Abstract
The utility model belongs to the field of 10kV distribution overhead lines, and more specifically relates to a compact insulation support. The compact insulation support, comprising cross arms fixed to a rod tower, is characterized in that each cross arm at each side of the rod tower is equipped with three overhead insulation wire hanging points that are arranged in a horizontal manner, and three-insulation wires of each overhead line are respectively fixed to the three overhead insulation wire hanging points. The compact insulation support is ingenious and reasonable in structural design. Through application of the support, the three-phase insulation wires A, B and C of each overhead line can be arranged horizontally on the rod tower, so that the vertical space is less occupied, the height of the rod tower (especially a steel pipe rod) is reduced, a lot of steel is saved, the construction cost is lowered, and economical effects are greatly improved. Meanwhile, it becomes more feasible that multiple 10kV overhead lines stretch across 35kV or 110kV lines or lines with higher voltages, and safety distances become greater.
Description
Technical field
The utility model relates to a kind of compact insulating support, belongs to 10kV distribution overhead line field.
Background technology
In current many times overhead wires of 10kV, the insulated wire hanging point of shaft tower is arranged and is rounded projections arranged, and one upper, two-phase under (as shown in Figure 2).Especially 4 times and above overhead wire, meet over the ground safe distance and alternate safe distance under condition, shaft tower height can be very high, cause a large amount of uses of steel, greatly increased construction costs, economy is not high, also can cause scissors crossing or bore difficulty more in some special location.
Utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: a kind of designs simplification is provided, can reduces many times overhead line pole tower height degree, saves required steel, reduces the compact insulating support of construction costs.
Compact insulating support described in the utility model, comprise the cross-arm being fixed on shaft tower, three horizontal aerial insulated wire hanging points are set on every cross-arm of the every side of shaft tower, and the three phase isolated line of every time overhead wire is separately fixed on three aerial insulated wire hanging points.
This compact insulating support by arranging three horizontal aerial insulated wire hanging points on every cross-arm of the every side of shaft tower, thereby can meet the line-to-ground safe distance of 10kV Regulations defined and alternate safe distance etc. various safe distances under prerequisite, by the A of every time overhead wire, B, the arranged of C three phase isolated line on shaft tower, be horizontal.The material that this compact insulating support adopts is still traditional steel, by adopting this compact insulating support, can obviously reduce the height of shaft tower (especially steel pipe pole), thereby saving great deal of steel, greatly reduce construction costs, it is especially obvious that economy embodies in a fairly large number of overhead wire engineering of steel pipe pole, successfully solved the problem of current many times overhead line pole tower height Du Taigao, steel waste.
The beneficial effect that the utility model compared with prior art had is:
This compact insulating support structure design is ingenious rationally, A, B, the C three phase isolated line that by this support, can realize every time overhead wire are horizontal on shaft tower, thereby can reduce the height that takies, reduces shaft tower (especially steel pipe pole) to vertical space, save great deal of steel, reduce construction costs, greatly improved economy, make simultaneously many times overhead wires of 10kV bore more 35kV, 110kV and more voltage levels circuit become more feasible, it is larger that safe distance becomes.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of shaft tower in prior art.
In figure: 1, aerial insulated wire hanging point; 2, cross-arm; 3, shaft tower.
The specific embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
As shown in Figure 1, 2, this compact insulating support comprises the cross-arm 2 being fixed on shaft tower 3, three horizontal aerial insulated wire hanging points 1 are set on every cross-arm 2 of shaft tower 3 every sides, and the three phase isolated line of every time overhead wire is separately fixed on three aerial insulated wire hanging points 1.
This compact insulating support is by arranging three horizontal aerial insulated wire hanging points 1 on every the cross-arm 2 in shaft tower 3 every sides, thereby can meet the line-to-ground safe distance of 10kV Regulations defined and alternate safe distance etc. various safe distances under prerequisite, by the A of every time overhead wire, B, the arranged of C three phase isolated line on shaft tower 3, be horizontal.The material that this compact insulating support adopts is still traditional steel, by adopting this compact insulating support, can obviously reduce especially steel pipe pole of shaft tower 3() height, thereby saving great deal of steel, greatly reduce construction costs, it is especially obvious that economy embodies in a fairly large number of overhead wire engineering of steel pipe pole, successfully solved the problem that current many times overhead wire shaft towers 3 are highly too high, steel are wasted.
For instance, in 4 times overhead wires, adopt after compact insulating support, 4 times the shared vertical space of aerial insulated wire is only half in current triangle arrangement situation, so the shaft tower 3(height of steel pipe pole especially) just can significantly reduce.The benefit highly reducing, the one, greatly improved economy, can be by the overhead wire engineering that same fund is built or maintenance is longer, the 2nd, make many times overhead wires of 10kV bore more 35kV, 110kV and more voltage levels circuit become more feasible, it is larger that safe distance becomes.Adopt compact insulating support even can make to set up the location that multi circuit transmission lines cannot realize at present at some and become feasible.If overhead wire surpasses 4 times, effect can be more obvious.
