Description
Technical field
The present invention relates to a kind of expanding connecting line, particularly relate to the expanding connecting line of a kind of outdoor extra-high voltage experiment.
Background technology
On extra-high voltage GIS (gas insulated combined electrical equipment) test platform, need the frequent change mode of connection to obtaining different tests data.Because electric pressure is higher, require higher to pass through electric current, the corona noise etc. of connecting line.When adopting engineering with hard wire, it is well positioned to meet through-current capability and comparatively low noise level requirement, such as adopt the supporting conductor spacer of 4 division JLHN58K-1600 wire of engineering reality, but its weight is very big, general reconfiguration line needs crane and several personnel to match just to complete, if need frequent reconfiguration line, needs at substantial manpower and materials.Masking foil Telescopic corrugated pipe is selected in another measure, its weight is little, the requirement of corona noise can be met by different-diameter customized, the such as patent No. is the Chinese utility model patent of a CN99225495.7 Telescopic corrugated pipe, this bellows is upper oblique line Duan Bobi by cross section, declivity line segment ripple wall and connect on, the garden arc crest of declivity line segment ripple wall and upper, the triangle trough that declivity line segment ripple wall self is formed is formed, but its due to lifting surface area larger, in the high-altitude of ultra high voltage grade, easily occur damaged under the weather such as strong wind heavy rain, reliability is lower.
Summary of the invention
For the deficiencies in the prior art, the invention provides that a kind of replacement cost is low, noise level is low, can Long-Time Service, the expanding connecting line of outdoor extra-high voltage experiment that reliability is higher.
Concrete scheme of the present invention is: the expanding connecting line of a kind of outdoor extra-high voltage experiment, comprise conductor spacer, stressed wire line, conductive braided fabric line and stopping means, described conductor spacer is circular, on the surface of described conductor spacer, the center of circle around conductor spacer is alternate is provided with the first through hole and the second through hole, the aperture of described first through hole is greater than the aperture of described second through hole, described stressed wire line is through the second through hole, and it is stressed with the contact internal walls of described second through hole, described conductive braided fabric line is through the first through hole, described stopping means is fixed on stressed wire line, and be positioned at the both sides of conductor spacer.
Further, described stressed wire line is stainless steel silk thread.
Further, described conductive braided fabric line is copper litzendraht wire.
Further, described conductor spacer is aluminum annulus.
Further, described stopping means is the iron sheet of clamping.
Further, described conductor spacer internal diameter is 40cm, and external diameter is 44cm, and thickness is 3mm.
Further, described conductor spacer surface is respectively equipped with 4 the first through holes and the second through hole.
Further, the aperture of described first through hole is 8mm, and the aperture of described second through hole is 5mm.
Further, the diameter of described stressed wire line is 3mm.
Adopt technique scheme, technique effect of the present invention has:
The present invention is that a kind of weight is little, and processing is simple, and structure is reliable, possess the connecting wire device of tolerance strong wind heavy rain weather, its expanding design produces the phenomenon of corona under can effectively suppressing high voltage, can give full play to safety, flexibly advantage at the trial, reduce experimentation cost, have higher economy.
The present invention adopts aluminium spacers rod to reduce connecting line weight and proof strength, and conductive line surfaces field intensity is reduced, and reduces corona impact; Connecting line selects two kinds of different materials cross arrangements, gives full play to the satisfactory electrical conductivity of the higher tensile strength of steel wire rope and copper material; The relative position fixing means of conductor spacer and wire is simple and easy to safeguard; Integrated connection line apparatus weight is little, singlely can complete connection work.
Accompanying drawing explanation
Fig. 1 is the structural representation of conductor spacer provided by the invention;
Fig. 2 is the structural representation of expanding connecting line provided by the invention;
Fig. 3 is the structural representation of an execution mode of expanding connecting line provided by the invention.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail.
As depicted in figs. 1 and 2, the expanding connecting line of a kind of outdoor extra-high voltage experiment, comprise conductor spacer 1, stressed wire line 2, conductive braided fabric line 3 and stopping means 4, due to the test relevant to test platform, in general normal current is no more than 10A, therefore adopt the hard wire of the large cross section of engineering also unnecessary, cross-sectional area 20mm
2copper cash can meet through-flow demand.When pressing grade to reach 1100kV, use single 20mm
2its surface electric field intensity of copper conductor can exceed discharge inception voltage, can cause larger corona noise on the one hand, can bring the harmful effects such as radio interference on the other hand to other equipment, therefore considers to adopt bundle conductor form to reduce conductive line surfaces field intensity.Conductor spacer 1 needed for bundle conductor is in circular, be preferably aluminum annulus, internal radius is 40cm, external diameter is 44cm, thickness is 3mm, on the surface of conductor spacer 1, the center of circle around conductor spacer 1 is alternate is provided with the first through hole 5 and the second through hole 6, preferred interval is provided with 4 the first through holes 5 and 4 the second through holes 6 uniformly, the aperture of the first through hole 5 is greater than the aperture of the second through hole 6, the aperture of the first through hole 5 is 8mm, the aperture of the second through hole 6 is 5mm, because the tensile strength of copper cash is lower, the stainless steel stressed wire line 2 of diameter 3mm is chosen as main stress point in the present embodiment, it is second through hole 6 of 5mm through diameter on conductor spacer, and it is stressed with the contact internal walls of the second through hole 6, what the relative position between stressed wire line 2 and conductor spacer 1 fixed utilization is the stopping means 4 that intensity is higher, because conductor spacer weight is little, clamping iron sheet fixed intervals rod 1 position directly chosen by stopping means 4.Play first through hole 5 of copper conductive braided fabric line 3 through conductor spacer 1 of electric action.Because copper conductive braided fabric line 3 does not play stressed effect, and for avoid it to damage as far as possible, what it passed is diameter is the hole of 8mm, leaves larger leeway.
As shown in Figure 3, due to stressed wire line 2 and conductive braided fabric line 3 softer, take interval 2.5 meter ampere to put a conductor spacer in the present embodiment, can ensure not easily to be crossed as sub-thread between wire.The connecting line length of the present embodiment is not more than 50 meters.
Finally should be noted that: above embodiment is only in order to illustrate that technical scheme of the present invention is not intended to limit, although with reference to above-described embodiment to invention has been detailed description, those of ordinary skill in the field are to be understood that: still can modify to the specific embodiment of the present invention or equivalent replacement, and not departing from any amendment of spirit and scope of the invention or equivalent replacement, it all should be encompassed in the middle of right of the present invention.
