Abstract
A glass insulator comprises a circular disc shaped glass element of which the middle portion is protrude upwardly, a steel leg is glued on the inner side of the protrusion of the glass element via a cement binder, a steel cap is glued on the outside of the protrusion of the glass element via the cement binder, a locking pin is arranged in an upper cavity of the steel cap, a gasket is arranged between the steel cap and the glass element, two radial extension main umbrella skirts are arranged on the glass element, wherein the upper umbrella skirt outwards extends from the roof portion of the protrusion of the glass element, the main lower umbrella skirt is connected with the middle of the upper main umbrella skirt, the upper main umbrella skirt and the lower main umbrella skirt obliquely extends outwards, and the inclination of the lower main umbrella skirt is larger than that of the upper main umbrella skirt. The glass insulator has the advantages of improving the property of dirt resistance of the insulator, and bringing convenience to clean accumulated dirt.
Description
Technical field
The utility model relates to electric power and carries equipment technical field, particularly a kind of glass insulator.
Background technology
Traditional two umbrella glass insulators, form is single, extends as the main chute skirt radial level of the glass workpiece of critical piece, and aerodynamic principle very not is unfavorable for that natural air removes full skirt surfaces externally and internally contamination to greatest extent automatically.In addition, be provided with the short umbrella rib of several concentric circless below traditional glass insulator main chute skirt, be unfavorable for that also natural air removes full skirt inner surface contamination to greatest extent automatically.This structural characteristics make glass insulator be easy to generate the pollution flashover phenomenon.
Summary of the invention
The purpose of this utility model is to solve the deficiency that prior art exists, and a kind of principle of aerodynamic more is provided, and helps the glass insulator that natural air is removed full skirt surfaces externally and internally contamination to greatest extent automatically.
For achieving the above object, solution of the present utility model is: a kind of glass insulator, comprise middle disk-shaped glass part to upper process, glue together the steel pin in this glass workpiece jut inboard by cement glue, glue together the steel cap in the glass workpiece jut outside by cement glue simultaneously, upper cavity at the steel cap, a locking pin is installed, between steel cap and glass workpiece, a packing ring is installed, glass workpiece has the main chute skirt of twice radial extension, wherein going up the main chute skirt outwards extends from the jut root in the middle of the glass workpiece, following main chute skirt is connected with last main chute skirt middle part, it is characterized in that: the described main chute skirt of going up is tilted to outer the extension with following main chute skirt, and following main chute skirt is bigger than the gradient of last main chute skirt.
As preferably, there is not short umbrella rib below the main chute skirt.
Compared with prior art, advantage of the present utility model is: the main chute skirt that radial skew extends, the aerodynamic principle, help natural air and remove full skirt surfaces externally and internally contamination to greatest extent automatically, and the full skirt upper surface that tilts helps draining, especially from high to low gradient is bigger than the gradient of last main chute skirt from inside to outside to play the main chute skirt, has improved the self-cleaning property of insulator, thereby has improved the dirty performance of resistant of insulator; And do not have short umbrella rib to help cleaning contamination below the main chute skirt.
Description of drawings
Fig. 1 is a part section structural representation of the present utility model
In the accompanying drawings, the corresponding relation of parts and numbering thereof is as follows: the 1-glass workpiece; 2-packing ring, 3-steel pin; The 4-chapeau de fer; The 5-cement glue; The 6-locking pin; The last main chute skirt of 7-; Main chute skirt under the 8-.
Embodiment
Glass insulator as shown in Figure 1, comprise middle disk-shaped glass part 1 to upper process, inboard at this glass workpiece 1 jut by cement glue 5 gummed steel pin 3, glue together steel caps 4 in the glass workpiece 1 jut outside by cement glue 5 simultaneously, upper cavity at steel cap 4, a locking pin 6 is installed, between steel cap 4 and glass workpiece 1, a packing ring 2 is installed, glass workpiece 1 has the main chute skirt of twice radial extension, wherein going up main chute skirt 7 outwards extends from the jut root in the middle of the glass workpiece 1, following main chute skirt 8 is connected with last main chute skirt 7 middle parts, and the described main chute skirt 7 of going up is tilted to outer the extension from inside to outside from high to low with following main chute skirt 8, and following main chute skirt 8 is bigger than the gradient of last main chute skirt 7, and, there is not short umbrella rib below the main chute skirt.
