Abstract
The utility model relates to an anti-icing type composite insulator structure, which comprises a core rod, a sheath and umbrella skirts. The sheath covers the outer side of the core rod. The umbrella skirts are integrally formed on the outer side of the sheath. The insulator structure is innovative in that the largest umbrella skirts each have a 300-millimeter diameter; the distance between two adjacent largest umbrella skirts is 500 mm to 550 mm; and the diameter of the core rod ranges from 18 mm to 40 mm. By arranging the largest umbrella skirts each with a diameter more than 1.6 times those of other umbrella skirts on the sheath and making the distance between adjacent largest umbrella skirts range from 500 mm to 550 mm, the insulator structure enables the largest umbrella skirts to well protect other umbrella skirts within a certain range. The insulator structure has the capabilities of resisting rain flashover and ice flashover enhanced.
Description
Technical field
The utility model relates to a kind of composite insulator structure, particularly a kind of ice-covering-proof type composite insulator structure.
Background technology
Insulator is for the tenaculum electric conductor and makes the electric elements of its insulation, uses very wide in electric power system.Composite insulator is High-Voltage Insulation of being made by organic silicon rubber material.It is owing to have good hydrophobicity, ageing resistance, proof tracking and electrical erosion resistance, and mechanical strength is high, shock resistance, shockproof and anti-brittle failure performance are good, the advantage such as lightweight and be widely used in the bus of overhead transmission line, power plant and electric substation and the external belt electric conductor of various electric equipments.
Full skirt specification in the same composite insulator has several; its diameter is more or less the same; under heavy rain or heavy rain, may connect into chain during rainwater; cause that rain dodges, ice dodges; therefore be rainproof sudden strain of a muscle, the ice sudden strain of a muscle ability that improves composite insulator; the full skirt of a maximum gauge can be set in the top of composite insulator usually, and its diameter and other full skirt diameters differ larger, thereby avoid forming current.But also there is a shortcoming in it: because the length of insulator is longer, the limited coverage area of maximum full skirt can only be playing a role near the full skirt on top.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of rainproof sudden strain of a muscle, the good ice-covering-proof type composite insulator structure of ice sudden strain of a muscle ability.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of ice-covering-proof type composite insulator structure, comprise plug, sheath and full skirt, mandrel outer is coated with sheath, the outer monolithic devices of sheath has full skirt, its innovative point is: the maximum full skirt diameter of described full skirt is 300mm, and the spacing of described adjacent maximum full skirt is 500-550mm; The diameter of described plug is 18-40mm.
The utility model has the advantage of: surpass the maximum full skirt of other full skirt diameters more than 160% sheath setting; and spacing is 500-550mm between the adjacent maximum full skirt; so that maximum full skirt can be good at protecting other full skirts to the range section between next maximum full skirt, improve rainproof sudden strain of a muscle, ice sudden strain of a muscle ability.
Description of drawings
Fig. 1 is the utility model composite insulator structure schematic diagram.
Embodiment
As shown in Figure 1, comprise plug 1, sheath 2 and full skirt 3, plug 1 is coated with sheath 2, and sheath 2 outer global formations have full skirt 3, and maximum full skirt 35 diameters of full skirt are 300mm, and the spacing of adjacent maximum full skirt 35 is 500-550mm; The diameter of plug 1 is 18-40mm.
What each size mandril was corresponding is respectively except each full skirt 31,32,33 in the full skirt group between the maximum full skirt, 34 diameter:
Diameter 18 mm plugs: the full skirt diameter is followed successively by 78 mm-108 mm-78 mm-138 mm; Diameter 24 mm plugs: the full skirt diameter is followed successively by 105 mm-135 mm-105 mm-165 mm; Diameter 28mm plug: the full skirt diameter is followed successively by 111 mm-141 mm-111 mm-171 mm; Diameter 30mm plug: the full skirt diameter is followed successively by 111 mm-141 mm-111 mm-171 mm; Diameter 34 mm plugs: the full skirt diameter is followed successively by 115 mm-145 mm-115 mm-175 mm; Diameter 40 mm plugs: the full skirt diameter is followed successively by 122 mm-152 mm-122 mm-182 mm.The maximum full skirt diameter of all each plugs 1 is 300mm.
