Embodiment
For those skilled in the art can understand technical scheme provided by the utility model better, set forth below in conjunction with specific embodiment.
Present embodiment provides a kind of suspension insulator, and suspension insulator comprises the full skirt string that a plurality of full skirts are formed, and improvements of the present utility model are, to the improvement of umbrella skirt construction.
See also Fig. 2, Fig. 2 is the schematic diagram of the umbrella skirt construction that provides of present embodiment.
Full skirt comprises central part 201, connecting portion 202 and end 203, and described connecting portion 202 is the connecting portion of chamfer shape, and described connecting portion 202 connects described central part 201 and end 203.As can be seen from Figure 2, connecting portion 202 be shaped as chamfer shape, such shape can be saved material more with respect to the structure of the projection of prior art, therefore can save cost, in addition, this chamfering structure can be saved more space with respect to the structure of projection, for other operation provides more operating space.
In order more clearly to disclose size of the present utility model, see also Fig. 3, Fig. 3 is the mark figure of the umbrella skirt construction shown in Fig. 2.The unit of the size among the figure is mm.The radius of the chamfering of the connecting portion 202 shown in the figure is 50mm, also can use other chamfer dimesion, and the radius that generally is preferably chamfering is more than the 40mm (millimeter); More preferably, the radius of chamfering is more than 50mm, and most preferably, the radius of chamfering is more than 60mm.Chamfer radius is big more, and the transition between central part and the end is also just more level and smooth, if but chamfer radius is excessive will to become linear connecting portion, and the space of saving is with limited.
The umbrella skirt construction of present embodiment no longer adopts ceramic material or glass material, but adopts the less silastic material of density.Silicon rubber has multiplely all can be selected for use, for example dimethyl silicone rubber (abbreviation methyl silicone rubber), methyl vinyl silicone rubber (abbreviation vinylsiloxane rubber), methyl phenyl vinyl silicone rubber (abbreviation phenyl siloxane rubber), fluorine silicon, nitrile silicone rubber, penylene and phenylate support silicon rubber etc.Adopt silastic material to make, with respect to porcelain suspension insulator or glass suspension insulator, because density is low, weight has obtained alleviating greatly, can reduce the load to iron tower, and dismounting and installation are all comparatively convenient; And silicon rubber can improve, and anti-soil dodges, mist sudden strain of a muscle performance is strong, the wet sudden strain of a muscle and the fog lightning pressure height; And difficult fragmentation, anti-gunslinging are transported light.Silicon rubber formed convenience can shot moulding.
Big full skirt and little full skirt are arranged in the full skirt string in the present embodiment, and described big full skirt is bigger than described little full skirt.Big cluster parachute is called for short gamp, and the umbellule skirt is called for short umbellule.The equal proportion that described big full skirt is described little full skirt is amplified.Preferably, the ratio of amplification is more than 1.1 times.Multiplication factor is 1.2 times in the present embodiment.
The arrangement mode of big full skirt and little full skirt as shown in Figure 4.Fig. 4 is the arrangement mode schematic diagram of big cluster parachute and little full skirt in the present embodiment.Gamp in the full skirt string and umbellule adopt the form of alternately arranging in twos.Should various spread patterns all can realize, the preferred still arrangement mode shown in the embodiment that uses, arranges more regular, stressed comparatively evenly dispersion, and comparatively attractive in appearance.In the present embodiment, gamp and umbellule string together by the fiber-reinforced resin matrix compound material rod of centre, also can adopt other barred body material.Fiber-reinforced resin matrix compound material, what use in the present embodiment is glass fiber reinforced epoxy resin based composites rod.Fiber can also adopt organosilicon/polyamide 6 amine fiber, aramid fiber even carbon fiber etc., wherein adopt the good insulating of glass fibre and aramid fiber, preferably use this two kinds of fibers, in addition, glass fibre is with respect to the aramid fiber low price, so preferably use glass fibre as reinforcing material.Resin preferably uses epoxy resin or unsaturated polyester resin, considers from the toughness aspect, preferably adopts the epoxy resin through toughening modifying, not only has strength character, and has good impact property.Silicon rubber full skirt string is except using the gamp shown in the present embodiment, the mode accident that umbellule strings together by galss fiber reinforced resin based composites rod, can also adopt other form to make, all be acceptable as long as can realize being prepared into the mode of silicon rubber full skirt string.
Need to prove that full skirt can be made by silicon rubber in the present embodiment, also can adopt other inorganic material to make,, also can just have other organic material to make, as abrasive rubber, epoxy elastomer as glass, pottery etc.Be not limited to certain specific material.Just adopt the mode effect of silicon rubber better,, do not repeat them here as for addressing above the effective reason.
The difference of present embodiment and embodiment 1 is:
Gamp in the full skirt string and umbellule adopt single form of alternately arranging.Be that arrangement mode is a full skirt, little full skirt, another big full skirt, another little full skirt ....Adopt in such a way and also can realize.
Certainly, also can adopt irregular arrangement mode, perhaps according to the specific arrangement mode of practice of construction needs design.
Suspension insulator provided by the utility model compared with prior art, central part adopts chamfering to be connected with the end, connected mode with respect to projection, the connected mode of chamfering more can economical with materials, and for bigger operating space is provided in the full skirt installation process, but also can be with the stressed central part that passes to of end, the size of central part is bigger, can bear bigger active force, therefore can bring into play the effect of suspension insulator.
Suspension insulator provided by the utility model is specially adapted to the application in ultra-high-tension power transmission line field.
The above only is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
