Description
Technical field
The utility model relates to a kind of big current transmission line, is specifically related to the charged downlead component on a kind of big current transmission line.
Background technology
When equipment on transmission line goes wrong and needs maintenance in running, need disconnected branches power supply to guarantee safety inspection.In order to ensure operation of power networks, sometimes need charged deciliter branch road.Above-mentioned two kinds of operations all will use downlead component, but the structure of current downlead component is generally screw rod promotion slide block and moves up and down along the track inside support body, and the rotation of screw rod likely makes slide block also produce certain rotation, stuck phenomenon is there is in the process that so just may move up and down at slide block, assembly and disassembly operations difficulty is large, and staff's operation with high pressure is dangerous; In addition also may not clamping wire and occur arcing, impact power supply.
Utility model content
The purpose of this utility model is the charged downlead component of overhead transmission line big current providing a kind of fast assembling and disassembling convenience, stable mechanical performance, improves Supply Security.
The utility model discloses the charged downlead component of a kind of overhead transmission line big current, comprise branch cable clamp and Wiring nose, branch cable clamp comprises cable inlet bracket and the cover plate of upper and lower docking, removably connects between Wiring nose and the downside of cable inlet bracket.
The cross section interlude of described cover plate and cable inlet bracket is the arc section of evagination, both sides are for connecting wing plate, connect on wing plate and be furnished with butt hole along its length, two arc sections are coated by bus, are connected fastening by the bolt and corresponding nut passing butt hole by cover plate with cable inlet bracket; There is convex along its length in the outside of cable inlet bracket arc section, and on convex, through-thickness is furnished with screw.
Described Wiring nose is the single piece that connecting plate, aluminium hydraulic pressed connecting pipe and guard tube are arranged successively, and connecting plate is L-type plate, and its horizontal segment has connecting hole, and aluminium hydraulic pressed connecting pipe is positioned at the lower end of the vertical section of connecting plate, and guard tube is positioned at the lower end of aluminium hydraulic pressed connecting pipe; Connecting plate is connected fastening by the screw through connecting hole with the screw on the downside of described cable inlet bracket.
Branch cable clamp of the present utility model is circular arc clad type to the split framework of folder bus, cover plate and cable inlet bracket bus is coated after be bolted fastening, the connecting plate of Wiring nose is connected fastening by screw with cable inlet bracket.Crimping conduction in the cable core insertion aluminium hydraulic pressed connecting pipe that offset terminal is exposed, the insulating barrier at insulating stripping mouth place inserts the interior crimping of guard tube and avoids rainwater and dust to enter.
The contact area of branch cable clamp and bus is large, docking between its cover plate and cable inlet bracket is fastening, Wiring nose is fastening with the connection of branch cable clamp, Wiring nose crimps the characteristic all with stable mechanical performance with offset, thus ensures the object realizing raising Supply Security.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is that schematic diagram is looked on the right side of Fig. 1.
Embodiment
As shown in Figure 1 and Figure 2, the utility model discloses the charged downlead component of a kind of overhead transmission line big current, comprise branch cable clamp 1 and Wiring nose 2.
Branch cable clamp 1 is upper and lower Split type structure, comprises the cable inlet bracket 11 and cover plate 12 that cooperatively interact.The cross section interlude of cover plate 12 and cable inlet bracket 11 is the arc section of evagination, both sides are for connecting wing plate, connect on wing plate and be furnished with butt hole along its length, cover plate 12, by coated for bus 3, is connected fastening with cable inlet bracket 11 by the bolt and corresponding nut passing butt hole by two arc sections.There is convex 111 along its length in the outside of cable inlet bracket 11 arc section, and on convex 111, through-thickness is furnished with wiring screw.
The integral part that Wiring nose 2 is connecting plate 21, aluminium hydraulic pressed connecting pipe 22 and guard tube 23 are arranged successively.Connecting plate 21 is L-type plate, and its horizontal segment has connecting hole, and aluminium hydraulic pressed connecting pipe 22 is positioned at the lower end of the vertical section of connecting plate 21, and guard tube 23 is positioned at the lower end of aluminium hydraulic pressed connecting pipe 22.Connecting plate 21 is connected fastening by the screw through connecting hole with the wiring screw on the downside of cable inlet bracket 11.
Branch cable clamp 1 is circular arc clad type to the Split type structure of folder bus 3, and cover plate 12 and cable inlet bracket 11 are fastening by being bolted after coated for bus 3.The connecting plate 21 of Wiring nose 2 is connected fastening by screw with cable inlet bracket 11.Crimping conduction in the cable core insertion aluminium hydraulic pressed connecting pipe 22 that offset 4 terminal is exposed, the insulating barrier at insulating stripping mouth place inserts the interior crimping of guard tube 23 and avoids rainwater and dust to enter.
Branch cable clamp 1 is large with the contact area of bus 3, docking between cover plate 12 and cable inlet bracket 11 is fastening, Wiring nose 2 is fastening with the connection of branch cable clamp 1, Wiring nose 2 crimps the characteristic all with stable mechanical performance with offset 4, thus ensures the object realizing raising Supply Security.
First bus 3 power-off is installed branch cable clamp 1 during use, cable core exposed for offset 4 terminal is inserted crimping in aluminium hydraulic pressed connecting pipe 22, the insulating barrier at insulating stripping mouth place inserts guard tube 23 and crimps.Be energized then to bus 3, use insulating bar to coordinate fastened tools to be connected fastening by Wiring nose 2 with cable inlet bracket 11 by screw.
