Background technology
Along with the continuous development of electrical power distribution system and perfect, the particularly construction of the electric power city net and the upgrading of rural power grids and substation automation system, the power distribution network circuit constantly increases, and point is many, wide; Rural power grids shaft tower geographical conditions are complicated and changeable, and the security of operation problem of distribution network is obvious day by day.
For guaranteeing that power circuit does not receive superpotential damages such as thunder and lightning; Remove and carry out corresponding direct lightning strike protection and corresponding lightning protection measures; Good grounding system is the direct bleed off passage that distribution system prevents thunder and lightning overcurrent and operation overcurrent, and down conductor is the basic guarantee of equipment safety operation with reliable, the effective connection of earth mat.Down conductor is the coupling part of power equipment and earth mat; In the long-play process of power equipment; The junction might phenomenons such as node corrosion even fracture occur because of factor affecting such as making moist, and causes down conductor and main ground network tie point resistance to increase; Equipment is in operation has hidden danger, can cause the operation of equipment lost territory when serious.
What the down conductor of current power equipment mainly adopted is that the cross section is not more than the metallic conductor that 35 square millimeters zinc-plated twisted wire, zinc-plated band iron or red copper wire etc. have excellent conductive performance, to guarantee lightning overvoltage the good following path of letting out is arranged.Southern area in humidity; The corrosion of down conductor and the oxidation of metal make thermal stability, mechanical strength and the useful life of downlead reduce greatly, and it is extensive, multi-point and wide-ranging that the distribution line shaft tower distributes in more main being problematic in that; Present position landform, humane complex structure; Metal wire such as copper, zinc-plated band iron body is used as valuable secondary recovery metal by some people and is stolen and cut, and brings unsafe factor to system safety, causes the major hidden danger of the person and device security.
Therefore, prior art awaits improving and development.
The utility model content
The purpose of the utility model is to provide a kind of down conductor with anticorrosion and antitheft effect.
The technical scheme of the utility model is following:
A kind of down conductor; Comprise first rubber layer, fire resistance fibre layer, second rubber layer, the 3rd rubber layer; The fire resistance fibre layer is arranged between first rubber layer and second rubber layer, and the 3rd rubber layer is arranged on second rubber layer, and first rubber layer and second rubber layer are flat shape; The 3rd rubber layer is made up of the square rubber strip of a plurality of cross arrangements anyhow, nano-sized carbon steel core of each square rubber strip parcel.
Described down conductor, wherein, the length of side of each square rubber strip is 0.5cm, highly is 0.8cm.
Described down conductor, wherein, the spacing of the square rubber strip of horizontal each is 0.3cm, the spacing of the square rubber strip of vertical each is 10cm.
The beneficial effect of the utility model is:
The down conductor of the utility model has excellent conducting performance, anticorrosion, antioxidation ability, the ability with good thermal stability and anti-mechanical damage, long service life, the most important thing is to have good antitheft effect; Safety, reliability is high, environmentally friendly, installation and maintenance are easy, with low cost.

Embodiment
The utility model provides a kind of down conductor, for purpose, technical scheme and the effect that makes the utility model is clearer, clear and definite, below with reference to accompanying drawing and give an actual example to the utility model further explain.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
The down conductor of the utility model comprises first rubber layer 10, fire resistance fibre layer 11, second rubber layer 20, the 3rd rubber layer.Fire resistance fibre layer 11 is arranged between first rubber layer 10 and second rubber layer 20; The 3rd rubber layer is arranged on second rubber layer 20; First rubber layer 10 and second rubber layer 20 are flat shape; The 3rd rubber layer is made up of the square rubber strip 30 of a plurality of cross arrangements anyhow, nano-sized carbon steel core 12 of each square rubber strip 30 parcel.
Can know that by Fig. 2 and Fig. 3 the length of side of each square rubber strip 30 is 0.5cm, highly be 0.8cm.The spacing of each horizontal square rubber strip 30 is 0.3cm, and the spacing of the square rubber strip 30 of vertical each is 10cm.
The utility model adopts rubber as basic material; Add toughness fire resistance fibre material; Survey conductor nano-sized carbon steel core 12 (zinc-plated, lead plating) in elastomeric material according to specific netted edge, the favorable conductive of nano-sized carbon steel core 12 and the good toughness and the insulation property of oxidation resistance and elastomeric material are perfectly combined.
Rubber can use waste materials such as reclaiming tire to make just as basic material, reduces product cost greatly.Elastomeric material does not obviously possess the value of secondary recovery compared to precious metal materials such as copper materials, can stop downlead large tracts of land antitheft phenomenon basically from the source, and steal phenomenon is obviously reduced, and guarantees the circuit reliable ground, guarantees system's security of operation and personal security.
Elastomeric material is natural good insulating material, and anti-oxidant ability is strong, and is corrosion-resistant, and useful life is more than 20 years.Interlayer increases the toughness and the survivability of present technique for adding fire proofing such as asbestos fibre.Add surface pattern, present technique is also had improve the anti-skidding effect of cement shaft tower, be convenient to shaft tower maintenance and operation safety as tire.
Nano-sized carbon steel core 12 has excellent conductive performance and oxidation resistance, and is corrosion-resistant, and the toughness of steel core can be satisfied the demand fully.The steel core that disperses has good shunting action with the network structure of laterally establishment, satisfies the needs of through-current capacity fully, and the specification of steel core can be confirmed according to the systematic protection grade.The economy of material is compared to copper material and the cheaper material benefit of zinc-coated flat steel sheet price, and secondary recovery is worth not high.
The down conductor of the utility model has excellent conducting performance, anticorrosion, antioxidation ability, the ability with good thermal stability and anti-mechanical damage, long service life, the most important thing is to have good antitheft effect; Safety, reliability is high, environmentally friendly, installation and maintenance are easy (need not weld during installation, transfer to heart yearn, carry out the line ball connection with copper lug; Very convenient reliable; Practice thrift construction cost, be convenient to field work), with low cost.Be applicable to the down conductor under outdoor environments such as electric force pole tower, telecomm base station.This product is the comprehensive innovation of down conductor product technology, has good practical value and promotion prospect.
Because the toughness and its specific structure of the utility model, the utility model can also change as lead circle type bag, is convenient to carrying and transportation.
Should be understood that, concerning those of ordinary skills, can improve or conversion, and all these improvement and conversion all should belong to the protection range of the utility model accompanying claims according to above-mentioned explanation.
