Description
Technical field
The present invention relates to a kind of methods reducing Lightning Disaster suitable for Wind turbines.
Background technology
Lightning current peak value reaches as high as kilo-amperes up to a hundred when being struck by lightning, and generates powerful electromagnetic pulse.Thunder and lightning interference
Transient overvoltage includes two parts:First, entering the overvoltage in equipment by the circuit outside connection；Second is that in electronic equipment
The overvoltage that inside is generated due to the effect of thunder and lightning electromagnetic coupling.
At present to prevent nature lightning stroke be taken through lightning rod discharge thunder energy method, principle be draw thunder with
Itself, this principle can be applied to building, it is mounted in the peak of building.And the industry for operating in natural environment is set
Standby is much that cannot draw thunder and itself, such as Wind turbines, transmission line of electricity and the computer skill being closely related with new and high technology
The fields such as art, space flight and aviation, communication.Harm of the thunder and lightning to these fields is mainly shown as that thunder and lightning generates powerful Transient Electromagnetic
The destruction for the interference or even destructive that pulse and excessively high transient voltage and electric current generate various electronic equipments.According to money
Material is introduced, and when magnetic field intensity reaches 0.03 Gauss, be may result in computer and is generated maloperation, when reaching 2.4 Gauss, will lead
It is breakdown to send a telegraph subcomponent.
In the transient process of thunder discharge, lightning current will generate electromagnetic field, pass through the modes such as radiation, induction and coupling
The thunders and lightnings galvanomagnetic-effects such as interference and surge overvoltage are generated in Wind turbines.Due in Wind turbines electrical equipment and control system
Equipped with various for communicating, adjusting and the electronic equipment of data processing intent, for electrical equipment, these equipment are general
All over there is a common weakness, i.e. dielectric strength is low, and overvoltage tolerance is poor, sensitive to electromagnetic interference, they are once
It is encroached on by thunder and lightning electromagnetic interference, gently then work failure, and heavy then permanent damage causes stoppage in transit accident.We it should be appreciated that
Since atmospheric electrical phenomena has apparent randomness, under the conditions of existing guard technology, it is difficult to accomplish to avoid electrical equipment completely
By thunder disaster.
Therefore should pointedly take the Lightning Prevention Techniques of various ways, reduce to the maximum extent electrical equipment by
The probability of broken by lightning, it is ensured that the safe and reliable operation of electrical equipment.
Invention content
The technical problem to be solved in the present invention is to provide one kind capable of reducing Wind turbines equipment to the maximum extent by thunder
Hit the probability of damage, it is ensured that the safe and reliable operation of electrical equipment is suitable for the method that Wind turbines reduce Lightning Disaster.
To solve the above problems, the present invention adopts the following technical scheme that：
A method of being suitable for Wind turbines and reduce Lightning Disaster, in the two-sided top installation radiation of the blade of Wind turbines
The metal of shape conductive pin shape or the coating of radial conductive needle shape, and with air core inductor or core inductance, high-voltage diode
Lightning conductor series connection in the blade of Wind turbines, slows down the lightning current velocity of discharge by air core inductor or core inductance, subtracts
The induced current and charge pathway is only transmitted from ground to blade direction by high-voltage diode that few electrical equipment generates, it is on the contrary
It prevents lightning current from being connected to ground by the metal of radial conductive needle shape, increases the voltage effect above the blade of Wind turbines,
Thundercloud by the charge of geoinduction before Wind turbines electric discharge to being directed to the two-sided upper gold for installing radial conductive needle shape of blade
The coating of category or radial conductive needle type shape so that thundercloud is reduced incudes opposite voltage to Wind turbines, is obtained by experiment
The condition for equally reaching disruptive discharge needs to improve the voltage level of 15%-25%, and then can considerably reduce thunder and lightning and be put to object
The harm that electricity generates.Suitable for the transformation of Wind turbines currently in use and the Wind turbines manufactured at present.
Further, it is additionally provided with grading ring on the lightning conductor.
Further, the coating bottom of the metal or radial conductive needle shape of stating radial conductive needle shape is provided with company
Contact, the tie point are connected with ground wire.
Beneficial effects of the present invention are：The shape of blade is not influenced when use, without changing blade weight, therefore not shadow yet
The generating efficiency of Wind turbines is rung, there is presently no the technical methods of the shape and weight that can not influence blade；Transformation process is applied
Short time limit；Cost of investment is low, the economy with bigger；It is applied widely, application easy to spread；Lightning Disaster is reduced with current
Method completely contradict, it be suitable for install it is exposed in natural environment, and do not allow thunder and lightning attack directly and lightning induction equipment；It should
The level that thunder and lightning improves object discharge voltage 15% to 25% can be improved in the result of technology application.
