Description
Technical field
This utility model relates to a kind of Wind turbines that is applicable to and reduces the device of Lightning Disaster.
Background technology
When occurring to be struck by lightning, lightning current peak value reaches as high as kilo-ampere up to a hundred, and produces powerful electromagnetic pulse.Thunder and lightning interference
Transient overvoltage includes two parts: one is by the overvoltage in the circuit access arrangement outside connection；Two is at electronic equipment
The internal overvoltage produced due to thunder and lightning electromagnetic coupled effect.
At present the method being taken through discharging rod release thunder energy to prevention nature thunderbolt, its principle be draw thunder with
Self, this principle can be applicable to building, and it is mounted in the peak of building.And the industry operating in natural environment sets
Standby be much can not draw thunder and self, 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.The thunder and lightning harm to these fields, mainly shows as thunder and lightning and produces powerful Transient Electromagnetic
The interference that various electronic equipments are produced by pulse and too high transient voltage and electric current, the most wasting destruction.According to money
Material is introduced, and when magnetic field intensity reaches 0.03 Gauss, may result in computer and produces maloperation, when reaching 2.4 Gauss, will lead
Cause electronic component is breakdown.
In the transient process of thunder discharge, lightning current will produce electromagnetic field, by radiation, sense and the mode such as coupling
The thunder and lightning galvanomagnetic-effects such as interference and surge overvoltage are produced at Wind turbines.Due in Wind turbines electrical equipment and control system
Equipped with various for communicating, regulate 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, and sensitive to electromagnetic interference, they are once
Encroached on by thunder and lightning electromagnetic interference, the most then worked malfunctioning, heavy then permanent damage, causes stoppage in transit accident.We it should be appreciated that
Owing to atmospheric electrical phenomena has obvious randomness, under the conditions of existing guard technology, it is difficult to accomplish to avoid completely electrical equipment
Suffer thunder disaster.
Therefore should take the Lightning Prevention Technique of various ways pointedly, reduce electrical equipment to greatest extent and suffer
The probability of broken by lightning, it is ensured that the safe and reliable operation of electrical equipment.
Utility model content
The technical problems to be solved in the utility model is to provide one and can reduce Wind turbines equipment to greatest extent and meet with
Probability by broken by lightning, it is ensured that the safe and reliable operation of electrical equipment is applicable to Wind turbines and reduces the device of Lightning Disaster.
For solving the problems referred to above, this utility model adopts the following technical scheme that
A kind of Wind turbines that is applicable to reduces the device of Lightning Disaster, and radiation is installed on the two-sided top of blade at Wind turbines

Core inductance, pipe and lightning conductor, the metal of described radial conductive needle shape or the coating of radial conductive needle shape, hollow
Inductance or core inductance, high-voltage diode and lightning conductor series connection, slow down lightning current by air core inductor or core inductance and discharge
Speed, is reduced the faradic current of electrical equipment generation and is simply led to blade direction transmission electric charge by ground by high-voltage diode
Road, on the contrary stop lightning current to be turned on to ground by the metal of radial conductive needle shape, increase the electricity above the blade of Wind turbines
Pressure effect, thundercloud is directed to the two-sided upper installation radial conductive needle of blade by the electric charge of geoinduction before discharging Wind turbines
The metal of shape or the coating of radial conductive needle type shape so that thundercloud reduces and Wind turbines is sensed relative voltage, by examination
Test and reached the condition of disruptive discharge equally and need to improve the voltage levvl of 15%-25%, and then thunder and lightning pair can be considerably reduced
The harm that object discharge produces.The transformation being applicable to the current Wind turbines being currently in use and the wind turbine manufactured
Group.
Further, described lightning conductor is additionally provided with grading ring.
Further, the company of being provided with bottom the metal of radial conductive needle shape or the coating of radial conductive needle shape is stated
Contact, described junction point is connected with earth lead.
The beneficial effects of the utility model are: do not affect the shape of blade during use, the most do not change blade weight, therefore
Do not affect the generating efficiency of Wind turbines, there is presently no the technical method of shape and the weight that can not affect blade；Transformed
The journey construction time is short；Cost of investment is low, has bigger economy；Applied widely, it is easy to popularization and application；With reduce thunder and lightning at present
The device of disaster is completely contradicted, and it is applicable to install exposed at natural environment, does not the most allow thunder and lightning to attack directly and the setting of lightning induction
Standby；The result of this technology application can improve thunder and lightning and object discharge voltage improves the level of 15% to 25%.
