Abstract
A double-umbrella glass insulator comprises a disk-shaped glass piece with the upwardly-protruded middle part. The inner side of the protruded part of the glass piece is glued with a steel leg through cement compo; the outer side of the protruded part of the glass piece is glued with a steel cap through cement compo; an R-type locking pin and a W-type locking pin are arranged in the cavity at the upper part of the steel cap; a gasket is arranged between the steel cap and the glass piece; and the glass piece is provided with two main umbrella skirts extending in the radial direction, wherein, the upper main umbrella skirt extends outwards from the protruding part arranged in the middle of the glass piece, the lower main umbrella skirt is connected with the middle of the upper umbrella skirt, the upper main umbrella skirt and the lower main umbrella skirt extend outwards, one or three concentric round-shaped umbrella fringes are arranged below the upper main umbrella skirt or in the interior of the lower main umbrella skirt. The double-umbrella insulator has the advantages of improving the pollution-resistance performance of the insulator and increasing the creepage distance.
Description
Technical field
The utility model relates to defeated, the power transformation equipment technical field of electric power, particularly a kind of toughened glass insulator.
Background technology
Traditional toughened glass insulator, form is single, anti-pollution type toughened glass insulator particularly is under the condition that disk track limits, in order to satisfy the requirement of creepage distance, have to significantly increase the height of umbrella rib and external shed, this design feature does not only meet aerodynamic principle, is unfavorable for that natural air and rainwater remove the filth of umbrella edge surface and main chute skirt inner surface automatically, make glass insulator be easy to generate contamination, cause 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 help natural air and rainwater and remove umbrella edge surface and the filth of main chute skirt inner surface automatically, and the lower two umbrella glass insulators of umbrella rib.
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, it is characterized in that: glass workpiece has the main chute skirt of twice radial extension, wherein goes up the main chute skirt and outwards extends from the jut root in the middle of the glass workpiece, and following main chute skirt is connected with last main chute skirt middle part, the described main chute skirt of going up is tilted to outer the extension with following main chute skirt, below last main chute skirt, the inside of following main chute skirt is provided with together or three road circular parachute ribs.
As preferably, in that being set, three road circular parachute ribs get under the situation, and each road circular parachute rib is concentric.
As preferably, described locking pin adopts R type pin or W type pin.
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, thereby improves the dirty performance of resistant of insulator; Simultaneously, the additional umbrella rib design of two full skirts under the limited condition of insulator disk track, has further increased creepage distance; Particularly under the situation that three road circular concentric umbrella ribs are set, the highly significant of this pair umbrella glass insulator umbrella rib reduces, and helps cleaning contamination and reduces the insulator volume.
