接続する。FIG. 3 shows, as a conventional example, the configuration of the connecting portion between the oil-filled transformer and the gas-insulated switchgear. Reference numeral 1 is a tank, and a side wall of this tank is equipped with a pocket 2 provided with a connecting flange on an end surface thereof, and a partition wall 4 provided with an oil-gas bushing 3, a transformer insulating oil 5 and a gas-insulated switch side SF6 gas 6 The gas insulated switchgear sheath 7 is connected to the gas insulated switchgear sheath 7 through a partition with bolts, and the lead wire 9 drawn from the winding 8 is connected to the gas insulated switchgear conductor 10 via the oil-gas bushing 3.

局部応力の緩和、機器間の接続作業を容易としてきた。However, if the sheath 7 is long, the thermal expansion of the sheath 7 may cause repeated stress in the mounting portion of the tank 1 and the pocket 2, which may lead to cracking of that portion, and the transformer and gas on site. It may be difficult to connect the insulation switchgear due to manufacturing tolerances of each device. As shown in FIG. 4, a bellows 11 is inserted between the pocket 2 and the partition wall 4, The bellows 11 has eased the local stress due to thermal expansion and facilitated the work of connecting the devices.

なるという問題があつた。However, in this structure, the number of seals is increased by one place compared to the case of FIG. 3, and the reliability against SF6 gas leakage decreases,
There is a problem that the installation area of the entire device is increased by the length 1 of the bellows 11.
本発明の目的は、電器機器間の接続に関し、シール面の
信頼性向上と機器据付スペースの縮み化及び経済性を向
上することのでき油入電器を提供することにある。It is an object of the present invention to provide an oil-filled electric device which is capable of improving reliability of a sealing surface, shrinking an equipment installation space, and improving economy in connection between electric appliances.

器間を接続することにより達成される。The above purpose is to provide a pocket provided on the side surface of the electric tank with a child pocket having a diameter larger or smaller than the diameter of the pocket, and welding a thin flat wheel plate or a corrugated wheel plate between the different diameters of the pockets by welding. This is achieved by providing a connection flange on the child pocket and directly connecting devices such as a gas-insulated switchgear without using a bellows.

Since it is absorbed by the flexibility of the thin flat wheel plate or the corrugated wheel plate provided in this pocket, there is no excessive local stress on the electric tank and the pocket mounting portion. Further, similarly, the flexibility of the thin flat wheel plate or the corrugated wheel plate facilitates the work of adjusting the connection between the devices, so that the bellows is not necessary.

A corrugated shaft plate 14 as shown in FIG. 2 is welded between the different diameters of the pockets. A flange is provided at the tip of the child pocket 13 and a connecting bolt hole is formed therein. Furthermore SF6
In order to partition the gas 6 and the insulating oil 5, the partition wall 4 having the oil-gas wall bushing 3 mounted thereon is attached to the pocket flange, and the gas insulating switchgear sheath 7 is directly connected. To the wall bushing 3, the lead wire 9 drawn from the winding is connected.
