Background technology
Thundering, blow, raining is weather natural phenomena, has uncertainty, and natural resources and the mankind's material progress is formed to titanic peril, and thunderbolt more very, still, exists a kind of article---lightning arrester that can Lightning proof protection building.
The lightning protection effect of lightning arrester is that it can be guided lightning own into and by, leak into the earth itself safely from protection thing top, at present, progressively development along with China's lightning arrester cause, traditional lightning arrester gradually oxidized zinc lightning arrester replaces, because the electric current that zinc oxide can pass through when the normal working voltage is few, when overvoltage effect, resistance sharply declines, the superpotential energy of releasing, reach the effect of protection, the core of zinc oxide arrester is resistor disc, and in order to strengthen the dielectric strength of resistor-piece side, at resistor-piece side, applied the organic coating with high-insulativity, nowadays, the resistor disc of tradition lightning arrester mostly by netted without latitude band wound and solidified resistor disc, tradition lightning arrester exists sealing poor, counter-bending ability a little less than, plasticity a little less than, thermal shock resistance and poor insulativity.
Utility model content
The deficiency existing for prior art, the purpose of this utility model is to provide the zinc oxide arrester that a kind of good seal performance, counter-bending ability are strong, strengthen plasticity, thermal shock resistance and good insulating.
For achieving the above object, the utility model provides following technical scheme: a kind of zinc oxide arrester, comprise lightning arrester body and cluster parachute sheath, described cluster parachute sheath is gapless to be enclosed within on described lightning arrester body, described lightning arrester body comprises insulating support rod and zinc oxide resistance sheet, on described insulating support rod, lower two ends are respectively equipped with top electrode, bottom electrode, described top electrode is connected with connection bolt, described bottom electrode is connected with lower connection bolt, between described top electrode and described upper connection bolt and between described bottom electrode and described lower connection bolt, be equipped with sealing ring, described zinc oxide resistance sheet surface is provided with the cured layer that epoxy powder resin forms.
By adopting technique scheme, epoxy powder resin is a kind of electric insulation polymerizing resin compound, it is a kind of electric insulation coating powder, it is the fire-retardant from putting out epoxy powder resin and having higher mechanical performance of a kind of middle low-temperature setting, to various capacitors, the best moisture protection coating of the electronic component such as varistor and fixed inductance, the zinc oxide arrester of employing epoxy powder resin solidification layer is compared traditional lightning arrester and is had better sealing property, counter-bending ability, plasticity, thermal shock resistance and insulation property, stability and the reliability of zinc oxide arrester have been improved.
The utility model is preferably set to: described insulating support rod sidewall has several draw-in grooves arranging for described zinc oxide resistance sheet.
By adopting technique scheme, draw-in groove the recovery utilization rate that has increased lightning arrester is set, can or increase or reduce zinc oxide resistance sheet, the zinc oxide arrester of safety, convenient, simple recoverable, more environmental protection according to the different of voltage strength intensity simultaneously.
The utility model is preferably set to: described cluster parachute sheath comprises cluster parachute, by silicon rubber integrated injection, is pressed into, and described cluster parachute is that fairshaped discoid body and small one and large one are spaced successively.
By adopting technique scheme, good high temperature resistant, the corrosion-resistant and hydrophobicity that material has, be convenient to zinc oxide arrester in the face of the bad border of various complexity, the setting of cluster parachute is that zinc oxide arrester increases its creepage distance when overvoltage, is convenient to sooner electric current be imported underground.
This practicality is further set to: the diameter of described upper connection bolt and described lower connection bolt is M12.
By adopting technique scheme, the diameter of bolt is that M12 is very conventional, is conducive to zinc oxide arrester and changes.
This practicality is further set to again: described draw-in groove and described insulating support rod are one-body molded.
By adopting technique scheme, reduce the installation cost bringing because of not corresponding slot, zinc oxide arrester is more standardized.
