Description
Technical field
The utility model patent relates to a kind of joint design of optical cable, is used to connect the fine composite power cable of heterogeneous electric light, is applied to construction, maintenance and the repairing of the fine composite power cable of heterogeneous electric light in the intelligent grid construction.
Background technology
The primary effect of intelligent grid in the construction is effectively to guarantee the electric power safety reliability, makes more traditional electrical network stronger, the influence that can withstand natural calamities effectively, all kinds of accidents such as outside destroy causes to electric system; And have powerful " self-healing " function, and can pass through remote equipment in-service monitoring and system information analysis, predict and dispose the sorts of systems fault more in time, exactly.This just need a kind of can be at high voltage, highfield environment, can online detection power cable running status, technological means that again can high-speed high capacity transmission detection information.
Optical fiber has directly thin, soft, the lightweight mechanical property of matter.Electric property with insulation, electromagnetic-radiation-free.Also has water-fast, high temperature resistant, corrosion resistant chemical property.The light signal that optical fiber transmits has the performance of anti-electromagnetic interference (EMI) and atomic radiation.Can (close) in the area that is pernicious to people with the optical fiber fabrication sensor as nuclear radiation district and strong-electromagnetic field, recipient's sense organ impression less than external information.Simultaneously, optical fiber also can realize at a distance, the information communication of high-speed high capacity.
Therefore the fiber composite power cable that arises at the historic moment can satisfy the needs that intelligent grid is built preferably.But in fiber composite power cable is used, will face the optical cable intermediate head problem of solution in the fine composite power cable of heterogeneous electric light is used.In the communications optical cable intermediate head method of routine, 2 optical cables that need connect all will respectively leave one section surplus length and be used for continuing of optical fiber.Owing to after the footpath is thin, matter multicore bundle fiber optic cable soft, easy to break is embedded in the thick and stiff power cable,, will from each composite cable, strip out the surplus length section of cable connection of certain-length if the optical cable method of attachment connects 2 sections composite cables routinely.To clip 2 single-phase heart yearns of many cables that need the surplus length of the corresponding optical cable in composite power cable end of connection respectively for this reason.So not only cause the waste of precious materials such as copper conductor, and in repairing composite cable joint, the composite cable of breaking-up can't provide also and satisfy the surplus length of the needed cable of cable connection.
Given this, be necessary to propose a kind of new structure and method and be used to improve the problems referred to above.
The utility model content
The technical problems to be solved in the utility model provides a kind of joint design of optical cable, be used to connect the fine composite power cable of heterogeneous electric light, by optical cable coupling arrangement and the corresponding accessory kit that adopts a kind of embedded type, effectively solve the optical cable intermediate head problem of the fine composite power cable of heterogeneous electric light in intelligent grid is applied at present.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: a kind of joint design of optical cable, be used to connect the fine composite power cable of heterogeneous electric light, and the joint design of this optical cable comprises the optical cable coupling arrangement that connects the two ends multifiber cable; The end connector that contains prefabricated fibre bundle and connect this fibre bundle in the described optical cable coupling arrangement.
Preferably, described fiber cable joint structure further comprises the cold/thermal shrinkage type insulating plastic nipple protective casing that wraps up described optical cable coupling arrangement.
Preferably, described fiber cable joint structure further comprises the multi-branched type pyrocondensation fingerstall of the interior single-phase heart yearn of plural cable of the fine composite power cable of the heterogeneous electric light of clamping and many fibre cores optical cable.
Preferably, described end connector is the nonmetal end connector of cold joint type mechanical type.
The utility model effectively solves the optical cable intermediate head problem of the fine composite power cable of using of heterogeneous electric light in intelligent grid is built at present.Can on the basis that keeps original non-compound polyphase electric power cable intermediate joint maturation process, realize effective connection of optical cable in the composite power cable.Solved at present to connecting the optical cable in 2 composite power cables, and need clip the problem of Single Phase Metal heart yearn of big section power cable end.Thereby save a large amount of precious materials such as copper.For the construction of fiber composite power cable and safeguard that repairing provides crucial technical conditions.
