Abstract
The invention discloses a cross-connect grounding coaxial cable for an extra-high tension cable circuit. The cable comprises inner conductors positioned in the center, wherein inner conductor insulating layers are extruded outside the inner conductors; outer conductors are sparsely lapped outside the inner conductor insulating layers; and outer conductor insulating layers are extruded outside the outer conductors. The original two grounding lines are combined into a whole, so that the probability of error connection is reduced; after the lines are combined, the volume of the cable is reduced; therefore, the cable is simple and convenient to manage and transport, and the cost can be saved.
Description
Technical field
The invention belongs to the power cable field, specifically is the cross interconnected earthy coaxial cable of a kind of extra-high-tension cable circuit.
Background technology
In recent years, China 110KV, 220KV extra-high-tension cable are used in electric power system widely, and the extra-high-tension cable circuit is also more and more longer.Because extra-high-tension cable dead weight, the restriction of production and transportation and length line influence voltage can have the extra-high-tension cable of the use length of placing restrictions on, cable line is for guaranteeing that length also can only adopt insulating joint, simultaneously must adopt ground connection case (or cross interconnected case) in the joint, in order to solve problem with grounding, often at cross interconnected case place adopt two earth connections, be connected with the firm of cable line two ends at the ground connection case in order to guaranteeing.Because long distance line must adopt segmentation to connect, with regard to palpus segmentation ground connection, the more regular meeting of earth connection caused misconnection when wiring when segmentation connected.
Summary of the invention
Technical problem to be solved by this invention provides the cross interconnected earthy coaxial cable of a kind of extra-high-tension cable circuit, and this cable makes the phenomenon that can not occur misconnection ground in the interconnected ground connection process.
The cross interconnected earthy coaxial cable of extra-high-tension cable circuit of the present invention, this cable comprises the inner wire that is positioned at the center, extrudes the inner wire insulating barrier outside inner wire, dredges around outer conductor outside the inner wire insulating barrier, extrudes the outer conductor insulating barrier outside outer conductor.
Above-mentioned outer conductor and inner wire are equal sectional area.
The present invention is merged into one with original two earth connections, has reduced the possibility of misconnection, and merges the back volume-diminished, and is not only succinctly but also be convenient to management and transportation, cost-saved again.
Description of drawings
Fig. 1 is a cross section structure schematic diagram of the present invention.
Embodiment:
As shown in Figure 1, the cross interconnected earthy coaxial cable of extra-high-tension cable circuit of the present invention, comprise the inner wire 1 that is positioned at the center, outside inner wire, extrude inner wire insulating barrier 2, outside inner wire insulating barrier 2, dredge around outer conductor 3, extrude outer conductor insulating barrier 4 at last outside outer conductor 3, wherein outer conductor 3 and inner wire 1 have equal sectional area.
In actual cable line construction process, adopt coaxial cable to connect when connecting earth connection at cross interconnected case place, inner and outer conductor is made when being connected quick and easy on same cable, not only save time but also be difficult for makeing mistakes, thereby effectively improved operating efficiency.
Production technology of the present invention:
The first step: the cross section of determining cross interconnected earth connection according to service cable circuit transmission capacity and the short circuit current that bears;
Second step: it is stranded to begin to carry out inner wire after the cross section is determined, check measurement inner wire cross section;
The 3rd step: inner wire is extruded interior insulation;
The 4th step: determine that with the principle of uiform section outer conductor root and diameter carry out the wrapped of outer conductor according to the external diameter calculating after the insulation in extruding and outer conductor and inner wire;
The 5th step: the sheath of extruded insulation level outside outer conductor.
The invention provides the thinking and the method for the cross interconnected earthy coaxial cable of a kind of extra-high-tension cable circuit; the method and the approach of this technical scheme of specific implementation are a lot; the above only is a preferred implementation of the present invention; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the principle of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.The all available prior art of each component part not clear and definite in the present embodiment is realized.
