Abstract
The utility model relates to a novel lightning arrester which is used for electric transmission lines and which provides lightning-proof protection for lines and equipment. The utility model has the structure that cylindrical form metallic conductors are arranged on both ends of a valve plate of zinc oxide; a wiring screw bolt is arranged on the metallic conductor; the outer surface of the wiring screw bolt is coated with an external insulating layer which is made from thermosetting resin and which is provided with umbrella skirts with unequal diameter; both ends of the wiring screw bolt are provided with a shielding cover and a nut. The thermosetting resin adopt the technology of once integral moulding by casting, and thus the utility model has the advantages of simple and rapid producing process, low cost, favorable insulating performance, mechanical performance and climate-resistance performance, etc.
Description
The utility model relates to a kind of transmission line that is used for, and protection circuit and equipment are avoided the lightning arrester of effects of lightning.
At present, the zinc oxide arrester of using on the transmission line, its external insulation is made by pottery or tartan.Ceramic insulation is subjected to atmospheric temperature because of poorly sealed, and the influence that humidity changes produces cell breath, easily causes serious accidents such as Explosion of on Arrester, and the ceramic insulation big and heave.The synthetic rubber insulating oxide zinc lightning arrester that developed recently gets up, its insulating surface easily accumulates dunghill, and bad mechanical strength, needs to twine insulating material and gains in strength, and causes complex manufacturing technology, and production cost increases.
The purpose of this utility model, it is simple to provide a kind of manufacture craft, low production cost, the integrated casting type insulation resin zinc oxide arrester of energy long-term safety reliability service.
The utility model is realized as follows, after zinc oxide valve plate is made up according to required electric pressure, constitutes external insulation layer with integrated poured thermosetting resin.The cylindrical surface of the metallic conductor at zinc oxide valve plate two ends is a bellows-shaped.
The utility model compared with the prior art owing to adopt once-cast, integral forming technique makes production technology simple, quick, cost is low.Selected thermoset resin material can solidify at normal temperatures, and its mechanical performance and weather-resistant performance are good, cheap.The cylindrical surface of metallic conductor has the seepage-proof trough of bellows-shaped, does not promptly influence cross-sectional flow area, has increased bonding surface area again.So it is simple that this utility model has production technology, cost is low, insulation property, mechanical performance, advantage such as the weather-resistant performance is good.
Accompanying drawing 1 is a profile of the present utility model.
Embodiment of the present utility model: with zinc oxide valve plate 1 according to the combination of required electric pressure after, metallic conductor 2 places its two ends.With high-strength conductive adhesive such as conductive epoxy glue, conductive polyester glue etc. are bonding between valve block.Connection bolt 3 is installed on the metallic conductor.Be placed in the particular manufacturing craft, pour into a mould thermosetting resin at normal temperatures and pressures, thermosetting resin can be selected unsaturated-resins such as epoxy resin or vinylite for use, makes to have the not external insulation 4 of isometrical full skirt.Install radome 5, nut 6 promptly completes.
Claims (2)
1, a kind of integrated casting type insulation resin zinc oxide arrester, comprise zinc oxide valve plate, respectively there is a cylindrical metal conductor (2) at the two ends that it is characterized in that zinc oxide valve plate (1), connection bolt (3) is installed on the metallic conductor, in its outer surface apposition the not external insulation layer of isometrical full skirt (4) that has that thermosetting resin makes is arranged, and radome (5), nut (6) be housed at two ends.
2, integrated casting type insulation resin zinc oxide arrester as claimed in claim 1, the face of cylinder that it is characterized in that metallic conductor is a bellows-shaped.
