The invention relates to an anti-maloperation short circuit ground wire based on a positioning bar. The anti-maloperation short circuit ground wire comprises an operating bar (1), a ground clamp (4), a ground wire outgoing end (13), a ground lead (24) and a ground end clamp (5). The ground clamp (4) is connected with the ground lead (24) through the ground wire outgoing end (13). The ground lead (24) is connected with the ground end clamp (5). An electrified warning device (6) is arranged on the side, close to the ground clamp (4), of the operating bar (1). The electrified warning device (6) comprises an anti-maloperation locking device (7). Compared with the prior art, the anti-maloperation short circuit ground wire has the advantages such as safety, reliability and convenience in operation.
