場等に輸送される大型大重量の変圧器等を吊り上げる分
割輸送変圧器の吊り上げ方法に関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for hoisting a split transportation transformer for hoisting a large and heavy transformer that is disassembled and transported to an installation site or the like.
【０００２】[0002]
【従来の技術】近年電力需要の増大に伴ない送電系統も
５００ｋＶ送電などと高電圧化すると共に、送変電用に
使用される変圧器も大容量化し、大型化と重量化を招い
ている。2. Description of the Related Art In recent years, as the demand for electric power has increased, the power transmission system has become higher in voltage such as 500 kV power transmission, and the transformer used for power transmission and transformation has a large capacity, resulting in an increase in size and weight.
【０００３】また、送電距離も長大化しているために、
この種の変圧器も輸送条件が一段と厳しい山間地等に据
付けることが多く、その輸送寸法と重量の大幅な低減が
必要となっている。Further, since the power transmission distance is also lengthened,
This type of transformer is also often installed in mountainous areas where the transportation conditions are more severe, and it is necessary to greatly reduce the transportation size and weight.
【０００４】従来、このような山間地等に設置する変圧

単相変圧器を３相一括タンク、あるいは共通ダクトによ
り接続結合して３相結線を行なうことにより３相変圧器
として構成している。この種の変圧器は分割輸送変圧器
と称される。Conventionally, in the case of a transformer installed in such a mountainous area, for example, in the case of a three-phase transformer, it is constructed as three single-phase transformers in a factory or the like and transported, and each of them is transported locally. The three-phase transformer is configured by connecting and connecting the three-phase transformer by a three-phase batch tank or a common duct to perform three-phase wiring. This type of transformer is called a split transport transformer.
【０００５】しかしながら、例えば３００ＭＶＡ級の大
型大重量の変圧器を分割輸送変圧器方式で構成した場合
は現地据付スペースや変圧器の経済性等からは３分割ま
でが一般的であり、輸送重量も６０トン程度に低減する
のが限度である。However, for example, when a large and heavy transformer of 300 MVA class is constructed by a split transportation transformer system, it is generally up to 3 divisions from the viewpoint of the installation space and the economical efficiency of the transformer, and the transportation weight is also increased. The limit is about 60 tons.
【０００６】したがって、この種の変圧器を鉄道または
船輸送した後の現地トレーラ輸送に対しては大掛りな橋
梁の補強を含めた道路補強工事が必要となり莫大な輸送
費と時間が必要となる等の課題がある。[0006] Therefore, in order to transport a local trailer after transporting this type of transformer by rail or ship, it is necessary to carry out road reinforcement work including reinforcement of a large bridge, and enormous transport cost and time are required. There are issues such as.
【０００７】そこで輸送上の制約が特にきびしい場合に
は細分分割輸送変圧器方式が考えられる。この方式は工
場で組立てた変圧器を、鉄心脚、上下ヨーク、巻線およ
び分割タンク等の各部分に分解して細分化し、現地でこ
れらを再度組立てる方式である。[0007] Therefore, if there are particularly severe restrictions on transportation, a subdivision transportation transformer method can be considered. In this method, a transformer assembled at the factory is disassembled into parts such as iron core legs, upper and lower yokes, windings and split tanks, which are subdivided, and these parts are reassembled on site.
【０００８】この方式の場合には、最重量構成物となる
鉄心が例えば三相五脚鉄心の場合には、これをさらに分
解して輸送するために、組立後の総重量が例えば約１２
０トンの鉄心でも、最大輸送単位を例えば２０トン程度
に軽量化することができる。このために変圧器輸送上の
制約を軽減することができるので、道路補強なしで工場
から一般トレーラーで現地へ輸送することができる。In the case of this method, in the case where the iron core which is the heaviest component is, for example, a three-phase five-leg iron core, the total weight after assembly is, for example, about 12 in order to further disassemble and transport the iron core.
Even with an iron core of 0 tons, the maximum transport unit can be reduced to about 20 tons. As a result, restrictions on transportation of transformers can be alleviated, and it is possible to transport from the factory to the field by a general trailer without road reinforcement.
【０００９】しかしながら、この場合には、工場組立と
同様に現地においても鉄脚を寝かせ、下部ヨーク積みを
行った後で、重量が１００トンを超える鉄心を起立させ
る等大掛りな起立設備とこれを支持据付ける基礎工事が
必要となる。In this case, however, as in the case of factory assembly, even after locally laying down the iron legs and stacking the lower yoke, a large-scale erection facility such as an iron core with a weight of more than 100 tonnes is erected. The foundation work to support and install is required.
【００１０】さらに、分解された部分の再組立に長時間
を要するため巻線絶縁物が吸湿した場合には長時間にわ
たる乾燥工程が必要となり、変圧器据付工期が大幅に増
大すると共に、異物混入による品質の低下発生等の課題
がある。Further, since it takes a long time to reassemble the disassembled portion, if the winding insulation absorbs moisture, a long drying process is required, which significantly increases the transformer installation period and also prevents foreign matter from entering. There is a problem such as deterioration of quality due to
【００１１】そこで、現地での変圧器組立作業を容易と
するため、従来は鉄心を例えば三相五脚鉄心の場合に
は、図３で示すように分解して輸送していた。すなわち
鉄心主脚１の抜板を脚の幅中央で左右に分離し、下部ヨ
ーク２と一体化した輸送単位のＵ字形鉄心３と、上部ヨ
ーク４に分割している。Therefore, in order to facilitate the work of assembling the transformer on site, conventionally, in the case of a three-phase five-leg iron core, for example, the iron core was disassembled and transported as shown in FIG. That is, the blank of the iron core main leg 1 is separated into left and right at the center of the width of the leg, and is divided into a U-shaped iron core 3 of a transport unit integrated with the lower yoke 2 and an upper yoke 4.
【００１２】この場合、総重量１２０トンの鉄心でも最
大輸送単位を例えば約２５トン程度に軽量化することが
できる。このために、一般トレーラーで道路補強なしで
現地へ輸送することが可能となる。In this case, even with an iron core having a total weight of 120 tons, the maximum transport unit can be reduced to about 25 tons. For this reason, it becomes possible to transport to the site without road reinforcement by a general trailer.
【００１３】また、下部ヨーク２を組み合わせた状態で
起立させたまま輸送するので、細分分解輸送方式の場合
に比べて、現地における再組立工数を減少させ、現地に
おける鉄心起立作業を不要にすることができるといった
利点があった。Further, since the lower yoke 2 is assembled and transported while standing upright, the number of reassembling man-hours at the site is reduced as compared with the case of the subdivision disassembly transportation system, and the iron core standing up work at the site is unnecessary. It had the advantage of being able to
【００１４】しかし、輸送制限としては、一般には重量
制限ばかりではなく、例えば寸法制限があり、特に山岳
地のトンネルや市街地の鉄道ガード等で決まる高さ制限
がきびしいことが多い。However, in general, not only weight restrictions but also dimensional restrictions are imposed as transportation restrictions, and in particular, height restrictions determined by tunnels in mountainous areas or railroad guards in urban areas are often severe.
【００１５】このため大容量変圧器の場合には、図４で
示す低床トレーラー５を使用しても輸送高さ制限をクリ
アできない場合がある。Therefore, in the case of a large-capacity transformer, even if the low floor trailer 5 shown in FIG.

送用タンク６は上、下部６ａ，６ｂどうしを接続してな
る。[0016] Therefore, in the case where the transportation of the large-capacity transformer is severe, and the disassembling transportation method must be applied,
In addition, when the transportation restrictions, especially the transportation dimension restrictions in the height direction are severe, in order to satisfy these transportation restrictions, the iron core 3 is housed in the transportation tank 6 as shown in FIG. There is a method of mounting it on the low-floor trailer 5 in a slanted or inclined state and transporting it to the site. The transportation tank 6 has upper and lower portions 6a and 6b connected to each other.

ージを与え、品質上問題を発生させる虞れがある。However, when the transportation tank 6 is lifted and tilted or laid down, the iron core 3 in the transportation tank 6 is impacted. For this reason, there is a possibility that the iron core 3 that has been verified after being assembled in the factory may be damaged, causing a quality problem.
【００１８】また、現地においては傾斜または横だおし
で輸送された鉄心３を、輸送タンク６ごと起立させるた
めには図５で示す大がかりな起立装置７を必要とする。Further, in order to raise the iron core 3 transported on a slope or sideways together with the transportation tank 6 locally, a large-scale standing device 7 shown in FIG. 5 is required.

After unloading and fixing the erection device 7, it takes time to unload the erection work, and a place for installing the erection device 7 and a work space are required.

It is an object of the present invention to provide a method for hoisting a split transport transformer, which can hoist and unload a transportation container locally in a short time and in a small space.

態の輸送用容器の上端部を傾倒自在に支持して空中に吊
り上げてから、この輸送用容器の下端部の一側端を吊り
上げることにより、この輸送用容器を空中で傾倒させる
ことを特徴とする分割輸送変圧器の吊り上げ方法。1. An upright transport container in which an iron core of a transformer is housed and fixed is tiltably supported and lifted in the air, and then one end of the lower end of the transport container is lifted. Therefore, the method for lifting a split transport transformer is characterized in that the transport container is tilted in the air.
