Embodiment
Below in conjunction with accompanying drawing, be described in more detail with other technical characterictic and advantage the present invention is above-mentioned.
The invention provides a kind of method of electric charge lightning guidance, the step of realization is:
A. obtain the size and the polarity of thunderbolt electric charge in the atmospheric electric field;
B. the thunder conductor is carried and the electric charge of thunderbolt opposite polarity to drawing, and strengthens and draws thunder conductor 1 surface field intensity;
C. after thunder conductor 1 was drawn in thunderbolt, the electric current that thunderbolt is produced released from drawing thunder conductor 1.
The described thunder conductor that draws is general electric conducting material.
According to this method, we can design the corresponding charge thunder carrying-off device, see also Fig. 1, shown in Figure 2, and it is the functional structure sketch of electric charge lightning guidance device of the present invention preferred embodiment one and preferred embodiment two,
First kind of its component units of device comprises: draw thunder conductor 1, high-pressure delivery unit 5 and earial drainage device 6, wherein,
The described thunder conductor 1 that draws is arranged at the top of protected object, also can be directly with the part at protected object top as drawing thunder conductor 1;
See also shown in Figure 3, it is for the sectional view of electric charge lightning guidance device high-voltage transmission of the present invention unit, described high-pressure delivery unit 5, its structure is to cover a layer insulating 51 on the thunder conductor 1 in described drawing, on insulating barrier 51, covering one deck conductive layer 52, like this conductive layer 52 with draw thunder conductor 1 and constitute electric capacity, just flow to this conductive layer 52 with the electric charge of thunderbolt opposite polarity;
Described earial drainage device 6, be to draw thunder conductor 1 after thunderbolt, electric current on the conductor is discharged to big ground, described earial drainage device 6 comprises suitable earth electrode, and discharging gap between conductive layer and earth electrode or lightning arrester, it can be an earth connection, also can be the metallic conductor of certain depth of being driven underground, for the environment of geology densification, also can be the metallic conduction plate that is tiled in certain area on the face of land;
It has multiple combined method, can be two groups and draw thunder conductor 1, cooperates two groups high-pressure delivery unit 5, constitutes this device (seeing also shown in Figure 1) by two groups of earial drainage devices 6, also can form (seeing also shown in Figure 2) by one group of earial drainage device 6; Draw at one during work and export positive charge on the thunder conductor 1 always, another draws exports negative electrical charge always on the thunder conductor 1, therefore needn't prejudge the polarity of thunderbolt electric charge in the atmospheric electric field, there is one to draw thunder conductor 1 and can be struck by lightning eventually, and lets out the earth by described earial drainage device 6 electric current that produces that will be struck by lightning.
Certainly it can also realize above-mentioned electric charge lightning guidance method by the single thunder conductor 1 that draws, see also shown in Figure 3, it is for the functional unit structure diagram of electric charge lightning guidance device of the present invention preferred embodiment three, it comprises: draw thunder conductor 1, lightning monitoring device 2, receiving lines unit 3, control unit 4, high pressure output unit 5 and drain unit 6, wherein
Described lightning monitoring device 2; can be arranged at the top of protected object; be used to monitor the arrival of thunderbolt, obtain to comprise the size of atmospheric electric field thunderbolt electric charge and the thunderbolt monitor signal of polarity, described lightning monitoring device 2 can be atmospheric electric field detector or thunderbolt monitor.
Described receiving lines unit 3 will be transferred to described control unit 4 from the corresponding thunderbolt monitor signal that receives of thunderbolt monitoring device 2;
