Abstract

The description relates to a power cable with several power cores as a sector conductor and an optical core in an unoccupied sector. The optical core takes the form of a bunched cable of a plurality of stainless steel tubes with optical fibers (LWL tubes). The cable provides an integrated solution for power and data supply for a network. The cable could be used with advantage as a power cable for local systems with an operative voltage of 1 kV. One LWL tube can be fitted per connection. The stranding of the four-sector cable (1) consists of three single-wire sector lines (10, 10', 10") and the optical core (50). The core filling spaces are filled with strands (30, 31) of differing thickness. In an outer filling there is a further tube (42) with two optical fibers. The cores of the concentric conductor are in corrugated array (CW screen). The concentric conductor can be removed in domestic connections without damage and laid aside, thus providing free access to the cable cores.

Description

Izum se odnosi na energetski kabel sa više kabelskih žila i jednom optičkom žilom sa kabelskom ispunom i zajedničkim kabelskim plaštom. Takav kabel opisan je u DE 89 15 240-U1, No, takovi kabeli nisu prikladni sa kućne priključne kabele ili kabele za rasvjetu ceste,, koji se moraju priključiti jedni na druge i preko optičkih vodova, jer je svjetlovod optičke žile gotovo nepristupačan, a prema današnjim potrebama se svakom priključku mora dodijeliti najmanje jedan svjetlovod Sa sve većom rasprostranjenosti digitalnih informacijskih kanala. (TSDN-tehnika) postoji potreba, da se sve veći broj priključnih mjesta digitalno opskrbi. The invention relates to an energy cable with several cable cores and one optical core with cable filling and a common cable jacket. Such a cable is described in DE 89 15 240-U1, However, such cables are not suitable for household connection cables or cables for road lighting, which must be connected to each other and via optical cables, because the fiber optic cable is almost inaccessible, and according to today's needs, at least one optical fiber must be assigned to each connection With the increasing prevalence of digital information channels. (TSDN-technique) there is a need to digitally supply an increasing number of connection points.

Stoga je zadatak izuma da se pronađe energetski kabel, koji je prikladan kao priključni kabel za kuću ili cestovnu rasvjetu, sa kojim je na raspolaganju velik broj svjetlovoda, a koji je usprkos toga kompaktne konstrukcije. Therefore, the task of the invention is to find a power cable, which is suitable as a connecting cable for a house or road lighting, with which a large number of optical fibers are available, and which is nevertheless compact in construction.

Zadatak se rješava obilježjima 1. zahtjeva. Preferirani daljnji oblici nalaze se u podzahtjevima. The task is solved with the characteristics of the 1st requirement. Preferred further forms are found in the subclaims.

Sa kabelom je na odličan način na raspolaganju integrirano rješenje za opskrbu energijom i mrežnim informacijama. Mogao h se dobro koristiti kabel kao energetski kabel za mjesne mreže s 1 kV baterijskim naponom, Po priključnom mjestu mogla bi s standardno predvidjeti jedna cjevčica svjetlovoda. Kao priključna tehnika koristi se tehnika steznog prstena; kod koje se svaki priključak može dospojiti pod naponom, Svjetlovodi 5 upliću prema poznatoj tehnici, a njihovi upleti se stavljaju posebne kolčake. Optička vlakna koja nisu dodijeljena priključnom mjestu, vode se pored priključnih mjesta. With the cable, an integrated solution for supplying energy and network information is available in an excellent way. The cable could well be used as an energy cable for local networks with 1 kV battery voltage. One optical fiber tube could be provided per connection point. The clamping ring technique is used as a connection technique; in which each connection can be connected under voltage, Fiber Optics 5 are interlaced according to a known technique, and their interlacings are fitted with special clips. Optical fibers that are not assigned to a connection point are routed next to the connection points.

Broj cjevčica svjetlovoda može se stupnjevati prema priključenoj snazi. Tako bi se koristio kabel sa 80 kW za 40 priključaka, čiji korisnici trebaju po 2 kW priključne snage. Broj cjevčica svjetlovoda ravna se prema potrebama, koje definira priključno mjesto. Unutrašnji promjer cjevčice svjetlovoda može se birati između 115 mm, tako da je od 2 svjetlovoda po cjevčici na više moguća i može se koristiti velika, širina pojasa svjetlovoda u jednoj cjevčici. The number of fiber optic tubes can be graduated according to the connected power. Thus, a cable with 80 kW would be used for 40 connections, whose users need 2 kW of connection power each. The number of fiber optic tubes is adjusted according to the needs, which defines the connection point. The inner diameter of the fiber optic tube can be chosen between 115 mm, so that from 2 fiber optic cables per tube to more is possible and a large bandwidth of fiber optic cables in one tube can be used.

Promjer kabela uglavnom se sastoji od četiri sektora, no prema slučaju primjene moguć je drugačiji izbor raspodjele. The diameter of the cable mainly consists of four sectors, but depending on the application, a different choice of distribution is possible.

Sve cjevčice moraju biti napravljene iz istog materijala. U obzir dolazi plastika ili metal. U slučaju odabira metala, uglavnom se predviđa, plemeniti čelik. All tubes must be made of the same material. Plastic or metal comes into consideration. In the case of choosing a metal, stainless steel is generally predicted.

Cjevčice su uglavnom. sukane bez udara. To ima prednost, da. se pojedine cjevčice lako mogu odvoditi i izvaditi za priključivanje, Sve cjevčice su različito označene tako da se lako mogu identificirati. Tubes are mostly. spun without impact. It has an advantage, yes. individual tubes can be easily drained and removed for connection. All tubes are marked differently so that they can be easily identified.

Cjevčice su sukane pod zajedničkim plaštom; Može se primjerice koristiti preklopno namotana PETP folija. The tubes are woven under a common mantle; For example, folded PETP film can be used.

Kabelski vodiči koncentričnog vodiča valovito su raspoređeni (CW-zaštita). Koncentrični vodič može se kod priključaka bez oštećenja nadići i staviti na stranu, tako da je pristup kabelskim žilama slobodan. The cable conductors of the concentric conductor are arranged in waves (CW protection). The concentric conductor can be crossed and placed to the side without damaging the connections, so that access to the cable cores is free.

Koncentrični vodič može se prema vrsti korištenja koristiti kao nulti vodič kabela ili kao kabelska zaštita. Depending on the type of use, the concentric conductor can be used as a neutral cable conductor or as cable protection.

U međuprostore kabelske žile stavljaju se ispune. Uglavnom se kao materijal odabire polipropilen. Prema namjeni se jedan od međuprostora može koristiti za dojavnu, žicu ili za cjevčicu svjetlovoda. Dobro bi bilo da se odabere vanjska ispuna, jer se tamo najbolje mogu doseći optička vlakna. Fillings are placed in the interstices of the cable cores. Polypropylene is mainly chosen as the material. Depending on the purpose, one of the intermediate spaces can be used for a signal, a wire or a fiber optic tube. It would be good to choose an external filling, because the optical fibers can be reached there the best.

Izum je pobliže objašnjen pomoću slike. Slika prikazuje presjek kabela sa četiri sektora 1. The invention is explained in more detail by means of a figure. The picture shows a cross-section of a cable with four sectors 1.

Sukani snop sastoji se od tri jedno žičana sektorska vodiča 10. 10', 10’’ i optičke žile 50. Vodiči mogu biti od aluminija, legure aluminija ili od bakra. Optička žila je izvedena, kao snop žila iz mnogo (na slici trideset dvije) cjevčica 41 sa (na slici po dva) svjetlovodima 44. Cjevčice optičke žile omotane su relativno tankim ovojem 40 40, Svjetlovodi su u. cijevi umetnuti na poznati način (sa većom, duljinom). Uložna masa u cijevima, mogla, bi se sastojati iz petrolatne ispune. The twisted bundle consists of three single-wire sector conductors 10. 10', 10'' and an optical fiber 50. The conductors can be made of aluminum, aluminum alloy or copper. The optical fiber is made as a bundle of fibers from many (thirty-two in the picture) tubes 41 with (two in the picture) optical fibers 44. The optical fiber tubes are wrapped with a relatively thin sheath 40 40. The optical fibers are inserted into the tube in a known way (with longer, longer). The investment mass in the pipes could consist of petrolatum filling.

Izolacija 20, 20’, 20’’ vodiča. 10, 10’, 10’’ sastoji se uglavnom od PVC-a ili VPE-a (umreženog polietilena). Međuprostori žila imaju gustu ispunu 30, 31 različitih debljina, U vanjskom međuprostoru nalazi se daljnja cjevčica 42 sa dva svjetlovoda. Insulation of 20, 20', 20'' conductors. 10, 10', 10'' consists mainly of PVC or VPE (cross-linked polyethylene). The interspaces of the vessels have a dense filling 30, 31 of different thicknesses. In the outer interspace there is a further tube 42 with two light guides.

Sukani spoj (10, 10’, 10’’) okružen je sa gumenim, unutarnjim plaštom 6, u koji su umetnuti kabelski vodiči ili bakrena žičana mreža koncentričnog vodiča 1. Kabel ima izvana PVC-plašt. Vanjski plašt može biti proizveden i iz PE. The twisted joint (10, 10', 10'') is surrounded by a rubber, inner sheath 6, into which cable conductors or a copper wire mesh of concentric conductor 1 are inserted. The cable has a PVC sheath on the outside. The outer sheath can also be made of PE.

Na slici prikazani kabel ne odgovara ni jednom VDE- ili DIN-standardu. Prema DIN-VDE-terminologiji odgovara (N) AYCWY 3x185 SM/185 0,6/1kV + 32 LWL, na primjer VDE-tip NYCWY 4x185 SM/95 0,6/1kV. Kao priključni, kabel može se zamisliti kabel kao primjer navedenog tipa NAYCWY 4 x 50 qmm sa samo jednom ili malim brojem cjevčica svjetlovoda (primjerice 2 ili 3 kod kuća sa više stanova), Kod tog tipa bi se potrebni svjetlovodi položili u međuprostor,, kao kod primjera VDE-tipa. NYY-J 4x25 RM 0,6/1Kv. The cable shown in the picture does not correspond to any VDE or DIN standard. According to DIN-VDE-terminology it corresponds to (N) AYCWY 3x185 SM/185 0.6/1kV + 32 LWL, for example VDE-type NYCWY 4x185 SM/95 0.6/1kV. As a connecting cable, one can imagine a cable as an example of the mentioned type NAYCWY 4 x 50 qmm with only one or a small number of optical fiber tubes (for example, 2 or 3 in houses with several apartments). With this type, the necessary optical fibers would be laid in the intermediate space, in the VDE-type example. NYY-J 4x25 RM 0.6/1Kv.
