Abstract
The present invention discloses an optimized lightning rod which is composed of a base seat, an upper supporting seat, a lower supporting seat, a plurality of impedance chains, a lightning receiving device, a lightning preventing cover, a lightning arresting unit, a radiation oscillator, etc., wherein the lightning receiving device is arranged at the front end of the lightning rod; the lightning preventing cover and a casing are connected by screw bolts through a flange disc on the casing; a wave clipper, an electronic lightning arrester, a lightning recorder and a warning device are arranged in the lightning arresting unit. A reciprocal impedance network is artificially arranged between the lightning receiving device and the earth to greatly suppress or reduce ascending (sensing) lightning current and descending (directly attacking) lightning current. Thereby, tall buildings and electronic apparatuses which are easy to damage by the overvoltage of sensing lightning are protected against the damage of lightning current.
Description
The present invention relates to a kind of lightning rod.
Behind Franklin invention lightning rod in 1749, passed through the development in century more than two, lightning rod has obtained using widely, and has played certain lightning protection function really.But a large amount of practice and further studies have shown that, lightning rod not only has bigger limitation, and surprising side effect arranged, that is exactly the secondary thunderbolt effect that lightning rod produces in the process of guiding thunder and lightning inflow place, and this effect (promptly responding to thunder) causes the electronic equipment in the magnetic field that is in induction to suffer that thunder and lightning damages.
In recent years; existing a lot of countries and regions adopt lightning conducter, lighting proof strip, faraday's net, Faraday cage, power ball pin, radioactivity pin, high impulse pin, many hour hands dissipation array or the like to replace lightning rod; their protection philosophy is the same with lightning rod, all is to utilize " drawing thunder " effect of towering grounded metal lightning-arrest.But they all fail to break away from the weakness that conductor draws thunder, thereby can not overcome the problem the same with lightning rod eventually.
From the fifties, domestic since the seventies abroad, various dissipation arrays begin to come out.Dissipation array and lightning rod all should have the effect of " thunder disappears " and " drawing thunder " two aspects simultaneously, and just the effect of contradiction both sides aspect which is comparatively outstanding under different condition.Practice for many years shows that various dissipation arrays still can suffer to attack directly thunderbolt.Therefore, in lightening protection engineering, should be based on studying the effective ways that when dissipation array is attacked directly thunderbolt, reduce indirect lightning strike as far as possible to electronic equipment and inflammable and explosive substances.
For these reasons, the objective of the invention is to design a kind of lightning rod of function admirable, the lightning protection function of existing lightning rod, the effect of dredging of lightning rod is arranged again, make lightning rod itself play powerful decay and gradual effect to lightning current, earth potential counterattack effect when reducing indirect lightning strike effect around the needle body downlead and thunder and lightning inflow place to greatest extent, thus make it can play the lightning protection lightning protection function, can overcome the various limitation and the drawback of conventional lightning conductor again.
The present invention has reached above-mentioned purpose of design with its particular structure, it is by pedestal, axle, the impedance chain, upper bracket, arrester, the anti-cover that dodges, mounting panel, lightning-arrest unit, radiating doublet and undersetting constitute, the impedance chain has three joints at least, every joint is by non-metal shell, lining, impedance body constitutes, impedance body is again by pipe, on, bottom end cover and impedance liquid constitute, impedance liquid is loaded in the pipe, the upper and lower side of pipe is stamped connector, the impedance liquid and the external world are conducted, the anti-cover that dodges is nonmetallic taper type hollow cap, be installed between the impedance chain, top will be covered with impedance chain shell fastening by ring flange and bolt, bottom and mounting panel tighten together, each impedance chain is connected with each other with this structure, the lightning rod topmost anti-cover top of dodging is installed bearing, arrester is vertically mounted in the upper bracket, lightning-arrest unit is arranged in a bottom anti-cover that dodges, peak clipper and electronics lightning arrester have been installed in it, should there be undersetting to be fastened on the axle below the mounting panel of anti-sudden strain of a muscle cover bottom, radiating doublet is installed in the screwed hole of undersetting, and the installation of whole lightning rod should keep arrester by the impedance body in connector and each impedance chain, lightning arrester, axle and pedestal conduct.
Optimized lightning rod is that the people is for being provided with a lightning protection impedance between arrester and the earth, and this impedance network is a reciprocal network, the attenuation coefficient of two rightabout electric currents from top to bottom or is from bottom to top equated, and be a constant.
Statistics shows, building on high-rise iron tower, towering ancient tower, skyscraper, the high mountain etc., upwards the percentage of the shared thunder and lightning sum of up thunder and lightning of development is higher from bottom to top, be generally 70～80%, this optimized lightning rod has the obvious suppression effect to the upward leader electric current, therefore, can greatly reduce thunderbolt sum on high-rise iron tower, towering ancient tower, skyscraper and the mountain building.When top-down direct attack thunderbolt Yushan Hill rock, stone forest, sandy soil or desert, tend to significantly reduce the number of times and the intensity of main discharge, this is because the existence of the big resistance between mountain rock etc. and the earth, be difficult in the extremely short time, supply with the necessary main discharge current of the descending guide's electric charge of neutralization, thereby discharge process slowly can only occur.This optimization lightning arrester is promptly according to this principle, one lightning protection impedance is set between arrester and the earth, when optimized lightning rod being struck by lightning even main discharge has taken place, lightning protection impedance in its main discharge passage can make main discharge current obtain very big decay, make the main discharge time extend to Millisecond, reduce the amplitude and the steepness of main discharge effectively from the microsecond level.
From the above; because the design of this optimized lightning rod science and novel structure; make it have very big attenuation to descending direct lightning strike electric current; and up induction lightening stream had great inhibitory action, thereby protect the most tender and lovely electronics settings such as high-rise structures and the electronic computer that very easily damages, program-controlled telephone, wireless carrier machine not damaged effectively by thunder and lightning for the induction lightening overvoltage.
Further specify the present invention below in conjunction with accompanying drawing.
