[background technology]
In view of the sea climate environment has huge difference with the land, the thunderstorm activity is more frequent, the lightning strike accident district occurred frequently; In order to improve wind-powered electricity generation unit safety property, reduce the possibility of lightning strike accident, avoid unnecessary loss; Improve the anti-thunderbolt ability of group of motors; The inventor has developed a cover lightning protection monitoring system based on the outside lightning-protection system of aerogenerator, monitors the ruuning situation of lightning-protection system in real time, and the fault that lightning-protection system takes place is carried out early warning.
[utility model content]
The utility model has overcome the deficiency of above-mentioned technology, and providing a kind of can carry out online detection and early warning to the aerogenerator lightning-protection system, simple in structure, installation and lightning protection on-line monitoring system easy to maintenance.
For realizing above-mentioned purpose, the utility model has adopted following technical proposal:
Lightning protection on-line monitoring system on a kind of aerogenerator; Include watch-dog 5; The blade, gear case, the driftage mast that are used for aerogenerator carry out the detection voltage loader 1 that voltage loads; Be connected first magnetoelectric transducer 2 of root of blade, be connected second magnetoelectric transducer 3 at gear case afterbody carbon brush place, and the 3rd magnetoelectric transducer 4 that is connected driftage afterbody carbon brush place; Said first magnetoelectric transducer, 2 signal output parts, second magnetoelectric transducer, 3 signal output parts, the 3rd magnetoelectric transducer 4 signal output parts are connected with watch-dog 5 respectively.
Said detection voltage loader 1 is the potentiostat of 24V.
Said detection voltage loader 1 is 3.
The beneficial effect of the utility model is: 1, the monitoring staff can just can clearly understand the working condition of lightning protection device through Surveillance center; Find timely and effectively, fix a breakdown; Guaranteed that lightning protection device moves under safe condition; Reduce the electric fault that causes because of thunder and lightning, thereby reduce power loss and stop time.2, reduce maintainer's labour intensity, improved work efficiency.3, have advantages such as simple in structure, that price is low, and is safe and reliable, easy to maintenance.

Fig. 1 is the block diagram of the utility model.
Fig. 2 is another block diagram of the utility model.
[embodiment]
Embodiment below in conjunction with accompanying drawing and the utility model is described in further detail:
The lightning-protection system of aerogenerator is divided into outside lightning-protection system and internal lighting protection system; The internal lighting protection system mainly is the overvoltage protection of electrical equipment; Adopt power source surge protector and signal Surge Protector; Arrester, downlead, equipotential body connect, earthing device and outside lightning-protection system has, and described outside lightning-protection system carries out lightning protection with blade, gear case, the driftage mast of aerogenerator and is connected, and on the lightning protection metal frame of the blade tip of blade, gear case body upside, the measurement mast arrester are installed all; And through downlead, equipotential connect, earthing device forms outside lightning-protection system protection structure; It is used for when thunder and lightning hits, guiding to big ground to thunder and lightning, the safety of each parts of protection aerogenerator, and lightning protection on-line monitoring system monitoring lightning-protection system moves fine or not situation in each parts.
As shown in Figure 1; Lightning protection on-line monitoring system on a kind of aerogenerator; Include watch-dog 5, the blade, gear case, the driftage mast that are used for aerogenerator carry out the detection voltage loader 1 that voltage loads, and are connected first magnetoelectric transducer 2 on the root of blade downlead; Be connected second magnetoelectric transducer 3 at gear case afterbody carbon brush place, and the 3rd magnetoelectric transducer 4 that is connected driftage afterbody carbon brush place; Said first magnetoelectric transducer, 2 signal output parts, second magnetoelectric transducer, 3 signal output parts, the 3rd magnetoelectric transducer 4 signal output parts are connected with watch-dog 5 respectively.
Said detection voltage loader 1 is the DC low-voltage power supply; An example that detects on-load voltage device 1 only draws among Fig. 1; The utility model also can as shown in Figure 2ly separately set up 3 to detect voltage loader 1; Load thereby carry out separate voltages, do not disturb mutually, the utility model adopts the 24V potentiostat.
The principle of work of the utility model is such: because the 3rd magnetoelectric transducer 4 at second magnetoelectric transducer 3 at first magnetoelectric transducer 2 of root of blade, gear case afterbody carbon brush place, driftage afterbody carbon brush place all has certain conductor between the voltage loader 1 and is connected distance with detecting respectively; Said conductor is the downlead or the generator component of lightning-protection system; And thunderbolt system failure fault usually occurs in above position; Have certain fluctuation on it during actual voltage value through sensor, the performance quality that the detected value through voltage can each parts of early warning is when watch-dog 5 shows the real voltage value of each parts; In the time of in true detected value is in the permission fluctuation range that sets according to detection voltage loader 1 value; It is normal to be judged as the lightning-protection system function, and the on-load voltage of the detection voltage loader 1 that the utility model adopts is 24V, and it allows fluctuation range to be set to 24V ± 5%; When actual float value is when surpassing this permission fluctuation range; Watch-dog 5 judges that current lightning-protection system parts break down, and reports to the police, and the staff should carry out the maintenance of corresponding component immediately.
