Abstract

The invention discloses a tour inspection and restoration apparatus and method of an outer sheath of a power transmission line, and belongs to the technical field of electric power transmission lines.The apparatus comprises a body arranged on the power transmission line and connected through a travelling mechanism, and an infrared thermal imaging part, a micro camera and a restoration assembly arranged on the body; the micro camera and the restoration assembly are respectively arranged at two sides of the body along an extending direction of the power transmission line through mechanical arms; and the infrared thermal imaging part is arranged at the top of the body and located below the power transmission line. The method includes: monitoring a portion of the power transmission line traveled by the apparatus through the infrared thermal imaging part and the micro camera, analyzing obtained image information, and issuing a maintenance instruction after determining that the outer sheathof the power transmission line is in a damaged state to enable the apparatus to rapidly repair damage points. According to the apparatus and the method, the operation condition of the outer sheath ofthe power transmission line can be grasped in time, the occurrence of faults of the power transmission line can be effectively reduced, and accident hidden risks are eliminated in the bud.

Description

technical field [0001] The invention belongs to the technical field of power transmission lines, and in particular relates to a device and method for inspecting and repairing the outer sheath of a transmission line. Background technique [0002] The outer sheath is the outermost layer of the cable. In recent years, with the increase of the operating life and the harsh operating environment, the damage to the outer sheath of the cable has increased year by year, and the proportion of cable failures caused by damage to the outer sheath of the cable is increasing. Once the outer sheath of the cable is damaged, on the one hand, the main insulation will generate electric field concentration at the corroded metal sheath, which will easily generate partial discharge and cause electric tree branches, which will threaten the short-term operation of the cable, accelerate insulation aging, and reduce the transmission capacity of the cable. Due to the intrusion of water and moisture in ...
