Description
Technical field
The utility model belongs to electric power facility field, relates in particular to a kind of terminal tower that can be used as, and meets the single loop difference tower of the requirement of difference Zhi Jin electric substation.
Background technology
Cable shoe support is installing cables terminals, the support platform of arrester, then trolley line and cable are linked together, mainly contain at present two kinds of forms: a kind of is cable terminal station, need to be at ground design framework, also need to consider other facilities such as Work place of operation maintenance personnel, also need expropriation of land etc. simultaneously, another kind is cable termination tower, cable termination tower is that trolley line and cable shoe support are integrated, cable shoe support is arranged on terminal tower, cable terminal, the equipment such as sitting type arrester are arranged on cable termination tower, electrical arrangement is arranged according to the safe distance of outside transformer substation power distribution equipment.By the insulating supporting mode that goes between, cable and trolley line are linked together again.
Cable shoe support is not very common for single loop difference tower in line design at present, and comparatively speaking, hanging wire is cumbersome for single loop difference tower.When difference tower is as line terminal in addition, often occur that main line wire and difference line conductor spacing do not meet safety requirements problem.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of single loop difference tower that difference Zhi Jin electric substation, main line wire and difference line conductor spacing meet safety requirements that meets.
The utility model is to realize like this, a kind of single loop difference tower, this difference tower comprises tower body, in a side of tower body according to equidistantly setting gradually the first half cross-arms from top to the order of bottom, the second half cross-arms, the 3 half cross-arm, the first half cross-arms, the second half cross-arms, the identical mounting base that comprises of the 3 half cross-arm structure, fix with mounting base, and for hanging the conical cross arm main body of wire, it is identical with the tower body cross sectional dimensions of institute installation site that described mounting base is quadra, described cross-arm main body is isosceles triangle, cross-arm main body is fixed by base and the mounting base of isosceles triangle, on the cone angle top of cross-arm main body, be fixedly connected with the transverse slat parallel with cross-arm main body isosceles triangle base, at the two ends of transverse slat, installing hole is set as hanging point.
Further, another side at described tower body equidistantly sets gradually the 4 half cross-arm, the 5 half cross-arm, the 6 half cross-arm according to the order from top to bottom, the 4 half cross-arm is arranged on the position between the first half cross-arms and the second half cross-arms, the 5 half cross-arm is arranged on the position between the second half cross-arms and the 3 half cross-arm, between the 4 half cross-arm and the 5 half cross-arm and between the 5 half cross-arm and the 6 half cross-arm, suspension type lightning rod is set respectively.
Further, at the two ends of the transverse slat of the first half cross-arms, the second half cross-arms and the 3 half cross-arm, connect respectively main line, on the cone angle of cross-arm main body, connect diverging tracks.
Compared with prior art, beneficial effect is the utility model:
The utility model structure meets the requirement of difference Zhi Jin electric substation, can also meet terminal difference tower the lightning-arrest requirement arranging is set, and the asymmetric setting in tower body both sides in addition, improves the safe distance between circuit.
The utility model structure can reduce consumption, reduction tower height, the structure design advantages of simple, safe and reliable to operation of tower material in addition; effectively reduce construction costs; both realized the demand of single loop difference tower, and can meet again terminal tower and hang the lightning-arrest requirement that waits protection equipment.
The structure of half cross-arm of the utility model difference tower can not increase string length can not affect scissors crossing, can not cause the problem that wire and steel tower safe distance are inadequate yet.
Accompanying drawing explanation
Fig. 1 is the device structure schematic diagram that the utility model embodiment provides;
Fig. 2 is the structural representation of half cross-arm that provides of the utility model embodiment.
The specific 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.
As shown in Figure 1-2, a kind of single loop difference tower, this difference tower comprises tower body 1, in a side of tower body 1 according to equidistantly setting gradually the first half cross-arms 2 from top to the order of bottom, the second half cross-arms 3, the 3 half cross-arm 4, the first half cross-arms 2, the second half cross-arms 3, the identical mounting base 9 that comprises of the 3 half cross-arm 4 structures, fixing with mounting base 9, and for hanging the conical cross arm main body 12 of wire, it is identical with the tower body cross sectional dimensions of institute installation site that mounting base 9 is quadra, cross-arm main body 12 is isosceles triangle, cross-arm main body 12 is fixing by base and the mounting base 9 of isosceles triangle, on cone angle 10 tops of cross-arm main body 12, be fixedly connected with the transverse slat 11 (see Fig. 2) parallel with cross-arm main body isosceles triangle base, at the two ends of transverse slat 11, installing hole 13 is set as hanging point.
