Abstract
The invention discloses a 3000 mm<2> aluminum core segmental conductor which is a round electrical conductor combined by a group of fan-shaped electrical conducting band blocks with equal section areas; and the center of the round electrical conductor is filled with aluminum twisted wire. The aluminum core segmental conductor with a large section provided by the invention can transmit larger current and has a transmitting capability equal to that of a 1800 mm<2> copper conductor at the same voltage level, thus, the situation that the global copper resource is short can be relieved.
Description
Technical field
The present invention relates to a kind of material of electric energy transmitting, is the 3000mm on a kind of heavy in section 220kV of being applicable to and above superhigh pressure or the ultra high voltage
2Aluminum core segmental conductor.
Background technology
The maximum aluminium core conductor cross section that can produce in the world at present is 2500mm
2Along with the average annual growth of China GDP and the continuous growth of electricity needs; Improving constantly of electric power transfer electric pressure and cross section; " conductor of GB/T 3956-2008 cable ", " GB/Z 18890-2002 rated voltage 220kV (Um=252kV) power cable with cross-linked polyethylene insulation and annex thereof ", " GB/T 22078-2008 rated voltage 500kV (Um=550kV) power cable with cross-linked polyethylene insulation and annex thereof " and " IEC60228:2004; IDT ", the maximum cable cross section 2500mm that stipulates in " IEC62067:2001 ", " IEC62067:2006, MOD " standard
2Conductor can not satisfy the demand of electric power development, 3000mm in the near future
2The demand of heavy in section aluminum core segmental conductor is appeared suddenly, and the research and development new product also is the task of top priority of electric power system manufacturer.
Summary of the invention
Goal of the invention: technical problem to be solved by this invention is the deficiency to prior art, and a kind of aluminum core segmental conductor is provided.
In order to solve the problems of the technologies described above, the invention discloses a kind of 3000mm
2Aluminum core segmental conductor, said cable core cross-section are that the cross section that the fan-shaped conduction strand piece of one group of uiform section area is combined into is 3000mm
2Circular electric conductor, the electric conductor center of said circle is provided with aluminium stranded conductor.
Among the present invention, be provided with the wrinkle insulating paper layer between the fan-shaped conduction strand piece of said each uiform section area.Be provided with the wrinkle insulating paper layer between said fan-shaped conduction strand piece and the said aluminium stranded conductor.Form insulation thus, can overcome the skin effect of electric current.
Among the present invention, the fan-shaped conduction strand piece of said uiform section area is six.Adopt six segmenting structures, the middle circle twisted wire of filling helps the stable of aluminum core segmental conductor.
Among the present invention, said cross section is surrounded with semiconductive nylon belt outward for circular electric conductor.Not only played thus wrapping with but also electric field strength that can homogenizing conductor periphery.
Said semiconductive nylon belt peripheral hardware has polyester layer, shields, and when carrying out next procedure, divests.
Beneficial effect: 3000mm of the present invention
2Bigger electric current can be transmitted in the aluminum core segmental conductor heavy in section, and it is equivalent to 1800mm under identical electric pressure
2The transmittability of copper conductor also can be alleviated the situation of global copper scarcity of resources.
