The invention discloses a method for grounding a fixed contact of a fracture of a handcart type switch by using a grounding wire special for the handcart type switch, relates to the field of power, and aims to solve the problems that an existing grounding wire form cannot be mounted at the fracture of the handcart type switch and the workload of an operator is increased. The method comprises the following steps: plugging the tail end of a plug type contact into the head end of an insulating rod, buckling the head end of a lock catch into a lock catch slot in the tail end of the plug type contact and under the action of a reset spring, so as to complete connection between the plug type contact and the insulating rod, and then connecting the grounding wire to the plug type contact through a bolt; operating the insulating rod to plug the head end of the plug type contact onto the fixed contact of the fracture of the handcart type switch, wherein at the moment, the fixed contact of the fracture of the handcart type switch is connected to the grounding wire through the plug type contact; shifting an operation handle to drive the lock catch through a connection rod for operation, so as to enable the lock catch to be separated from the lock catch slot in the plug type contact, and unplugging the insulating rod from the plug type contact to complete grounding of the fixed contact of the fracture of the handcart type switch. The method is used for grounding the fixed contact of the fracture of the handcart type switch.
