きず、保守点検作業が行い難い欠点がある。In the conventional example shown in FIG. 5, when the interval l between the device-side bushings 2 is different, a plurality of short-circuit grounding plates are required. By making the hole of the short-circuit ground plate 6 a long hole, a certain change in the interval l can be tolerated, but it cannot cope with a large change. In addition, since only one of the three phases is disconnected from the ground and the withstand voltage test of the cable cannot be performed, there is a disadvantage that it is difficult to perform maintenance and inspection work.

があった。In the conventional example shown in FIG. 6, in order to improve the maintenance and inspection workability of the above-mentioned conventional example, a ground wire is machined in a fork shape so that the ground can be taken for each phase. (A), when flowing from the cable 5 side to the three-phase batch compression section 9c, large electromagnetic repulsion is generated in the directions of Fx shown in (b) and Fy shown in (a), and the terminal section There was a problem in that rotation of 9a and excessive bending stress on the bushing portion 2 were applied. (In the conventional example shown in FIG. 5, the current flows through the bolted short-circuited ground plate 6, so that the electromagnetic repulsion is reduced and the force applied to the bushing 2 is small.) When tightening and fixing to the adapter with hexagon bolts, the hexagon bolts tended to be lost.
