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. transform

Embodiment Construction

[0022] in the attached figure 1 Among them, the iron cap 1, the steel foot 2, the umbrella plate 3 and the adhesive material 4 together form a single-layer umbrella plate-shaped suspension insulator. 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 the lower sur...

Abstract

The invention supplies a technology scheme of the multi-layer (double-layer), umbrella shaped and suspending insulator. The vitric or porcelain single-layer, umbrella shaped and suspending insulator and the silastic on the lower surface of the insulator are connected to form the umbrella skirt. The specific structure is that the middle hole of the umbrella skirt extends upward in the tubular way and the upper of the tubular extending part and the lower surface of the umbrella plate of the suspending insulator are bonded. It reforms the single-layer, umbrella shaped and suspending insulator improves the anti-flashing nature of the insulator and doesn't decrease its installing, detaching and series nature.

Description

technical field [0001] The invention relates to a disk-shaped suspension insulator made of porcelain or toughened glass for suspending wires on a pole tower of a power transmission line for insulation, and a composite shed made of silicon rubber bonded 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. [0003] There are many schemes for bonding silicone rubber composite sheds on porcelain or tempered glass single-layer umbrella disk-shaped suspension insulators, two of whi...
