Description

Technical Field

[0001] This application relates to the field of electrical engineering, and in particular to a continuity detection system for a wind turbine lightning protection system based on a Hall effect detection module. Background Technology

[0002] In wind turbines, lightning rods are installed at the blade tips to receive lightning strikes. Down conductors are located inside the blades and tower, serving as crucial channels for dissipating lightning current. If a down conductor breaks, the current cannot be effectively conducted to the lightning protection system during a lightning strike, causing the wind turbine's lightning protection system to fail and significantly increasing the risk of damage to the turbine from lightning strikes. Therefore, routine maintenance must regularly check the continuity of the down conductors between the blades and the lightning protection system. If a down conductor breaks, the lightning current cannot be properly discharged, potentially damaging the wind turbine and its internal equipment due to lightning overvoltage, or even causing serious malfunctions.

[0003] In related technologies, manual inspection is typically used to check the continuity of the down conductors inside the wind turbine blades and tower. However, due to limited manpower and the large workload, manual inspection of the down conductors inside the wind turbine cannot promptly detect faults in the wind turbine's lightning protection system. Therefore, how to promptly detect faults in the down conductors inside the wind turbine has become an urgent problem to be solved. Utility Model Content

[0013] The continuity detection system for a wind turbine lightning protection system based on Hall elements provided in this application embodiment has at least the following technical effects.

[0014] The drone's electrical signal generation component outputs an electrical signal at the lightning arrester on the wind turbine blade to simulate a lightning strike. This signal is transmitted to the signal receiving module via the wind turbine's internal downlead. Upon receiving the signal, the receiving module induces current in the lightning protection grounding module. Based on the principle of electromagnetic induction, the current through the first resistor generates an induced magnetic field. This induced magnetic field causes the Hall effect detection module to obtain a Hall voltage. The Hall effect detection module internally converts and detects this voltage to determine if the downlead inside the wind turbine is faulty. If the Hall effect detection module detects a voltage, it indicates that the downlead inside the wind turbine is conductive, allowing for rapid detection of the downlead within the wind turbine.

[0023] In a first aspect, embodiments of this application provide a continuity detection system for a wind turbine lightning protection system based on a Hall effect detection module. Figure 1 This is a schematic diagram of a continuity detection system for a wind turbine lightning protection system based on a Hall effect detection module, according to an exemplary embodiment. Figure 2 This is a schematic diagram illustrating the internal circuitry of a lightning protection grounding module and a Hall effect detection module according to an exemplary embodiment, as shown below. Figure 1 and Figure 2 As shown, the wind turbine includes blades, and the blades are equipped with lightning arresters 100. The continuity detection system of the wind turbine lightning protection system based on the Hall effect detection module includes: a drone 200, a lightning protection grounding module 300, and a Hall effect detection module 400.

[0024] The UAV 200 is equipped with an electrical signal generating component 201, which is used to electrically connect to the lightning arrester 100 to output an electrical signal 202; The lightning protection grounding module 300 includes a first resistor 302 and an electrical signal receiving component 301. The first resistor 302 includes a first end and a second end. The first end is electrically connected to the electrical signal receiving component 301, and the second end is grounded. The electrical signal receiving component 301 is used to receive electrical signal 202. The Hall detection module 400 is located in the induced magnetic field generated when the first resistor 302 is turned on.

[0025] The wind turbine has several blades, and each blade has a lightning arrester 100 at its tip. A drone 200 flies to the blade at the top of the wind turbine and sends an electrical signal to the lightning arrester 100 via an electrical signal generating component 201 on the drone 200. The electrical signal 202 sent by the electrical signal generating component 201 simulates the instantaneous voltage generated when lightning strikes the wind turbine.

[0026] A wind turbine consists of a tower and blades. Inside the wind turbine is a down conductor 600, used to discharge the instantaneous voltage generated when lightning strikes the turbine to the ground. Specifically, the down conductor 600 includes a first down conductor 601 from the blade tip to the blade root, a second down conductor 602 from the blade root to the top of the tower, and a third down conductor 603 from the top of the tower to the bottom of the tower. The wind turbine uses the down conductor 600 to transmit excessively high voltage generated by lightning to the lightning protection grounding module 300, thus guiding the excessive voltage to the ground and preventing damage to the wind turbine from excessive voltage. Therefore, the drone 200 flies to the tip of the blade and sends an electrical signal 202 to the lightning arrester 100 to simulate a lightning strike on the lightning arrester 100. The electrical signal 202 passes sequentially through the first down conductor 601, the second down conductor 602, and the third down conductor 603 inside the wind turbine to reach the electrical signal receiving component 301 in the lightning protection grounding module 300. When the electrical signal receiving component 301 receives the electrical signal, the lightning protection grounding module 300 begins to conduct electricity, and the current flows to the first resistor 302. When the current passes through the first resistor 302, an induced magnetic field is generated, causing the Hall detection module 400 to be placed in the magnetic field. The Hall detection module 400, placed in the magnetic field, generates a Hall voltage based on the Hall principle. The Hall detection module 400 internally converts and detects the Hall voltage to obtain the detection result. If the electrical signal 202 can reach the electrical signal receiving component 301 through the down conductor 600 inside the wind turbine, it causes the lightning protection grounding module to generate current and obtain an induced magnetic field. Under the induced magnetic field, the Hall detection module 400 obtains the Hall voltage, processes and detects the Hall voltage, and determines that there is no fault in the down conductor 600 inside the wind turbine.

[0027] By controlling the drone 200 to fly to the lightning arrester 100 at the tip of the blade and sending an electrical signal 202, and then observing the Hall effect detection module 400, it is possible to directly determine whether there is a fault in the down conductor 600 of the wind turbine. Therefore, the detection system using the drone 200, the lightning protection grounding module 300, and the Hall effect detection module 400 can quickly and accurately detect the down conductor 600 in the wind turbine.

[0028] Optionally, such as Figure 1As shown, the lightning protection grounding module 300 is the internal circuit of the wind turbine and is located at the bottom inner side of the wind turbine. Optionally, the Hall detection module 400 can be located outside the wind turbine, that is, outside the bottom of the wind turbine tower; the Hall detection module 400 can also be located inside the wind turbine, on one side of the lightning protection grounding module 300.

[0029] In one embodiment, Figure 3 This is a schematic diagram of the internal circuitry of a lightning protection grounding module and a Hall effect detection module according to an exemplary embodiment, as shown below. Figure 3 As shown, the Hall effect detection module 400 includes a Hall effect measurement component 401 and an ammeter 402. The Hall effect measurement component 401 is connected in series with the ammeter 402, and one end of the ammeter 402 is electrically connected to the Hall effect measurement component 401, while the other end is grounded.

[0030] The lightning protection grounding module 300 also includes a third resistor 303, one end of which is electrically connected to the electrical signal receiving component 301, and the other end is electrically connected to the second end of the first resistor 302. The third resistor 303 is used to divide the voltage or current in the lightning protection grounding module 300 to protect the lightning protection grounding module 300.

[0031] When the electrical signal receiving component 301 receives the electrical signal 202, it causes the lightning protection grounding module 300 to conduct electricity and generate current. This current generates an induced magnetic field, placing the Hall effect detection module 400 within the magnetic field. The Hall effect measurement component 401 generates a Hall voltage based on the Hall effect principle and processes the Hall voltage to obtain the current. The current flows through the ammeter 402, causing its pointer to rotate. The rotation of the ammeter 402's pointer confirms that the down conductor 600 inside the wind turbine is in a conductive state. In other words, the electrical signal 202 sent by the UAV 200 can be transmitted sequentially through the first down conductor 601, the second down conductor 602, and the third down conductor 603 to the electrical signal receiving component 301, causing the lightning protection grounding module 300 to generate current. This current generates an induced magnetic field, causing the Hall effect measurement component 401, located next to the first resistor 302, to generate a Hall voltage, which is then processed to obtain the current, causing the ammeter 402 to rotate. When the pointer in ammeter 402 rotates or the value of ammeter 402 changes, it can be directly determined that there is no fault in the first down conductor 601, the second down conductor 602 and the third down conductor 603 inside the wind turbine. Therefore, it is possible to quickly detect whether there is a fault in the down conductor 600 inside the wind turbine by observing ammeter 402.

[0032] In the Hall effect measurement component 401, the Hall voltage is obtained through the Hall principle, and the Hall voltage is processed to obtain the current. The specific implementation method is as follows: Figure 4This is a schematic diagram of the internal circuitry of a lightning protection grounding module and a Hall effect detection module according to another exemplary embodiment, such as... Figure 4 As shown, the Hall measurement assembly 401 includes a Hall element 411, an amplifier circuit 412, and a conversion circuit 413. The Hall element 411 is electrically connected to the amplifier circuit 412, and the amplifier circuit 412 is electrically connected to the conversion circuit 413.

[0033] In the Hall effect measurement assembly 401, when the Hall element 411 is in a magnetic field, a Hall voltage is obtained based on the Hall principle. Since the Hall voltage generated by the Hall element 411 is very small and difficult to observe, it is amplified by the amplifier circuit 412 to make it observable. Voltage is easily affected by external factors, leading to low detection accuracy. Therefore, the Hall voltage amplified by the amplifier circuit 412 is input to the conversion circuit 413, which converts the voltage into current. Current is not only highly resistant to interference but also easy to measure. Therefore, the conversion circuit 413 is electrically connected to the ammeter 402, so that the current output by the conversion circuit 413 passes through the ammeter 402. The rotation of the ammeter 402 directly reflects whether the down conductor 600 inside the wind turbine is conductive. If any segment of the first down conductor 601, the second down conductor 602, or the third down conductor 603 inside the wind turbine is blocked, the electrical signal 202 cannot be transmitted to the electrical signal receiving component 301 through the down conductor 600. Therefore, the lightning protection grounding module 300 cannot conduct electricity, there is no current, and no induced magnetic field can be generated to cause the Hall element 411 to generate a Hall voltage. Without a Hall voltage, the amplifier circuit 412 and the conversion circuit 413 cannot work, and consequently, no current flows through the ammeter 402. The ammeter 402 cannot rotate or update the current value. Therefore, the continuity of the down conductor 600 inside the wind turbine can be quickly observed through the ammeter 402.

[0034] Figure 5 This is a schematic diagram of the internal circuitry of a Hall effect measurement component according to an exemplary embodiment, such as... Figure 5 As shown, the Hall measurement assembly 401 includes: a Hall element 411, an amplifier circuit 412, and a conversion circuit 413.

[0035] Amplifier circuit 412 includes a first input terminal 20, a second input terminal 21 and a voltage output terminal 22. The first input terminal 20 is electrically connected to Hall element 411, the second input terminal 21 is grounded, and the voltage output terminal 22 is electrically connected to conversion circuit 413. The Hall element 411 includes a signal output terminal 11 and a ground terminal 10. The signal output terminal 11 is electrically connected to the first input terminal 20, and the ground terminal 10 is electrically connected to the second input terminal 21. When the current in the lightning protection grounding module 300 generates an induced magnetic field, the Hall element 411 is connected to the power supply U0, causing a drive current to be generated inside the Hall element 411. Based on the Hall principle, the Hall element 411, under the induced magnetic field, generates a Hall voltage between the signal output terminal 11 and the ground terminal 10. This generated Hall voltage is input to the first input terminal 20 of the amplifier circuit 412. The Hall voltage is amplified by the operational amplifier and feedback resistor network in the amplifier circuit 412 to obtain an amplified output voltage. The output voltage is easier to observe than the Hall voltage.

[0036] Figure 6 This is a schematic diagram of the internal circuitry of a Hall effect measurement component according to another exemplary embodiment, such as... Figure 6 As shown, the conversion circuit 413 includes a third input terminal 30, a fourth input terminal 31, and a current output terminal 32. The third input terminal 30 is electrically connected to the voltage output terminal 22, the fourth input terminal 31 is grounded, and the current output terminal 32 is electrically connected to the ammeter 402.

[0037] Voltage is easily affected by external factors, and measuring voltage also requires a separate branch circuit. Therefore, the output voltage of amplifier circuit 412 is converted into current by conversion circuit 413. Current has strong anti-interference properties and can be observed by connecting ammeter 402 in series with the original circuit. Therefore, conversion circuit 413 converts the output voltage of amplifier circuit 412 into detection current for easier detection.

[0038] It should be noted that, Figure 5 and Figure 6 It is one form of amplifier circuit 412 and conversion circuit 413. The specific circuit form is not limited and is determined according to the application scenario and actual needs.

[0039] In one embodiment, Figure 7 This is a schematic diagram illustrating a continuity detection system for a wind turbine lightning protection system based on a Hall effect detection module, according to another exemplary embodiment. Figure 7 As shown, the continuity detection system of the wind turbine lightning protection system also includes a camera component 500. The Hall effect detection module 400 is located within the field of view of the camera component 500. The position of the camera component 500 allows it to clearly capture the ammeter 402 in the Hall effect detection module 400. The position of the camera component 500 is not specifically limited.

[0040] The camera assembly 500 includes a communication component that communicates with a server to transmit captured images. The camera assembly 500 captures images of the pointer rotation of the ammeter 402 and transmits these images to the system's server via the communication component. The server processes the acquired images to enable real-time fault monitoring, obtain information on faults in the downlead 600 inside the wind turbine, and promptly repair the downlead 600.

[0041] In one embodiment, the lightning protection grounding module 300 is located at the inner bottom of the wind turbine, and the Hall effect detection module 400 is located on the outer side of the wind turbine. The Hall effect detection module 400 is situated within the induced magnetic field generated when the first resistor 302 in the lightning protection grounding module 300 is turned on. Specifically, the Hall effect detection module 400 is located within a preset range starting from the outer edge of the bottom of the wind turbine tower, ensuring that the Hall effect detection module 400 is within the induced magnetic field. This application connects the Hall effect detection module 400 without altering the original circuitry of the wind turbine. The detection system does not require additional detection circuitry, simplifying the overall circuit design of the detection system, thereby reducing economic costs and improving system reliability.

[0042] In summary, the continuity detection system for a wind turbine lightning protection system based on a Hall effect detection module provided in this application simulates a lightning strike by controlling a drone 200 to fly to the tip of the wind turbine blades and transmit an electrical signal 202. The system determines whether the electrical signal 202 is transmitted to the lightning protection grounding module 300, causing the module to conduct and generate current. This current generates an induced magnetic field, causing the Hall element 411 to produce a Hall voltage. This Hall voltage is amplified by an amplifier circuit 412, and a conversion circuit 413 converts the output voltage of the amplifier circuit 412 into current. The rotation of an ammeter 402 determines whether the first down conductor 601, the second down conductor 602, and the third down conductor 603 inside the wind turbine are conducting. If the ammeter 402 does not rotate, it indicates that any one or more of the first down conductor 601, the second down conductor 602, and the third down conductor 603 inside the wind turbine are blocked, indicating a fault in the down conductor 600, requiring repair of the wind turbine. By controlling the drone 200 and observing the ammeter 402, the down conductor 600 inside the wind turbine can be quickly detected. Furthermore, by incorporating a camera component 500, images of the ammeter 402 are captured and transmitted to a server for detection, making data collection faster. The presence of a fault is confirmed by whether the ammeter 402 rotates in the image, improving fault detection efficiency. The Hall effect detection module 400 of this application is electrically connected to the existing circuitry inside the wind turbine, eliminating the need for additional detection circuitry. This simplifies the circuit design of the detection system. The use of fewer modules and components reduces the failure rate of these components, thereby ensuring the reliability of the detection system and lowering economic costs.

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0044] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application.
