Abstract
The utility model relates to a synthetic insulating zinc oxide non-clearance arrester used for the transmission line of AC and DC, which can provide protection for line equipment when the line equipment is subjected with lightning strike. The utility model is characterized in that the external wall of a zinc oxide valve sheet is provided with a winding layer of fiber thermosetting material and an external insulating sleeve of an unequal diameter umbrella skirt made of synthetic rubber. The utility model has the advantages of good sealing performance, aging resistance, explosion proof, antipollution, small size, light weight, convenient installation, etc.
Description
The utility model relates to a kind of AC that is used for, and line facility is provided the lightning arrester of protection when being struck by lightning.
At present; when transmission line is struck by lightning; the equipment lightning protection provides by insulator isolation valve formula or the gapped lightning arrester of zinc oxide; because insulator is poorly sealed; inner valve block can make moist and set off an explosion; the gap of gapped lightning arrester can change in time, thereby causes that operation voltage changes, and influence is used and the life-span.
The purpose of this utility model provides a kind of hermetically sealed zinc oxide arrester without gaps that adopts synthetic rubber as external insulation, with the explosion accident of avoiding making moist and causing because of zinc oxide valve plate, guarantees that electric power system normally moves when thunderbolt.
The utility model is realized as follows; Grade according to working voltage, selected zinc oxide valve plate number, all use the high-strength conductive adhesive bonding the metal terminal between zinc oxide valve plate and two ends, after its outer wall adopted the fiber thermosets to twine also hot pressing, will having not, the synthetic rubber external insulation sleeve integral die of isometrical full skirt formed.
The utility model with there being technology to compare, external insulation adopts the not synthetic rubber cover of isometrical full skirt, it is reliable to have a sealing, ageing-resistant performance, not isometrical full skirt has prolonged the pollution flashover distance and has prevented the clog snow in winter and the external insulation short circuit that spring and summer, heavy rain caused.Adopt the fiber thermosets to twine to improve the stiffness and the tensile property of lightning arrester.Radome plays all pressure effects.That this lightning arrester has is explosion-proof, resistant, miniaturization, lightweight, advantage such as easy for installation.
Fig. 1 provides a most preferred embodiment of the present utility model, by the elaboration to this embodiment, provides details of the present utility model.
In Fig. 1, (1) is connection bolt, and (2) are nut, rises to install and fix and the wiring double action, and (3) are radome, are fixed on the two ends of synthetic rubber external insulation sleeve, to improve the Electric Field Distribution of end.Between the zinc oxide valve plate (6), use high-strength conductive adhesive such as conductive epoxy glue, bonding (9) such as conductive polyester glue between zinc oxide valve plate and the aluminium terminal (5).Its outer wall fiber thermosets, as epoxy resin impregnated alkali-free glass wool cloth, writhing number layer and heat pressure adhesives (7) such as polyamide heat pressure adhesive cloth, deliver in the unitary mould, with not isometrical full skirt synthetic rubber cover, make compression molding (4) as silicon rubber or ethylene-propylene rubber, after sulfuration, install bolt, radome, nut.One spill seepage-proof trough (8) is arranged on metal terminal (5).
When circuit suffered the lightning wave invasion and attack, lightning current flow through metal terminal through lead-in wire, and adhesive linkage, valve block, lower terminal and bolt discharge through earth connection again.And when normal operation, be high-impedance state and the characteristics of being failure to actuate, thereby provide protection to line facility.
Claims (2)
1, a kind of composite insulation zinc oxide arrester without gaps comprises zinc oxide valve plate, it is characterized in that the not isometrical full skirt external insulation sleeve that the zinc oxide valve plate outer wall has fiber thermosets winding layer and synthetic rubber to make.
2, composite insulation zinc oxide arrester without gaps as claimed in claim 1 is characterized in that having on the metal terminal spill seepage-proof trough.
