Fig. 1 is a block diagram of the present invention.
Fig. 2 is another block diagram of the present invention.
[embodiment]
Be described in further detail below in conjunction with accompanying drawing and mode of execution of the present invention:
The lightning-protection system of wind-driven generator is divided into outside lightning-protection system and internal lighting protection system; The internal lighting protection system mainly is the overvoltage protection of electric elements; Adopt power source surge protector and signal Surge Protector; Arrester, down lead, equipotential body connect, earthed system and outside lightning-protection system has, and described outside lightning-protection system carries out lightning protection with blade, gear-box, the driftage mast of wind-driven generator 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 down lead, equipotential connect, earthed system 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 wind-driven generator, 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 Monitor Device on a kind of wind-driven generator; Include monitoring unit 5, the blade, gear-box, the driftage mast that are used for wind-driven generator carry out the detection voltage loader 1 that voltage loads, and are connected first magnetoelectric transducer 2 on the root of blade down lead; Be connected second magnetoelectric transducer 3 at gear-box 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 monitoring unit 5 respectively.
Said detection voltage loader 1 is the DC low-voltage power supply; The example that detects on-load voltage device 1 that only draws among Fig. 1, the present invention also can as shown in Figure 2ly separately set up 3 to detect on-load voltage devices 1, loads thereby carry out separate voltages; Do not disturb mutually, the present invention adopts the 24V potentiostat.
Working principle of the present invention is such: because the 3rd magnetoelectric transducer 4 at second magnetoelectric transducer 3 at first magnetoelectric transducer 2 of root of blade, gear-box 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 down lead 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 checkout value through voltage can each parts of early warning is when monitoring unit 5 shows the real voltage value of each parts; In the time of in true checkout value is in the permission wave 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 present invention adopts is 24V, and it allows wave range to be set to 24V ± 5%; When actual float value is when surpassing this permission wave range; Monitoring unit 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 part immediately.
