で、とくに弱点部となる。However, in the connection portion of the insulated conductor thus configured, as described above, the withstand voltage characteristic between the respective phases is strengthened by the shield portion 7 and the insulating tube 4, and the isolation ground is provided. The withstand voltage characteristics between the two correspond to the bottom portion 7a, but the slight gap formed between the bottom portion 7b and the insulating tube 4 shown in FIG. When entering, there is a possibility that the partition plate 12 may be entangled from the corner portion of the rear portion of the central conductor 1 as indicated by a line B in FIG. 4A. Of the two disconnectors 17A, the first phase and the third
As shown in FIG. 3, the phase disconnection portion is bent upward and downward from the middle portion, and since the distance between the phases of the three bus bars is considered to be long, the distance to the partition plate 12 becomes short. , Especially the weak point.

行きが増え、箱体11の奥行きも深くなって設置床面積が
増える。Therefore, a method of increasing the withstand voltage characteristics by lengthening the shielding portion 7 in the lateral direction (that is, the axial direction of the busbar 2) can be considered, but for forming the insulating layer 3 by cast molding. Although the mold is large, it has little effect. Also, a method of increasing the length of the central conductor 1 and the insulating layer 3 protruding rearward from the partition plate 12 can be considered, but then, the rear partition
Since the withstand voltage value against ground with 14 decreases, the depth of the bus room 15B increases, the depth of the box 11 also increases, and the installation floor area increases.

の弱点となる。On the other hand, the insulating tube 4 becomes longer as the front width of the box body 11 becomes wider and the bus bar 2 also becomes longer, so that the core bar becomes longer at the time of manufacture and it becomes difficult to pull out after molding. Not only when assembling the box
A wide working space is required on 11 sides. Therefore, a method of inserting a plurality of short insulating pipes 4 may be considered, but then the abutting portion of each insulating pipe 4 becomes a weak point of insulation between the phase and the ground.
