◎Earthing switch operation mechanism interlocking device (Transmission operation of connecting  assembly drawing

◎ Introduction
The interlock device has improved the reverse blocking of the back door on the basis of 5YF.363.010. When the rear door (sealed plate) is open, earthing switch could sill be operated in the original mechanism. But in this mechanism, the rear door (sealed plate) must be closed or the earthing switch could not be operated.
The working principal is that the back support has been turned into reverse blocking based on 5YF.363.010. When the rear door ( sealed plate ) is open, the pushing plunger of 8YF.1407.0402 will move out of the cabinet under the force of door (sealed plate). The interlock shaft will retract to the rear of the cabinet for lockout and the earthing switch could not be operated.
