Embodiment
Embodiment 1:
Referring to figs. 1 through the active direct lighting stroke protective device (Activelightningprotectiondevice is hereinafter referred to as ALPD) shown in Fig. 3, by metal air electrode 1, special electronic switch 2, metal grading ring 3 and pedestal 4 form, described metal air electrode 1, special electronic switch 2, metal grading ring 3 and pedestal 4 are fixed by the bolt 5 at special electronic switch 2 two ends successively from top to down, described special electronic switch 2 is by ring-plate capacitor 21, cylindrical nonlinear resistance 22 and silicone rubber encapsulates overcoat 23 are formed, described ring-plate capacitor 21 is sleeved on cylindrical nonlinear resistance 22, ring-plate capacitor 21 and cylindrical nonlinear resistance 22 are encapsulated formation integral structure by silicone rubber encapsulates overcoat 23, the two ends up and down that described bolt is separately positioned on cylindrical nonlinear resistance 22 form two electrode outlet lines.
Concrete, described metal air electrode 1 is made up of metal material, and metal air electrode 1 is in hollow mushroom shape.Described metal air electrode 1 appearance is smooth surface, radius of curvature R>=200mm, surface area S>=400cm
2.Described silicone rubber encapsulates overcoat 23 is provided with annular full skirt 24; Voltage >=the 6kV of described special electronic switch 2, maximum through-current capacity is 100KA, and reaction speed is ns level; Described metal grading ring 3 is made up of annulus metal tube 31 and fixture 32; this metal grading ring 3 is fixed on pedestal 4 by fixture 32; this fixture 32 is many is 360 ° of connecting rods be evenly distributed with annulus metal tube 31 central shaft; in order to make to play all pressure effects between metal air electrode 1 and protected object; avoid protected object to suffer the electrostatic shock of metal air electrode 1, the diameter of described metal grading ring 3 is greater than special electronic switch 2 diameter.
The holder that described pedestal 4 is made for metal material, this holder is welded to each other by base 41, fixed leg 42 and reinforcement 43 and forms, described base 41 is flange disk-like structure, fixed leg 42 is positioned on base 41 center, reinforcement 43 annular spread is in fixed leg 42 side, be positioned on base 41, described metal grading ring 3 is fixed on fixed leg 42 by fixture 32.
Conductivity principle figure of the present invention, as shown in Figure 3, metal air electrode 1 is charge collection district; Cylindrical nonlinear resistance 22 is the non-linear rheostat of Rx; Ring-plate capacitor 21 is capacitor C.
The present invention in the application, as shown in Figures 4 to 6:
When having thundercloud the same day in the air, as shown in Figure 4, because thundercloud is with a large amount of electric charges, due to the effect of electrostatic induction, the ground below thundercloud and ground object all bring the electric charge contrary with thundercloud.Atmospheric electric field is undergone mutation, the cylindrical nonlinear resistance 22 (nonlinear resistance Rx) of special electronic switch is in high-impedance state, ring-plate capacitor 21 (capacitor C) starts charging, starts the electric charge in air to be loaded on metal air electrode 1.
Electric field strength enhancing between thundercloud and ground will produce a downward lightning leader when reaching the impedance that can overcome air.As shown in Figure 5, at this moment, the nonlinear resistance 22 (nonlinear resistance Rx) of special electronic switch 2 is in high low-resistance alternating state, ring-plate capacitor 21 (capacitor C) is also in charging and discharging state, and the quantity of electric charge much larger than thunder and lightning descending leader head is remained on metal air electrode 1.
When thunder and lightning descending leader is close to active direct lighting stroke protective device (ALPD); as shown in Figure 6; owing to the metal air electrode 1 of active direct lighting stroke protective device (ALPD) being loaded with a large amount of electric charge identical with thunder and lightning descending leader polarity; the power line of thundercloud electric field in protected scope is made to deviate from metal air electrode 1 all the time; and it is close to repel thunder and lightning descending leader; make the electric field strength above protected object and charge density not reach the numerical value puncturing air, thus blocked and connect sudden strain of a muscle.Effectively prevent from producing in protection zone launch aing surprise attack, make not suffer direct stroke in protection zone.
The invention solves a lot of problems of existing lightning arrester, mainly solve the deficiency of lightning rod four aspects.(1) GB GB50057-2010 " Code for design of lightning protection of buildings " 4.2 requirement, the measure of first kind Lightning Protection Building direct striking thunder prevention, should install independently to connect and dodge bar or built on stilts connecing dodges line or net and independently earthing device.But in actual applications, independent lightning rod is difficult to accomplish real independence, because the various pipelines (water pipe, cable etc.) entering building pass possibly near the earthing device of lightning rod, so when lightning rod thunderbolt, high potential can produce counterattack to neighbouring metal object, subsequently thunder and lightning is introduced in building, cause Lightning Disaster.(2) rely on during lightning rod direct striking thunder prevention and must have qualified earth resistance, when earthing device is made in the area of the high mountain station or soil resistivity very severe, want to reach qualified earth resistance, often invest very huge, and earthing effect is bad, the earth potential counterattack phenomenon caused because earth resistance is defective when being struck by lightning is very serious.(3) movable object is if command car, communication van, radar truck, guided missile truck etc. are owing to being at the volley, cannot ground connection very well, even if conventional lightning rod also cannot be installed, if install simple and easy lightning rod and earth resistance is defective, produce high voltage after being tantamount to draw thunder, all can damage equipment people.(4) be struck by lightning building lightning rod after, can around down conductor system, produce very strong electromagnetic field, this magnetic field produces magnetic induction and damage equipment to contiguous plain conductor.When lightning current leaks into the earthing device of the earth, earth potential also can be made to raise, neighbouring metal pipe line or the earthing device that splits be formed and strikes back, make ground connection Pei split with these put the device damage be connected.Its step voltage can also cause people and get killed.
Embodiment 2:
The technical characterstic of the present embodiment is, described special electronic switch 2 is made up of cylindrical nonlinear resistance and silicone rubber encapsulates overcoat, cylindrical nonlinear resistance 22 is encapsulated formation integral structure by described silicone rubber encapsulates overcoat 23, and the two ends up and down that described bolt is separately positioned on cylindrical nonlinear resistance 22 form two electrode outlet lines.All the other the same embodiments.
