Problems solved by technology

One of the disadvantages of this scheme is that special-made insulators require more research and development funds and time; the second disadvantage is that this scheme cannot be applied to insulators and stock insulators that have been operating on the grid, and cannot be used for these insulators with a large number of traditional shapes. Retrofit; the third disadvantage is that the creepage distance of the umbrella plate with a flat surface is relatively short, which is not as long as that of the umbrella plate with umbrella edges on the lower surface of the umbrella plate.

Embodiment Construction

[0024] In accompanying drawing 1, iron cap 1, steel foot 2, umbrella dish 3 and adhesive packing material 4 have formed a single-layer umbrella dish shape suspension insulator (9 is locking pin pin mouth) together. The lower surface of the umbrella disk 3 of the suspension insulator has two downwardly protruding annular umbrella edges, that is, an outer umbrella edge 81 and an inner umbrella edge 83 , and a downwardly extending annular drip edge 7 . The structural height (note: this word is technical term) of this suspension insulator is 146 millimeters, and the diameter of umbrella disk 3 is 255 millimeters. The middle hole of synthetic shed 5 extends upwards in a tubular shape, and the top of the tubular extension and the lower surface of the umbrella disc 3 of said suspension insulator are bonded to each other by adhesive 6 (all sides of the ring-shaped umbrella edge are bonded together in the present invention) Both the surface and the lower surface are regarded as part of...

Abstract

This invention is concerned with the technique project that the bottom surface of single-layer umbrella cap and pin insulator of the glass or the porcelain with umbrella arris splices the composed umbrella shed made of the silicon rubber polymers and gets double-layer umbrella-hanging insulator. The structure is: the middle hole of the compound umbrella shed extends upwards by drum shape, the top part of the drum shape and the umbrella cap bottom surface of the hanging insulator splices with each other. The invention can improve the anti fouling of the insulator without reducing its performance in un/installation.

Description

technical field [0001] The invention relates to a disk-shaped suspension insulator made of porcelain or toughened glass, which is used for suspending wires on the pole tower of a power transmission line and plays an insulating role, and a composite shed made of high-molecular materials such as silicon rubber bonded (fixed) thereon . In particular, the present invention relates to the bonding structure between suspension insulators and composite sheds. Background technique [0002] Silicone rubber is an excellent anti-pollution flashover material for external electrical insulation. Bonding the synthetic shed made of silicone rubber to the insulator can not only give full play to the superiority of this material, but also increase the creepage distance of the insulator, thereby greatly improving Increase the pollution flashover voltage of insulators. Announced on September 11, 1991, the patent named "composite insulator" and application number 90227...
