Automatic disconnecting device of high-voltage falling type switch

The invention discloses an automatic disconnecting device of a high-voltage falling type switch. The automatic disconnecting device comprises a protection circuit for protecting equipment and an executing mechanism for controlling the high-voltage falling type switch to be automatically switched off, wherein the executing mechanism is connected with the protection circuit; the protection circuit can generate a starting signal to start the executing mechanism connected with the protection circuit to move when the equipment breaks down; and the moved executing mechanism can realize switching-off protection on the switched-off high-voltage falling type switch. The automatic disconnecting device of the high-voltage falling type switch has the advantages of simple structure and reliable movement, and can safely, rapidly and reliably automatically control the switching-off of the high-voltage falling type switch, so that faults can be rapidly and reliably removed and the aim of protecting electric equipment is achi
