Abstract
The utility model relates to a kind of antifreeze anti-breaking power transmission line, comprise plain conductor, a plurality of pilot wires, heat-insulation layer and insulating barrier, a plurality of pilot wires are evenly distributed in plain conductor surrounding, and be circle-shaped arrangement, between pilot wire and adjacent pilot wire, along wire direction, be provided with the oblique wire of multilayer, between pilot wire and adjacent pilot wire, by described oblique wire, be connected, oblique wire in same layer is W shape and distributes, and tiltedly the angle between wire and pilot wire is 30 °～60 °, heat-insulation layer is wrapped in the skin of the circumference that a plurality of pilot wires form, insulating barrier is wrapped in the skin of heat-insulation layer.By heat-insulation layer is set, anti-freezing property promotes greatly, by pilot wire and oblique wire are set, plain conductor or the fracture of certain pilot wire, due to the connection function of oblique wire, still make whole circuit keep "on" position, the phenomenon that can not produce power-off occurs, and there is angle between oblique wire and pilot wire, be convenient to the flexible of whole electric wire.
Description
Technical field
The utility model relates to power grid transmission line field, relates in particular to a kind of antifreeze anti-breaking power transmission line.
Background technology
In prior art, power grid transmission line is when cold use in winter, after particularly using for a long time under cold environment, due to the electric wire in freezing state, inner plain conductor is very crisp, in the situation that wind swings, be easy to cause plain conductor fracture, thereby make the power-off of whole piece circuit, need a large amount of time of artificial cost to remove inspection and maintenance, waste time and energy.
Utility model content
In view of this, be necessary to provide a kind of antifreeze anti-breaking power transmission line.
The utility model is to realize like this, a kind of antifreeze anti-breaking power transmission line, comprise plain conductor, a plurality of pilot wires, heat-insulation layer and insulating barrier, described a plurality of pilot wire is evenly distributed in plain conductor surrounding, and be circle-shaped arrangement, between described pilot wire and adjacent pilot wire, along wire direction, be provided with the oblique wire of multilayer, between pilot wire and adjacent pilot wire, by described oblique wire, be connected, oblique wire in same layer is W shape and distributes, and tiltedly the angle between wire and pilot wire is 30 °～60 °, described heat-insulation layer is wrapped in the skin of the circumference that a plurality of pilot wires form, described insulating barrier is wrapped in the skin of heat-insulation layer.
Further, described plain conductor surrounding is evenly distributed with 4 pilot wires.
A kind of antifreeze anti-breaking power transmission line that the utility model provides, simple in structure, by heat-insulation layer is set, anti-freezing property promotes greatly, by pilot wire and oblique wire are set, when cold winter, metal wire is when freezing become very crisp, and plain conductor or the fracture of certain pilot wire, due to the oblique connection function of wire, still make whole circuit keep "on" position, the phenomenon that can not produce power-off occurs, and has angle between oblique wire and pilot wire, is convenient to the flexible of whole electric wire, and can not disconnect, practical reliable.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of antifreeze anti-breaking power transmission line of the utility model;
Fig. 2 is pilot wire in Fig. 1 and the oblique deployed configuration schematic diagram of wire.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
See also Fig. 1 and Fig. 2, wherein Fig. 1 is the structural representation of a kind of antifreeze anti-breaking power transmission line of the utility model; Fig. 2 is pilot wire in Fig. 1 and the oblique deployed configuration schematic diagram of wire.
Described a kind of antifreeze anti-breaking power transmission line, comprise plain conductor 10, a plurality of pilot wires 20, heat-insulation layer 30 and insulating barrier 40, described a plurality of pilot wire 20 is evenly distributed in plain conductor 10 surroundings, and be circle-shaped arrangement, between described pilot wire 20 and adjacent pilot wire 20, along wire direction, be provided with the oblique wire 21 of multilayer, between pilot wire 20 and adjacent pilot wire 20, by described oblique wire 21, be connected, oblique wire 21 in same layer is W shape and distributes, and tiltedly the angle between wire 21 and pilot wire 20 is 30 °～60 °, described heat-insulation layer 30 is wrapped in the skin of the circumference that a plurality of pilot wires 20 form, described insulating barrier 40 is wrapped in the skin of heat-insulation layer 30.
Described plain conductor 10 surroundings are evenly distributed with 4 pilot wires 20.
A kind of antifreeze anti-breaking power transmission line that the utility model provides, simple in structure, by heat-insulation layer 30 is set, anti-freezing property promotes greatly, by pilot wire 20 and oblique wire 21 are set, when cold winter, metal wire is when freezing become very crisp, and plain conductor 10 or 20 fractures of certain pilot wire, due to the oblique connection function of wire 21, still make whole circuit keep "on" position, the phenomenon that can not produce power-off occurs, and has angle between oblique wire 21 and pilot wire 20, is convenient to the flexible of whole electric wire, and can not disconnect, practical reliable.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection range of the present utility model.
