Description
Technical field：
It the utility model is related to anti-thunder technical field, and in particular to a kind of wind-driven generator drives thunder protector.
Background technology：
Wind energy is renewable clear energy sources, is that current techniques are most ripe using wind-power electricity generation, most possesses scale development condition
Electric power resource.It is increasing with the single-machine capacity of wind power generating set, in order to absorb more wind energies, the height of blower fan with
Hub height and impeller diameter increase continuous rise, and the risk of thunderbolt is continuously increased, and thunderbolt turns into nature to be sent out wind-force
The maximum natural calamity of group of motors safe operation harm.When being struck by lightning, conducting lightning currents are passed by all wind-driven generator components
Ground is directed at, because wind-driven generator is located at strong wind area, on hills or ridge, its height is far above the ground of surrounding for usual addressing
Shape atural object, it is relatively poor to the conductive performance of lightning current along with wind-driven generator infield soil resistivity is generally higher,
It is particularly susceptible to the attack of direct lightning strike, sideflash and induced lightening.
The lightning protection of modern wind generator is typically different than the lightning protection of common building thing, and it needs emphasis to solve blade and wheel
The lightning protection problem such as hub, gear-box, bearing, transmission device, generator, electric part, control system.The thunderstruck portion of blower fan
The maintenance cost (including labour cost, part take and lifting cost etc.) of part is very high, wherein the maintenance cost most expensive of blade damage.Wind
After power generator suffers broken by lightning, analysis and follow-up maintenance due to failure infringement, plus ordering period and transport phase, it can cause
The downtime of a period of time.Generated energy not only is lost by this downtime, and reduces the receipts of the wind field owner economically
Enter.According to the statistics of foreign countries, lightning fault is all bigger than shutting down influence caused by average other failures.Damage to crops caused by thunder is to threaten wind-driven generator
Group safety in production and the Tough questions of wind field benefit.Wind-power electricity generation is emerging industry, so far in terms of lightning protection achievement in research, wind-force
The outside direct lightning strike protection of generating set, emphasis is placed upon improving on the lightning-protection system of blade；
The general outside thunderbolt route of blower fan is：Be struck by lightning arrester → (blade inner chamber) guide wire → blade root (on blade)
Portion → cabin mainframe → ad hoc (pylon) downlead → grounded screen introduces the earth.But it is struck by lightning from Denmark and Germany's statistics
In damaged location, the blade damage that thunder and lightning is attacked directly accounts for 15%~20%, and 80% above is the other equipment being connected with downlead,
Introduced by thunder and lightning during the earth and produce overvoltage and damage.
The wind power generating set of China occupies significant proportion in high altitude localities, and high altitude localities thunder and lightning is from intensity and frequency
All aggravate on degree, sudden strain of a muscle efficiency is connect to blower fan lightning-protection system and proposes higher requirement.And wind-powered electricity generation complete machine goes out quality guarantee at present
Ratio is continuously increased, and unit, blade also constantly expand because of the ratio that thunder loses.Have within 2014 more than 200 blade damages, wherein because
Thunder loss ratio is up to 80%.Cause current blade because thunder loss ratio increase the main reason for be that blade lightning Protection Design does not have substantially
Carry out thunderbolt design verification, blade lightning-protection system effectively connects that sudden strain of a muscle rate is low, caused by arrester design redundancy deficiency.
