Background technique

At present, the closed clamping method is mainly used to replace insulators on UHV DC transmission lines. The general steps of this method are: after two intermediate potential electricians carry the insulation transfer rope and the pulley to the designated working position, they will install the clamps that have been passed on. After being in place, tighten the hydraulic screw, loosen and remove the insulator to be replaced, and then replace and install a new insulator. However, in actual operation, due to the limitation of the active space, and the large diameter and weight of the single insulator, it is very laborious for the operator of the intermediate potential on the insulator string to pick and install the insulator; It is not easy to select the hanging point of the transmission rope for lowering the insulator, and it is very time-consuming and laborious to lower the insulator to be replaced, which reduces the work efficiency and increases the labor intensity of the workers.
