Introduction:
    The interlocking device has improved reverse blocking of the backdoor on the basis of the original interlocking device of 5VACY.363.010 earthing switch operating mechanism. When the backdoor is open(sealed plate), the original interlocking can still operate earthing switch, and this interlock can not be operated, the backdoor(sealed plate) should be closed before operation of the earthing switch.
    The working principle of this interlocking device is that it changes the back support to reverse blocking based on the original 5VACY.363.010. When the backdoor(sealed plate) is opened, the pin rod of 13VACY.02.286 moves towards outside the cabinet by a force of the pressure spring, the held block jams the interlocking screw, the earthing switch can not be operated.
