Survey method and basal plane processing method.
Background technology
Wind energy is renewable clear energy sources, is that current techniques are most ripe using wind-power electricity generation, most possesses scale
The electric power resource of exploit condition, wind power generation is that harmony between man and nature development provides the foundation.In order to utilize
More wind energies, the single-machine capacity of wind power generating set is increasing, and the height of blower fan is with the height of tower
With the increase of impeller diameter and constantly raise, the risk of thunderbolt gradually increases, it may be said that thunderbolt has turned into oneself
One of natural calamity maximum to wind power generating set safe operation harm in right boundary；Therefore, a set of reliability
Lightning protection system turned into one of indispensable structure of megawatt wind-power blade.
Wind electricity blade lightning protection system generally comprises four parts：Blade tip arrester, blade arrester, copper
Wire and the lightning-arrest steel band of butt.Two arresters of position of blade are led by being arranged in the copper of blade interior
Line is connected to butt lighting proof strip, then by the brush that is contacted with lighting proof strip by the lightning-arrest system of conduct current main frame
System, and it is eventually led to ground.Only examined during current most of wind-power blade root end lighting proof strip Position Designs
Consider axial dimension requirement, there is no clear stipulaties to radial dimension, be defaulted as blade root internal diameter
Size.But in actual production, blade is because of form, butt size it is difficult to ensure that consistent, Er Qieye
The position of piece butt both sides matched moulds seam causes internal diameter to be herein obviously reduced, Jin Erying because there is hand to paste bound edge
Ring the radius size after lighting proof strip is installed.MW class blade root internal diameter is generally more thanOften
Rule method is difficult to accurately find home position, is also difficult to accurately measure out its radius size.
It is all straight by screw or structure glue that current wind electricity blade industry installs common practice on lighting proof strip
Connect and be fixed on butt inner surface, it is installed radius and fully relies on the size of internal diameter blade to obtain.For example,
Two megawatts of blade root internal diameter theoretical valuesExternal diameter theoretical valueDouble end spiral shell
The diameter theoretical value of circumference where boltAnd actually measure and learn that the size of internal diameter blade rises
Volt is very big, is possibly even reached in matched moulds seam bound edge positionI.e. single side size may be than setting
The meter small about 35mm of size, this error is difficult to receive when blower fan is assembled.
