Description
Technical field
The utility model relates to a kind of overhead transmission line angle tower, in particular, is a kind of horizontal transmission line of electricity single loop angle tower being applicable to heavy icing area.
Background technology
There is one of more country of powerline ice-covering accident in China, icing density serious threat, to the safe operation of China's power system, and causes huge economic loss.Icing density form is varied, and except common iron tower structure destroys, the line tripping caused due to ice-shedding is also one of principal mode of icing density.Tradition heavy icing area dry font angle tower wire is that triangle is arranged, the probability deicing flashover between upper and lower phase conductor is improved greatly.And the horizontal wine glass-shaped angle tower (as Fig. 3) of wire, although its anti-flashover ability is better than dry font tower, its structure of cranking arm is being born under larger uneven ice loading, and displacement is comparatively large, and icing overload capacity is poor, there is structural hidden danger.
Utility model content
The purpose of this utility model is the deficiency overcoming prior art existence, provides one can provide shaft tower anti-icing flashover ability, can ensure again the heavy icing area transmission line of electricity angle tower of shaft tower icing overload capacity.
The purpose of this utility model has been come by following technical solution:
Heavy icing area horizontal transmission line of electricity single loop angle tower, comprise tower head 1, tower body 2, the tower leg 3 from top to bottom arranged, and the composite material support aluminium alloys poling be fixedly connected on tower head, it is characterized in that described tower head is made up of superposed two ground wire upper frames, the wire cross-arm that is positioned at both sides, bottom; The two-phase limit wire of transmission line of electricity is arranged in wire cross-arm two ends, and limit wire wire jumper adopts V-type jumper string to pass through below cross-arm; Middle phase conductor is arranged in tower head center, and middle phase conductor wire jumper is passed in the middle of two ground wire upper frames by composite material support aluminium alloys poling.
Described two-phase limit wire and middle phase conductor are in horizontal.
The beneficial effects of the utility model are: the horizontal transmission line of electricity single loop angle tower provided, and by by three-phase conducting wire horizontal arrangement, can significantly reduce the probability deicing flashover between wire.Meanwhile, owing to there is no the inter-chamber tower window of similar wine glass-shaped tower, its structure feature and dry font tower basically identical, whole tower structure is reasonable, and icing overload capacity is strong, there is not the weak spot that similar wine glass-shaped tap node is such; Effectively can strengthen the anti-ice calamity ability of transmission line of electricity.

Detailed description of the invention
The utility model, from wire arrangements and the rational angle of structure stress, has carried out technical economic analysis to the multiple arrangement of heavy icing area transmission line of electricity angle tower, proposes a kind of horizontally transmission line of electricity single loop angle tower.
Below in conjunction with accompanying drawing illustrated embodiment, the utility model is described in further detail.
As shown in Figure 1, the utility model comprises tower head 1, tower body 2, tower leg 3 and the composite material support aluminium alloys poling 4 (being positioned at the central authorities of two ground wire upper frames 5) that is fixedly connected on tower head from top to bottom arranged.
Described tower head 1 is made up of superposed two ground wire upper frames 5 (ground wire to be fixed on the K point position of ground wire upper frame by insulator), the wire cross-arm 6 that is positioned at both sides, bottom.The two-phase limit wire of transmission line of electricity is arranged in wire cross-arm 6 two ends (as shown in Figure 2: in the wire of every root limit, two wires to be connected are fixed on the G point position of wire cross-arm respectively by insulator), limit wire wire jumper passes through under the support of V-type jumper string 7 below wire cross-arm 6, is connected by two of homophase wires; Middle phase conductor is arranged in tower head center (as shown in Figure 2: in middle phase conductor, two wires to be connected are fixed on the F point position of tower head respectively by insulator), middle phase conductor wire jumper passes from composite material support aluminium alloys poling 4 (this aluminium alloys poling is supported by insulating composite material support 4-1), is connected by two of homophase wires.Whole tower three-phase conducting wire is in horizontal.
