Background technology
In ultra-high-tension power transmission line, generally use optical fiber composite overhead ground wire(OPGW)As protection ground wire and optical communication wire Road, basic structure are made of the conductive reinforcer such as aluminum cald steel wire or aluminum-alloy wire, fiber unit, are erected at the top of steel tower End.
Usually in the long-distance transmission line more than 300km, because being limited by fiber optic communication distance, optical fiber letter need to be added Number amplifier, and use low-voltage power supply.And low-voltage power supply is difficult to take from ultra-high-tension power transmission line, need to use nearby its Its low-voltage circuit is powered to the fiber-optic signal amplifier of ultra-high-tension power transmission line.But near many ultra-high-tension power transmission lines, There is no low-voltage power supplies can be used, especially the areas such as desert, ice and snow mountain area.For this purpose, existing high voltage power transmission field is just carried out The research of this respect, adds feed element in OPGW, and using feed element as low-voltage power supply, i.e. feed optical fiber is compound Aerial earth wire(Letter is abbreviated as OPGW(K)).
Feed is by aluminum cald steel wire, stainless steel tube fiber unit and 2 ~ 4 packets with optical fiber composite overhead ground wire common structure Carry out the conductor composition of plastic insulating layer.The insulation performance of this class formation plastic insulating layer at the beginning is relatively good, but insulating layer needs The requirement of induced voltage when meeting circuit power delivery voltage and normal operation is born continuous caused by supply current, induced current Heating, Short-Circuit High Current caused by failure, extreme high voltage caused by being struck by lightning and induction high current, plastics is old after longtime running Change, makes that insulation performance is decreased obviously or plastic insulating layer is breakdown.And after the decline of plastic insulation performance or insulating layer are breakdown, It can not restore and repair its insulation performance, the conductor of plastic insulation is caused to lose the function of low-voltage power supply.
Invention content
The purpose of the utility model is to overcome the deficiencies in the prior art, a kind of mineral insulation feed is provided and is used up Fine composite overhead ground wire can promote the safety and reliability of ultra-high-tension power transmission line system, facilitate connecting, be suitble to push away on a large scale Wide application, becomes a kind of new technical solution that urgent need solves the problems, such as in industry.The technical solution adopted in the utility model is:
A kind of mineral insulation feed optical fiber composite overhead ground wire, including an at least feed element, one or several light Fine unit, more conductive reinforcers;
The feed element includes external shield protection pipe, and an at least inner wire, Yi Jikuang are equipped in external shield protection pipe Object insulator;Spacing distance is equipped between inner wire and between inner wire and external shield protection pipe;In external shield protection pipe All gap filling mineral insulations;
The feed element, fiber unit and conductive reinforcer close-packed arrays are simultaneously twisted together with concentric circular fashion;Institute State feed element, fiber unit is located at center or the internal layer of lay configuration.
Further, two inner wires are equipped in external shield protection pipe;Between two inner wires and inner wire and external screen It covers and keeps uniform spacing distance between protection pipe.
Further, feed element is equipped with two or more;An inner wire is equipped in external shield protection pipe;Inner wire with Uniform spacing distance is kept between external shield protection pipe.
Further, the mineral insulation is not less than 1750 using magnesia or calcined kaolin or muscovite, fusing point ℃。
Further, external shield protection pipe uses stainless steel tube, and the material of stainless steel tube is 304 stainless steels.
Further, the fiber unit includes outer protection tube, includes multifiber, the filling of outer protection tube internal clearance in outer protection tube The filler of solid or mucilage binding.
Further, outer protection tube uses stainless steel tube, and the material of stainless steel tube is 304 stainless steels.
Further, one in the conductive reinforcer, including aluminum cald steel wire or aluminum-alloy wire or zinc-coated wire or aluminium wire Kind or multiple combinations.
Further, inner wire uses copper conductor.
The utility model has the advantage of:Mineral insulation feed optical fiber composite overhead ground wire provided by the utility model, Devise the structure of novel feed optical fiber composite overhead ground wire.On the one hand, copper conductor and mineral insulation packet are carried out stainless In steel pipe, protection pipe internal mineral insulator, and stainless steel tube can shield electric bear when bearing lightning stroke high voltage, Short-Circuit High Current The destructiveness to insulating layer caused by electric load is significantly reduced or eliminated in lotus, thus be substantially reduced or eliminated voltage, electric current with And to the degree of injury of insulating layer when overload breakdown.On the other hand, mineral insulation, such as the fusing point 2800 of magnesia are used DEG C, its stable insulation is used for a long time in not aging, even if bearing between conductor or repeatedly and hitting between conductor and stainless steel tube Wear, mineral insulation only high-temperature fusion and chemical composition still remains unchanged, do not generate conductive carbide yet, there is overload breakdown The function of self restoring insulation performance afterwards.The effect of above-mentioned two aspect, it is all not only to maintain ultra-high-tension power transmission line normal operation Ground wire and optical fiber communication function also effectively improve the safety of feed optical fiber composite overhead ground wire and system and reliable Property, it is suitble to large-scale promotion application, with utility value very high in industry.
