Abstract
A column-type insulator comprises an insulator with an umbrella skirt, and metal base seats, the metal base seats are arranged at two ends of the insulator and are pasted together through cement glue. Threaded assembling holes are arranged in the metal base seat, the insulator is a solid, and gaskets are arranged among central positions of two ends of the insulator and the metal base seats. The column-type insulator is simple in structure and long in service life.
Description
Technical field
The present invention relates to a kind of insulator, especially refer to a kind of pillar insulator.
Background technology
Pillar insulator is a kind of special insulation control, can play an important role in overhead transmission line.Now, pillar insulator slowly develops for high type high-tension bus-bar connection tower, can increase creepage distance.Pillar insulator plays two basic roles in overhead transmission line, it is support wire and prevent that electric current from going back to ground, these two effects must be guaranteed, insulator should be owing to environment and the electric loading condition various dynamo-electric stress that causes that changes lost efficacy, otherwise insulator will lose efficacy, and will damage use and the service life of whole piece circuit.Existing pillar insulator main body generally is the hollow insulator with cluster parachute, and insulator is connected with metab in two ends up and down, and metab has embedded Screw assembly hole, adopts cementing together between insulator and the metab.Existing pillar insulator project organization is simple, easy to use, and is still because porcelain insulator is hollow, breakdown easily during use, and then affects the normal use of whole circuit.In addition, because adopt cementing together between insulator and the metab, because exterior temperature change, so that insulator cracks because of the stress that expands or shrink easily, so that shorten the useful life of insulator, be unfavorable for the stable operation of circuit.The Chinese patent Granted publication number is CN201638616U, Granted publication day, the utility model patent for 2010.11.17 provided a kind of post insulator, it comprise insulator, cast iron seat and be arranged on insulator and cast iron seat between the cement inserts, the insulator boss that described insulator has the insulation daughter and is located at insulation daughter lower end consists of.Thereby this design improves the stress state of column support type insulator and cast iron seat junction by the profile that changes the insulator binding site, avoids forming cast iron seat and arrests tight and make insulator crackle occur, has prolonged the useful life of insulator.Although this design has solved the problem that crackle appears in insulator easily, whole insulator remains hollow-core construction, still exist breakdown hidden danger.In addition, although the variation of this design by structure so that the stress between insulator and the cast iron seat improves, under the variation of temperature, both still exist by direct stress, between do not have the stress buffer parts, crackle still appears in insulator easily.
Summary of the invention
The objective of the invention is to overcome the pillar insulator that exists in the prior art easily breakdown, the problem of crackle appears easily, a kind of pillar insulator of simple in structure, long service life is provided.
For realizing above purpose, technical solution of the present invention is: a kind of pillar insulator, comprise insulator, metab with full skirt, described metab is installed in the two ends of insulator, metab is bonded together by cement glue, the Screw assembly hole is arranged on the metab, and described insulator is solid, is provided with pad between center, insulator two ends and the metab.
Described pad is felt paper.
Described cement glue is portland cement.
Compared with prior art, the present invention has following beneficial effect:
1, insulator is solid construction among the present invention, so that whole insulator is not easy is breakdown, uses more reliable.
2, between center, insulator two ends and metab, be provided with pad, pad can be selected felt paper, when variations in temperature causes STRESS VARIATION between metab and the insulator, pad can play a cushioning effect, so that insulator is not easy to occur crackle, whole insulator longer service life.
Description of drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is cutaway view of the present invention.
Among the figure: insulator 1, metab 2, cement glue 3, Screw assembly hole 4, pad 5.
Embodiment
The present invention is further detailed explanation below in conjunction with Fig. 1 and Fig. 2:
Referring to Fig. 1 and Fig. 2, a kind of pillar insulator, comprise insulator 1, metab 2 with full skirt, described metab 2 is installed in the two ends of insulator 1, metab 2 is bonded together by cement glue 3, Screw assembly hole 4 is arranged on the metab 2, and described insulator 1 is solid, is provided with pad 5 between insulator center, 1 two ends and the metab 2.
Described pad 5 is felt paper.
Described cement glue 3 is portland cement.
In daily use, screw in Screw assembly hole 4 with bolt, in order to metab 2 is fixed on the electric wire, thereby pillar insulator is linked to each other with electric wire.Because insulator 1 is solid construction among the present invention, so that whole insulator is not easy is breakdown, use more reliable.In addition, between insulator center, 1 two ends and metab 2, be provided with pad 5, pad 5 can be selected felt paper, when variations in temperature causes STRESS VARIATION between metab 2 and the insulator 1, pad 5 is to play a cushioning effect, so that insulator 1 is not easy to occur crackle, whole insulator longer service life.Simple in structure, the long service life of the present invention.
