Abstract
The utility model relates to a disc double-umbrella porcelain composite insulator. The disc double-umbrella porcelain composite insulator comprises a silicone rubber creepage-increasing umbrella (3) connected to an upper umbrella (1-1); the silicone rubber creepage-increasing umbrella (3) includes an annular main body, an extending outer ring (3-1 ) which is arranged at the periphery of the annular main body, and an inner buckling ring (3-2) which is arranged under the junction of the annular main body and the extending outer ring (3-1); a lower side surface of the annular main body abuts against an upper side surface of the upper umbrella (1-1). By adopting the above structure, on the one hand, hydrophobicity of the insulator is increased, and on the other hand, the insulator is provided with a longer creepage distance. The disc double-umbrella porcelain composite insulator can be applied to high-voltage transmission line tension strings, substations and overhead transmission lines in a populated area. The disc double-umbrella porcelain composite insulator is advantageous in avoidance of RTV coating, reduced sweeping frequency, decreased frequency of power failure and improved operational reliability.
Description
Technical field
The utility model relates to a kind of insulator that is used for ultra-high-tension power transmission line.
Background technology
The two following shortcomings of umbrella porcelain insulator ubiquity of existing dish type: the first, creepage distance is little; The second, hydrophobicity performance is poor.A kind of porcelain composite insulator is arranged in the market, adopt silicon rubber that porcelain spare is all coated, require during preparation to adopt the HTHP sulfuration process, be easy to damage porcelain spare.
The utility model content
The utility model technical problem to be solved is, provides a kind of dish type two umbrella porcelain composite insulators, has bigger creepage distance and better hydrophobicity performance, and can effectively protect porcelain spare, and avoid partial discharge.
The utility model has adopted following technical scheme:
The two umbrella porcelain composite insulators of a kind of dish type comprise porcelain spare, and said porcelain spare comprises the main part and the last umbrella and the subumbrella that are positioned at main part bottom periphery at middle part, it is characterized in that: comprising also that the silicon rubber that is connected on the said upward umbrella increases climbs umbrella; Said silicon rubber increases climbs the extension outer shroud that pack is drawn together circumferential body and is positioned at the circumferential body periphery; Said silicon rubber increases climbs umbrella and also comprises and be positioned at circumferential body and the internal buckle ring that extends outer shroud intersection below, said circumferential body, extends outer shroud and internal buckle ring is structure as a whole; Wherein, the downside of said circumferential body and the said upper side of going up umbrella fit tightly.
Between the upper side of the downside of circumferential body and last umbrella, also be coated with adhesive layer.
The good effect of the utility model is:
The first, umbrella is compounded with silicon rubber and increases and climb umbrella on the porcelain spare, and silicon rubber increases and climb umbrella and have the extension outer shroud, has increased the hydrophobicity of insulator on the one hand, makes insulator have bigger creepage distance on the other hand.Be applied on the overhead transmission line of high-voltage power line tension string, transformer station and personnel's congested area, can exempt RTV coating and apply, reduce the cleaning frequency, reduce frequency of power cut, improve reliable degree.
The second, the HTHP sulfuration process is not used in the preparation of the utility model, can not damage porcelain spare, and rate of finished products increases substantially.
Three,Through vacuum treatment, silicon rubber increases climbs umbrella and porcelain spare fits tightly, and has eliminated the gap, can effectively avoid partial discharge.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Further specify the utility model below in conjunction with accompanying drawing and embodiment.
Like Fig. 1, present embodiment comprises steel pin 2 and the steel cap 6 that is positioned at directly over the steel pin 2.Upper end at steel pin 2 is fixed with porcelain spare 1 through inner concrete layer 4, and said porcelain spare 1 comprises the main part and the last umbrella 1-1 and the subumbrella 1-2 that are positioned at main part bottom periphery at middle part.Said steel cap 6 fixes through the main part upper end of outer concrete layer 5 with porcelain spare 1, and steel cap 6 coats the upper end of porcelain spare 1 main part through outer concrete layer 5.
The special feature of the utility model is, comprises also that the silicon rubber that is connected on the said umbrella 1-1 of going up increases to climb umbrella 3; Said silicon rubber increases climbs the extension outer shroud 3-1 that umbrella 3 comprises that circumferential body is peripheral with being positioned at circumferential body; Also comprise being positioned at circumferential body and the internal buckle ring 3-2 that extends outer shroud 3-1 intersection below, said circumferential body, extension outer shroud 3-1 and internal buckle ring 3-2 are structure as a whole.Wherein, the downside of said circumferential body and the said upper side of going up umbrella 1-1 fit tightly; Said extension outer shroud 3-1 is fastened on the outer face of the said umbrella 1-1 of going up.More firm in order silicon rubber to be increased climb umbrella 3 to combine with last umbrella 1-1, between the upper side of the downside of circumferential body and last umbrella 1-1, also be coated with adhesive layer, in order to the downside of gummed circumferential body with said on the upper side of umbrella 1-1.
During preparation the utility model,, silicon rubber is increased climb umbrella 3 and the mutual socket of last umbrella 1-1 then, vacuumize processing at last, the downside of circumferential body and the upper side of last umbrella 1-1 are fitted tightly, eliminate the gap at first at the upper side coating adhesive adhesion coating of last umbrella 1-1.
Claims (2)
1. two umbrella porcelain composite insulators of a dish type; Comprise porcelain spare (1); Said porcelain spare (1) comprises the main part and the last umbrella (1-1) and the subumbrella (1-2) that are positioned at main part bottom periphery at middle part, it is characterized in that: also comprise be connected said on silicon rubber on the umbrella (1-1) increase and climb umbrella (3); Said silicon rubber increases climbs the extension outer shroud (3-1) that umbrella (3) comprises that circumferential body is peripheral with being positioned at circumferential body; Said silicon rubber increases climbs umbrella (3) and also comprises and be positioned at circumferential body and the internal buckle ring (3-2) that extends outer shroud (3-1) intersection below, said circumferential body, extends outer shroud (3-1) and internal buckle ring (3-2) is structure as a whole; Wherein, the downside of said circumferential body and the said upper side of going up umbrella (1-1) fit tightly.
2. the two umbrella porcelain composite insulators of dish type as claimed in claim 1 is characterized in that: between the upper side of the downside of circumferential body and last umbrella (1-1), also be coated with adhesive layer.
