にはSF6ガス等が充填され、その気密はＯリング
等によつて保持されている。 Generally, in this type of equipment, an insulating spacer supporting a high voltage conductor is sandwiched between flanges of adjacent sealed containers and tightened with bolts. The sealed container is filled with SF 6 gas or the like, and its airtightness is maintained by an O-ring or the like.
絶縁スペーサは円周上に複数の埋込金具を有

因となつてＯリング当り面まで腐食が進展して気
密保持ができなくなる危険があつた。 However, in conventional devices of this type, the embedded metal fittings and bolts corrode due to the infiltration of rainwater, and this causes corrosion to progress to the O-ring contact surface, posing the risk that airtightness cannot be maintained.

知の方法を選択して採用することができる。 In the embodiment shown in FIG. 1, an insulating spacer 12 supporting a high voltage conductor 1 is sandwiched between flanges 4, 5 of a pair of adjacent sealed containers 2, 3. A plurality of bolt insertion holes 6 are formed on the circumference of both flanges, and embedding fittings 13 are embedded in the insulating spacer 12 in correspondence with the holes 6. Furthermore, an annular recess 8 larger than the embedded fitting 13 is formed on the opposing surfaces of the flanges 4 and 5 corresponding to the embedded fitting 13, and the end of the embedded fitting 13 is positioned approximately concentrically within this recess 8. are doing. A single or double annular groove 9 is formed inside this recess, and an O-ring is disposed within this groove 9. In this example, a female thread is formed in the inner wall of the hollow part of the embedded fitting 13, and the bolt 7 is screwed together to fix the flange 4 and the insulating spacer 12. However, a well-known method may be selected and adopted. I can do it.

い。 After this configuration is completed, a liquid gasket is injected through the inlet 10 that opens the recess 8 to the outside air. The liquid gasket passes through the recess 8 to the bolt 7.
It is filled up to the inside of the hole 6 around the . At this time, instead of the injection port 10, the liquid gasket may be filled through the hole 6 from which the bolt 7 has been removed. The filled liquid gasket forms a ring around the outer periphery of the O-ring, which can prevent corrosion due to water seepage into the flange. When the liquid gasket is injected through the hole 6, the bolt that was removed after injection can be tightened, and when the injection port 10 is used, the injection port 10 is plugged. If the material of the liquid gasket is room-temperature vulcanizable rubber, it will harden into a rubber-like state within a few days after filling, so there is no need to plug it.
凹部８はフランジ４および５の対向面両方に設
けても効果は同じである。 Even if the recesses 8 are provided on both opposing surfaces of the flanges 4 and 5, the same effect can be obtained.

の浸水による腐食を防止することができる。 As explained above, in the present invention, a recess is formed with a larger outer diameter than the embedded metal fitting, this recess is communicated with a bolt insertion hole, and these spaces are filled with a liquid gasket, so that the flange near the O-ring It is possible to prevent corrosion of bolts and embedded fittings due to water ingress, which progresses as surface corrosion.
