が一般的である。 Recently, for example, transformers are often used in direct connection with gas switchgear equipment. When the transformer is directly connected to gas switchgear equipment, use expansion joints such as metal bellows between the equipment to absorb assembly tolerances that occur between the equipment during installation or to absorb vibrations that occur between the equipment during operation. It is commonly used for.

ポケツト１２に連通されている。 The conventional structure in this case will be explained with reference to FIG. Reference numeral 1 denotes a transformer tank, in which an iron core 2 and a winding 3 wound around the iron core 2 are stored.
The transformer tank 1 is connected via a bushing pocket 12 and an expansion joint 9 to a gas switchgear 8 supported on a support frame 13. Further, the winding 3 includes a lead wire 4, a wall bushing 5, a lead wire 6,
It is connected to a gas switching device 8 via a wall bushing 7. The transformer tank 1 and bushing pocket 12 are normally filled with insulating oil. Reference numeral 10 denotes a gas detector for decomposed gas in oil, which is connected to the bushing pocket 12 through a pipe 11 in order to detect decomposed gas in oil generated in the oil due to an abnormality in the lead wire 6 or the like.

It is located to avoid Further, the inner diameter D of the butting pocket 12 is determined by ensuring a necessary insulation distance g from the head shield 7B.

３を強固な構造にすることが要求される。 As mentioned above, the purpose of installing the expansion joint 9 is to absorb assembly tolerances or vibrations, but the expansion joints 9 can also be used to absorb other forces other than tolerances during installation or vibrations generated during operation. However, it can expand and contract freely, which can cause problems. For example, when installing the bushing pocket 1
Before injecting insulating oil into the inside of the bushing pocket 12, the inside of the bushing pocket 12 may be evacuated to prevent air from entering. If the pressure during evacuation at this time is pKg/cm 2 , then the following equation (1), F=p×πD 2 /4Kg ……(1), will cause the equipment to be attracted to each other, for example, the support The frame 13 needs to be strong enough to withstand this force. In addition, the pressure increase inside the bushing pocket 12 due to decomposed gas in the oil that occurs when an abnormality occurs inside the bushing pocket 12 is several times the value when vacuuming, and the support frame 1
3 is required to have a strong structure.
本発明は上記の状況に鑑みなされたものであ

電器用接続装置を提供することを目的としたもの
である。 The present invention was made in view of the above-mentioned situation, and an object of the present invention is to provide a connection device for oil-filled electrical appliances that can simplify the support structure from the foundation by reducing the attractive force or repulsive force generated between the devices. This is what I did.

うにしたものである。 In the connection device for oil-filled electrical appliances of the present invention, a connection container filled with insulating oil is provided in the tank of the oil-filled electrical appliance, and it is connected to a gas switchgear through an expansion joint, and there are two connections between the oil-filled electrical appliance and the gas switchgear. When electrically connecting via wall bushing, the sustaining container is equipped with a pressure receiving plate on the gas switching equipment side, and an expansion joint formed smaller than the inner diameter of the connecting container is attached to this pressure receiving plate. .
以下本発明の油入電器用接続装置の一実施例を

然である。 Hereinafter, an embodiment of the oil-filled electrical appliance connection device of the present invention will be described with reference to FIG. 3, where the same parts as those in the conventional art are denoted by the same reference numerals and explanations of the same parts are omitted. Inner diameter of expansion joint 9A
DA is formed to be smaller than the inner diameter D of the butting pocket 12 and is fixed to the pressure receiving plate 12A. Therefore, the pressure-receiving area of the expansion joint 9A is doubled (DA/D), and the pressure pKg/cm 2 of the attraction or repulsion force generated between the devices can also be reduced by twice (DA/D). . In addition, the remaining pressure is applied to the pressure receiving plate 12.
Since the pressure receiving plate 12A is integrated with the butting pocket 12, no attraction or repulsion force is generated between the devices. In addition, between the pressure receiving plate 12A and the head shield 7B,
It goes without saying that a distance g necessary for insulation must be ensured.

くなるので伸縮接手の製作が容易となる。 Since the connection device for oil-filled electrical appliances of this embodiment is configured in this way, it is possible to reduce the suction force or repulsion force generated between the devices, and the decomposed gas in the oil generated in the event of an abnormality can be removed by the pressure receiving plate 12A. Since the path entering the telescopic joint 9A can be blocked, the gas detection sensitivity of the in-oil decomposition gas detector 10 can be improved. Furthermore, since the diameter DA of the telescopic joint 9A is reduced, the manufacturing of the telescopic joint becomes easier.

伸縮接手の内径を小さくすることにより同様の効
果を得ることができる。 In the above embodiment, a case has been described in which the telescopic joint 9A is arranged on the wall bushing 7 side, but the same applies when it is arranged on the wall bushing 5 side. In addition, although we have described the case where the expansion joint 9A is placed on the transformer side, the same effect can be obtained when installing the expansion joint on the gas switch side by reducing the inner diameter of the expansion joint to the extent that insulation allows. be able to.
