Door, tool extractor is departed from the limitation of switch cabinet door hook and slot, during this, could only be operated after breaker open operation three stations every
Pass is left, on-load point is prevented, closes disconnecting switch, earthed switch；Now, due to the disengaging pair of cabinet door upper surface groove
The limitation of inverted T shaped second blocking lever bottom, the second blocking lever rise under the effect of lift trend, the second perforation and the first perforation
Misaligned, operator can not be acted by spanner to drive screw and the first termination.
10. the method for work of solid insulation cabinet interlock according to claim 9, it is characterised in that：Close cabinet door and close
Process is conducted on lock, after cabinet door is loaded onto rack, the hook and slot of cabinet door declines after tool extractor is linked into, while cabinet door upper surface
Groove is linked into the second inverted T shaped blocking lever bottom, moves down the second operation panel, and the second perforation is alignd with the first perforation, will be true
The arc-chutes separating brake of empty breaker, the non-overhead of connecting lever make the first blocking lever can be under external force in the first blocking lever bottom
Activity can be declined, now, operator can the operation panel of Level Promoting the 3rd, also make the 3rd perforation with first and second perforation align, behaviour
First, second and third perforation can be penetrated by making spanner, and the first termination and drive screw then can be driven to rotate, and make to isolate in three stations
Conducting rod in switching mechanism positioned at driving silk end is from the ground connection position of tri-station isolating switch mechanism warp toward medial movement
Isolated bit reaches conducting position, and in the process, guide block also toward medial movement, passes through side protruding pin and the guide groove mating band of guide block side
Action-oriented plate moves down, and then drives the 3rd blocking lever to move down, and it is spacing to penetrate hole slot progress for protruding pin under the bottom of the 3rd blocking lever；
By breaker closing, the power transmission to load is completed, after breaker closing, connecting lever rotates clockwise, and upper end overhead is in the first interlocking
Bar bottom, the first blocking lever can not move down, and operator can not operate tri-station isolating switch by mobile 3rd operation panel,
Prevent on-load point, close disconnecting switch, earthed switch.
