。As shown in FIG. 1, the F-I 81 is normally installed in a closed switchboard (hereinafter referred to as the board) 2, and its operation is as described below. That is, when inserting the E-DS 1, the handle 4 is inserted into the end of the operating rod 3 provided at the bottom of the front side of the board 2, and rotated in a predetermined direction. By this operation, the operating rod 3 rotates together, and the rod 5 communicating therewith is moved upward. For this purpose, a lever 6m rotatably connected to the end of the rod 5 and rotatable about the shaft 6 is rotated to drive the blade 8 fixed to the shaft 6 in the direction of the arrow. For this reason, the blade has a fixed contact 10 provided on the main circuit conductor 9.
mating contact. Three blades 8 are provided for three phases, and these are electrically short-circuited to each other and grounded through the shaft 6. Therefore, in the contact state described above, the main circuit conductor 9 is grounded through the blade 8 and the shaft 6. In this type of E-DSI, maintenance and inspection of the operating mechanism are required, but since the main circuit conductor 9 and the operating mechanism are in the same room, for safety reasons, the main circuit conductor 9 side must be checked during maintenance and inspection. The power had to be cut off, which was inconvenient.

おおっている。The movable contacts 14 for three phases are fixed to the surface opposite to the surface on which the hinge 13 is provided on the short-circuiting plate 12 at a predetermined interphase distance using bolts or the like. Further, the upper side of this shorting plate 12 is rotatably attached to a panel 16 via a hinge 15. The panel 16 is attached to the inner surface of the panel 2 so as to completely cover the large foot 6@, which is completely covered by the shorting plate 12 at the portion opposite to the shorting plate 12. An inspection opening 18 is provided on the back side of the board 2 facing this panel 16, and is normally covered with a cover 17.

る。This operation causes the rod 5 to rise and rotate the shaft 6 clockwise in the figure via the lever 6a. For this reason,
The relay (-6b) fixed to the shirt (shirt) 6 also rotates in the same direction, causing the lower side of the shorting plate 12 to rotate upward around the hinge 15 via the connecting rod 11. By this action, the shorting plate 1: The movable contact 14 is fixed to the main circuit conductor 9 and engages with the contact 10 to ground the main circuit conductor 9. When the operating rod 3 is reversed, the shorting plate 12 is fixed. It rotates downward to separate from the contact 10 and completely covers the opening 18 provided in the panel 16. Therefore, the main circuit conductor 9 and B-D are separated by the panel 16 and the shorting plate 12.
When inspecting the operating mechanism that is partitioned off from the operating mechanism section K, it can be safely inspected through the opening 18 by removing the cover 17 fixed to the back side of the panel 2 with bolts or the like.

いため、主回路導体９偶との間の絶縁耐力が向上する。In the above embodiment, the movable contact 14 is provided on the front side of the shorting plate 120, that is, on the side of the main circuit conductor 9, but it may be fixed on the back side of the shorting plate 12, that is, on the operating mechanism 11, as shown in FIG. . In this case, the fixed contact 10 of the main circuit conductor 9
The movable contact 1 is passed through the through hole 20 provided in the short circuit plate 12.
Formed so as to be in contact with 4. In this way, the movable contactor 14 can be safely inspected on the operating mechanism side that is separated from the charging section while the main circuit is being charged. In the case of an octopus, the shorting plate 12
Since no conductive protrusion (movable contact 14) is provided on the surface of the main circuit conductor 9, the dielectric strength between the main circuit conductor 9 and the main circuit conductor 9 is improved.
