Description
Technical field
The utility model relates to a kind of lightning arrester, particularly the lightning arrester that has insulator function concurrently about using in power transmission and transformation system.
Background technology
Lightning arrester with insulation function is installed on electric power line pole tower, and row utilize its good overvoltage Limiting ability as the zinc oxide leakage conductor, improve the lightning protection level of transmission line, carry industry to adopt in power transformation gradually, and benefit is quite remarkable.Along with a large amount of employings of leakage conductor, the mounting means of lightning arrester on shaft tower becomes the key factor that hinders the further popularization of leakage conductor.Particularly might influence the intensity of shaft tower in the frequent area of coastal typhoon, violent typhoon becomes the hidden danger of accident temporarily.Replace insulator with lightning arrester, simple and convenient except installing, do not influence shaft tower intensity and attractive in appearance outside, bear the pulling force of lead, so at first will solve the tensile load problem of lightning arrester, be again the lightning arrester fault most because poor sealing makes moist gas cut go into and short circuit, also influence promoting the use of of composite insulator lightning arrester.CN1037472C discloses a kind of lightening arrestor insulator and the manufacture method thereof of Japanese firm, and this method is to put into the lightning arrester that zinc oxide valve plate and discharging gap are realized the tape insulation subfunction in porcelain insulator or glass insulator.Therefore, it does not still solve problems such as tension load intensity difference and moistureproof invasion.
Summary of the invention
The purpose of this utility model is at the above-mentioned existing defective of insulator lightning arrester, designs the sub-lightning arrester of a kind of High Performance Insulation, has higher mechanical strength, and good stretch-proof load can and prevent the performances such as infiltration of moisture through the attack of wind and snow.
Design of the present utility model is, the suspended isolator lightning arrester, it comprises the gold utensil at two ends, middle zinc oxide valve plate and more piece umbrella insulating coating, it is characterized in that the ring-type zinc oxide valve plate is nested in mandrel outer in the insulation, and the zinc oxide valve plate laminated bottom is provided with desiccant layer, the top is provided with airproof isolation chamber, and is with insulating sleeve outside airproof isolation chamber, zinc oxide valve plate lamination and desiccant layer, and more piece umbrella overcoat is compounded in the periphery of insulating sleeve.
Compared with prior art, advantage of the present utility model is: tensile strength and the tensile load of having strengthened the insulator lightning arrester, owing to adopt high performance zinc oxide valve plate, middle plug runs through the zinc oxide valve plate lamination, the periphery is overlapped insulating sleeve again, the stress point that makes insulator from zinc oxide valve plate transfer to by glass fiber bundle and silicon rubber form on plug and the insulating sleeve, significantly improved tensile strength, zinc oxide valve plate lamination and insulating sleeve two ends crimping metal fixture, be mechanical connection and the electric connecting member of gold utensil as transmission line, press the zinc oxide valve plate lamination by the compression spring simultaneously, make lightning arrester have bigger tensile load, being provided with of desiccant layer keeps the intermediate cylinder soma dry, stablize the performance of zinc oxide valve plate.Macromolecular materials such as employing silicon rubber are made suspension type, and good anti-pollution and hydrophobicity performance are convenient to apply in the transportion wire road of high-tension high-power.
Description of drawings
Fig. 1 is a structure cutaway view of the present utility model.
Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Insulator lightning arrester shown in Figure 1, also claim the direct hanging type lightning arrester, be more piece umbrella shape or the solid column of skirt shape, its center is plug 2 in the insulation, as the glass fibre plug, ring-type zinc oxide valve plate 8 is nested in middle plug 2 peripheries, form central column, insulating sleeve 9 is linked in the periphery of zinc oxide valve plate lamination, formation is that center, zinc oxide valve plate lamination 8 are intermediate by the glass fibre plug, insulating sleeve 9 is the tough and tensile column of insulating barrier, and this insulating sleeve is formed the fiberglass tubular with glass fibre and silicon rubber.Coated one deck silastic-layer 7 outside the glass fibre plug.The zinc oxide valve plate laminated bottom is a desiccant layer 12, is made up of molecular sieve desiccant box body 13, loam cake 11 and lower cover 14.Airproof isolation chamber 4 is established at zinc oxide valve plate lamination top, in establish conductive strips 5 and compression spring 6, the elastic compression zinc oxide valve plate lamination of compression spring 6 makes and contacts between the zinc oxide valve plate closely, improve the intensity of lightning arrester, also compress isolation pad 19 simultaneously and produce the elastomeric isolation space 4 that forms by insulating sleeve 9 and isolation pad 19.More piece umbrella overcoat 10 is enclosed within the periphery of insulating sleeve (9), the metal fixture of upper and lower flange is adopted in insulating sleeve 9 two ends crimping, and the desiccant layer 12 at plug 2, zinc oxide valve plate lamination and two ends and airproof isolation chamber 4, insulating sleeve 9 are assembled into one with more piece umbrella overcoat 10 in making.Between upper flange 1 and the insulating sleeve 9, sealing ring 3 is established to prevent that drier can keep intermediate cylinder vivo oxidation zinc valve block to be in drying regime, stablizes the performance of lightning arrester in the moisture invasion insulating sleeve in its contact site.
Lightning arrester fault great majority are because zinc oxide valve plate makes moist or poor sealing causes, the isolation ward 4 of the hermetic barrier moisture invasion of establishing except the zinc oxide valve plate top and the drying box of bottom, also air in the lightning arrester is taken out, fill pure nitrogen again and make and keep little positive air pressure in the insulating sleeve, to stop the moisture invasion, therefore in lower flange 15, be provided with by pump bowl 16, sealing plug 17 and sealing ring 18 are formed the moisture seal structure of inflated with nitrogen, make zinc oxide valve plate keep long-term effectively dry, thereby reduce the failure rate of lightning arrester.
