Abstract
The utility model relates to an ultrahigh voltage overhead wire suitable for high-voltage overhead use of 330kV and above in power transmission. The technical scheme includes that two aluminum wire layers in sparse arrangement are uniformly and sequentially arranged outside a steel strand in the center of the wire in a stranded manner, and two aluminum wire layers in dense arrangement are uniformly and sequentially arranged outside the aluminum wire layers in sparse arrangement. The outer diameter of the overhead wire is enlarged, and accordingly electric field strength on the surface of the wire is reduced, corona discharge is avoided, and electric energy loss and electromagnetic interference to surrounding environments in power transmission can be reduced. Weight of the wire of a unit length is lighter, and the ultrahigh voltage overhead wire is convenient in construction and wide in application range. Implement of the ultrahigh voltage overhead wire has remarkable economic benefits and social benefits.
Description
Technical field the utility model relates in the electric power transfer, is fit to a kind of superhigh pressure aerial condutor that the above high voltage overhead of 330kV is used.
What the transmission of the present remote power of background technology was adopted usually is steel reinforced aluminium conductor, and its structure is that central core is steel strand wire, in steel strand wire outside stranded the compact arranged aluminum steel of multilayer is arranged.This arrangement mode belongs to regular stranded arrangement architecture, and its advantage is that conductor structure is tight, stable, external diameter is little, but this lead only is suitable for 220kV and following electric pressure circuit.Along with the electric power transfer electric pressure is increasingly high; China's highest voltage level has reached 1000kV; The steel reinforced aluminium conductor of traditional structure is inapplicable, and this is because traditional steel reinforced aluminium conductor external diameter is little, causes conductive line surfaces electric field strength high; Very easily produce corona discharge, the high more corona discharge of electric pressure is serious more.The harm of corona discharge mainly contains two: the one, and electric energy loss increases, and the 2nd, the electromagnetic wave that corona discharge produces has electromagnetic interference to surrounding environment, and this is a problem that can not be ignored.Propose to improve the structure of existing aluminium steel conductor for this reason, satisfy the built on stilts demand of superhigh pressure, it is very necessary improving the electric power transfer quality.
Summary of the invention is in order to satisfy the increasingly high demand of electric power transfer electric pressure; The external diameter that overcomes the conventional steel core aluminum stranded wire is little; Cause conductive line surfaces electric field strength high; Be prone to produce the corona discharge phenomenon, the utility model improves the structure of steel reinforced aluminium conductor, and a kind of superhigh pressure aerial condutor is provided.The technical scheme of the utility model superhigh pressure aerial condutor is: the even stranded aluminum steel layer that two-layer sparse arrangement is arranged successively outside the steel strand wire at lead center, stranded successively outside the aluminum steel layer of sparse arrangement have a two-layer compact arranged aluminum steel layer.The structure of the utility model superhigh pressure aerial condutor; Enlarged the external diameter of aerial condutor; Thereby reduced conductive line surfaces electric field strength, avoided corona discharge, reduced in the electric power transfer electric energy loss and to the Electromagnetic Interference of surrounding environment; And the weight of unit length lead is lighter, easy construction.The enforcement of this lead has remarkable economic efficiency and social benefit.
Appended drawings, be the structural representation of the utility model superhigh pressure aerial condutor.
Embodiment has further understanding for the structure to the utility model superhigh pressure aerial condutor; Following in conjunction with detailed description of the drawings: the structure with reference to accompanying drawing, this superhigh pressure aerial condutor is; Be the external diameter of expansion lead, the even successively stranded aluminum steel layer 2,3 that two-layer sparse arrangement is arranged outside the steel strand wire 1 of lead center tension effect, every layer is evenly equipped with four aluminum steels at least in aluminum steel layer 2,3; To keep the stable of structure, the aluminum steel direction of lay of two interlayers is opposite.Also stranded successively in the outside of aluminum steel layer 3 have a two-layer tight arrangement; The aluminum steel layer 4,5 that direction of lay is opposite, purpose are in order to guarantee the due specification of lead, also are for conductive line surfaces electric field strength uniformity; Prevent to produce electric field distortion, avoid producing corona discharge.
