The first arc-shaped hole and the second arc-shaped hole correspond to the linkage end positions, and a linkage shaft fixedly connected to the linkage end enters the rear side of the control panel 400 through the first arc-shaped hole and the second arc-shaped hole and is fixedly connected to the interlocking plate 5 arranged on the rear side of the control panel 400. The first curtain plate 2 'and the second curtain plate 7' are matched with the arc-shaped holes and the linkage shaft to respectively form a first shielding structure and a second shielding structure for shielding the operation holes of the isolating switch 200 and the grounding switch 300.
The interlocking plate 5 includes a body which is movably fitted to the control panel 400 up and down and is movable between the first interlocking sleeve 1 and the second interlocking sleeve; a locking linkage sheet 503 which is connected with the main body and can be matched with the movable rod 901 of the locking electromagnet 9 in an inserting way, and a locking hole is formed on the locking linkage sheet 503; and a handle for being fitted on the front side of the control panel 400, as shown in fig. 3, inserted from the rear side of the control panel 400 to the front side of the control panel 400 through the handle hole 43, so that the operator controls the movement of the interlocking plate 5. The initial position of the locking hole corresponds to the position of the movable bar 901 of a latching electromagnet 9.
As described above, the first baffle structure or the second baffle structure can be in linkage fit with the interlocking plate 5, and when the latching electromagnet 9 loses power, the movable rod 901 is in insertion fit with the locking hole to limit the movement of the interlocking plate 5, so that the first baffle structure and the second baffle structure respectively shield the operation hole of the disconnecting switch 200 and the operation hole of the grounding switch 300.
