Description

Technical Field

[0001] This application relates to the field of maglev train technology, and in particular to a method and device for measuring the lifespan of magnetic poles in a conventional high-speed maglev levitation electromagnet. Background Technology

[0002] Conventional high-speed maglev trains utilize the electromagnetic attraction between ordinary DC electromagnets and highly conductive magnetic materials, employing automatic closed-loop control to achieve train levitation and guidance. They feature a small levitation air gap, typically around 10 millimeters, and can reach speeds of 400–500 km / h, making them ideal for long-distance rapid transportation between cities. The levitation electromagnet is one of the core components of conventional high-speed maglev trains. It generates electromagnetic attraction through interaction with the ferromagnetic materials on the track, leviting the train above the track.

[0003] A levitation electromagnet consists of components such as a coil and an iron core. If the magnetic poles of a levitation electromagnet are damaged, such as by a short circuit between turns or by damage to the insulation layer between the turns of the coil, it can cause some turns of the coil to conduct, potentially leading to leakage current in the magnetic poles and causing a safety accident.

[0004] Therefore, how to measure whether the magnetic poles in a levitation electromagnet are damaged is a difficult problem to be solved in this field. Summary of the Invention

The measuring hole is used to install at least one measuring piece. The measuring piece fits with the suspended electromagnet (400) to measure the magnetic pole parameters of the suspended electromagnet;

[0022] The abutting part extends from the end surface of the measuring part to the bottom surface of the suspended electromagnet. The abutting part is used to abut against the circumferential side surface of the suspended electromagnet. There are at least two abutting parts. At least two abutting parts are arranged oppositely, so that the measuring device can be relatively fixed with the suspended electromagnet.

[0023] In a possible implementation, there are two abutting parts. One of the abutting parts close to the manual measurement position is the first abutting part. The other abutting part is used to abut against the adjacent circumferential side surface of the circumferential side surface of the suspended electromagnet corresponding to the first abutting part.

[0024] In a possible implementation, the measuring part is further provided with a wire groove. The wire groove communicates the measuring hole and the first abutting part, and the wire groove extends along the length direction of the suspended electromagnet.

[0025] In a possible implementation, a limiting block is arranged at one end of at least one abutting part far from the measuring part. The limiting block is used for limiting cooperation with the bottom surface of the suspended electromagnet.

[0029] In a possible implementation, the first abutting part is connected with a handheld part.

[0030] The second aspect of the present application provides a device for measuring the life of magnetic poles in a normally-conductive high-speed maglev suspended electromagnet, including:

[0031] A first acquisition module, configured to acquire the measured magnetic pole parameters of the magnetic poles in the suspended electromagnet. The measured magnetic pole parameters include the measured magnetic pole field strengths respectively corresponding to multiple first positions in the magnetic poles, the magnetic pole circulation time of the magnetic poles, the temperature after the magnetic pole circulation of the magnetic poles, and the actual current value after the magnetic pole circulation of the magnetic poles;

[0039] By employing the above technical solution, this application provides a method for measuring the lifespan of magnetic poles in a conventional high-speed maglev levitation electromagnet. By acquiring parameters such as the measured magnetic field strength, magnetic pole flow time, magnetic pole temperature after flow, and actual current value at multiple first positions of the magnetic pole, and combining these with initial magnetic pole parameters to calculate a lifespan evaluation coefficient, the operating condition of the levitation electromagnet can be assessed more comprehensively and accurately, effectively avoiding missed assessments due to small areas of insulation layer damage. Through more accurate assessment of the levitation electromagnet's operating condition, problems such as abnormally low magnetic field strength can be detected in a timely manner, allowing for proactive measures to prevent safety hazards such as coil inter-turn insulation layer damage, bulging and deformation of the resin encapsulation layer on the magnetic pole surface, and magnetic pole leakage caused by excessively high magnetic pole temperatures. This ensures the safe operation of maglev vehicles and reduces the risk of accidents. This application can accurately assess the service life of the magnetic poles. By calculating the service life evaluation coefficient, operators can reasonably arrange the maintenance and replacement plan of the levitation electromagnet, and carry out maintenance or replacement of the magnetic poles at the appropriate time to avoid excessive wear or sudden failure of the levitation electromagnet, thereby extending the service life of the levitation electromagnet and improving its reliability and economy.

[0040] Furthermore, based on detailed magnetic pole parameters and lifespan evaluation coefficients, operators can perform more refined maintenance and management of the levitation electromagnets of maglev trains. For magnetic poles nearing the end of their lifespan, they can be given priority attention and maintenance in advance; for magnetic poles in good working condition, the maintenance cycle can be reasonably extended, reducing unnecessary maintenance work, improving maintenance efficiency, and lowering maintenance costs.

[0053] The embodiments of this application are described below with reference to the accompanying drawings. The terminology used in the implementation section of this application is for explaining specific embodiments only and is not intended to limit the scope of this application.

[0054] The embodiments of this application will now be described with reference to the accompanying drawings. Those skilled in the art will recognize that, with technological advancements and the emergence of new scenarios, the technical solutions provided in the embodiments of this application are equally applicable to similar technical problems.

[0055] The terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such terms are interchangeable where appropriate; this is merely a way of distinguishing objects with the same attributes in the embodiments of this application. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion, so that a process, method, system, product, or apparatus that comprises a series of elements is not necessarily limited to those elements, but may include other elements not explicitly listed or inherent to those processes, methods, products, or apparatuses.

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

[0057] Due to copper and iron losses, the temperature of the magnetic poles in levitation electromagnets can rise. If the pole temperature becomes too high, it may damage the insulation layer between the coil turns, resulting in an abnormally low electric field strength, which could affect the safe operation of maglev vehicles. Furthermore, prolonged high pole temperatures can cause the resin encapsulation layer on the pole surface to bulge and deform, making heat dissipation difficult. If the insulation layer is damaged, it could lead to magnetic pole leakage, posing a safety risk.

[0058] In related technologies, the method of measuring the internal resistance of the magnetic poles in a levitation electromagnet is used to determine whether an inter-turn short circuit fault has occurred in the poles. This is because the internal resistance of the magnetic poles of a levitation electromagnet is determined by the resistance of its coil. Under normal circumstances, the inter-turn insulation layer of the coil is intact, and the internal resistance is mainly determined by the resistance of the wires, resulting in a relatively stable internal resistance value. When an inter-turn short circuit occurs in the poles, the inter-turn insulation layer of the coil is damaged, causing some coil turns to conduct. In this case, the effective conduction path of the coil changes, and the internal resistance will decrease significantly.

[0059] During the research process, the applicant discovered that the accuracy of the relevant technology was not high for the following reasons: When the damaged area of ​​the inter-turn insulation layer of the magnetic pole coil is small, only the insulation performance between a few coil turns may decrease. In this case, the magnetic field strength decreases, requiring a larger current to increase the magnetic field strength. Increasing the current aggravates the magnetic pole damage, posing a safety risk. If only the insulation performance between a few coil turns decreases, the overall conductive path of the coil does not change significantly, and most coil turns still maintain good insulation. 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, the measured magnetic pole internal resistance may still be within the normal range.

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

[0061] To address the aforementioned problems, this application provides a method for measuring the lifespan of magnetic poles in a conventional high-speed maglev levitation electromagnet. The method for measuring the lifespan of magnetic poles in a conventional high-speed maglev levitation electromagnet according to this application will be described in detail below with reference to the accompanying drawings.

[0062] Reference Figure 1 , Figure 1 A flowchart illustrating a method for measuring the lifespan of magnetic poles in a conventional high-speed magnetic levitation electromagnet, as provided in this application embodiment, is shown below. Figure 1As shown in the embodiment of this application, a method for measuring the lifespan of magnetic poles in a conventional high-speed magnetic levitation electromagnet may include steps S101 to S103, which are described in detail below.

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

[0064] The magnetic pole flow time refers to the duration for which current flows through the magnetic pole coil of a levitated electromagnet when the poles are energized. For example, it can be measured using a high-precision time measuring instrument (such as an oscilloscope or time interval meter). Timing starts the instant energization is applied and stops the instant energization is removed; the recorded time is the magnetic pole flow time.

[0065] The temperature after energization refers to the temperature reached by the magnetic poles of a levitated electromagnet after a period of time due to the heat accumulated from the current flowing through the coil. For example, a temperature sensor (such as a thermocouple or infrared thermometer) can be used for measurement. The temperature sensor is attached to the surface of the magnetic pole or embedded inside it to monitor temperature changes in real time and record the temperature value after energization.

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

[0067] Understandably, a levitation electromagnet consists of multiple magnetic poles, with L magnetic poles forming a magnetic pole group. The controller determines the actual current value for each magnetic pole group based on the weight of the train, and the actual current values ​​for different magnetic pole groups may be different or the same.

[0068] Understandably, 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 pole field strength refers to the actual measurement of the magnetic field strength at or near the surface of the magnetic poles of a levitated electromagnet. For example, this can be done using magnetic field measuring instruments (such as a gaussmeter, Hall effect sensor, etc.). The probe is placed on or near the magnetic pole surface, and the magnetic field strength value is read and recorded.

[0070] It is understandable that the magnitude of the 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 geometry of the magnetic pole, and the magnetic properties of the magnetic pole material.

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

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

[0073] For example, manufacturers provide the initial magnetic pole temperature (T0) when the product leaves the factory, which is usually derived from experimental data under standard test conditions.

[0074] For example, under laboratory conditions, an experiment is conducted on the poles of a levitation electromagnet to conduct an energization test, and the temperature change curve of the poles over time is recorded to calculate the desired temperature rise slope (a). This slope is typically between 0.007 and 0.015 degrees Celsius per second.

[0075] For example, manufacturers provide a preset temperature rise slope when the product leaves the factory, which is usually determined based on the material and design characteristics of the levitation electromagnet.

[0076] The temperature rise slope refers to the rate at which the temperature of a suspended electromagnet pole rises over time during the energization process, reflecting the speed at which the pole heats up.

[0077] Understandably, if there is a void between the resin encapsulation layer on the magnetic pole surface and the coil, the temperature rise rate will be faster. The presence of a void between the encapsulation layer and the coil can be determined based on the temperature rise slope. If a void exists, the heat dissipation rate is slow, and heat accumulates inside the coil, which can easily cause the resin encapsulation layer on the magnetic pole surface to melt, leading to its failure and posing a safety risk.

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

[0079] Step S103: Based on the measured magnetic pole parameters and the initial magnetic pole parameters, obtain the lifetime evaluation coefficient of the magnetic pole.

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

[0081] Through the formula: The life evaluation coefficient is calculated.

[0082] Where ε is the life evaluation coefficient, and B1-B n denoted by n, where n is the number of the plurality of first positions; B0 is the theoretical magnetic field strength; T0 is the initial temperature of the magnetic pole; Δt is the magnetic pole flow time; T1 is the temperature; a is the desired temperature rise slope, where a is 0.007-0.015; i0 is the actual current value; and i is the theoretical levitation current value.

[0083] For example, this formula can be called the field strength data analysis formula.

[0084] For example, the first weight, second weight, and third weight can be determined based on the actual situation. For example, since the measured magnetic field strengths corresponding to multiple first positions are obtained, the obtained... This 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 one alternative implementation, the temperature includes the temperature at multiple second locations within the magnetic pole, and obtaining the lifetime evaluation coefficient of the magnetic pole based on the measured magnetic pole parameters and the initial magnetic pole parameters includes:

[0087] Through the formula:

[0088] The life evaluation coefficient is calculated.

[0089] Where ε is the life evaluation coefficient, and B1-B n Let n be the magnetic field strength corresponding to the plurality of first positions in the magnetic poles, and n be the number of the plurality of first positions; T1 to T m The values ​​are: t = m, d = t ...

[0090] For example, the first weight, second weight, and third weight can be determined based on the actual situation. For example, since the temperature corresponding to multiple second positions is measured, the obtained... This 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 can be changed to extend the overall lifespan of the levitation electromagnet.

[0092] The aforementioned life evaluation coefficient ε can reflect the difference between the actual performance of the levitation electromagnet and the theoretically expected performance. During the measurement process, if the calculated life evaluation coefficient ε reaches 40%, it means that the performance of the measured magnetic pole has been lost by 60%, which means that the life has expired and needs to be replaced. The life evaluation coefficient ε can accurately reflect the working condition of the measured magnetic pole, providing an accurate reference for the actual operating condition of the magnetic pole and reducing safety hazards during the operation of the maglev train.

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

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

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

[0096] As can be seen from the formula for obtaining the lifetime evaluation coefficient of the magnetic poles, the formula takes into account multiple measured magnetic pole fields. Strong Ping The difference between the mean and the theoretical magnetic field strength. The actual temperature rise difference after the magnetic poles of the levitation electromagnet are energized (i.e., the temperature at the second position) is considered. The actual temperature rise difference measures the degree of difference between the temperature at each second position and T0 during the temperature rise process of the levitation electromagnet's poles after energization.

[0097] This application provides a method for measuring the lifespan of magnetic poles in a conventional high-speed maglev levitation electromagnet. By acquiring parameters such as the measured magnetic field strength, magnetic pole flow time, magnetic pole temperature after flow, and actual current value at multiple first positions of the magnetic pole, and combining these parameters with the initial magnetic pole parameters to calculate a lifespan evaluation coefficient, the operating condition of the levitation electromagnet can be assessed more comprehensively and accurately, effectively avoiding missed assessments due to small areas of insulation layer damage. By more accurately assessing the operating condition of the levitation electromagnet, abnormally low magnetic field strength can be detected in a timely manner, allowing for proactive measures to prevent safety hazards such as coil inter-turn insulation layer damage, resin encapsulation layer bulging and deformation on the magnetic pole surface, and magnetic pole leakage caused by excessively high magnetic pole temperatures. This ensures the safe operation of the maglev vehicle and reduces the risk of accidents. This application can accurately assess the lifespan of the magnetic poles. By calculating the lifespan evaluation coefficient, operators can rationally plan the maintenance and replacement of the levitation electromagnet, performing repairs or replacing components at appropriate times to avoid excessive wear or sudden failures of the magnetic poles and prevent dangerous accidents.

[0098] Furthermore, based on detailed magnetic pole parameters and lifespan evaluation coefficients, operators can perform more refined maintenance and management of the levitation electromagnets in maglev trains. For electromagnets nearing the end of their lifespan, they can receive focused attention and maintenance in advance; for electromagnets in good working condition, the maintenance cycle can be reasonably extended, reducing unnecessary maintenance work, improving maintenance efficiency, and lowering maintenance costs.

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

[0100] like Figure 2The diagram shows a schematic of a measuring device for obtaining the measured magnetic pole parameters provided in an embodiment of this application. The magnetic pole measuring device for a conventional high-speed maglev levitation electromagnet provided in this embodiment includes an integrally formed measuring part 100 and a contact part 200. The measuring part 100 is used to contact the top surface of the levitation electromagnet 400. The measuring part 100 has at least one measuring hole 101 for mounting at least one measuring element. The measuring element contacts the top surface of the levitation electromagnet 400 to measure the magnetic pole parameters of the magnetic poles in the levitation electromagnet 400. The contact part 200 extends from the end face of the measuring part 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 contact part 200 will not interfere with the levitation gap, thus achieving... The measuring device is currently performing normal measurement operations. The contact part 200 is used to contact the peripheral side of the levitation electromagnet 400. There are at least two contact parts 200, and the at least two contact parts 200 are arranged opposite to each other, so that the measuring device can be relatively fixed with the levitation electromagnet 400. This allows the measuring element to stably measure the magnetic pole parameters of the levitation electromagnet 400. In this way, the operating condition of the levitation electromagnet 400 is evaluated using the measured magnetic pole parameters, which improves the accuracy of the operating condition measurement of the levitation electromagnet 400 and reduces safety hazards during the operation of the maglev train.

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

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

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

[0104] In other embodiments, the measuring element is measured collaboratively by a Hall effect sensor and a thermocouple sensor, enabling... The method for measuring the pole temperature rise of a 400-type levitation electromagnet exhibits high dynamic response, high accuracy of measurement data, and low cost and maintenance. Simple.

[0105] In the measuring device provided in the embodiments of the present application, the measuring piece can be fixedly installed with the measuring hole by bonding to ensure the stability of measurement.

[0106] In some embodiments, the measuring part 100 has a "cross" - shaped structure, and there are four abutting parts 200, which correspond one - to - one to the four end faces of the "cross" - shaped measuring part 100, and the abutting parts 200 correspond one - to - one to the circumferential side surface of the suspended electromagnet 400, so that the abutting parts 200 can relatively fix the measuring device and the suspended electromagnet 400.

[0107] In some other embodiments, as Figures 4 to 5 shown, the measuring part 100 has a "big" - shaped structure, and there are five abutting parts 200, which correspond one - to - one to the five end faces of the "big" - shaped measuring part 100, and two abutting parts 200 correspond to one circumferential side surface of the suspended electromagnet 400, so as to further improve the connection strength between the abutting part 200 and the suspended electromagnet 400.

[0108] In some other embodiments, the abutting part 200 can also be six, seven, eight, etc., which can be in a number corresponding to the circumferential side surface of the suspended electromagnet 400 for abutting, and the embodiments of the present application do not limit this.

[0109] In some embodiments, as Figure 6 shown, the measuring part 100 can be an integral surface structure that can cover a part of the measuring surface of the suspended electromagnet 400, and there are two abutting parts 200. One abutting part 200 close to the manual measurement position is the first abutting part 210, and the other abutting part 200 can abut against the adjacent circumferential side surface of the circumferential side surface of the suspended electromagnet 400 corresponding to the first abutting part 210, so as to reduce the configuration of the abutting part 200, facilitate the testing of multiple closely adjacent suspended electromagnets 400, and at the same time, by abutting against two adjacent circumferential side surfaces of the suspended electromagnet 400, the size limitation of the suspended electromagnet 400 that can be adapted is reduced, and the applicability of the measuring device is improved.

[0110] As Figures 5 to 7 shown, in the abutting part 200, the abutting part 200 close to the manual measurement position is the first abutting part 210. Among them, 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 as to facilitate the staff to measure the suspended electromagnet 400.

[0111] For the convenience of operation, as Figures 2 to 5 shown, the first abutting part 210 is connected with a handheld part 300, so that the staff can hold the measuring device through the handheld part 300, improving the convenience of the measurement process.

[0112] As Figure 4As shown, the measuring unit 100 also has a wire groove 102, which connects the measuring hole 101 and the first abutment part 210. The wire groove 102 extends along the length of the levitation electromagnet 400 so that after the measuring component is installed in the measuring hole 101, the connecting wire of the measuring component can be connected to the external device through the wire groove 102, reducing the interference of the connecting wire of the measuring component to the measurement process and further improving the accuracy of the measurement of the levitation electromagnet 400.

[0113] To further improve the stability of the connection between the measuring device and the levitation electromagnet 400, a limiting block 201 is provided at at least one end of the contact portion 200 away from the measuring portion 100. The limiting block 201 can be matched with the bottom surface of the levitation electromagnet 400 to further improve the stability of the connection between the measuring device and the levitation electromagnet 400.

[0114] For example, such as Figure 3 As shown, a limiting block 201 is provided at the end of the first contact portion 210 away from the measuring portion 100, so that the limiting block 201 can be matched with the bottom surface of the levitation electromagnet 400 to further improve the connection stability between the measuring device and the levitation electromagnet 400.

[0115] It should be noted that, in order to ensure that the measuring device can enter the suspension gap between the levitation electromagnet 400 and the maglev train for measurement, the overall thickness of the contact part 200 and the measuring part 100, which are opposite to the first contact part 210 and far from the manual measurement position, should be less than the suspension gap between the levitation 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 this application embodiment, the measuring device as a whole is made of non-magnetic material, and the magnetic permeability of the measuring device is basically the same as 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 the accuracy of measurement, is easy to process and mold, can be applied to multiple sizes of levitation electromagnets 400, and improves the stability of the connection with the levitation electromagnet 400.

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

[0119] When the measuring device provided in this application embodiment is in operation, the measuring component is installed and fitted with the measuring hole 101 of the measuring part 100. Then, the measuring part 100 is attached to the top surface of the levitation electromagnet 400 so that the measuring component and the levitation electromagnet 400 are attached. The abutting part 200 abuts against the peripheral side surface of the levitation electromagnet 400 one by one, thus completing the relative fixation of the measuring device and the levitation electromagnet 400. Then, the magnetic pole parameters of the levitation electromagnet 400 are measured by the measuring component, and the magnetic pole parameters are collected by the acquisition unit. 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, which improves the accuracy of the working condition measurement of the levitation electromagnet 400 and reduces the safety hazards during the operation of the maglev train.
