Detailed description of the invention
Below in conjunction with accompanying drawing, by describing a preferably specific embodiment in detail, the present invention is further elaborated.
As it is shown in figure 1,10KV tension-resistant rod anti-thunder insulator, comprising insulator 10, also comprise arc ring 20 and electric discharge ring 30, insulator 10 one end connects arc ring 20, and the other end connects electric discharge ring 30.
As shown in Figure 2, arc ring 20 comprises two semicircle arc rings, two semicircle arc ring respectively aluminium alloy integral die-cast form, and have stronger mechanical performance, and each semicircle arc ring comprises arc ring bearing shell 21, arc ring spoke 22, striking annulus 23 and the angle of divergence 24；It is connected by arc ring spoke 22 between arc ring bearing shell 21 with striking annulus 23；Striking annulus 23 outer periphery is provided with the angle of divergence 24, and the angle of divergence 24 is in interior splayed, beneficially striking.Arc ring bearing shell 21 is in Ω shape, the one end connecting arc ring spoke 22 is fixed on the outer arc surface of arc ring bearing shell 21, the two ends bossing of arc ring bearing shell 21 is respectively equipped with arc ring screwed hole 211, being provided with arc ring bolt 213 in arc ring screwed hole 211, the inner arcuate surface of the arc ring bearing shell 21 of two semicircle arc rings forms arc ring cavity 212.Arc ring bolt 213 is each passed through the arc ring screwed hole 211 of two semicircle arc rings, is fastenedly connected by the arc ring bearing shell 21 of two semicircle arc rings.
As shown in Figure 1, Figure 3, electric discharge ring 30 comprises two semicircle electric discharge rings, two semicircle electric discharge ring respectively aluminium alloy integral die-cast form, there is stronger mechanical performance, each semicircle electric discharge ring comprises electric discharge annulate shaft watt 31, electric discharge ring spoke 32, electric discharge annulus 33, discharge tip 34 and insulating boot 35, is connected by electric discharge ring spoke 32 between electric discharge annulate shaft watt 31 with electric discharge annulus 33；Electric discharge annulus 33 outer periphery is provided with discharge tip 34, and discharge tip 34, in divergent shape, is beneficial to electric discharge；Insulating boot 35 is arranged on the external diameter of discharge tip 34, there is gap between insulating boot 35 and discharge tip 34, and insulation 35 cover uses silicone rubber to make, and insulating boot 35 is in funnel-form, and surface is provided with multiple button 351, it is simple to install.Electric discharge annulate shaft watt 31 is in Ω shape, the one end connecting electric discharge ring spoke 32 is fixed on the outer arc surface of electric discharge annulate shaft watt 31, the two ends bossing of electric discharge annulate shaft watt 31 is respectively equipped with electric discharge ring screwed hole 311, being provided with electric discharge collar bolt 313 in electric discharge ring screwed hole 311, the inner arcuate surface of the electric discharge annulate shaft watt 31 of two semicircle electric discharge rings forms electric discharge annular space chamber 312.Electric discharge collar bolt 313 is each passed through the electric discharge ring screwed hole 311 of two semicircle electric discharge rings, is fastenedly connected by the electric discharge annulate shaft watt 31 of two semicircle electric discharge rings.
nullInstallation method and specifically application: gold utensil one end, lower end of compound strain insulator is connected with electric pole by bolt，Two semicircle arc rings are enclosed within the other end of gold utensil，Arc ring cavity 212 and lower end gold utensil outer surface compact siro spinning technology，Which increase contact area，Arc ring bearing shell 21 is fastened by arc ring bolt 213，Two semicircle arc rings form an entirety，Ensure that arc ring 20 installs accurate positioning，Fixation，Two semicircle electric discharge ring sets on gold utensil，Electric discharge annular space chamber 312 and upper end gold utensil outer surface compact siro spinning technology，Which increase contact area，By electric discharge collar bolt 313 fastening electric discharge annulate shaft watt 31，Two semicircle electric discharge rings form an entirety，Ensure that electric discharge ring 30 installs accurate positioning，Fixation，So form satisfactory discharging gap between arc ring 20 and electric discharge ring 30.Wrapped up by button 351 with insulating boot 35 on electric discharge ring 30 again, make metal parts need not be directly exposed in air, reached the requirement of insulating.So, when thunder and lightning high electrical breakdown discharging gap, lightning current discharges from discharge tip 34 and carries out discharging rather than original discharging on insulated conductor to arc ring 20, thus solves and make insulated conductor keep away to be troubled by lightning-caused breaking.
In an atmosphere, electric arc is acted on by electromagnetic field, utilizes the interior Figure of eight structure of the angle of divergence 24.The arc root of electric arc is the most outwards drifted about from initial breakdown point, and elongating arc is not integrally fixed at long ablation on a point, thus reduce the damage to arc ring and guarantee that the discharging gap discharged between ring 30 and arc ring 20 remains unchanged, to reach the thunderbolt critical flashover voltage that product is relatively fixed, the Insulation Coordination of built on stilts electrical power trans mission/distribution system is made to meet original design requirement.
Although present disclosure has been made to be discussed in detail by above preferred embodiment, but it should be appreciated that the description above is not considered as limitation of the present invention.After those skilled in the art have read foregoing, multiple amendment and replacement for the present invention all will be apparent from.Therefore, protection scope of the present invention should be limited to the appended claims.
