Lightning current ducting capacity.
Inventor has found during the thunder and lightning security protection channel to Wind turbines is studied, the thunder of Wind turbines
There are the weak spots of at least three lightning currents conducting on electric security protection access, i.e., when Wind turbines are by lightening strikes, this
A little weak spots are most vulnerable to damage.Specifically, the lightning current lead when Wind turbines are by lightening strikes, in nonmetallic blade
Thunder amplification current is transmitted to wheel hub.At runtime due to blower, pitch-controlled system controls the angle of blade, i.e. blade and wheel at any time
Can exist between hub and relatively rotate, and be realized by bearing when relatively rotating, but bearing does not allow easy conductive, therefore
It is equipped with lightning current conducting device (for example, lightning protection carbon brush, saw-tooth shaped gaps electric discharge device) between blade and wheel hub, is used for thunder
TV university electric current is transmitted to wheel hub from blade.When unit is attacked by thunder and lightning, thunder amplification current is by lightning current conducting device
It is conducted to wheel hub indirectly from blade, is easy to damage relative to other positions being directly connected to.Therefore, the connection of blade and wheel hub
Place is the first weak spot.In addition, blower is in the running, main shaft and blade can keep identical rotation speed operation, therefore, main shaft and wheel
Also there can be opposite rotation between hub, the junction of main shaft and wheel hub is the second weak spot.With the continuous change of wind direction, partially
Boat system can constantly change the Windward angle of blade, i.e., there are opposite rotations between components and tower for main shaft etc., therefore, this
Place is third weak spot.
When Wind turbines are by lightening strikes, thunder amplification current can be imported from arrester, followed by the first weak spot,
Second weak spot, third weak spot, tower are until ground connection.Therefore, current transformer 3 is arranged anti-safely in Wind turbines thunder and lightning
It protects after the weak spot in channel, i.e., on the lightning current lead 2 of two section tower of Wind turbines top, 5 junction, to monitor
Whether weak spot is struck by lightning, and the reliability of monitoring is improved.
Wherein, as shown in figure 5, the connection component 6 for connecting two adjacent sections tower 5 includes connecting flange 61 and second
Fixing piece 62.End corresponding to two adjacent sections tower 5 is all fixed with connecting flange 61, and two be oppositely arranged connecting flange
61 is fixed by multiple second fixing pieces 62.Specifically, two connecting flanges 61 are fixedly connected using bolt with screw.
Specifically, as shown in figure 4, the Wind turbines include 4 section towers 5, cabin 7 and blade 8.Tower 5 is from top to bottom
51 to the 4th tower of respectively the first tower；Cabin 7 is rotatably arranged in the top of the first tower 51, the first tower 51 it is another
One end is fixed on the top of the second tower 52；Blade 8 is rotatably arranged in cabin 7.Wherein, in lightning monitoring device
Data collector 4 is fixed in cabin 7, which is connect by data line with current transformer 3, for protecting
Hinder the reliable transmission of data.
As shown in figure 5, it is connected with lightning current lead 2 between the first tower 51 and the second tower 52, the lightning current lead 2
Both ends pass through the first fixing piece 9 respectively and be fixed on two connecting flanges 61 being oppositely arranged.For example, the first fixing piece 9 is
Bolt, being arranged on the connecting flange 61 of the first tower 51 is the first bolt, and the connecting flange 61 of the second tower 52 is arranged in
On be the second bolt.Current transformer 3 can be disassembled down any one in the first bolt or the second bolt in specific installation
It is a, current transformer 3 is set in the outside of lightning current lead 2, then the lower bolt of dismantling is returned and is filled, and by current transformer 3
It is fixed in tower.
Optionally, connection component 6 is also possible to include other and the functionally similar component of connecting flange 61, only need to guarantee this
Connection component 6 can be realized being reliably fixed for two adjacent sections tower 5.
The embodiment of the present invention also provides a kind of Wind turbines monitoring system, which is used for the wind-powered electricity generation in wind power plant
Whether unit is monitored by lightening strikes.Specifically include multiple Wind turbines and server, wherein between Wind turbines
It being communicated by annular networking mode, the data collector in each Wind turbines exports processing result into server,
Server is based on processing result and issues alarm signal.
Specifically, the working principle of Wind turbines monitoring system is as follows: when Wind turbines are struck by lightning, connecing on blade
Lightning current can be received by dodging device 1.It is weak by lightning current lead, the first weak spot, the second weak spot and the third inside blade 8
Lightning current is conducted to tower 5 by point.Lightning current is conducted to by the earth by lightning current lead 2 between different towers 5.When tower 5
Between lightning current lead 2 on when thering is lightning current to pass through, be set in and generate induction the current transformer 3 on lightning current lead 2 Nei
Current analog signal, by data line by the data collector 4 in analog signal transmission to cabin 7.Data collector 4 will receive
To analog signal be converted into digital signal, be filtered and enhanced processing after, the server that is sent in Central Control Room.In
It controls indoor server and communication connection is established by Wind turbines looped network and data collector 4, for the place to data collector 4
It manages result and issues alarm signal.
The Wind turbines monitor monitoring of the system using server realization to all Wind turbines, are monitoring Wind turbines
After being struck by lightning, alarm signal is issued in time, and personnel convenient for safeguarding in time overhaul corresponding Wind turbines, to guarantee it
The reliability of lightning protection.
The embodiment of the invention also provides a kind of monitoring methods of Wind turbines, as shown in Figure 6, comprising:
S11 receives the thunder and lightning stream information that Wind turbines are sent.
Wherein, the number of Wind turbines is carried in thunder and lightning stream information.Multiple wind turbines are may include in wind power plant
Group, each Wind turbines both correspond to uniquely number.Lightning monitoring device monitoring in Wind turbines is to lightning current signals
When, the data collector 4 in Wind turbines by the number of the corresponding Wind turbines of lightning current signals affix received together
It is sent to server.When server receives the thunder and lightning stream information of Wind turbines transmission, the volume of its Wind turbines carried is utilized
Number, can confirm to be any platform Wind turbines by lightening strikes.
S12 is based on thunder and lightning stream information, issues alarm signal.
Server issues warning note when receiving the thunder and lightning stream information of Wind turbines transmission, which platform unit is prompted to meet with
By lightning damage, at the same alert maintenance personnel in time to first weak spot in corresponding Wind turbines thunder and lightning security protection channel extremely
Third weak spot carries out inspection confirmation, to ensure the reliability in Wind turbines thunder and lightning security protection channel.When Wind turbines again
When by lightening strikes, thunder and lightning security protection channel can be worked normally, to guarantee the safety of Wind turbines.
Optionally, Wind turbines can also record it by the number of lightening strikes, and the number of record is sent to
Server, so that server is subsequent for statistical analysis.
Optionally, the monitoring method of the Wind turbines be based on the above embodiment in Wind turbines monitoring system carry out
's.
Obviously, the above embodiments are merely examples for clarifying the description, and does not limit the embodiments.It is right
For those of ordinary skill in the art, can also make on the basis of the above description it is other it is various forms of variation or
It changes.There is no necessity and possibility to exhaust all the enbodiments.And it is extended from this it is obvious variation or
