At present, two insulators that link together on the high-voltage fence are to be " V " type to hang from above, the link of two insulators has bulb gold utensil and steamed bread of corn gold utensil respectively, the bulb gold utensil is embedded in the steamed bread of corn gold utensil, and the steamed bread of corn gold utensil rotation relatively of bulb gold utensil, thereby the lower end of two insulators is linked together.But the snap-in force between bulb gold utensil and the steamed bread of corn gold utensil is not strong, perhaps move a period of time after, perhaps under the high wind effect, the bulb gold utensil spins off from steamed bread of corn gold utensil easily, and the string phenomenon appears falling in insulator, have a strong impact on the normal operation of electrical network, increase the maintenance work of electrical network.
The utility model content:
The purpose of this utility model is to provide a kind of anti-lost string with ring-ring-like extra-high voltage direct-current composite insulator at the deficiencies in the prior art, it has the favorable mechanical performance, and is safe and reliable, has solved the problem that string appears falling in the insulator on the electrical network.
For achieving the above object, the utility model is achieved through the following technical solutions:
Anti-lost string comprises the composite insulator main body with ring-ring-like extra-high voltage direct-current composite insulator, the two ends of composite insulator main body or wherein an end be connected with link.
The front end of link is U type ring or O type ring.
The composite insulator main body comprises high-temperature silicon disulfide rubber umbrella sheath, epoxy resin fiberglass rod and drainage type grading ring, the high-temperature silicon disulfide rubber umbrella sheath is located in the centre position of epoxy resin fiberglass rod, and the two ends of epoxy resin fiberglass rod are fixed with the drainage type grading ring respectively.
The rear end of link is a connector, and the end of connector has the gold utensil end, and the connector central part is emptied and is that cavity, the plug on the composite insulator main body are plugged in the cavity of connector, and the gold utensil end is in being embedded in full skirt.
The beneficial effects of the utility model: the utility model comprises the composite insulator main body, the two ends of composite insulator main body or wherein an end be connected with link; In use, anti-lost string is cascaded by link with ring-ring-like extra-high voltage direct-current composite insulator, the utlity model has the favorable mechanical performance, and is safe and reliable, solved the problem that string appears falling in the insulator on the electrical network.

Embodiment:
Embodiment one
Anti-lost string is seen accompanying drawing 1 to 4 with ring-ring-like extra-high voltage direct-current composite insulator, comprises composite insulator main body 1, and the two ends of composite insulator main body 1 are connected with link 2.Anti-lost string with ring-ring-like extra-high voltage direct-current composite insulator is ± 800kV direct current composite rod insulator series of products, it is designed for rated voltage is the extra high voltage direct current transmission line of 160～550kN for ± 800kV, specified mechanical stretching load, it connects pattern and is the connection of ring-ring, dangles or strain insulator on ± 800kV extra high voltage line.
Wherein, composite insulator main body 1 comprises high-temperature silicon disulfide rubber umbrella sheath 3 and epoxy resin fiberglass rod 4, and high-temperature silicon disulfide rubber umbrella sheath 3 is located in the centre position of epoxy resin fiberglass rod 4.
Point out that further the front end of described link 2 is U type ring or O type ring.The rear end of link 2 is a connector 6, the end of connector 6 has gold utensil end 7, connector 6 central parts are emptied and are that cavity, the plug on the composite insulator main body 1 are plugged in the cavity of connector 6, and gold utensil end 7 is embedded in the full skirt of high-temperature silicon disulfide rubber umbrella sheath 3.
Anti-lost string can run in the high electrical network of electric pressure with ring-ring-like extra-high voltage direct-current composite insulator, face the geographical environment for use of complicated meteorologies such as heavy pollution, high height above sea level, icing, it still has the favorable mechanical performance, stable, safe and reliable, solved the problem that string appears falling in insulator on the electrical network.
