| description | The invention discloses a method for replacing a large yoke plate of an extra-high voltage multi-split conductor, and relates to the field of power transmission line maintenance. At present, when a large yoke plate is replaced, a four-wire lifter and a double-wire lifter are combined for operation, a plurality of wire lifting systems are needed, different sub-wires are extremely easy to move forwards and backwards inconsistently, and after the replacement is finished, the mounting positions of the sub-wires are inconsistent, so that a suspension clamp is inclined. According to the invention, the new fitting comprising the new wire clamp and the new yoke plate is directly adopted, the new fitting is pre-connected with the wire when being a certain distance away from the old fitting, then the old fitting is removed, the new fitting is moved in place and fastened, and then the old fitting is removed. According to the method, after being fixed, the multiple split conductors are regarded as a group of conductors t |
