Is shorter than the length between the center conductors held by the two insulating spacers. The total length of the two cylindrical connecting conductors and the slid conductor is longer than the length between the central conductors. When assembling, the two cylindrical connecting conductors are held in advance inside the housing in a state where the two cylindrical connecting conductors are in sliding contact with the sliding conductor and the gap between the two cylindrical connecting conductors is small. Secure the body to the flange faces of the two insulating spacers. Next, one of the cylindrical connecting conductors is connected to one of the center conductors by a manual work or the like through the working opening of the housing. Further, the other cylindrical connecting conductor is slid with respect to the sliding conductor to gradually widen the gap between the two cylindrical connecting conductors. Finally, the other cylindrical connecting conductor is connected to the other central conductor. As a result, the center conductor held by the two insulating spacers is electrically and mechanically used as a busbar by the two cylindrical connecting conductors and the one slidable conductor with which these two cylindrical connecting conductors are in sliding contact with each other.

The depth of the hole, which is the first engaging portion, is made deeper than the height of the protrusion, which is the second engaging portion, and a compression spring is provided in the deep portion of this hole. The total length of the connecting conductor including the protrusions at both ends is longer than the distance between the end faces of the two central conductors facing each other, and the length of the portion of the connecting conductor excluding the protrusion is shorter than the distance between the end faces. Therefore, since the connecting conductor is divided into at least two (or three), it becomes possible to mount the connecting conductor between the two central conductors against the biasing force of the compression spring. The coupling surface of each of the divided portions is provided with a third engaging portion including a concave portion and a convex portion that engages with the concave portion. The biasing force of the compression spring acts so as to press the convex portion and the concave portion of the third engaging portion against each other, so that the connecting conductor is held integrally.

造としてある。Before assembly, the two cylindrical connecting conductors 11 and 12 are in sliding contact with the sliding conductor 13, and the gap L between the two cylindrical connecting conductors 11 and 12 is small. It is held in the inside 15c of the housing 15 by means of, and the housing 15 is fixed to the flange surfaces 8a of the two insulating spacers 8 with the bolts 7. Next, the working opening 17 of the housing 15
From one of the cylindrical connecting conductors (for example,
11) is connected to one of the central conductors 9. Further, the other cylindrical connecting conductor (for example, 12) is slid with respect to the sliding conductor 13 to gradually expand the gap between the two cylindrical connecting conductors 11 and 12. Finally, the other cylindrical connecting conductor (eg
12) is connected to the other central conductor 9. As a result, each of the center conductors 9 held by the two insulating spacers 8 has two cylindrical connecting conductors 11 and 12 and these two cylindrical connecting conductors.

After the assembly is completed, the working opening 17 of the housing 15 is closed, and the inside of the housing 15 is filled with an insulating gas such as SF 6 gas. To disassemble, reverse the above procedure. Here, since the cylindrical connecting conductors 11 and 12 or the slidable conductor 13 are not held by a spacer or the like, they are inclined by the action of gravity. Therefore, it is practically impossible to hold it horizontally as shown in FIG. However, the cylindrical connecting conductor 11 and

作用するため、接続導体は一体に保持される。In the invention described in claim 1, the two cylindrical connecting conductors are provided symmetrically with respect to one sliding conductor inside the housing, respectively, and the total length of the two cylindrical connecting conductors is set. Is shorter than the length between the center conductors held by the two insulating spacers. The total length of the two cylindrical connecting conductors and the slid conductor is longer than the length between the central conductors. When assembling, the two cylindrical connecting conductors are held in advance inside the housing in a state where the two cylindrical connecting conductors are in sliding contact with the sliding conductor and the gap between the two cylindrical connecting conductors is small. Secure the body to the flange faces of the two insulating spacers. Next, one of the cylindrical connecting conductors is connected to one of the center conductors by a manual work or the like through the working opening of the housing. Further, the other cylindrical connecting conductor is slid with respect to the sliding conductor to gradually widen the gap between the two cylindrical connecting conductors. Finally, the other cylindrical connecting conductor is connected to the other central conductor. As a result, the center conductor held by the two insulating spacers is electrically and mechanically used as a busbar by the two cylindrical connecting conductors and the one slidable conductor with which these two cylindrical connecting conductors are in sliding contact with each other. Connected. In the invention described in claim 2,
The first engaging portion provided on the central conductor is, for example, a hole having a predetermined diameter, and the second engaging portions provided on both ends of the connecting conductor.
The engaging portion is a cylindrical protrusion having a diameter slightly smaller than the predetermined diameter. The depth of the hole, which is the first engaging portion, is made deeper than the height of the protrusion, which is the second engaging portion, and a compression spring is provided in the deep portion of this hole. The total length of the connecting conductor including the protrusions at both ends is longer than the distance between the end faces of the two central conductors facing each other, and the length of the portion of the connecting conductor excluding the protrusion is shorter than the distance between the end faces. Therefore, since the connecting conductor is divided into at least two (or three), it becomes possible to mount the connecting conductor between the two central conductors against the biasing force of the compression spring. The coupling surface of each of the divided portions is provided with a third engaging portion including a concave portion and a convex portion that engages with the concave portion. The biasing force of the compression spring acts so as to press the convex portion and the concave portion of the third engaging portion against each other, so that the connecting conductor is held integrally.
