Description
Technical field
The utility model relates to Lightning Prevention Technique field, particularly relates to a kind of electric eliminating lotus lightning rod.
Background technology
Thunderbolt is one of people's ten kinds of natural calamities the most serious of generally acknowledging, the disaster accident caused that is struck by lightning happens occasionally, and thunderbolt causes building damage, loss of life or personal injury, causes fire explosion, and the moment endangers the safety of people's lives and properties, therefore, how effectively to avoid the infringement of thunderbolt very important.
At present, for the harm that thunderbolt produces, the arresters such as lightning rod, lightning conducter, lightning conduction are installed in the measure generally taked, and carry out connecing sudden strain of a muscle, then lightning current are caused the earth, avoid the hazardous accidents that the facilities such as thunderbolt building cause.The general principle of lightning arrester is: thundercloud charged is in the air responded to due to electrostatic induction and produced the electric charge contrary with charge polarity in thundercloud on the object on ground, along with space thundercloud produces the enhancing of electric field, thundercloud produces downward descending leader over the ground, on ground, object then can produce upward leader upwards, when the spacing of upward leader and descending leader is enough little, then can be struck by lightning.On the basis of conventional lightning conductor, the international lightning intrusion of Univ Florida USA and test center director professor Rakov propose the concept of pre-arcing lightning rod.
Figure 1A and Figure 1B is the fundamental diagram of prior art pre-arcing lightning rod.Please refer to Figure 1A and Figure 1B, it is inner that d ' gap is positioned at pre-arcing electronic trigger lug (passive electronics triggers loop).D gap is made up of needle body upper electrode and pre-arcing electronic trigger lug shell.Upper electrode when upward leader is discharged, for upwards producing spark.
Below introduce the operation principle of prior art pre-arcing lightning rod.As shown in Figure 1A, during without thunder and lightning cloud, the electric field strength E in air is about 300V/m.As shown in Figure 1B, when having thunder and lightning cloud, when the electric field strength E between thundercloud and ground is 10kV/m ~ 20kV/m, absorb the energy of space electric field by bottom electrode and charge storage is inner at pre-arcing electronic trigger lug.Charge charging to a certain extent time, discharged by its upper electrode (d gap breakdown), needle body top and tip form strong corona discharge (sheath) around, produce a head-on guide upwards launched in advance, descending leader discharge channel is distorted.Up head-on guide is rapidly to descending leader direction and propagates and catch thunder and lightning; make the d ' gap breakdown of pre-arcing electronic trigger lug; form main discharge passage; lightning current is released into ground by main discharge passage with thunderous along with lightning, thus avoids the protected object around pre-arcing lightning rod to be struck by lightning.
Pre-arcing lightning rod compared to ordinary lightning rod when same place sustained height is installed, launch in advance with just the up head-on guide that descending trapezoidal guide is connected, this up head-on guide launched in advance can advance longer distance, and then more effectively can catch lightning current, thus building is avoided to be struck by lightning.
But China Electronics learns expert and explicitly points out from theoretical research: the effectively ionized function of application high frequency intense radiation electromagnetic wave is the golden key solving thunder calamity problem.Must emphasize, existing pre-arcing mode is exactly a ready-made practical proof, when thunderbolt is arrived, have high frequency to excite by force, then, causes again the effectively ionized function had under high frequency state, punctures air in advance and just obtain the effect of meeting pre-arcing.
