Connecting tail cable for modular design of power transmission line

Abstract

The invention discloses a connecting tail cable for modular design of a power transmission line, which comprises a power transmission conductive core, wherein an inner protective layer is fixedly connected outside the power transmission conductive core, a protective shell is arranged outside the inner protective layer, limiting assemblies are uniformly and fixedly connected to the outer surface of the inner protective layer, unfolding protection assemblies are symmetrically arranged on the two sides of the bottom end of the exterior of the protective shell, flattening storage frames are symmetrically arranged on the two sides of the exterior of the protective shell, contact bottom plates are slidably connected to the positions, which are located at the bottom of the protective shell, in the flattening storage frames, contact assemblies are evenly arranged on the surfaces of the bottom of the contact bottom plates, and resistance increasing contact pieces are fixedly connected to the left side and the right side of the bottom end of the interior of the limiting inner groove. The invention relates to the technical field of power transmission lines. According to the connecting tail cable for the modular design of the power transmission line, the resistance for resisting torsion is gradually increased, the torsion is relieved, the tail cable is protected from being damaged by the torsion, meanwhile, the displacement of an inner core of the tail cable is reduced, and the stability of the structural state of the inner core of the tail cable is guaranteed.

Description

technical field [0001] The invention relates to the technical field of power transmission lines, in particular to a connecting tail cable for modular design of power transmission lines. Background technique [0002] The transmission line is realized by using a transformer to boost the electric energy generated by the generator, and then connecting it to the transmission line through control equipment such as a circuit breaker. Structural forms, transmission lines are divided into overhead transmission lines and cable lines. [0003] The overhead transmission line is composed of line towers, wires, insulators, line fittings, guy wires, tower foundations, grounding devices, etc., and is erected above the ground. According to the nature of the transmission current, power transmission is divided into AC transmission and DC transmission. [0004] At present, the tail cables of power transmission lines do not have the ability to prevent torsion. When a large torque occurs betwee...

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides a connecting tail cable for modular design of power transmission lines, which solves the problem that the tail cables of current power transmission lines do not have the ability to prevent torsion, and when a large torque occurs between the inner core and the outer protective layer, it can be twisted. damage, thus affecting power transmission, the traditional tail cable is easily damaged by sharp objects during the dragging process, and the dragging process is likely to cause the tail cable to flip, increasing the torsional force of the tail cable transmission
