[0002] The Changdao high-speed maglev train utilizes the electromagnetic attraction between conventional DC electromagnets and highly conductive magnetic materials, achieving train levitation and guidance through automatic closed-loop control. The system features a small air gap, typically around 10 mm, and can reach speeds of 400-500 km / h, making it ideal for long-distance, rapid intercity transportation. The levitation electromagnet is a core component of the Changdao high-speed maglev system. It interacts with the ferromagnetic material on the track, generating electromagnetic attraction and levitating the train above the track.

If the magnetic poles in a suspension electromagnet are damaged, such as by a short circuit between turns or damage to the insulation layer between turns of the coil, some of the coil turns will become conductive, potentially causing leakage at the magnetic poles and potentially leading to safety accidents.

[0053] The following describes the embodiments of the present application in conjunction with the accompanying drawings. The terms used in the implementation methods of the present application are only used to explain the specific embodiments of the present application and are not intended to limit the present application.

[0054] The embodiments of the present application are described below in conjunction with the accompanying drawings. Those skilled in the art will appreciate that, with the development of technology and the emergence of new scenarios, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.

[0055] The terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequential order. It should be understood that the terms used in this way can be interchangeable under appropriate circumstances, and this is merely a way of distinguishing the objects of the same attributes when describing them in the embodiments of the present application. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, so that the process, method, system, product or equipment comprising a series of units need not be limited to those units, but may include other units that are not clearly listed or inherent to these processes, methods, products or equipment.

[0056] This application can be applied to scenarios during vehicle maintenance or testing.

[0057] Suspension electromagnets are affected by copper and iron losses, causing the pole temperature to rise. Excessively high pole temperatures can damage the insulation between coil turns, leading to abnormally low field strength and compromising the safe operation of the maglev vehicle. Furthermore, prolonged high pole temperatures can cause the resin encapsulation layer on the pole surface to bulge and deform, making heat dissipation difficult. Damage to the insulation layer can lead to current leakage, posing a safety risk.

[0058] In related technologies, measuring the internal resistance of the magnetic poles in a suspended electromagnet is used to determine whether a short circuit has occurred between turns. This is because the internal resistance of the suspended electromagnet's magnetic poles is determined by the resistance of its coil. Under normal circumstances, the insulation between turns of the coil is intact, and the internal resistance is primarily determined by the resistance of the wire, resulting in a relatively stable internal resistance. When a short circuit occurs between turns of the magnetic poles, the insulation between turns of the coil is damaged, causing some of the turns to conduct. In this case, the effective conductive path of the coil changes, significantly reducing the internal resistance.

[0059] During the research process, the applicant found that the accuracy of the relevant technology is not high for the following reasons: When the damaged area of ​​the insulation layer between the turns of the magnetic pole coil is small, the insulation performance of only a few coil turns may be reduced. At this time, the magnetic field strength is reduced, and a larger current is needed to increase the magnetic field strength. Increasing the current aggravates the damage to the magnetic pole and poses a risk of safety accidents. If the insulation performance of only a few coil turns is reduced, the overall conductive path of the coil has not changed significantly, and most of the coil turns still maintain a good insulation state. Since the internal resistance mainly depends on the resistance of the coil wire itself and the influence of a few short-circuited coil turns is relatively small. Therefore, the measured magnetic pole internal resistance may still be within the normal range.

[0060] Based on this, the present application provides a method for measuring the life of the magnetic poles in a conventional high-speed magnetic levitation electromagnet. By obtaining parameters such as the measured magnetic pole field strength, the magnetic pole circulation time, the temperature of the magnetic pole after magnetic pole circulation, and the actual current value of the magnetic pole corresponding to multiple first positions in the magnetic pole, and combining the initial magnetic pole parameters to calculate the life evaluation coefficient, the working condition of the levitation electromagnet can be evaluated more comprehensively and accurately, effectively avoiding the missed judgment phenomenon caused by the small area of ​​​​damaged insulation layer.

[0061] To solve the above problems, the present invention provides a method for measuring the life of a magnetic pole in a high-speed magnetic levitation electromagnet. The following describes the method in detail with reference to the accompanying drawings.

[0062] Reference Figure 1 , Figure 1 A flow chart of a method for measuring the life of a magnetic pole in a high-speed magnetic levitation electromagnet provided in an embodiment of the present application is shown as follows: Figure 1As shown, a method for measuring the life of a magnetic pole in a high-speed magnetic levitation electromagnet provided in an embodiment of the present application may include steps S101 to S103, and these steps are described in detail below.

[0063] Step S101: Obtain measured magnetic pole parameters of the magnetic pole in the levitation electromagnet, wherein the measured magnetic pole parameters include measured magnetic pole field strengths corresponding to multiple first positions in the magnetic pole, magnetic pole flow time of the magnetic pole, temperature of the magnetic pole after magnetic pole flow, and actual current value of the magnetic pole after magnetic pole flow.

[0064] The magnetic pole flow time refers to the duration of current flowing through the magnetic pole coil of the levitation electromagnet when the magnetic pole is energized. For example, this can be measured using a high-precision time measuring instrument (such as an oscilloscope or time interval meter). The timer is started at the moment of power-on and stopped at the moment of power-off. The recorded time is the magnetic pole flow time.

[0065] The post-current temperature of the magnetic pole refers to the temperature reached by the magnetic pole of the suspended electromagnet after a period of power is applied due to the accumulation of heat generated by the current flowing through the coil. For example, this can be measured using a temperature sensor (such as a thermocouple or infrared thermometer). The temperature sensor is attached to the surface of the magnetic pole or embedded within the pole to monitor temperature changes in real time and record the temperature value after power is applied.

[0066] The actual current value refers to the current flowing through the levitation electromagnet coil, which is used to generate the magnetic field that levitates the maglev train. For example, a current sensor (such as a Hall effect current sensor or current transformer) can be used for measurement. The current sensor is connected in series to the levitation electromagnet's power supply circuit to monitor the current value in real time.

[0067] It can be understood that a levitation electromagnet includes multiple magnetic poles, and L magnetic poles constitute a magnetic pole group; the controller determines the actual current value of each magnetic pole group based on the weight of the train, and the actual current values ​​of different magnetic pole groups may be different or the same.

[0068] It is understandable that the actual current value is closely related to factors such as the levitation height of the maglev train, the load weight, the design parameters of the electromagnet, and the adjustment strategy of the control system.

[0069] Measuring magnetic field strength refers to the actual measurement of the magnetic field strength at a specific location on or near the surface of the magnetic pole of the levitating electromagnet. For example, this can be done using a magnetic field measuring instrument (such as a Gauss meter or Hall effect probe sensor). The probe is placed on or near the surface of the magnetic pole and the magnetic field strength value is read and recorded.

[0070] It is understandable that the magnitude of the measured magnetic pole field strength is affected by factors such as the levitation current value, the number of turns of the electromagnet coil, the magnetic circuit structure, the geometric shape of the magnetic pole, and the magnetic properties of the magnetic pole material.

[0071] Step S102: obtaining initial magnetic pole parameters of the magnetic pole, wherein the initial magnetic pole parameters include the theoretical magnetic pole field strength of the magnetic pole, the initial magnetic pole temperature of the magnetic pole, a preset temperature rise slope, and a theoretical levitation current value of the magnetic pole.

[0072] For example, a temperature sensor (such as a thermocouple, an infrared thermometer, etc.) may be used to measure the initial temperature (T0) of the magnetic pole when the magnetic pole is not powered or is not working.

[0073] For example, the manufacturer will provide the initial temperature of the magnetic pole (T0) when the product leaves the factory, which is usually obtained through experimental data under standard test conditions.

[0074] For example, under laboratory conditions, a power-on experiment is conducted on the magnetic poles of the levitation electromagnet, and a curve of the change in the magnetic pole temperature over time is recorded to calculate the expected temperature rise slope (a), which is usually between 0.007 and 0.015 degrees Celsius per second.

[0075] For example, the manufacturer will provide a preset temperature rise slope when the product leaves the factory, which is usually determined according to the material and design characteristics of the suspension electromagnet.

[0076] The temperature rise slope refers to the rate at which the temperature of the suspended electromagnet's magnetic poles rises over time during the power-on process, reflecting how quickly the magnetic poles heat up.

[0077] It's understandable that if there's hollowing between the magnetic pole surface resin encapsulation layer and the coil, the temperature rise rate is faster. The temperature rise slope can be used to determine whether there's hollowing between the magnetic pole encapsulation layer and the coil. If there's hollowing, heat dissipation is slow, and heat accumulates within the coil, potentially melting the magnetic pole surface resin encapsulation layer, leading to failure and potentially posing a safety risk.

[0078] For example, the technical documentation of a levitation electromagnet typically provides design parameters, including the theoretical magnetic pole field strength (B0). These parameters are derived based on the electromagnet's design specifications and theoretical calculations.

[0079] Step S103: obtaining a life evaluation coefficient of the magnetic pole based on the measured magnetic pole parameters and the initial magnetic pole parameters.

[0080] In an optional implementation, the temperature is a temperature at any second position in the magnetic pole, and obtaining the life evaluation coefficient of the magnetic pole based on the measured magnetic pole parameters and the initial magnetic pole parameters includes:

[0081] By formula: Calculating and obtaining the life evaluation coefficient;

[0082] Wherein, ε is the life evaluation coefficient, wherein B1-B n is the magnetic pole field strength corresponding to the multiple first positions in the magnetic pole, n is the number of the multiple first positions; B0 is the theoretical magnetic pole field strength; T0 is the initial temperature of the magnetic pole; Δt is the magnetic pole circulation time; T1 is the temperature; a is the expected temperature rise slope, a is 0.007-0.015; i0 is the actual current value; i is the theoretical suspension current value.

[0083] Exemplarily, this formula may be referred to as a field strength data analysis formula.

[0084] For example, the first weight, the second weight and the third weight can be determined based on actual conditions. For example, since the measured magnetic field strengths corresponding to the plurality of first positions are obtained, the obtained It is relatively accurate. Based on this, the first weight>the second weight≥the third weight.

[0085] For example, the first weight is 0.4, the second weight is 0.3, and the third weight is 0.3.

[0086] In an optional implementation, the temperature includes temperatures at a plurality of second positions in the magnetic pole, and obtaining the life evaluation coefficient of the magnetic pole based on the measured magnetic pole parameters and the initial magnetic pole parameters includes:

[0087] By formula:

[0088] Calculating and obtaining the life evaluation coefficient;

[0089] Wherein, ε is the life evaluation coefficient, wherein B1-B n is the magnetic field strength corresponding to the first positions of the magnetic pole, n is the number of the first positions; T1 to T m are the temperatures corresponding to the multiple second positions in the magnetic pole; m is the number of the multiple second positions; B0 is the theoretical magnetic pole field strength; T0 is the initial temperature of the magnetic pole; Δt is the magnetic pole circulation time; T1 is the temperature; a is the expected temperature rise slope, a is 0.007-0.015; i0 is the actual current value; i is the theoretical suspension current value.

[0090] For example, the first weight, the second weight and the third weight can be determined based on actual conditions. For example, since the temperatures corresponding to the plurality of second positions are measured, the obtained It is relatively accurate. Based on this, the first weight = the second weight > the third weight.

[0091] If the magnetic pole is damaged, the magnetic pole in the levitation electromagnet is replaced to extend the overall life of the levitation electromagnet.

[0092] The above-mentioned life evaluation coefficient ε can reflect the difference between the actual performance conditions of the levitation electromagnet and the theoretical performance that should be achieved. During the measurement process, if the calculated life evaluation coefficient ε reaches 40%, it means that the performance of the measured magnetic pole has lost 60%. At this time, it is a situation where the life span expires and needs to be replaced. The life evaluation coefficient ε can accurately reflect the working condition of the measured magnetic pole, provide an accurate reference for the actual operating condition of the magnetic pole, and reduce safety hazards during the operation of the maglev train.

[0093] For example, Wherein, μ0 is the vacuum magnetic permeability; i is the levitation current value of the levitation electromagnet; N is the number of turns of the coil of the levitation electromagnet; and z is the levitation gap between the levitation electromagnet and the maglev train.

[0094] The above formula is transformed into the formula: i=2zB0 / Nμ0, and the theoretical suspension current value can be calculated using the above formula.

[0095] Wherein, N is the number of turns of the suspension electromagnet coil, which can be set according to actual conditions; z is the suspension gap between the suspension electromagnet and the maglev train, which can be set to z=12.5 mm.

[0096] The above formula for obtaining the life evaluation coefficient of the magnetic pole can be seen. The above formula takes into account multiple measured magnetic pole fields. Strong Ping The difference between the mean and theoretical magnetic field strength. This factor takes into account the actual temperature rise of the levitation electromagnet's magnetic poles after power is applied (i.e., the temperature at the second location). The actual temperature rise difference measures the degree of difference between the temperature at each second location and T0 during the temperature rise of the levitation electromagnet's magnetic poles after power is applied.

[0097] The present application provides a method for measuring the life of the magnetic poles in a conventional high-speed maglev electromagnet. By obtaining parameters such as the measured magnetic pole field strength, the magnetic pole circulation time, the temperature of the magnetic pole after the magnetic pole circulation, and the actual current value of the magnetic pole corresponding to multiple first positions in the magnetic pole, and combining the initial magnetic pole parameters to calculate the life evaluation coefficient, the working condition of the levitation electromagnet can be more comprehensively and accurately evaluated, effectively avoiding the phenomenon of missed judgment caused by the small area of ​​insulation layer damage. By more accurately evaluating the working condition of the levitation electromagnet, problems such as abnormally low magnetic pole field strength can be discovered in a timely manner, so that measures can be taken in advance to avoid safety hazards such as damage to the insulation layer between coil turns, bulging and deformation of the resin encapsulation layer on the magnetic pole surface, and magnetic pole leakage caused by excessively high magnetic pole temperature, thereby ensuring the safe operation of the maglev vehicle and reducing the risk of accidents. The present application can accurately evaluate the service life of the magnetic pole. By calculating the life evaluation coefficient, operators can reasonably arrange the maintenance and replacement plan of the levitation electromagnet, carry out inspections or replace components at the appropriate time, avoid excessive wear or sudden failure of the magnetic pole, and avoid dangerous accidents.

[0098] Furthermore, based on detailed magnetic pole parameters and life evaluation coefficients, operators can conduct more refined maintenance management of the maglev train's levitation electromagnets. Electromagnets nearing the end of their lifespan can be prioritized for early attention and maintenance. For electromagnets in good working condition, maintenance cycles can be reasonably extended, reducing unnecessary maintenance work, improving efficiency, and lowering costs.

[0099] It is understandable that each carriage of the train may involve multiple magnetic poles, such as 174 magnetic poles in a carriage. In order to more accurately measure the magnetic field strength corresponding to the multiple second positions in each magnetic pole, the present application provides a measuring device.

[0100] like Figure 2The figure shows a schematic diagram of a measuring device for obtaining the measured magnetic pole parameters provided in an embodiment of the present application. The conventional high-speed magnetic levitation electromagnet magnetic pole measuring device provided in an embodiment of the present application includes an integrally formed measuring portion 100 and an abutting portion 200. The measuring portion 100 is used to fit with the top surface of the levitation electromagnet 400. The measuring portion 100 is provided with at least one measuring hole 101. The measuring hole 101 is used to install at least one measuring piece, which fits with the top surface of the levitation electromagnet 400 to measure the magnetic pole parameters of the magnetic pole in the levitation electromagnet 400. The abutting portion 200 extends from the end surface of the measuring portion 100 to the bottom surface of the levitation electromagnet 400, so that during the measurement process between the levitation electromagnet 400 and the levitation gap of the maglev train, the abutting portion 200 will not interfere with the levitation gap, so as to achieve The normal measurement operation of the measuring device is now shown; the abutment part 200 is used to abut against the peripheral side surface of the levitation electromagnet 400. There are at least two abutment parts 200, and at least two abutment parts 200 are arranged opposite to each other, so that the measuring device can be relatively fixed to the levitation electromagnet 400, so that the measuring part can stably measure the magnetic pole parameters of the levitation electromagnet 400. In this way, the working condition of the levitation electromagnet 400 is evaluated using the measured magnetic pole parameters, which improves the accuracy of the measurement of the working condition of the levitation electromagnet 400 and reduces the safety hazards during the operation of the maglev train.

[0101] For example, the measuring element can output a digital signal, which is transmitted to a data acquisition instrument via a data line and displayed as a corresponding numerical value after being analyzed. This numerical value can be used as a magnetic pole performance indicator after being calculated using a performance evaluation formula.

[0102] In actual situations, in order to facilitate the measurement of the suspension gap between the levitation electromagnet 400 and the maglev train, the thickness of the measuring part 100 is smaller than the suspension gap between the levitation electromagnet 400 and the maglev train. Generally, the suspension gap between the levitation electromagnet 400 and the maglev train is 10 mm. The thickness of the measuring part 100 can be adjusted according to actual conditions, and this embodiment of the present application does not limit this.

[0103] In some embodiments, the measuring part is a Hall probe sensor, which can measure the magnetic pole field strength, temperature and other parameters of the suspended electromagnet 400. It has high dynamic responsiveness, can capture rapidly changing field strength signals, has high accuracy and resolution, and can be applied to various environments such as high-temperature electromagnets, and can further improve the accuracy of measuring the suspended electromagnet 400.

[0104] In some other embodiments, the measuring piece can measure the temperature of the device by using a Hall probe sensor and a thermocouple probe sensor. Measuring the temperature rise of the magnetic pole of the suspended electromagnet 400, with high dynamic response, high measurement data accuracy and low cost and maintenance Simple.

[0105] In the measuring device provided in the embodiment of the present application, the measuring piece can be mounted and fixed to the measuring hole by bonding to ensure the stability of the measurement.

[0106] In some embodiments, the measuring portion 100 has a "cross"-shaped structure, and there are four abutment portions 200, which correspond one-to-one to the four end faces of the "cross"-shaped measuring portion 100, and the abutment portions 200 correspond one-to-one to the peripheral side surfaces of the levitation electromagnet 400, so that the abutment portions 200 can relatively fix the measuring device and the levitation electromagnet 400.

[0107] In some other embodiments, such as Figures 4 and 5 As shown, the measuring portion 100 has a "large"-shaped structure, and there are five abutment portions 200, which correspond one-to-one to the five end surfaces of the measuring portion 100 of the "large"-shaped structure, and two abutment portions 200 correspond to one circumferential side surface of the levitation electromagnet 400, so as to further improve the connection strength between the abutment portions 200 and the levitation electromagnet 400.

[0108] In some other embodiments, the number of the abutting portions 200 may be six, seven, eight, or the like, which is a corresponding number that can abut against the peripheral side surface of the levitation electromagnet 400 . This embodiment of the present application does not limit this.

[0109] In some embodiments, as Figure 6 As shown, the measuring portion 100 can be an integral surface structure capable of covering a portion of the measuring surface of the levitation electromagnet 400, and there can be two abutting portions 200, one of which is close to the manual measuring position as the first abutting portion 210, and the other abutting portion 200 can abut the adjacent circumferential side surface of the levitation electromagnet 400 corresponding to the first abutting portion 210, so as to reduce the configuration of the abutting portion 200, so as to facilitate the testing of multiple adjacent levitation electromagnets 400. At the same time, by abutting the two adjacent circumferential side surfaces of the levitation electromagnet 400, the size restriction of the adaptable levitation electromagnet 400 is reduced, thereby improving the applicability of the measuring device.

[0110] like Figures 5 to 7 As shown, in the abutment portion 200, the abutment portion 200 close to the manual measurement position is the first abutment portion 210, wherein the manual measurement position is the standing area of ​​the staff during the actual measurement process, and the manual measurement position corresponds to the side of the suspended electromagnet 400 close to the outside, so that the staff can measure the suspended electromagnet 400.

[0111] For ease of operation, Figures 2 to 5 As shown, the first abutting portion 210 is connected to a handheld portion 300 , so that a worker can hold the measuring device through the handheld portion 300 , thereby improving the convenience of the measuring process.

[0112] like Figure 4As shown, the measuring part 100 is further provided with a wire groove 102, which connects the measuring hole 101 and the first abutting portion 210, and the wire groove 102 extends along the length direction of the suspended electromagnet 400, so that after the measuring piece is installed in the measuring hole 101, the connecting wire of the measuring piece can be connected to the external device through the wire groove 102, thereby reducing the interference of the connecting wire of the measuring piece on the measurement process and further improving the accuracy of the measurement of the suspended electromagnet 400.

[0113] In order to further improve the stability of the connection between the measuring device and the suspension electromagnet 400, a limit block 201 is provided at one end of at least one abutting portion 200 away from the measuring portion 100. The limit block 201 can cooperate with the bottom surface of the suspension electromagnet 400 to further improve the stability of the connection between the measuring device and the suspension electromagnet 400.

[0114] For example, Figure 3 As shown, a limit block 201 is provided at one end of the first abutting portion 210 away from the measuring portion 100 , so that the limit block 201 can cooperate with the bottom surface of the suspension electromagnet 400 to further improve the connection stability between the measuring device and the suspension electromagnet 400 .

[0115] It should be noted that in order to ensure that the measuring device can enter the suspension gap between the suspension electromagnet 400 and the maglev train for measurement, the overall thickness of the abutment portion 200 and the measuring portion 100, which are arranged opposite to the first abutment portion 210 and away from the manual measurement position, should be smaller than the suspension gap between the suspension electromagnet 400 and the maglev train, so as to ensure that the measuring device can perform normal measurement operations during the actual measurement process.

[0116] In the measuring device provided in the embodiment of the present application, the entire material of the measuring device is a non-magnetic material, and the magnetic permeability of the measuring device is basically consistent with or close to the magnetic permeability of air, so as to reduce the influence of the measuring device on the magnetic poles of the levitation electromagnet 400 during the measurement process, and improve the accuracy of the magnetic pole measurement of the levitation electromagnet 400.

[0117] In some embodiments, the measuring device is made of polylactic acid (PLA), which has non-magnetic interference, can ensure measurement accuracy, is easy to process and shape, can be applied to suspension electromagnets 400 of various sizes, and improves the stability of the connection with the suspension electromagnet 400.

[0118] In some other embodiments, the material of the measuring device is G10 resin, which is a composite of epoxy resin and glass fiber. It has non-magnetic interference, can ensure the accuracy of measurement, has high compressive and bending strength, is suitable for rigid support of precision measuring equipment, and has extremely small deformation during temperature fluctuations, which can further improve the accuracy of measurement of the suspended electromagnet 400. It is easy to process and can be applied to suspended electromagnets 400 of multiple sizes, thereby improving the stability of the connection with the suspended electromagnet 400.

[0119] When the measuring device provided in the embodiment of the present application is in operation, the measuring piece is installed and matched with the measuring hole 101 of the measuring part 100, and then the measuring part 100 is fitted with the top surface of the levitation electromagnet 400 so that the measuring piece is fitted with the levitation electromagnet 400, and the abutting part 200 is abutted against the peripheral side surface of the levitation electromagnet 400 in a one-to-one correspondence, completing the relative fixation of the measuring device and the levitation electromagnet 400, and then the magnetic pole parameters of the levitation electromagnet 400 are measured by the measuring piece, and the magnetic pole parameters are collected by the collection unit, and the life evaluation coefficient ε of the levitation electromagnet 400 is obtained by the calculation unit. Through the life evaluation coefficient ε, the actual working condition and life of the levitation electromagnet 400 can be obtained, thereby improving the accuracy of the working condition measurement of the levitation electromagnet 400 and reducing the safety hazards during the operation of the maglev train.
