and 2c is provided, and the disassembled iron core 2 is clamped on both sides in the stacking direction by clamps 3a and 3b.

下部タンク１上には、この分解鉄心２を覆うように輸送用カバー４が取り付けられている。この輸送用カバー４は、真空引き等の処理に使用されないので、耐真空等の機械的強度を必要としない簡易な構造で構成されており、しかも図２に示すように、分解鉄心２を包囲する部分の積層方向（水平方向短辺側）の外形寸法Ｗ１が下部タンク１における分解鉄心２を包囲する部分の水平方向の外形寸法Ｗ２よりも小さく構成されている。   A transport cover 4 is attached on the lower tank 1 so as to cover the disassembled iron core 2. Since this transport cover 4 is not used for processing such as evacuation, it has a simple structure that does not require mechanical strength such as vacuum resistance, and surrounds the disassembled iron core 2 as shown in FIG. The outer dimension W1 in the stacking direction (horizontal short side) of the portion to be formed is smaller than the outer dimension W2 in the horizontal direction of the part surrounding the disassembled iron core 2 in the lower tank 1.

またこの輸送用カバー４は、本実施形態の分解輸送変圧器では、タップ切換器５が分解されて別輸送されるので、図１に示すように、輸送用カバー４における分解鉄心２を包囲する部分の水平方向長辺側の外形寸法Ｗ３が下部タンク１における分解鉄心２を包囲する部分の水平方向の外形寸法Ｗ４よりも、タップ切換器５の収納スペ−ス分、小さく構成されている。   Further, the transport cover 4 surrounds the disassembled iron core 2 in the transport cover 4 as shown in FIG. 1 because the tap changer 5 is disassembled and transported separately in the disassembled transport transformer of the present embodiment. The horizontal dimension W3 of the portion in the horizontal direction long side is configured to be smaller than the horizontal dimension W4 of the portion surrounding the disassembled iron core 2 in the lower tank 1 by the storage space of the tap changer 5.

なお、輸送条件を勘案し、必要に応じて分解鉄心２の倒れを防止するために、分解鉄心２の上部には、鉄心主脚２ａおよび鉄心側脚２ｂ，２ｃの上端部を連結するクランプ６ａ，６ｂを積層方向両側に設けて輸送用カバー４に固定することができる。   In consideration of transportation conditions, a clamp 6a for connecting the upper ends of the core main leg 2a and the core side legs 2b and 2c to the upper part of the decomposed core 2 in order to prevent the decomposed core 2 from falling as necessary. , 6b can be provided on both sides in the stacking direction and fixed to the transport cover 4.

このような輸送用カバー４を用いることにより、輸送用カバー４の小型、軽量化が可能となり、本体タンクの下部タンク１を共用することと相俟って、輸送装置の製作コストおよび重量の低減および産業廃棄物の削減を図ることができる。   By using such a transport cover 4, the transport cover 4 can be reduced in size and weight, and combined with the sharing of the lower tank 1 of the main body tank, the manufacturing cost and weight of the transport device can be reduced. In addition, industrial waste can be reduced.

図３は、本発明に係る分割輸送変圧器における鉄心の輸送装置の第２の実施形態を示す正面図である。図３において、本実施形態が第１の実施形態と異なる点は、輸送用カバー７ａ，７ｂ，７ｃを、鉄心主脚２ａおよび鉄心側脚２ｂ，２ｃを個々に覆う複数個により構成したところにある。   FIG. 3 is a front view showing a second embodiment of the iron core transport device in the divided transport transformer according to the present invention. In FIG. 3, this embodiment is different from the first embodiment in that the transport covers 7a, 7b, 7c are composed of a plurality of core core legs 2a and core side legs 2b, 2c that individually cover the core. is there.

Are attached to the lower tank 1 by covering them with independent transport covers 7a, 7b, 7c. By individually configuring the transport covers 7a, 7b, and 7c in a cylindrical shape that resembles the circumscribed circle of each iron core leg, the transport covers 7a, 7b, and 7c can be further reduced in size and weight. Can do.

また輸送用カバー７ａ，７ｂ，７ｃをそれぞれ円筒形に構成することにより、カバー自身の機械的強度が向上するので、この各輸送用カバー７ａ，７ｂ，７ｃで分解鉄心２全体の倒れを防止することができる。これにより第１の実施形態における固定用金具６ａ，６ｂを省略して輸送用カバー７ａ，７ｂ，７ｃの一層の小型、軽量化を図ることができる。   Further, since the transport covers 7a, 7b, and 7c are each formed in a cylindrical shape, the mechanical strength of the cover itself is improved, so that the entire decomposed iron core 2 is prevented from falling by the transport covers 7a, 7b, and 7c. be able to. Accordingly, the fixing brackets 6a and 6b in the first embodiment can be omitted, and the transport covers 7a, 7b, and 7c can be further reduced in size and weight.

なお、輸送中に分解鉄心２が輸送用カバー７ａ，７ｂ，７ｃに接触して破損等が生じないようにするために、必要に応じて間隔片８を配置することができ、または間隔片８の代わりに油圧または空気圧で作動する固定冶具を配置することができる。   In order to prevent the disassembled iron core 2 from coming into contact with the transport covers 7a, 7b and 7c during transportation and causing damage or the like, the spacing piece 8 can be arranged as necessary, or the spacing piece 8 Instead of this, it is possible to arrange a fixing jig that operates hydraulically or pneumatically.

図４および図５は、本発明に係る分割輸送変圧器における鉄心の輸送装置の第３の実施形態を示し、図４はその平面断面図、図５はその正面図である。図４および図５において、本実施形態が第１の実施形態と異なる点は、三相５脚鉄心の場合において、輸送用カバー９ａ，９ｂ，９ｃを、１個の鉄心主脚２ｅまたは２ｆと１個の鉄心側脚２ｂまたは２ｃの組み合わせ全体の断面形状や１個の鉄心主脚２ａの断面形状に合わせて、ある曲率を持った円筒形または部分円筒形に構成したところにある。   4 and 5 show a third embodiment of the iron core transport device in the split transport transformer according to the present invention, FIG. 4 is a plan sectional view thereof, and FIG. 5 is a front view thereof. 4 and 5, the present embodiment is different from the first embodiment in that, in the case of a three-phase five-leg iron core, the transport covers 9a, 9b, 9c are replaced with one iron core main leg 2e or 2f. According to the cross-sectional shape of the entire combination of one iron core side leg 2b or 2c and the cross-sectional shape of one iron core main leg 2a, it is configured in a cylindrical shape or a partial cylindrical shape having a certain curvature.

三相５脚鉄心のように、隣合う鉄心主脚２ｅ，２ｆと鉄心側脚２ｂ，２ｃとの間隔が狭く、輸送用カバーとして円筒形のものを個々の鉄心脚に取り付けられない場合には、隣合う鉄心主脚２ｅまたは２ｆと鉄心側脚２ｂまたは２ｃを組み合わせ、その全体の断面形状に合わせて、輸送用カバー９ｂ，９ｃの断面形状を、例えばダルマ形のように、ある曲率を持たせた部分円筒に構成し、隣合う鉄心主脚２ｅまたは２ｆと鉄心側脚２ｂまたは２ｃを一括収納して下部タンク１に取り付けるようにする。中央部に位置する鉄心主脚２ａは、断面が略円形状であるので、この鉄心主脚２ａに対しては円筒形の輸送用カバー９ａが取り付けられる。このように構成しても、輸送用カバー９ａ，９ｂ，９ｃの機械的強度を維持向上して輸送用カバー９ａ，９ｂ，９ｃの小型、軽量化を図ることができる。   When the space between adjacent core main legs 2e, 2f and core side legs 2b, 2c is narrow, such as a three-phase five-legged core, and a cylindrical cover cannot be attached to each core leg as a transport cover The adjacent iron core main legs 2e or 2f and the iron core side legs 2b or 2c are combined, and the cross-sectional shapes of the transport covers 9b and 9c have a certain curvature, such as a dharma shape, in accordance with the overall cross-sectional shape thereof. It is configured to be a partial cylinder, and the adjacent iron core main legs 2e or 2f and the iron core side legs 2b or 2c are collectively stored and attached to the lower tank 1. Since the core main leg 2a located in the center has a substantially circular cross section, a cylindrical transport cover 9a is attached to the core main leg 2a. Even if comprised in this way, the mechanical strength of the transport covers 9a, 9b, 9c can be maintained and improved, and the transport covers 9a, 9b, 9c can be reduced in size and weight.

図６は、本発明に係る分割輸送変圧器における鉄心の輸送装置の第４の実施形態を示す側面図である。図６において、本実施形態が第１の実施形態と異なる点は、本体タンクの下部タンク１における水平方向の外形寸法を、本体タンクの上部タンク１０における水平方向の外形寸法よりも小さく構成したところにある。   FIG. 6 is a side view showing a fourth embodiment of the iron core transport device in the split transport transformer according to the present invention. In FIG. 6, this embodiment is different from the first embodiment in that the horizontal outer dimension of the lower tank 1 of the main body tank is configured to be smaller than the horizontal outer dimension of the upper tank 10 of the main body tank. It is in.

本体タンクの下部タンク１は輸送用タンクとして共用されるが、この下部タンク１を鉄心の下部ヨ−ク２ｄ近傍で積層方向に絞り込むことによって、その水平方向の外形寸法Ｗ５が、本体タンクの上部タンク１０における水平方向の外形寸法Ｗ６よりも小さくなるように構成している。   The lower tank 1 of the main body tank is commonly used as a transport tank. By narrowing the lower tank 1 in the stacking direction in the vicinity of the lower yoke 2d of the iron core, the horizontal dimension W5 thereof becomes the upper portion of the main body tank. The tank 10 is configured to be smaller than the horizontal dimension W6 in the horizontal direction.

分解鉄心の輸送時、絞り込みによって外形寸法Ｗ５を縮小した下部タンク１上には、この外形寸法Ｗ５よりも小さく構成された輸送用カバー（図示せず）が取り付けられることになる。そして現地において、輸送用カバーが取り外された下部タンク１の鉄心主脚２ａに、別途防湿フィルムによりパックされて輸送されたコイル１１が挿入され、上部ヨーク２ｇが嵌め込まれる等の中身組み立てが行われた後、上部タンク１０が被せられて変圧器が構成される。   When the disassembled iron core is transported, a transport cover (not shown) configured to be smaller than the outer dimension W5 is attached to the lower tank 1 whose outer dimension W5 is reduced by narrowing down. Then, on the site, the coil 11 that has been separately packed and transported with a moisture-proof film is inserted into the core main leg 2a of the lower tank 1 from which the transport cover has been removed, and the contents are assembled such that the upper yoke 2g is fitted. After that, the upper tank 10 is covered to form a transformer.

このようにすれば、輸送用カバーの小型、軽量化とともに下部タンク１の小型、軽量化も図れることになる。   In this way, the transport tank can be made smaller and lighter, and the lower tank 1 can be made smaller and lighter.
