Problems solved by technology

However, on the 110KV power transmission line, the tensile tension of the cable is huge, and it is not easy to replace one of the tension insulator strings, and it is necessary to work at high altitude with electricity, which makes the operation more difficult. Therefore, a Assembled replacement tool can facilitate the replacement of tension insulator strings when working at heights

Abstract

The invention discloses an assembled tension insulator string replacement tool. The tool includes a tower head end clamp, a wire end clamp and a tension unit, wherein the tower head end clamp includes a connecting buckle and is connected to the connecting rod. The force-bearing components on both sides of the buckle; the wire end clamp, including a fixed buckle and tension components arranged at both ends of the fixed buckle; and a tension unit connected between the tower head end clamp and the wire end clamp, It includes a support rod and a tension rod assembly; the replacement tool in the present invention has a simple assembled structure, and the clamp at the tower head end is used to cooperate with the connecting wire clamp at the tower head end, and the clamp at the wire end is used to cooperate with the connecting wire clamp at the tower head end. The clamps at the cable end are fixed together, and the tension unit shares the tension on both sides of the tension insulator string by connecting the clamps at the tower head and the clamp at the wire end on both sides, so as to facilitate its replacement.

Description

technical field [0001] The invention relates to the technical field of electrical equipment tools, in particular to an assembled tension insulator string replacement tool. Background technique [0002] Tensile insulator strings are the most common products used in the wiring of transmission lines today. They are used together with supporting power fittings. According to construction needs, several products are stringed together to meet the tension requirements. On the existing 110KV power transmission line, with the increase of service time, the tension insulator strings in the line need to be regularly inspected, and the strain insulator strings that are damaged or fail to meet the tensile requirements need to be replaced. However, on the 110KV power transmission line, the tensile tension of the cable is huge, and it is not easy to replace one of the tension insulator strings, and it is necessary to work at high altitude with electricity, which makes the operation more diff...
