Abstract

The invention discloses a drainage wire protection device of a UHV power transmission line. The drainage wire protection device comprises a power transmission line body, wherein the power transmission line body is sleeved with a protection sleeve, an opening is formed in the front side of the protection sleeve, accommodating grooves are formed in the left side and the right side of the bottom part of the inner wall of the opening, and positioning blocks are positioned and mounted on the left and right sides of the inner walls of the two placement grooves. According to the drainage wire protection device, the power transmission line body, the protection sleeve, the opening, the placement groove, a positioning block, a support column, the placement groove, a fixing mechanism, an annular positioning groove, an annular positioning block, a threaded sleeve, a threaded rod, a square groove, an extrusion device, a square baffle block, an extrusion block, an extrusion spring, a positioning sleeve, an auxiliary mechanism, an elastic rod, a circular block, a support rod, a limiting block, a limiting groove, a matching groove and an insulating tape are used cooperatively, so that the problem of poor protection effect in the prior art is solved, and the drainage wire protection device for the UHV power transmission line has the advantage of good protection effect. The drainage wire protection device is suitable for UHV power transmission lines.

Description

technical field [0001] The invention belongs to the technical field of electric wires, and in particular relates to a protective device for draining wires of UHV transmission lines. Background technique [0002] Wires and cables are used to transmit electric (magnetic) energy, information and wire products that realize the conversion of electromagnetic energy. In a broad sense, wires and cables are also referred to as cables for short. In a narrow sense, cables refer to insulated cables, which can be defined as: a collection composed of the following parts ; One or more insulated wire cores, and their respective possible covering layers, total protective layer and outer sheath, and the cable may also have additional uninsulated conductors. [0003] UHV transmission line drainage conductors, in order to meet market demand, are generally optimized in terms of how to better conduct electricity and how to make it more convenient for users to use, often ignoring whether it can be...
