本考案は、三相負荷時タップ切換変圧器を巻線と鉄心等からなる単相変圧器３ 台に分割してそれぞれ別々の単相変圧器タンクに収納して輸送し、負荷時タップ 切換装置と前記単相変圧器とを据付現地で組立てることにより構成される分割輸 送形三相負荷時タップ切換変圧器に関し、特にその負荷時タップ切換装置の配置 構成に関するものである。 The present invention divides a three-phase load tap change transformer into three single-phase transformers consisting of a winding wire and an iron core and stores them in separate single-phase transformer tanks for transportation.

変圧器は製作工場において完全に乾燥処理を行い、高い絶縁強度が保たれてい る。これを据付現地まで輸送するにはできるだけ分解程度を少なくして途中で吸 湿しないようにし、据付現地における再組立あるいは再乾燥の手数を省き、据付 工事日数を短縮することが望ましい。しかし、三相変圧器が超大形になると、輸 送上の制約から単相変圧器３台に分割して別々の単相変圧器タンクに収納し、負 荷時タップ切換装置も負荷時タップ切換装置タンクに収納して輸送し、据付現地 でリード線を接続し、再組立する構造が採用されている。 The transformer is completely dried at the manufacturing plant to maintain high insulation strength. In order to transport this to the installation site, it is desirable to reduce the degree of decomposition as much as possible so that it does not absorb moisture during the process, eliminate the reassembly or re-drying work at the installation site, and shorten the installation work days. However, if the three-phase transformer becomes super-large, it will be split into three single-phase transformers and stored in separate single-phase transformer tanks due to transportation restrictions, and the tap switching device during load will also switch taps during load. A structure is adopted in which the equipment is stored in a tank and transported, and the lead wires are connected at the site of installation and reassembled.

In FIGS. 12 and 13, a winding 1 and an iron core 2, etc. are respectively formed. When the single-phase transformer main body 3 is stored in the separate single-phase transformer tanks 4A, 4B, and 4C, and the three single-phase transformers 5A, 5B, and 5C are stored in the tap tap changer tank 25 under load. The tap changer 26 and the duct 27 are transported separately, and at the site of installation, the load tap changer stored in the three single-phase transformers 5A, 5B, 5C and the load tap changer tank 25. 26 are arranged side by side, and are connected by an insulating lead wire 28 housed inside the duct 27, and the single-phase transformer tanks 4A, 4B, 4C and the load tap switching device tank 25 are connected via the duct 27. By connecting them together, a split transport type three-phase load tap switching transformer is constructed.

しかし、このような従来の分割輸送形三相負荷時タップ切換変圧器の構成では 各単相変圧器と負荷時タップ切換装置との距離が遠いため、 （１）三相変圧器としての所要設置面積が大きく、建屋に入れる場合は建屋が大 きくなり、防音壁を取付ける場合も据付床面積が大きくなる。 However, in such a conventional configuration of the split transport type three-phase load tap change transformer, the distance between each single-phase transformer and the load tap change device is long, so (1) Required installation as a three-phase transformer Since the area is large, the building becomes large when it is put in the building, and the installation floor area becomes large when the soundproof wall is installed.
【０００５】 （２）各単相変圧器間および各単相変圧器と負荷時タップ切換装置との間の接続 リード線の長さが長く、絶縁を施したリード線が多数であるため、絶縁リード線 の全長が長くなるのでコストが高くなる。(2) Connection between the single-phase transformers and between the single-phase transformers and the tap switching device during load Since the length of the lead wire is long and the number of insulated lead wires is large, insulation is provided. Since the total length of the lead wire is long, the cost is high.
【０００６】 （３）リード線が長いために輸送の制限等から接続箇所が多くなり、工場と現地 とも接続に長時間を要しコストが大となり、品質の面からも好ましくない。(3) Since the lead wire is long, the number of connection points increases due to transportation restrictions and the like, which requires a long time for connection between the factory and the site, resulting in high cost, which is not preferable in terms of quality.
【０００７】 （４）接続リード線を収納するダクトが大きいため油量が大である。(4) The amount of oil is large because the duct that houses the connecting lead wire is large.
【０００８】 （５）ダクトの輸送が困難である。(5) It is difficult to transport the duct.
【０００９】 などの課題があった。There are problems such as the above.
【００１０】 本考案は、以上のような点に鑑みてなされたもので、設置面積、絶縁油量およ び変圧器重量が小さく、輸送が容易で絶縁の信頼性が高い分割輸送形三相負荷時 タップ切換変圧器を提供することを目的とする。The present invention has been made in view of the above points, and has a small installation area, a small amount of insulating oil, a transformer weight, easy transportation, and high insulation reliability. It is intended to provide a tap change transformer under load.

上述の目的を達成するため、本考案の分割輸送形三相負荷時タップ切換変圧器 では、負荷時タップ切換装置と１台の単相変圧器を前後に配置し残り２台の単相 変圧器をその両側に配置するか、あるいは負荷時タップ切換装置と単相変圧器本 体を単相変圧器タンクに収納した単相変圧器と負荷時タップ切換装置を単相変圧 器タンクに収納していない残り２台の単相変圧器を並行に配置するとともに、ダ クトの内部に収納する絶縁リード線により前記各単相変圧器と負荷時タップ切換 装置を結線し、前記各単相変圧器タンクを前記ダクトを介して接続するように構 成することによって、設置床面積を小さくし、接続リード線の短縮、絶縁油量お よび変圧器重量の減少を図っている。 In order to achieve the above-mentioned object, in the split transportation type three-phase load tap change transformer of the present invention, the load change tap changer and one single-phase transformer are arranged at the front and rear, and the remaining two single-phase transformers. Are placed on both sides of it, or the load tap changer and the single-phase transformer are stored in a single-phase transformer tank.The single-phase transformer and load tap changer are stored in the single-phase transformer tank. The remaining two single-phase transformers are arranged in parallel, and each of the single-phase transformers is connected to the tap switching device during load by an insulating lead wire housed inside the duct. The installation floor area is reduced, the connecting lead wires are shortened, and the amount of insulating oil and the weight of the transformer are reduced.

Is a single-phase transformer in which the load tap changer and the single-phase transformer body are stored in a single-phase transformer tank, and two single-phase transformers in which the load tap changer is not stored in the single-phase transformer tank. Since either one of them is installed in parallel, the transformer installation area can be reduced, the number of connection points of the insulation lead wires between each single-phase transformer is reduced, and the connection between the production plant and the installation site is reduced. It will be easier and the connection work time can be shortened. This reduces the opening time of the single-phase transformer tank, improves the reliability of insulation, greatly reduces the size of the connecting duct, reduces the amount of insulating oil and transformer weight, and facilitates transportation.
