Abstract

The utility model relates to an energy-saving extended conducting wire, which belongs to the technical field of power transmission lines. The utility model is characterized in that a conductive part of the conducting wire is made of soft aluminum with high conductive performance to reduce power transmission energy consumption and realize power transmission energy saving. Simultaneously, the forming mode of a power transmission line is unnecessary to change when the power transmission line is extended to transmit power. The conducting wire is composed of the conductive part and a force bearing part which are respectively twisted by taking mutually separate and independent structure; the conductive part is made into a hollow tubular object; the force bearing part is penetrated in the conductive part to form the built-in force bearing type structure. A gap exists between the conductive part and the force bearing part; the conductive part and the force bearing part can relatively and freely expand, contract and slide. When the line is extended to about one time of the same conventional line, the increment of sag of the conducting wire arc is still in the range allowed by the conventional line; therefore, the extension of the line dispenses with rebuilding poles; the conducting wire of the line has latent extended capacity.

Description

Energy-saving capacity expansion conducting wire

Technical field: belonging to the transmission line technical field, exactly is that a kind of to relate in transmission line used lead be by current-carrying part independently and load independently both technology of combining partly.

Background technology: transmission line, generally adopt steel reinforced aluminium conductor or steel core aluminium alloy stranded conductor, wherein steel core is galvanized steel wire or aluminium-clad steel wire, it is as the load part, aluminum steel or aluminium alloy wire are current-carrying part, and it is stranded on the load part tightly, makes hard-packed lead.For increasing the transmission capacity of lead, must strengthen the conductive cross-sectional area of lead or the operating temperature of raising lead, the height that its result then needs to strengthen the intensity of shaft tower or improves shaft tower.Meanwhile, when improving the lead operating temperature, for guaranteeing the security reliability of due intensity of lead and operation, need change into and adopt heat resistant aluminum alloy wire as current-carrying part, with invar, aluminium bag invar or organic synthetic fibers, or carbon fiber line is as the load part.Even so, poorer than electrician's aluminum steel because of the electric conductivity of heat resistant aluminum alloy wire, during operation, the loss of circuit increases; The material of load part costs an arm and a leg again, thus the investment when increasing line construction.

Summary of the invention:

The utility model provides a kind of soft aluminum conductor by high conduction performance to make the lead of current-carrying part, and energy consumption reduces when making transmission of electricity, realizes that transmission of electricity is energy-conservation; Adopt high strength simultaneously, and the less composite twisted wire with galvanized steel wire or steel wire and organic composite fibre of thermal coefficient of expansion is made the load part of lead, the separate retractable activity of current-carrying part and load part also needn't change a kind of energy-saving capacity expansion conducting wire of transmission line structure form when dilatation is transmitted electricity.

Technical solution adopted in the utility model is:

Lead partly is made up of current-carrying part and load, the soft aluminium of taking conductance to be not less than 62.5%IACS is made the current-carrying part of difformity cross section, the conduction single line of shape of the same race, around the center conductive supporting layer, twist together with having levels, the high strength twisted wire that passes the center conductive supporting layer constitutes the load part, and the interior interlayer of its external diameter and center conductive supporting layer has a gap.

The center conductive supporting layer can be that seam or seamless pipe are arranged, and also can be by fan-shaped, zigzag, or the hollow tubular thing of herringbone capitiform.

The varying cross-section shape single line of current-carrying part can be circular, fan-shaped, Z-shaped or herringbone capitiform.

Load part is by the High Strength Steel twisted wire, or the twisted wire made of steel wire and organic composite material.

After implementing the utility model, owing to adopt conductance to be not less than the soft aluminium of 62.5%IACS, energy consumption during transmission of electricity reduces, realized energy-conservation, the pulling force that the weight of its lead is born when setting up is all born by the twisted wire of load part, when the circuit dilatation, even when approximately closely using 1 times of lead capacity always, lead sag increment but still is in the scope that lead commonly used is allowed, and has realized energy-conservation purpose that again can dilatation.
