With the creepage-increasing cap adopted, the pollution flashover voltage value of an electric power suspension insulator can be improved, and the spontaneous explosion performance of an glass insulator will not be affected; the porcelain insulator is coated with the TiO2 film which is sintered to form the TiO2 sintering layer, and therefore, the surface of a porcelain body can have a photocatalytic decomposition ability, such that organic substances attached on the surface of the porcelain body can be decomposed, as a result, inorganic substances attached on the surface of the porcelain body can fall off more easily under the effects of wind and rain, and as a result, the requirement for anti-pollution flashover ability of the porcelain insulator can be satisfied.
Description
Technical field
The utility model relates to a kind of power equipment suspension insulator, relates in particular to a kind of anti-pollution flashover suspension insulator with insulating creepage increasing cap.
Background technology
Electric suspension type insulator is the product that electric power power transmission and transformation, electrical network external insulation are generally applied.Its function is for ensureing the safe operation of electrical network external insulation.Its important functional parameter is its anti-pollution flashover voltage value.The material of electric suspension type insulator is generally porcelain or glass material.At present, there is following important technological problems in this product: anti-pollution flashover voltage value is low; Some insulator to glass material installs additional and increases the transformation of climbing product, has influence on the self-destruction function of glass insulator.And common porcelain insulator is under filthy wet condition, and insulator is made the used time insulation property at power-frequency voltage and sharply descended, and often produces local distribution inhomogeneous, and the position of at electric field, concentrating often causes corona, thereby produces radio interference.Inhomogeneous voltage distributes, and very easily causes porcelain body aging.The Main Means that prevents at present pollution flashover is the hand sweeping insulator, and time-consuming, effort and maintenance cost drop into very large.
The utility model content
The purpose of this utility model is to overcome the deficiency of above-mentioned functions, and provide a kind of anti-pollution flashover suspension insulator with insulating creepage increasing cap, its 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 affect the self-destruction performance of glass insulator.Apply one deck TiO on porcelain insulator
2Film also carries out sintering formation TiO
2Sinter layer, make the porcelain body surface have the photocatalysis Decomposition ability, can be the organic substance decomposing that is attached to the porcelain body surface, and inorganic matter adhered thereto is easier to come off under wind-force, rainwater effect thereby make, to reach the requirement that improves the anti-pollution flashover ability of porcelain insulator.
The utility model for achieving the above object, by the following technical solutions: a kind of anti-pollution flashover suspension insulator with insulating creepage increasing cap, comprise the suspension insulator 1 with metal cap 3, it is characterized in that: fixing creepage increasing cap 2 on the metal cap of described suspension insulator, described creepage increasing cap is hollow cylindrical, and its top is provided with to increase climbs edge; Suspension insulator porcelain insulator on apply one deck TiO
2Film also carries out sintering formation TiO
2Sinter layer 4.
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 product is to be installed on the insulator metal cap, thereby do not affect important " self-destruction " Presentation Function of glass insulator; Suspension insulator pollution flashover voltage value can improve more than 1.5 times; Insulator TiO
2Sinter layer is not under ultraviolet irradiation at the visible light thing, has the catalytic decomposition ability, can decompose the organic substances such as oil, phenol, due to organic degraded, can reduce greatly the adhesive force of inorganic matter, it is easilier come off under the effect of wind-force, rainwater, namely improve the stain resistance of porcelain insulator, thereby improve the surface appearance of insulator, and then reduce the power outage that causes because of pollution flashover; Under without the strong illumination condition, TiO
2Film sintered layer has certain hydrophobic effect, so under the wet weather conditions such as drizzle, mist, snow, dew, TiO
2Film sintered layer surface is difficult for forming complete moisture film, and the conductive ion of dunghill after by water-soluble solution is difficult to form conductive channel, thereby the ability of withstand voltage improves greatly.
Description of drawings
Fig. 1 is 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 anti-pollution flashover suspension insulator with insulating creepage increasing cap, comprise the suspension insulator 1 with metal cap 3, fixing creepage increasing cap 2 on the metal cap of described suspension insulator, and described creepage increasing cap is hollow cylindrical, its top is provided with to increase climbs edge; Suspension insulator porcelain insulator on apply one deck TiO
2Film also carries out sintering formation TiO
2Sinter layer 4.Suit section adopts the silica gel adhesive bonding, namely completes 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 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 affect 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.Insulator TiO
2Sinter layer is not under ultraviolet irradiation at the visible light thing, has the catalytic decomposition ability, can decompose the organic substances such as oil, phenol, due to organic degraded, can reduce greatly the adhesive force of inorganic matter, it is easilier come off under the effect of wind-force, rainwater, namely improve the stain resistance of porcelain insulator, thereby improve the surface appearance of insulator, and then reduce the power outage that causes because of pollution flashover; Under without the strong illumination condition, TiO
