The utility model discloses a handcart ground wire for a 10kV enclosed bus, comprising a handcart body of a handcart type breaker and three moving-contact conducting rods. A conductive copper bar is arranged in root portions of the moving-contact conducting rods, wherein the three moving-contact conducting rods are short-circuited from the root portions via the conductive copper bar, and the conductive copper bar is connected with the handcart body of the handcart type breaker via bolts. During use, the reformed handcart ground wire for the 10kV enclosed bus is pushed into a shunt switch cabinet of the handcart ground wire for the 10kV enclosed bus, so that moving contacts of the handcart body are connected with static contacts in the switch cabinet, thereby realizing rapid grounding of the 10kV enclosed bus, solving the problem of necessity to hang a ground wire on the bus during power-failure maintenance of the 10kV enclosed bus, eliminating hidden safety troubles, and improving working efficiency.
