The utility model relates to a kind of device of eliminating thunder and lightning.

In order to defend this natural calamity of being struck by lightning, people are through long-term practice, lightning rod, lightning arrester, lightning conduction have been invented, to preventing that thunderbolt from having obtained positive effect, but it is little that these lightning arresters or facility also exist protective range, require problems such as earth resistance is very little, so thunder-strike phenomenon still constantly takes place.Along with science and technology development, people study and have tested various dissipation arrays in recent years, disappear induced electricity that Thunder God department releases from thunder eliminating device as the U.S., the Chinese patent communique also discloses some dissipation arrays, but disclosed these dissipation arrays generally can only be eliminated direct lightning strike, then (straight to parallel thunder, around shocking as the bottom because of the structure of dissipation array, prevention eliminating needle only points to aerial top or horizontal direction) and the used material electric current that causes dissipating too little, generally have only several milliamperes, thereby can't eliminate thunderbolt fully.Whole dissipation array is if any permeability magnetic material (as common iron), also can make dissipation array produce serious remanent magnetism when eliminating thunderbolt, so just the change in polarity of induction lightening field apace.

The purpose of this utility model provides a kind ofly can eliminate the sudden thunder and lightning of launch aing surprise attack, and can also be at the beginning of thunder and lightning forms just can make building, communication and electric power facility exempt from the harm of thunderbolt according to the intensity of thunder and lightning field with the device that thunder and lightning dissipates in advance.

The utility model is realized in following mode: design the lightening inductor that can respond to the certain limit thunder and lightning field, this inductor is non-magnetic metal frame, is densely covered with many prevention eliminating needles above, and the top of metal frame is an attracting thunder needle.This inductor can attract directly to introduce the earth than the electric charge of the thunder and lightning field of large space scope, also the thunder and lightning that moment can be launch aed surprise attack is introduced the earth by the limiting filter safety of the design people's design, the structural principle of this limiting filter is seen the Chinese patent utility model CN:91216547.2 " transmission line dissipation array " that the applicant applies for, it forms pi type filter by inductance coil and electric capacity, the winding of inductance coil is connected on respectively on the electric current downlead and iron tower of metal frame, capacitor is to constitute by wrapping in three outer metallic plates of inductance, wrap in the interior metallic plate that is of nexine, the centre is a grounding plate, outermost layer is outer metallic plate, interior metallic plate is provided with the fixed electrode pin, outer metallic plate has the adjustable electrode pin, the common grounding plate that points to, grounding plate is connected with the earth.When thunder and lightning hits on attracting thunder needle, powerful electric current moment is added on the inductance, its inductance coil will stop its variation, the electric capacity that forms between simultaneously inside and outside metallic plate and the grounding plate is with thunder and lightning conducting ground connection, the electrode needle of establishing on the metallic plate plays the effect of adjusting striking voltage, in the time of making dissipation array be subjected to thundercloud electric field induction generation high-tension electricity or chance thunderbolt generation high-tension electricity on every side again, electrode needle produces sparkover over the ground.

The reason that the utility model can dissipate thunder and lightning field in advance is that thundercloud charge induces the charges of different polarity on prevention eliminating needle when the cloud layer that has electric charge is sailed in the sky of lightening inductor, and in discharging and thundercloud charge.Mobile this direction charge density that makes of electric charge reaches maximum, thundercloud electric field strength direction is just pointed to prevention eliminating needle, like this than many prevention eliminating needles on the small size metal frame just can with around the larger area lightning induction come, and promptly do not dissipate reaching the thunder and lightning lotus of launch aing surprise attack in 500 meters of the radiuses.And for the oncoming force swift and violent launch a surprise attack thunder and lightning when attacking, the attracting thunder needle that is installed on the metal frame at first is struck by lightning, powerful electric current will be stoped its variation by the inductance coil of limiting filter, and by electric capacity with thunder and lightning conducting ground connection.

Below in conjunction with description of drawings enforcement structure of the present utility model:
