Description
Technical field
A kind of special optical cable of the utility model and power communication system, particularly a kind of Optical Fiber composite overhead Ground Wire that is applied to power distribution network.
Background technology
China extensively adopts OPGW, ADSS to communicate at 110kV～500kV circuit backbone network at present, and the following high-voltage fence of 110kV, low and medium voltage distribution network mainly adopt the communication modes such as ADSS, ordinary optical cable, carrier wave.But be difficult to select the circuit of OPGW, ADSS optical cable for some, OPPC has just demonstrated its distinctive advantage, as:
1) the mesolow transmission lines itself such as 10kV, 35kV, 66kV without ground wire, can't set up OPGW;
2) set up ADSS and have the phenomenon that is corroded of the problem such as safe distance and hanging point distance generation over the ground, the restrictions such as shaft tower insufficient strength;
3) adopt ordinary optical cable to have the difficult problem of being stolen and safeguarding, restriction of carrier communication climate, landform etc.Therefore the fiberize communication of these circuits just needs to consider other composite cable, and OPPC is exactly the supplementary of OPGW, ADSS optical cable, adopts OPPC just to become one of method that solves the distribution communication issue.
China's network system generally adopts the stranded plain conductor of metal as power transmission line, and the Optical Fiber composite overhead Ground Wire of in recent years using is also nuditing wire.In order to improve power supply reliability, stability and fail safe, China requires insulating to adopt insulated conductor at the Medial ﹠ Low Voltage Power Network transmission pressure.
China's communication of power system at present at main line and main branch line by setting up OPGW and ADSS has realized fiberize, but for those without ground wire or single ground wire as 10kV, 35kV, the insulated conductor overhead transmission line of low-voltage is difficult to install OPGW and ADSS and realizes that power optical fiber communicates by letter in 66kV etc., at present mainly by adopting carrier wave or setting up common aerial fiber cable and realize communication, but carrier wave and set up ordinary optical cable and have jitter, easily stolen, the defectives such as the low and poor transmission of the speed of transmission, give the communication that solves this class electrical network, automation, scheduling, the problems such as protection have been brought very large restriction.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of Novel optical cable, can take full advantage of the line resource of electric power system self, dual-use function with electric energy transmitting and communication service, its good insulating can be widely used in the Optical Fiber composite overhead Ground Wire in power distribution network simultaneously.
Be achieved through the following technical solutions above-mentioned purpose:
A kind of Optical Fiber composite overhead Ground Wire that is applied to power distribution network, comprise aluminum steel, insulating sleeve, screen, metal tube, aluminium-clad steel wire and optical fiber, some optical fiber are set in described metal tube, the optical fiber composition light unit that described metal tube is inner with it, described smooth unit and some described aluminium-clad steel wire concentric strandings, stranded described aluminum steel outside described aluminium-clad steel wire and light unit, the described screen of described aluminum steel outer cladding, the described insulating sleeve of described screen outer cladding.
Described smooth unit is 1, and described aluminium-clad steel wire is 6.Central authorities arrange an aluminium-clad steel wire, at periphery one week of this aluminium-clad steel wire stranded five aluminium-clad steel wires and 1 light unit.The aluminium-clad steel wire that arranges take central authorities is as axle, stranded described aluminum steel outside described aluminium-clad steel wire and light unit.Described metal tube is stainless steel tube.Described insulating sleeve is the organosilane crosslinked polyethylene sheath.
The beneficial effects of the utility model are: 1, compare traditional bare wire OPPC, the insulating barrier of its coating makes it have good insulation property, from city, upgrade of rural power grids, has good fail safe and economic results in society.2, increased optical fiber communication function, can realize optical communication, the two-layer stratigraphic structure of its use has guaranteed the stability of structure, the reliability of communication.3, realize that energising, communication and insulation function are integrated, step line upkeep administrative expenses.
