本発明は複数台の単位変圧器によシ分割された高電圧大
容量の変圧器に関する。DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a high-voltage, large-capacity transformer divided into a plurality of unit transformers.
近年、電力需要の増大に伴い、変電機器の8菫も増大し
、現在では500Kv級変圧器が製作運転されておシ、
ざらに大容量高電圧機器も計画されている。このような
大容量変圧器に5つでは、発電所等の臨海地域に設置す

下変電所などに設置する場合には輸送制限から、単相6
単位に分割し、さらに輸送単位を小ざくするためにこの
単相器を分割することが行われる。In recent years, with the increase in electricity demand, the number of substation equipment has increased to 8, and 500Kv class transformers are currently being manufactured and operated.
Large-capacity, high-voltage equipment is also planned. Five large-capacity transformers like this have relatively few restrictions when installed in coastal areas such as power plants, but when installed in mountainous areas or underground substations in urban areas, there are transportation restrictions. single phase 6
This single-phase transformer is divided into units and further divided into smaller transportation units.

態を完全に再現できないばかりでなく、溶接部分の補修
を完全に行わなりと、絶縁耐力を確保することが困難で
ある。In such a case, it is necessary to house each divided unit transformer through a duct, connect the high voltage leads to each other, and draw them out using external couplings for connection. In such a case 5
Because class 00 high voltage leads have a complex insulation structure, it is important to accurately position and assemble the connecting duct on-site to ensure the quality of the transformer. However, on-site fitting work such as welding not only cannot completely reproduce the test conditions in the factory, but also makes it difficult to ensure dielectric strength unless the welded parts are completely repaired.
このような点から単位変圧器の相互位置寸法を確保する
ために例えば特開昭55−120113号公報に示され
るよりに共通基碇ベース上にピンを配置し現地組立の相
互位置を舗保する方法がとらねる。From this point of view, in order to ensure the mutual positional dimensions of the unit transformers, pins are arranged on a common anchor base to maintain the mutual position during on-site assembly, as disclosed in, for example, Japanese Patent Application Laid-Open No. 55-120113. I need a method.
しかしながら、前記のような方法によっても接続ダクト
は通常変圧器の側面あるいは上部にちるため、完全な位
置決めは烈しい。However, even with the above method, the connecting duct is usually attached to the side or top of the transformer, so perfect positioning is difficult.
したがって本発明では上記の欠点を除去して分割された
変圧器の相互組立寸法の確保および、現地組立の簡易化
を計った変圧器を得ることを目的とするものである。Therefore, it is an object of the present invention to eliminate the above-mentioned drawbacks, ensure dimensions for mutual assembly of the divided transformers, and provide a transformer that facilitates on-site assembly.

ある。The present invention relates to a transformer constructed by arranging a plurality of unit transformers in parallel on a common base beam and connecting each unit transformer with a pocket duct. The present invention is characterized in that at least two or more pins and pin fitting holes are provided on the reinforcing beam to fit into each other.
以下本発明を図面をもとに説明する。 The present invention will be explained below based on the drawings.

。3B As shown in FIG. 3, at least two pins 7 and holes 6 to fit the pins are provided on the top. According to such a structure, the unit transformer 61A, xB at the site
Considering the assembly dimensions of the joint in the factory and the hole 6 that fits into the pin 7 for on-site assembly, it is an oval shape with the longitudinal direction at the top and bottom as shown in Figure 4. The shape is such that the position matches the pin position during normal assembly. At the site, final assembly and assembly will be carried out using rollers and cranes. Therefore, after the transformer IB having the pin hole 6 is installed in advance, the transformer IA with the pin 7 attached is installed while making contact with the backing plate using the pin 7 as a guide.
このようにすれば現地における単位変圧器IA。In this way, the unit transformer IA at the site.

ることが少いため組立精度が低下することがない。Since the IB assembly dimensions can be assembled without any discrepancy from the assembly dimensions in the factory, the assembly of the duct parts on site can be controlled with precision. Furthermore, since the main fitting part is provided in the reinforced part of the tank, it is less likely to be deformed during on-site direct air pumping, so there is no reduction in assembly accuracy.

リ、耐振性が向上する。With this structure, the unit transformers are firmly connected to each other, so no excessive force is applied to the ducts during an earthquake, which has the advantage of preventing damage to the ducts and improving vibration resistance.
