Abstract
The utility model relates to a gapless zinc oxide arrester with an insulating wire and a composite casing, which is characterized by comprising a wiring body, a sealed cap, an arrester main body and a heat shrinkable sleeve, wherein the sealed cap and the arrestor main body form an integral structure through molding in high temperature, the sealed cap and the wiring body are connected through a screw, and the heat shrinkable sleeve is mounted on the combing portion of the sealed cap and the wiring body. The utility model has the advantages that one segment of cable wire is led out, which is convenient for front-line electric workmen to operate on site, and the gapless zinc oxide arrester guarantees excellent sealing property and insulated durability of the sealed cap and the insulated wire under the circumstance that the arrestor normally works, and outer-insulating power frequency pressure resistance reaches the national standard. The utility model has the advantages of low production cost of products, simple and aesthetic structure and strong practicability.
Description
Technical field
The utility model is a tape insulation lead composite sheath zero-clearance zinc oxide lightning arrester, belongs to electrical network shocking preventing technology field.
Background technology
Thunder and lightning is a kind of weather phenomenon that often occurs summer, and the thunder calamity constitutes huge threat to natural resources and the human material progress of creating.At first thunder and lightning produces scorching hot high temperature, also has lightning induction in addition, and lightning induction comprises electrostatic induction and electromagnetic induction, and it can produce the induction high voltage.Thunder and lightning generally is divided into 3 kinds for the mankind's harm: direct lightning strike, lightning wave are invaded and indirect lightning strike.Direct lightning strike is meant that thunder and lightning directly hits building, trees, the earth, lightning protection device or human body, and the direct stroke acousto-optic is concurrent, and is aggressive, and old children all knows; Lightning wave is invaded and is meant thunder and lightning to overhead transmission line and metal pipe line effect, and lightning wave may be invaded within doors along these pipelines, jeopardizes personal safety or damage equipment; And indirect lightning strike takes place silently, is difficult for discovering, and consequence is serious, and the object that direct stroke and indirect lightning strike destroy is different, and direct lightning strike mainly break building, power transmission line on the discharge path hit and extremely wound people and animals etc., and the induction thunder mainly destroys electronic equipment.Thunder and lightning also can cause forest fire, and the annual damage to property that is caused is up to many hundred million dollars.Thunder and lightning can injure human life, and its that powerful electric current can make human heart and respiratory system pause and die.Thunder and lightning also is the one of the main reasons of power breakdown, because its that precipitate powerful electric power can burn transformer.The major function of lightning arrester is the development of restriction lightning overvoltage and switching overvoltage, and the energy that these overvoltage produce is released into ground by it, has so just avoided power equipment to suffer these superpotential invasion and attack.Lightning arrester is connected between live wire and the ground usually, and is in parallel with protected equipment.When overvoltage value reached specified action voltage, lightning arrester moved immediately, flow through electric charge, and the over-voltage amplitude is protected apparatus insulated; After magnitude of voltage was normal, lightning arrester restored to the original state rapidly again, to guarantee system's normal power supply.In order to guarantee the lightning arrester operate as normal, must guarantee the good insulation tolerance performance and the sealing property of sealing cap and wiring body and lightning arrester main body, the external insulation industrial frequency withstand voltage reaches GB; Existing product can not be accomplished.
Summary of the invention
The utility model proposes a kind of tape insulation lead composite sheath zero-clearance zinc oxide lightning arrester, be intended under the situation of lightning arrester operate as normal, guarantee the good insulation tolerance performance and the sealing property of sealing cap and wiring body and lightning arrester main body, thereby make the external insulation industrial frequency withstand voltage reach GB.
Technical solution of the present utility model: it is characterized in that comprising the wiring body, sealing cap, the lightning arrester main body, heat-shrinkable T bush, wherein sealing cap and lightning arrester main body form integral structure by hot press moulding, thread connection between sealing cap and wiring body, heat-shrinkable T bush is contained in the binding site of sealing cap and wiring body.
Advantage of the present utility model: under the situation of lightning arrester operate as normal, guarantee the good seal performance and the insulation tolerance energy of sealing cap and wiring body and lightning arrester main body, thereby make the external insulation industrial frequency withstand voltage reach GB.Product cost is low, simple in structure, attractive in appearance, practical.
Description of drawings
Accompanying drawing 1 is the structural representation of tape insulation lead composite sheath zero-clearance zinc oxide lightning arrester,
Among the figure 1 is the wiring body, the 2nd, and sealing cap, the 3rd, lightning arrester main body, the 4th, heat-shrinkable T bush.
Embodiment
The contrast accompanying drawing is characterized in that comprising wiring body 1, sealing cap 2, lightning arrester main body 3, heat-shrinkable T bush 4, wherein sealing cap 2 and lightning arrester main body 3 form integral structure by hot press moulding, 1 thread connection of sealing cap 2 and wiring body, heat-shrinkable T bush 4 are contained in the binding site of sealing cap 2 and wiring body 1.
During making, at first mould is loaded onto assist location screw rod M10, then the sizing material monolithic for preparing being put into die cavity reposefully is placed on plug on the sizing material again, and the gap of adjusting setscrew nut and die cavity, again the sizing material uniform and stable be placed on the plug, start vulcanizer, through certain hour, hot press moulding is shaped.Go out to want in the mold process steadily, the parallel minute mould in two ends do not allow the holder of monolateral firmly sled, in case plug is impaired, clears up mould at last, high temperature vulcanized monolithic molding.Realize lightning arrester main body and sealing cap integral structure.The material saving, the upper end is hermetically sealed, and insulation effect is good.
Insulated conductor wiring body adopts the JKRYJ-16 balck cable, manufacture method: the external insulation sleeve of an end of cable being peeled off an end of line with stripping tool 13mm, exposed copper cash is inserted in the slotted eye of stainless steel termination φ 6, the insulating coating of stainless steel termination and cable is adjacent to, with hydraulic tongs cable is fastened, after being pressed onto 90% for the first time during hydraulic pressure, the wiring body revolved to turn 90 degrees again compressing with hydraulic tongs.Check wiring body cable and termination after compressing at last with pulling when supportting, the termination line does not have loosening.
With following end shield upper end cover, the nameplate of lightning arrester main body, on the M10 screw according to drawing status requirement screw on 2 on stainless steel nut, 2 of φ 10 stainless steel gasket.To carry out being placed on upside down on the lightning arrester of sealing negative pressure test and drench assembling wiring body behind solid carbon dioxide part 2h on the workbench.To screw in behind the wiring body insulated part gluing in the lightning arrester main body, after screwing, port in wiring body and lightning arrester main body puts φ 16 * 15mm black fever Heat-Shrinkable Tubings again, guarantee the lightning arrester good seal with the hair dryer pyrocondensation, the circle that the cable of wiring body is rolled into 20mm is oval with holding into, fastens at mid portion with tieing wire knot.
