The invention discloses a local replacing method of an overhead rigid contact hanging contact guide line. The local replacing method comprises the following steps that 1, the part from the serious abraded part to the terminal part of an anchor section on an old contact line in a busbar is removed; 2, the removed part of the old contact line is replaced with a new contact line; and 3, the new contact line is connected with the old contact line. According to the local replacing method of the overhead rigid contact hanging contact guide line, the part from the serious abraded part to the terminalpart of the anchor section on the old contact line in the busbar is wholly removed, the removed part of the old contact line is replaced with the new contact line, and reinforcing treatment is conducted at the butt joint position; and under the situation that operation of an existing line is not affected, local replacing is conducted on the contact line which is abraded seriously in the anchor section, operation and maintenance costs are reduced, and the loss of the busbar is reduced.
