Abstract
The utility model relates to an insulation creepage cap assembled with an electric suspension insulator, which comprises a suspension insulator with a metal cap, and is characterized in that: a creepage cap is fixed on the metal cap of the electric suspension insulator, and is of a hollow cylindrical shape, and a creepage edge is arranged at the top part of the creepage cap. The utility model has the beneficial effects that: the external insulation creepage distance of the suspension insulator, the insulation value and the pollution flashover voltage are increased; the dryness of the insulator under hot and humid environment is enhanced, so the insulation level and the pollution flashover voltage are improved; because the product is assembled on the metal cap of the insulator, the important 'fault spontaneous explosion' display function of a glass insulator is not affected; and the pollution flashover voltage of the suspension insulator can be increased by over 1.5 times.
Description
Technical field
The utility model belongs to electric power power transmission and transformation external insulation equipment, relates in particular to the insulating creepage increasing cap of the additionally installed on electric suspension type insulator in a kind of electric power power transmission and transformation external insulation equipment.
Background technology
Electric suspension type insulator is the product of electric power power transmission and transformation, electrical network external insulation widespread usage.Its function is for ensureing the safe operation of electrical network external insulation.Its important function index is its antifouling sudden strain of a muscle magnitude of voltage.The material of electric suspension type insulator is generally porcelain or glass material.At present, there is following important technological problems in this product: antifouling sudden strain of a muscle magnitude of voltage is low; Some insulator to glass material installs additional and increases the transformation of climbing product, having influence on the self-destruction function of glass insulator " the full skirt self-destruction function of glass insulator is after suspension insulator loses insulating properties; and become the Presentation Function of fault null value; it can show the insulator product bug automatically, in time; thus the accident of electrical network avoided, ensure the safe operation of electrical network.Electric power power transmission and transformation and electrical network demand improving the shortcoming of the said goods urgently.
The utility model content
The purpose of this utility model is to overcome the deficiency of above-mentioned functions, and provide a kind of insulating creepage increasing cap of additionally installed on electric suspension type insulator, creepage increasing cap adopts the silicon rubber material of high insulating property, it is installed in the metal cap position of insulator, can improve the pollution flashover voltage value of electric suspension type insulator, not influence the self-destruction performance of glass insulator.
The utility model for achieving the above object, by the following technical solutions: a kind of insulating creepage increasing cap of additionally installed on electric suspension type insulator, comprise the suspension insulator that has metal cap, it is characterized in that: fixing creepage increasing cap on the metal cap of described electric suspension type insulator, described creepage increasing cap is a hollow cylindrical, and its top is provided with to increase climbs the edge.
Beneficial effect: increased the external insulation creepage distance of suspension insulator, improved insulation values, improved its pollution flashover voltage value; Strengthen the aridity of insulator in hygrothermal environment, thereby also improved its insulation level, improved the pollution flashover voltage value; Because of product is to be installed on the insulator metal cap, thereby do not influence the important " self-destruction " Presentation Function of glass insulator; Suspension insulator pollution flashover voltage value can improve more than 1.5 times.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing and preferred embodiment.As shown in the figure,
A kind of insulating creepage increasing cap of additionally installed on electric suspension type insulator comprises the suspension insulator 1 that has metal cap 3, fixing creepage increasing cap 2 on the metal cap of described electric suspension type insulator, and described creepage increasing cap is a hollow cylindrical, its top is provided with to increase climbs the edge.Suit portion adopts the silica gel adhesive bonding, promptly finishes the improvement to suspension insulator.
Creepage increasing cap can increase the creepage distance of insulator dielectric part.Creepage increasing cap uses good silicon rubber insulation material, is installed on the suspension insulator metal cap, can make the suspension insulator metal cap outside of conduction become the surface of insulation.Therefore the creepage distance of insulation and the insulation values of suspension insulator have been increased.Because creepage increasing cap has installed insulator metal cap part additional, therefore do not influence the self-destruction function of glass insulator glass full skirt.These technical measures are applicable to the suspension insulator of the various electric pressures of electric power.Its application will significantly improve the safe operation of power external insulation.
The above only is preferred embodiment of the present utility model, is not structure of the present utility model is done any pro forma restriction.Every foundation technical spirit of the present utility model all still belongs in the scope of the technical solution of the utility model any simple modification, equivalent variations and modification that above embodiment did.
