Description
Technical field
The utility model relates to a kind of two division steel reinforced aluminium conductor compression type strain clamp, belongs to transmission line technical field of safety protection equipment.
Background technology
In electric power system, ultra-high-tension power transmission line is sustainer and the backbone of electrical network, and therefore, the stable operation of ultra-high-tension power transmission line seems particularly important.In order to improve the conveying capacity of transmission line, reducing corona loss and line reactance, usually in 220kV transmission line, adopting double bundle conductor.Strain clamp is used for wire or lightning conducter to be fixed on the strain insulator string of non-rectilinear shaft tower, plays anchorage effect, is also used for fixing the bracing wire of bracing wire shaft tower.Traditional compression type strain clamp is made up of aluminum pipe and steel anchor, when this traditional compression type strain clamp is applied to double bundle conductor, when there is loose contact in a certain sub-conductor conduction wire clamp of transmission line, two sub-conductor strain clamps will be caused to produce electrical potential difference with being connected between gold utensil tie point, due to connect gold utensil with between strain insulator conduction wire clamp for metal is connected, therefore, the connection gold utensil of original not loaded current is by loaded current, cause connection gold utensil overheated, cause the scaling loss and electric energy loss that connect gold utensil, transmission line can be caused time serious to fall string, safety and stability and the economical operation of ultra-high-tension power transmission line in serious threat.At present, Jiangxi Province Power Network just there occurs the fault that a lot of double bundle conductor connects the mistake cause thermal damage of gold utensil.Therefore, be necessary to improve for traditional two division steel reinforced aluminium conductor compression type strain clamps, prevent electric current from flowing through connection gold utensil, to improve safety and stability and the economical operation of ultra-high-tension power transmission line.
Summary of the invention
The purpose of this utility model is to effectively prevent ultra-high-tension power transmission line to occur to connect gold utensil overheating fault, reduce the loss of ultra-high-tension power transmission line, ensure transmission line safety and stability and economical operation, the open a kind of two division steel reinforced aluminium conductor compression type strain clamp of the utility model.
Realizing the technical scheme that the utility model adopts is: the utility model two division steel reinforced aluminium conductor compression type strain clamp is made up of aluminum pipe, steel anchor and rubber-covered parts; Aluminum pipe is formed by straight tube bending, and at sweep, aluminum pipe straight hole is through bending tube wall in the horizontal direction; The horizontal component of aluminum pipe is inserted from the through hole level of aluminum tube bending end in steel anchor one end, continues and the steel core of anchoring steel reinforced aluminium conductor; Steel anchor other end elliptical ring parcel rubber insulation.Another part of aluminum tube bending is bolted wire drainage thread.
Described steel anchor one end is cylindrical, and one end is elliptical ring; Cylindrical one end is used for continuing and the steel core of anchoring steel reinforced aluminium conductor, on cover aluminum pipe horizontal segment after, adopt the mode aluminum pipe of hydraulic pressure to produce plastic deformation, thus make aluminum pipe, steel anchor and steel reinforced aluminium conductor in conjunction with as a whole; Steel anchor elliptical ring one end is used for being connected with gold utensil, the electro-insulating rubber of high strength is adopted to be wound around, adopt insulating tape that electro-insulating rubber parts are fixed afterwards, electro-insulating rubber adhering components place is positioned at outside steel anchor elliptical ring, steel anchor elliptical ring outer surface is insulated, when be connected gold utensil connect time, its contact-making surface is positioned on rubber-covered face.
Operation principle of the present utility model is, by the steel anchor elliptical ring contacted with connection gold utensil is carried out insulation processing, thoroughly cuts off the possibility connecting gold utensil loaded current, effectively prevents to connect the overheated phenomenon of gold utensil.
The beneficial effects of the utility model are, the utility model, by carrying out insulation processing to steel anchor elliptical ring, thoroughly can cut off the possibility connecting gold utensil loaded current, and effectively prevention connects the overheated phenomenon of gold utensil; The utility model is simply applicable, Be very effective.
The utility model strain clamp is applicable to two division steel reinforced aluminium conductor.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Picture in picture number: 1 is rubber-covered parts; 2 is steel anchors; 3 is aluminum pipes; 4 is bolts; 5 is steel reinforced aluminium conductors; 6 is steel cores; 7 steel anchor elliptical rings.
Embodiment
Below in conjunction with implementing and contrasting accompanying drawing, the utility model is described in detail.
As shown in Figure 1, be two division steel reinforced aluminium conductor compression type strain clamp structural representation.The present embodiment two division steel reinforced aluminium conductor compression type strain clamp is made up of aluminum pipe 3, steel anchor 2 and rubber-covered parts 1.
Aluminum pipe 3 is formed by straight tube bending, and at sweep, aluminum pipe straight hole is through bending tube wall in the horizontal direction; The horizontal component of aluminum pipe 3 is inserted from the through hole level of aluminum tube bending end in steel anchor 2 one end, continues and the steel core 6 of anchoring steel reinforced aluminium conductor 5; Steel anchor other end elliptical ring 7 wraps up rubber insulation.Another part of aluminum tube bending connects wire drainage thread by bolt 4.
Steel anchor 2 is used for continuing and the steel core 6 of anchoring steel reinforced aluminium conductor 5, then aluminum pipe 3 horizontal segment is put, the mode of hydraulic pressure is adopted to make aluminum pipe produce plastic deformation, thus make aluminum pipe, steel anchor and steel reinforced aluminium conductor in conjunction with as a whole, the electro-insulating rubber 1 of high strength is adopted to be wound around steel anchor 2 elliptical ring again, adopt insulating tape that electro-insulating rubber parts are fixed afterwards, electro-insulating rubber parts 1 abutting edge is positioned at outside steel anchor 2 elliptical ring 7, steel anchor elliptical ring 7 outer surface is insulated, when be connected gold utensil connect time, its contact-making surface is positioned on rubber-covered face.Therefore when loose contact appears in a certain sub-conductor wire clamp, because strain clamp being insulate with being connected between gold utensil, therefore there will not be the phenomenon connecting gold utensil shunting and cross cause thermal damage, transmission line safety and stability and economic operation level will be improved.
