この考案は変圧器、リアクトル、コンデンサなどの密封
形電気機器に用いられるブッシングに関する。[Detailed Description of the Invention] This invention relates to a bushing used in sealed electrical equipment such as transformers, reactors, and capacitors.
この種機器にあってはその寸法の点で輸送制限を受け、
ためにブッシングを取外して輸送しなければならないも
のがある。This type of equipment is subject to transportation restrictions due to its size.
For some products, the bushing must be removed and transported.
ところが、この場合には据付現場においてブッシングの
取付は組立を行なうときに機器の絶縁媒体が大気に触れ
あるいは大気中に散逸することから、現場において再度
機器内部の真空脱気処理を施こさなければならない不都
合がある。However, in this case, when installing the bushing at the installation site, the insulating medium of the equipment comes into contact with the atmosphere or dissipates into the atmosphere during assembly, so it is necessary to perform vacuum degassing inside the equipment again at the installation site. There are some inconveniences that cannot be avoided.
この考案は上述の事柄に鑑み、分割式のブッシングを用

に収納して輸送制限寸法以下としたものである。In view of the above-mentioned issues, this invention uses a split-type bushing, and includes an internal conductor that electrically bridges the connection terminals provided at both ends of the bushing, at least a portion of which has a flexible portion. By constructing the device, the external bushing can be removed without breaking the seal of the container in which the device main body is housed during transportation, and the internal conductor can be stored within the internal bushing to reduce the size to below the transportation limit.

共動して絶縁を図る場合もある。43 and 44 are gaskets, 93 and 94 are flanges, 10 is a mounting base provided on the outer wall of the container 3, 11 is an insulating medium for insulating the main body of the sealed electrical equipment 2, and 12 is a material inside the bushing 1 as required. It is an insulating medium that is filled with the shield electrode 7, and may work together with a solid insulator provided on the outer periphery of the shield electrode 7 to achieve insulation.
１３は前記絶縁媒体１２として絶縁油が用いられた場合
の油量調整を行なうためのチッ素ガスであるが、これに
代て油量調整装置をブッシング１の頭部に設けたＯＦ式
槽構造しても良いのは勿論である。Reference numeral 13 denotes nitrogen gas for adjusting the oil amount when insulating oil is used as the insulating medium 12, but instead of this, an OF type tank structure is provided in which an oil amount adjusting device is provided at the head of the bushing 1. Of course you can do that.
以上の構成によるときは、この種密封形電気機器２を輸
