Description
[technical field]
The present invention relates to anti-thunder technical field, the lightning protection on-Line Monitor Device particularly on a kind of wind-driven generator.
[background technique]
In view of sea climate environment has huge difference with land, thunder activities is more frequent, lightning strike accident district occurred frequently, in order to improve aerogenerator unit safe, reducing the possibility of lightning strike accident, avoiding unnecessary loss, improve group of motors anti-lightning ability, the present inventor have developed a set of lightning protection monitoring system, the runnability of Real-Time Monitoring lightning-protection system based on the outside lightning-protection system of wind-driven generator, and carries out early warning to the fault that lightning-protection system occurs.
[summary of the invention]
Instant invention overcomes the deficiency of above-mentioned technology, providing one can carry out on-line checkingi and early warning to wind-driven generator lightning-protection system, and structure is simple, install and lightning protection on-Line Monitor Device easy to maintenance.
For achieving the above object, present invention employs following technical proposal:
Lightning protection on-Line Monitor Device on a kind of wind-driven generator, include monitoring unit 5, the detection voltage-drop loading device 1 of voltage-drop loading is carried out for the blade to wind-driven generator, gear-box, driftage mast, be connected to the first magnetoelectric transducer 2 of root of blade, be connected to second magnetoelectric transducer 3 at gear-box afterbody carbon brush place, and be connected to the 3rd magnetoelectric transducer 4 at driftage afterbody carbon brush place; Described first magnetoelectric transducer 2 signal output part, the second magnetoelectric transducer 3 signal output part, the 3rd magnetoelectric transducer 4 signal output part are connected with monitoring unit 5 respectively.

The invention has the beneficial effects as follows: 1, monitor staff just clearly can understand lightning protection device working condition by Surveillance center; find timely and effectively, fix a breakdown; ensure that lightning protection device runs in the secure state; reduce the electrical failure because thunder and lightning causes, thus reduce power loss and dead time.2, reduce the labor intensity of attendant, improve working efficiency.3, have that structure is simple, price is low, safe and reliable, the advantage such as easy to maintenance.
[accompanying drawing explanation]
Fig. 1 is 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 embodiments 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 overvoltage protection of internal lighting protection system mainly electric elements, adopt power source surge protector and signal Surge Protector, and outside lightning-protection system has arrester, down lead, equipotential body connects, earthed system, described outside lightning-protection system and the blade of wind-driven generator, gear-box, driftage mast carries out lightning protection connection, the blade tip of blade, lightning protection metal frame on the upside of gear case body, measure on mast and all arrester is installed, and pass through down lead, equipotential link, earthed system forms outside lightning-protection system operator guards, it is for guiding to large ground when thunder and lightning hits thunder and lightning, the safety of each parts of protection wind-driven generator, and lightning protection on-line monitoring system monitoring lightning-protection system runs 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 detection voltage-drop loading device 1 of voltage-drop loading is carried out for the blade to wind-driven generator, gear-box, driftage mast, be connected to the first magnetoelectric transducer 2 on root of blade down lead, be connected to second magnetoelectric transducer 3 at gear-box afterbody carbon brush place, and be connected to the 3rd magnetoelectric transducer 4 at driftage afterbody carbon brush place; Described first magnetoelectric transducer 2 signal output part, the second magnetoelectric transducer 3 signal output part, the 3rd magnetoelectric transducer 4 signal output part are connected with monitoring unit 5 respectively.
Described detection voltage-drop loading device 1 is DC low-voltage power supply, only draw the example that is detected voltage-drop loading device 1 in Fig. 1, the present invention also can separately set up 3 to detect voltage-drop loading device 1 as shown in Figure 2, thus carries out independent voltage-drop loading, do not interfere with each other, the present invention adopts 24V potentiostat.
Working principle of the present invention is such: due to the first magnetoelectric transducer 2 of root of blade, second magnetoelectric transducer 3 at gear-box afterbody carbon brush place, 3rd magnetoelectric transducer 4 at driftage afterbody carbon brush place respectively with between detection voltage-drop loading device 1, all there is certain conductor and be connected distance, described conductor is down lead or the generator component of lightning-protection system, and system failure fault of being struck by lightning usually occurs in above position, certain fluctuation is had when detecting actual voltage value on it by sensor, logical superpotential checkout value can the performance quality of each parts of early warning, when monitoring unit 5 shows the real voltage value of each parts, when true checkout value be in be worth in set allowable fluctuation range according to detection voltage-drop loading device 1 time, be judged as that lightning-protection system function is normal, the on-load voltage of the detection voltage-drop loading device 1 that the present invention adopts is 24V, its allowable fluctuation range is set to 24V ± 5%, when actual float value is above this allowable fluctuation range, monitoring unit 5 judges current lightning-protection system component failure, report to the police, staff should carry out the maintenance of corresponding part immediately.
