The special-shaped composite insulator of arrangement.
Background technique
Composite insulator is widely used in overhead power transmission because having many advantages, such as that anti-pollution characteristic is good, light weight, high mechanical strength
Route.The excellent electric properties of composite insulator have benefited from its umbrella skirt construction and core bar jacket is high-temperature silicon disulfide rubber material
Matter, one side silastic material hydrophobicity performance with super strength, another aspect silastic material have preferable migration of hydrophobicity special
Property, using the generation for showing that composite insulator can effectively prevent pollution flashover.Although composite insulator has so many excellent
Point, however, the inclined-plane umbrella skirt construction of composite insulator is because vertical direction is with biggish exposure when meeting with sleet and snow ice weather
Area causes icing to increase on full skirt surface, and after ice sheet reaches certain thickness, full skirt is big-eared under the effect easily by icing gravity,
Full skirt is bridged by sleet above and below causing, and after whole branch insulator is bridged by sleet, greatly reduces the flashover voltage of the insulator, pole
Ice easily occurs to dodge, jeopardizes power grid security;On the other hand, common composite insulator umbrella skirt is relatively thin, and ice sheet makes big-eared generation under full skirt
Deformation, after multiple icing, permanent deformation may occur for full skirt, influence its service life.Existing technical measures are that ice occurs
It dodges or is replaced in time after deforming, however, above-mentioned not only walkaround inspection heavy workload, and need high altitude operation that there is biggish danger
Property.

Fitting 7 is pressed from both sides to connect;
The umbrella skirt construction is plane umbrella skirt construction, and mutual parallelly distribute on, full skirt plane is in heeling condition
It is in be vertically arranged on plug 4.
Further, the inclination of the angle where the umbrella skirt construction between plane and plug 4 and 4 relative level of plug
Angle complementary angle each other.
Further, the center of the umbrella skirt construction is respectively positioned on the axis of plug 4, and umbrella skirt construction is located at plug 4
The thickness of the upper half is greater than the thickness of 4 lower half of plug.
Further, the umbrella skirt construction is maximum relative to the top thickness of plug, and the umbrella skirt construction is relative to plug
Bottom thickness it is minimum, the gradient thickness transition connection between the top-to-bottom of the umbrella skirt construction.
Further, the edge of the umbrella skirt construction is arranged to streamlined arc edge.
In the special-shaped composite insulator of the inclination arrangement of the utility model, the umbrella skirt construction includes at least two groups difference
The disk full skirt of area size is staggeredly fixed on plug 4 between the disk full skirt of different area size.
Further, the umbrella skirt construction is thickness in 4~10 times of the disk knot that 1~10mm, radius are plug radius
Structure.
Further, the umbrella skirt construction which is provided with using sulphurated siliastic by integral injection molding for plug
The through-hole passed through, and be sleeved on plug 4 by the through-hole interference or bonding.
Further, the plug 4 is glass plug, has wrapped insulating sheath thereon.
Further, the ball-and-socket fitting 1 and connection wire clamp gold of connection cross-arm 6 is fixedly installed in the both ends of the plug 4 respectively
The bulb fitting 5 of tool 7.
The utility model achievees the purpose that less icing and contamination by changing insulator contour structures, utilizes two groups of inclinations
The plug of arrangement holds power transmission line, by using the plug of heeling condition, can be arranged to the full skirt insulator being fixed on plug
Be vertically arranged, in this way by the umbrella skirt construction of insulator and horizontal plane, and upper thick and lower thin umbrella skirt construction it is most thick with most
Thin position is in same perpendicular, is greatly reduced umbrella skirt construction in this way in the exposed area of vertical direction, is on the one hand subtracted
Lack its collision area with sleet, on the other hand, the arrangement of the umbrella cover entirety near vertical of umbrella skirt construction, filthy particle, rain
Snow etc. is acted on by self gravity to be not easy to retain in the umbrella cover of umbrella skirt construction, reduces contamination and icing.
In addition, the insulator of the utility model uses upper thick and lower thin polymorphic structure, the upper full skirt of face sleet impact is adopted
With reinforcing designing, even if icing, full skirt is also not easy down big-eared, not will cause its performance of insulator influence of crust deformation, while the side of full skirt
Edge uses streamlined structure, advantageously reduces the windage of insulator entirety.
From the above mentioned, the utility model uses the special-shaped composite insulator of above-mentioned inclination arrangement, can effectively reduce insulation
Sublist face icing and contamination amount are greatly reduced ice and dodge and pollution flashover probability, while composite insulator umbrella caused by being greatly decreased because of icing
The deformation of skirt improves the service life of insulator, reduces the high altitude operation of maintenance replacement insulator.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
