The present embodiment switch cubicle door body be with the specific operation principle of interlock：
The operation carried out when having a power failure：Earthed switch operating shaft rotates clockwise, and drives driver blade 11 to rotate clockwise；Driver blade
11 drive push pedal 12, and to left movement, push pedal 12 promotes power transmission shaft 21 to left movement.Connection fork 22 is hinged with connecting lever 23 by pivot pin,
Into bow-arrow type structure, connecting lever 23 drives locking bar 241 to move downward, to realize the unblock to circuit breaker chamber door.Locking bar 241 is transported downwards
When dynamic, locating part 242 is driven to move downward, locating part 242 drives elastic component 243 to move downward, and the energy storage of elastic component 243 finishes.
Unblock principle equally to cable chamber door is the same, completes simultaneously, and circuit breaker chamber door and cable chamber door unblock finish, and can open
Operated during power transmission：Cable chamber door is first closed, the hyoplastron of cable chamber door, which promotes, closes a connecting lever 42, closes the rotation fortune of a connecting lever 42
Dynamic, drive is closed door lock rod 41 and moved downwards, closes and drives keeper 44 to move downward when door lock rod 41 moves downward, keeper 44
Dynamic clamping head and quiet clamping head 43 is driven to move downward, the energy storage of dynamic clamping head and quiet clamping head 43 finishes.Circuit breaker chamber door could close.Completion order is closed the door
Operation, otherwise, closes door lock rod 41 in the presence of dynamic clamping head and quiet clamping head 43, is inserted into always in circuit breaker chamber door, circuit breaker chamber door
It can not close.
Close after cable chamber door and circuit breaker chamber door, earthed switch operating shaft rotates counterclockwise, while drives driver blade
11 are rotated counterclockwise, and now push pedal 12 is moved to the right by gear drive, are no longer contacted with power transmission shaft 21.Elastic component 243 is released
Exoergic amount, locating part 242 is driven to move upward, locating part 242 drives locking bar 241 to move upwards, and the rotation of connecting lever 23, which drives, to be connected
Connecing fork 22 and power transmission shaft 21, axially left side is moved.Just as projecting bow and arrow, locking bar 241 pins breaker chamber for now whole design
Door, same lower section locking bar 241 pin cable chamber door.
The above embodiments are merely illustrative of the technical solutions of the present invention, rather than is limited；Although with reference to foregoing reality
Example is applied the present invention is described in detail, for the person of ordinary skill of the art, still can be to foregoing implementation
Technical scheme described in example is modified, or carries out equivalent substitution to which part technical characteristic；And these are changed or replaced
Change, the essence of appropriate technical solution is departed from the spirit and scope of claimed technical solution of the invention.
