Compared with prior art, lightning protection system of the present invention and assembly utilize and are arranged in parallel between connector and earthed system by choke and electrical discharger, for controlling the immediate current of electrical discharger, greatly can weaken Lightning Electromagnetic Pulse.A kind of vane of wind energy generator of another the present invention, because arrester is positioned at the top of blade body, its effect utilizes its prominent position exceeding protected object that thunder and lightning is guided into self, accepts direct lightning strike electric discharge, blade therefore can be avoided to be struck by lightning.Thunder and lightning is introduced to arrester, then weakens Lightning Electromagnetic Pulse by lightning-arrest assembly, cuts down the steepness of wave edge of lightning current.
As a kind of lightning protection system of the present invention, lightning-arrest assembly and the improvement of vane of wind energy generator with this lightning protection system, described choke comprises the inductance in parallel with electrical discharger.Resistance due to this inductance is significantly smaller than the resistance of electrical discharger, thunder and lightning major part electric current is made to pass through inductance, the electric energy that inductance stores is produced back-pressure and is discharged by electrical discharger, electrical discharger can be made like this to connect sudden strain of a muscle immediate current and greatly reduce, thus also make the Lightning Electromagnetic Pulse of generation greatly weaken.Described choke also comprises one end and is connected with inductance, the choke ground wire of the other end ground connection.
As a kind of lightning protection system of the present invention, lightning-arrest assembly and the improvement of vane of wind energy generator with this lightning protection system, described electrical discharger comprises at least four electric discharge lamps and two lands, and described electric discharge lamp is arranged between two lands.Described electrical discharger also comprises one end and is connected with electric discharge lamp, the electrical discharger resonance grounding line of the other end ground connection.
Accompanying drawing explanation
Fig. 1 is a kind of vane of wind energy generator of the present invention structural representation in a preferred embodiment;
Fig. 2 is a kind of lightning-arrest assembly of the present invention structural representation in a preferred embodiment;
Fig. 3 is electrical discharger of the present invention structural representation in a preferred embodiment;
Embodiment
A kind of vane of wind energy generator provided by the invention and a kind of lightning protection system and assembly, this assembly and system have chokes function, can be applied to the thunder resisting equipment of all kinds of wind-driven generator, also can be applied on the thunder resisting equipments such as all kinds of lightning conductor.The specific embodiment of a kind of lightning protection system of the present invention and assembly is described referring to accompanying drawing.
Shown in figure 1, this vane of wind energy generator comprises blade body 40, lightning protection system.Described lightning protection system comprises arrester 10, and it is installed on the top of blade body 40, for connecing sudden strain of a muscle thunder and lightning; Lightning-arrest assembly 20, it is connected between arrester 10 and earthed system 30; Earthed system 30, it is connected to the ground.Because arrester 10 is positioned at the top of blade body 40, its effect utilizes its prominent position exceeding protected object that thunder and lightning is guided into self, accepts direct lightning strike electric discharge, blade therefore can be avoided to be struck by lightning.Thunder and lightning is introduced to arrester, and then weaken Lightning Electromagnetic Pulse by lightning-arrest assembly, cut down the steepness of wave edge of lightning current, same blade body self also can consume a part of lightning current.
With reference to figure 2, described blade body 40 forms the inner chamber of a hollow, and this thunder and lightning assembly 20 is arranged at blade body 40 inner chamber kind.Described lightning-arrest assembly 20 comprises: connector 21, and it is connected between arrester 10 and electrical discharger 22; Electrical discharger 22, itself and choke 23 are connected between connector 10 and earthed system 30, for electric discharge; Choke 23, it is in parallel with electrical discharger 22, for controlling electric current when electrical discharger 22 discharges.
Described choke 23 comprises the inductance 231 in parallel with electrical discharger 22, and described choke 23 also comprises one end and is connected with inductance 231, the choke ground wire 232 of another termination earthed system 30.With reference to figure 3, described electrical discharger 22 comprises at least four electric discharge lamps 221, and two lands 222, and these four electric discharge lamps 221 are arranged between two lands 222, are connected and fixed by land 222.Described electrical discharger 22 also comprises one end and is connected with electric discharge lamp 221, the electrical discharger resonance grounding line 223 of another termination earthed system 30.
Arrester 10 connects sudden strain of a muscle, makes lightning current reach the land 222 of choke 23 and electrical discharger 22 by connector 21.Resistance due to inductance 231 is significantly smaller than the resistance of electrical discharger 22, and lightning current major part electric current is released by inductance 231.When lightning current is released by choke 23, at the Same Name of Ends of choke 23 with electrical discharger 22, higher back-pressure guiding discharge device 22 can be produced discharge, the lightning current of about 90% is released by electrical discharger 22, the steepness of wave edge of lightning current can be cut down like this, and because the inductance 231 of choke 23 has larger induction reactance, the generation of Lightning Electromagnetic Pulse greatly can be cut down.
Certainly, described lightning protection system and lightning-arrest assembly can also be applied to other buildings or other lightning arresters, and these those of ordinary skill in the art can realize according to above-described embodiment completely, have just repeated no longer one by one here.
Upper disclosed is only preferred embodiment of the present invention, certainly can not limit the interest field of the present invention with this, therefore according to the equivalent variations that the present patent application the scope of the claims is done, still belong to the scope that the present invention is contained.
