Live-working drainage wire bracket

Abstract

The invention relates to a live-working drainage wire bracket which is characterized in that a plurality of through holes (21) are uniformly formed in a sleeve (2); the rear end of the sleeve (2) is connected with a fixing device (4) through a T-shaped plate (22); elastic pins (11) in match with the through holes (21) are arranged on a moving rod (1); a fixing clamp (5) is arranged at the end part of the moving rod (1); the fixing device (4) consists of a left semicircular bracket (41) and a right semicircular bracket (42); one end of the left semicircular bracket (41) is hinged with one end of the right semicircular bracket (42); the other end of the left semicircular bracket (41) is fixed on one side of the T-shaped plate (22); the other end of the right semicircular bracket (42) is slightly shrunk and is movably connected with the other side of the T-shaped plate (22), so that the right semicircular bracket (42) can be opened and conveniently fixed on a electric power pole. By adopting the bracket, a live-working drainage wire can be effectively fixed, the times of power outage are greatly reduced, and the reliability in power supply is improved.

Description

technical field [0001] The invention relates to the technical field of electric tools, in particular to a support for a lead wire for live work. Background technique [0002] In accordance with the requirement of "no power outage is the best service", the power supply company vigorously carries out live work. Live work refers to a method of maintenance and testing on high-voltage lines without power outage. Power equipment needs frequent testing and inspection during long-term operation. And maintenance, live work is an effective measure to avoid maintenance blackouts and ensure normal power supply. Among them, the bypass live operation method of the drain line is to use the external drain line to temporarily short the two sides of the same phase of the maintenance equipment and form a stable current loop, so that it is connected in parallel with the equipment; simply speaking, the current passes through the drain line to keep the line charged, and the equipment is It was i...

Among them, the bypass live operation method of the drain line is to use the external drain line to temporarily short the two sides of the same phase of the maintenance equipment and form a stable current loop, so that it is connected in parallel with the equipment; simply speaking, the current passes through the drain line to keep the line charged, and the equipment is It was isolated for maintenance. Although the drainage line bypass live operation method has greatly increased the electricity sales and solved the problem of power outages on the whole line, but on corner poles or towers with complex lines, due to the long drainage line, when both ends are connected, Interruption without any control, strong wind, touch and other reasons cause the jumper to swing naturally, causing the distance between the jumper and the adjacent phase conductor or crossarm to fail to meet the safety distance, prone to two-phase short circuit and ground fault, which is harmful to personal and equipment safety. create a threat
