Description
Technical field
The utility model relates to a kind of electric armour clamp, relates in particular to the employed shading ring connector of all pressing of a kind of overhead power line insulator string and alternating current.
Background technology
At present, the project of transmitting and converting electricity of China is generally plains region or low altitude area, along with expanding economy, in more western high altitude localitiess, will build a large amount of different electric pressure projects of transmitting and converting electricity.Because height above sea level is high more; Air is thin more; The bloom discharge voltage is low more, so the supporting electric armour clamp in high altitude localities is high to anticorona performance requirement, and the project of transmitting and converting electricity of traditional plains region can not satisfy the anticorona requirement of high height above sea level with electric armour clamp on anticorona performance.
Along with the development of 500KV circuit and the use of synthetic insulator, shading ring is all pressed in a large amount of uses in the line project.All press shading ring two ring body ends because certain distance is arranged, for the conductor of high-pressure side, when rough or when the protrusion position is arranged, as easy as rolling off a log generation corona, the generation of this corona not only can produce interference near communications facility, influences communication quality; More disadvantageous is to cause corona loss, will be multiplied when especially rain, snow, greasy weather corona loss are than fair weather, causes the significant wastage of electric energy.
Therefore, we press for a kind of device and solve the corona that rises of under high height above sea level situation, all pressing shading ring, to guarantee the communication quality of communications facility, reduce the loss of corona to electric energy, the conservation of power energy.
The utility model content
The utility model technical problem to be solved provides a kind of all pressures shading ring connector simple in structure, easy to use, and this connector can prevent the generation of corona.
The technical scheme that the utility model adopted is: a kind of shading ring connector of all pressing; Include first cutting ferrule and second cutting ferrule that connect through screw rod, be provided with at the two ends of first cutting ferrule and/or second cutting ferrule and the suitable draw-in groove of fixedly weldering plate of all pressing the shading ring end.
Press such scheme, described first cutting ferrule and second cutting ferrule are the semielliptical type.
Press such scheme, described first cutting ferrule and second cutting ferrule are hemisphere.
Press such scheme, be provided with cavity in described first cutting ferrule and second cutting ferrule.
Press such scheme, be provided with convexity, be provided with and protruding suitable groove in the edge of second cutting ferrule and/or first cutting ferrule in the edge of first cutting ferrule and/or second cutting ferrule.
Press such scheme, on first cutting ferrule and second cutting ferrule, be provided with counterbore.
Press such scheme; Describedly all press the shading ring connector to adopt the ZL102 aluminium alloy to be raw material, to add strontium, silicon, manganese, magnesium and rare earth fusion under hot conditions, adopt the gravity-assist pouring technological forming after; Through solid molten, timeliness heat treatment, the surface is handled through polishing, shot-peening and chemical passivation and is formed.
All press the profile of shading ring connector to form integral body by first cutting ferrule and second cutting ferrule and be elliposoidal or spheroidal structure, inside is hollow-core construction, when improving anticorona performance, further reduces weight, practices thrift cost.Be provided with draw-in groove at first cutting ferrule and/or the second cutting ferrule two ends, be used for cooperating, prevent all to press shading ring dislocation, loosening with the fixedly weldering plate location of all pressing the shading ring end.The counterbore of certain depth is set on first cutting ferrule and second cutting ferrule, when being used for the installation of screw rod accessory, can makes screw head or nut not exceed the elliposoidal outer surface of connector, avoid the generation of this position corona.Edge's house at first cutting ferrule and/or second cutting ferrule has convexity or groove, and during installation, convexity matches with groove, has both reached the effect of mutual location, reaches again fit clearance is reduced to minimum, and further the generation of shading ring connector corona is all pressed in reduction.
It is raw material that the utility model all presses the shading ring connector to adopt with special ZL102 aluminium alloy; Add the fusion under certain hot conditions of trace elements such as strontium, silicon, manganese, magnesium and rare earth; After adopting the gravity-assist pouring technological forming; Through solid molten, timeliness heat treatment, the surface forms through processing such as polishing, shot-peening and chemical passivations again, satisfies and all presses the high strength of shading ring connector, corrosion-resistant and anticorona performance.
The utility model is applicable in the project of transmitting and converting electricity in high hypo area, and is simple in structure, attractive in appearance, easy to install, can effectively prevent all to press shading ring to play corona, guarantees the communication quality of communications facility, reduces the loss of corona to electric energy, the conservation of power energy.
