Abstract
The utility model relates to an end part connecting accessory for a composite insulator used in an electric transmission line. The end part connecting accessory comprises a hanging ring, an insulator end and a hinge shaft, wherein a hinge hole is formed at the left end of the insulator end, the right end of the insulator end takes the shape of a shaft and is used for being fixedly connected with the flexible core end of a composite flexible insulator, the hanging ring is hinged with the insulator end through the hinge shaft, and the hanging ring is hinged with a support. The end part connecting accessory has the advantages of light weight and high intensity, and is suitable for end part connections of the composite insulators and composite flexible insulators with various mechanical load grades.
Description
Technical field
The utility model relates to a kind of end coupling of composite insulator of used for transmission line.
Background technology
The metal-ware of composite insulator claims the end coupling again, is a kind of device that constitutes composite insulator, with the insulating part assembling, connects usefulness as installing, after outer lead or supporter are connected, in order to transmit mechanical load.By the molecular link insulator string of disc suspension porcelain/glass insulation, can rotate mutually and bend between each sheet insulator, help overcoming extruding force.Clavate composite insulator end metal-ware is for being rigidly connected, and whole composite insulator becomes a rigid body, can not rotate and bend, and is difficult to bear extruding force; Its district's bonding strength that is rigidly connected also is difficult to guarantee.
Summary of the invention
In order to overcome the shortcoming of prior art, the utility model provides a kind of end coupling of transmission line composite insulator, and it is in light weight, the intensity height.
The technical scheme in the invention for solving the technical problem is: it comprises link, insulator termination and hinge, the left end of described insulator termination has hinge hole, right-hand member is the axle shape, be used for being connected with the flexible core of composite and flexible insulator end, described link is hinged by hinge and insulator termination, and link and supporter are hinged.
Described link be shaped as U-shaped link, open U-shaped link, dribbling bulb hanging ring or dribbling nest link.
The material of described link and insulator termination is a metal, or high strength fibre, matrix resin or rubber, high strength fibre comprises one or more in polyamide fibre, high tenacity polyester fiber, aramid fiber, superhigh molecular weight polyethylene fibers, basalt fibre, polyphenylene sulfide fibre, thermotropic liquid crystal fiber and the high strength glass fiber.Matrix resin or rubber are one or more in phenolic resins, bimaleimide resin, high-performance epoxy resin, polyimide resin, silicones, silicon rubber, fluorosioloxane rubber, polyurethane rubber and the vinyl rubber.
The utility model compact conformation, in light weight, the intensity height, easy for installation, it is little, reliable to wear and tear, and is suitable for the composite insulator of various mechanical load grades and the end of composite and flexible insulator and is connected.
