この発明に係るガス絶縁誘導機器は、下部端枠の鍔状部
外周部と下部タンクの上端部とを溶接によって一体の構
造物としたものである。Means for Solving Problem C] The gas insulated induction device according to the present invention is constructed by welding the outer circumference of the brim-shaped portion of the lower end frame and the upper end of the lower tank into an integral structure.

送給する。In the present invention, the lower tank and the lower end frame are integrally connected by welding, thereby eliminating the need for packing and, moreover, reliably feeding insulating gas, which is a cooling medium, into the course.
以下この発明の一実施例を図について説明する。 An embodiment of the present invention will be described below with reference to the drawings.

、一体的に結合されている。なお、上部タンク(6a)
は、これら接合された構造物の上方に適宜の手段によっ
て取付けられている。In FIG. 1, (60b) is a lower tank, which is constructed separately from the upper tank (6a). The upper end of the lower tank (60b) is airtightly welded along the circumferential direction to the outer periphery of the flange-shaped portion (51) of the lower end frame (5), and is integrally coupled. In addition, the upper tank (6a)
is attached by appropriate means above these joined structures.

イル外側筒(10)間の空間に流出することがない。し
たがって、ガス流は完全に、コイル(1)及び鉄心(2
)を冷却する通路(3)のみに流れることとなる。The communication port (52) of the lower end frame (5) is reliably connected to the passage (3), and the lower tank (60b) and the lower end frame (5) are airtightly joined by welding. Therefore, the insulating gas does not leak into the space between the tank (6) and the coil outer cylinder (10) as shown in FIG. Therefore, the gas flow is completely connected to the coil (1) and the iron core (2).
) will flow only through the passage (3) that cools the air.
なお、第2図に示した下部端枠(5)の鍔状部(52)
とガス流止め板(11)の間のパツキンが不要となるた
め、不完全接触による、振動、ひびりが発生しなくなる
という付随効果もある。In addition, the flange-shaped portion (52) of the lower end frame (5) shown in FIG.
Since there is no need for a gasket between the gas flow stopper plate (11) and the gas flow stopper plate (11), there is also the additional effect that vibrations and cracks due to incomplete contact are no longer generated.
なお上記実施例では、絶縁ガスをタンク(6)とコイル
外側筒(10)との間の空間には流さない構造としたが
、漏えい磁束によるタンク局部加熱が発ない。In the above embodiment, the structure is such that the insulating gas is not allowed to flow into the space between the tank (6) and the coil outer cylinder (10), but local heating of the tank due to leakage magnetic flux does not occur.
したがって、適正なガス抜き穴を設けることにより、タ
ンクの局部加熱を防止することも可能である。Therefore, by providing appropriate vent holes, it is also possible to prevent local heating of the tank.

用いることができることは言うまでもない。また、絶縁
ガスもSFsガスに限定されるものでないことは当然で
ある。By the way, in the above embodiment, the case where the present invention is used in a gas insulated reactor has been described, but it is not necessarily limited to this, and it goes without saying that it can be used in a gas insulated induction device for boat fishing. Furthermore, it is a matter of course that the insulating gas is not limited to SFs gas.
