Description

Technical Field

[0001] This invention relates to the field of power equipment operating parameter measurement and testing technology, and in particular to an operating parameter measurement and testing device and method for dry-type reactors. Background Technology

[0002] Currently, dry-type reactors, as the core reactive power compensation equipment in ultra-high voltage (UHV) power transmission networks, have significant advantages over traditional oil-immersed reactors, including simple insulation structure, oil-free fire prevention, low operating noise, convenient maintenance, and strong environmental adaptability. They can effectively avoid safety hazards such as oil leakage, explosion, and environmental pollution associated with oil-immersed equipment. Dry-type reactors are one of the mainstream choices for oil-free upgrades and replacements of UHV parallel reactors and are widely used in key scenarios such as reactive power regulation, voltage stabilization, and harmonic suppression in power grids, playing a crucial role in ensuring the stable operation of UHV power grids.

[0003] However, dry-type reactors operate entirely exposed in the outdoor atmosphere, enduring complex and variable operating conditions over long periods. Their insulation system is susceptible to corrosion from a combination of internal and external factors. Specifically, the reactor's continuous current flow generates Joule heat, causing a sustained increase in the reactor's temperature and resulting in aging and performance degradation of the insulation materials. Simultaneously, external environmental factors such as humidity, rain, condensation, and dust continuously penetrate the insulation structure, causing the insulation materials to become damp and contaminated. Under the long-term combined stress of electric field, thermal field, moisture, and contamination, the core insulation performance of dry-type reactors, such as insulation resistance and withstand voltage, continuously deteriorates, significantly reducing the insulation margin and potentially leading to insulation breakdown and failure.

[0004] Furthermore, insulation failure can directly induce severe equipment malfunctions in dry-type reactors, such as inter-turn short circuits, partial discharges, and overheating fires. This not only causes damage to individual units and power outages but also easily triggers regional power grid voltage fluctuations and harmonic exceedances, seriously threatening the safe, stable, and reliable operation of ultra-high voltage (UHV) power systems and causing huge economic losses and power supply security risks to power grid companies. Therefore, real-time and accurate acquisition of key state parameters such as electric field, magnetic field, operating current, operating voltage, and body temperature during the operation of dry-type reactors, and dynamic monitoring of equipment operating conditions and insulation status, has extremely important engineering value for predicting potential equipment failures, avoiding severe accidents, and ensuring the safe operation of equipment and the power grid.

[0005] Currently, there are still significant shortcomings and technical deficiencies in the operation monitoring technology for dry-type reactors. Existing live-line detection and condition monitoring methods are relatively simple and lack sufficient intelligence. The industry currently relies heavily on traditional methods such as periodic power outage inspections, manual infrared thermography, and offline insulation testing, lacking a comprehensive, 24 / 7 live-line real-time monitoring system. Traditional detection methods not only fail to achieve real-time continuous acquisition of reactor operating parameters, resulting in problems such as detection lag, low accuracy, and large errors due to human intervention, but also struggle to accurately capture subtle parameter fluctuations and early latent fault characteristics during equipment operation. Furthermore, existing monitoring technologies cannot simultaneously couple and analyze multi-dimensional state quantities such as electric field, magnetic field, temperature and humidity, and electrical parameters, making it difficult to accurately determine the degree of insulation aging and fault development trends. This hinders effective support for dry-type reactor condition assessment, fault early warning, and condition-based maintenance, failing to meet the actual needs of ultra-high voltage and extra-high voltage power grids for highly reliable and intelligent operation and maintenance of dry-type reactors.

[0006] In summary, developing a technical solution that enables real-time and accurate monitoring of multi-dimensional operating parameters of dry-type reactors to overcome the shortcomings of existing monitoring technologies is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0011] Preferably, the operating parameter measurement and testing device for dry-type reactors provided by the present invention includes an internal non-electrical parameter measurement component comprising an insulating support rod, an insulating mounting frame, and multiple temperature sensors. The bottom end of the insulating support rod is slidably connected to the annular insulating guide rail. The insulating mounting frame is slidably mounted on the outer wall of the insulating support rod and can slide along the centerline of the insulating support rod to adjust the height of the insulating mounting frame. Multiple temperature sensors are spaced apart on the insulating mounting frame, and all multiple temperature sensors are wirelessly connected to the remote device.

[0012] Preferably, the operating parameter measurement and testing device for dry-type reactors provided by the present invention includes an insulating mounting frame comprising a transverse insulating rod and a mounting rod. The transverse insulating rod is slidably connected to the insulating support rod, and the transverse insulating rod can slide along the centerline of the insulating support rod. The top end of the mounting rod is slidably connected to the transverse insulating rod, and the mounting rod can slide along the centerline of the transverse insulating rod. The centerline of the mounting rod is parallel to the centerline of the insulating support rod. A plurality of temperature sensors are spaced apart on the mounting rod. By vertically sliding the transverse insulating rod and horizontally adjusting the position of the mounting rod, the temperature sensors on the mounting rod can be inserted into the gas passage of the dry-type reactor to be measured to measure the internal temperature distribution.

[0013] Preferably, the dry-type reactor operation parameter measurement test device provided by the present invention includes a remote device comprising a wireless receiving device and a host computer.

The host computer is used to realize data reception, storage, analysis, and remote control of the equipment.

[0014] On the other hand, the present invention provides a measurement and testing method using the operating parameter measurement and testing device for a dry-type reactor as described above, comprising the following steps: Based on the dimensions of the dry-type reactor to be measured, electromagnetic field / potential integrated sensors are installed on the insulating components of the external electrical parameter measurement components at preset intervals, and temperature sensors are installed on the insulating mounting frame of the internal non-electrical parameter measurement components at predicted intervals. The external electrical parameter measuring component and the internal non-electrical parameter measuring component are remotely controlled by the host computer in the remote device to slide along the annular insulated guide rail to the preset measurement position, and the height and lateral position calibration are completed respectively, so that each sensor is aligned with the preset measurement point of the dry reactor to be measured. The rated voltage and rated current are applied to the dry-type reactor under test, and a complex operating environment is simulated. All sensors synchronously collect multi-dimensional operating parameters of the dry-type reactor under test in real time and wirelessly transmit them to a remote device.

[0016] Preferably, in the measurement and testing method provided by the present invention, the range of the predicted spacing is 0.2m-0.4m.

[0017] Preferably, the measurement and testing method provided by the present invention involves remotely controlling the external electrical parameter measuring component and the internal non-electrical parameter measuring component to slide along the annular insulated guide rail to a preset measurement position via a host computer in a remote device, and performing height and lateral position calibrations respectively, so that each sensor is aligned with the preset measurement point of the dry-type reactor to be measured, including: When the internal non-electrical parameter measurement component is adjusted, the transverse insulating rod in the internal non-electrical parameter measurement component is slid upward along the center line of the insulating support rod in the internal non-electrical parameter measurement component. The transverse insulating rod drives the mounting rod in the internal non-electrical parameter measurement component and the temperature sensor in the internal non-electrical parameter measurement component to move upward to a position higher than the top of the dry reactor to be measured. The mounting rod is slid along the center line of the transverse insulating rod to a preset position to complete the transverse alignment. Then, the transverse insulating rod is slid downward along the center line of the insulating support rod so that the temperature sensor is placed inside the air passage of the dry reactor to be measured and fits against the outer wall of the enclosure. When the external electrical parameter measurement component is adjusted, the first horizontal insulating rod in the external electrical parameter measurement component is slid vertically to a first predetermined height, and the second horizontal insulating rod in the external electrical parameter measurement component is slid vertically to a second predetermined height. This causes the integrated electromagnetic field / potential sensor on the first horizontal insulating rod to be in contact with the top surface of the dry-type reactor to be measured, and the integrated electromagnetic field / potential sensor on the second horizontal insulating rod to be in contact with the bottom surface of the dry-type reactor to be measured. At the same time, the integrated electromagnetic field / potential sensor on the vertical insulating rod in the external electrical parameter measurement component is in contact with the outer surface of the dry-type reactor to be measured, thereby completing the alignment of the electrical parameter measurement points in multiple areas on the top, outer, and bottom surfaces of the dry-type reactor to be measured.

[0018] In summary, the beneficial technical effects of this invention are as follows: The beneficial technical effects of the dry-type reactor operation parameter measurement test device and measurement test method provided in this application are as follows: 1. By setting up a wireless communication connection between the measurement equipment and the remote equipment, the complexity of laying a large number of cables is avoided, and the safety of high-voltage testing is improved; 2.

[0023] The present invention will be further described in detail below with reference to the accompanying drawings.

[0024] First embodiment: Reference Figure 1This invention discloses a test device 1 for measuring the operating parameters of a dry-type reactor, comprising a measuring device 10 and a remote device 20. The measuring device 10 includes an external electrical parameter measuring component 11, an internal non-electrical parameter measuring component 12, and an annular insulated rail 13. The bottom ends of both the external electrical parameter measuring component 11 and the internal non-electrical parameter measuring component 12 are slidably connected to the annular insulated rail 13. The dry-type reactor 2 to be measured is arranged in the middle of the annular insulated rail 13. Both the external electrical parameter measuring component 11 and the internal non-electrical parameter measuring component 12 are wirelessly connected to the remote device 20. The external electrical parameter measuring component 11 is used for measuring the operating parameters of the reactor. The surface electric field, spatial magnetic field, and potential distribution of the dry-type reactor 2 are measured during operation. The internal non-electrical parameter measurement component 12 is used to measure the internal temperature distribution of the gas duct 206 of the dry-type reactor 2 under test. By setting the external electrical parameter measurement component 11 and the internal non-electrical parameter measurement component 12, the external electrical parameter measurement component 11 and the internal non-electrical parameter measurement component 12 work together to synchronously collect multi-dimensional core parameters such as electric field, magnetic field, potential, and internal temperature during the operation of the dry-type reactor, obtain the real-time status of the dry-type reactor operation, ensure the safe and stable operation of the equipment, and solve the problems of single measurement dimension and incomplete point coverage in the existing technology.

[0025] For details, see Figure 1 and Figure 2 The dry-type reactor includes a high-voltage terminal 201, a grounding terminal 202, multiple enclosures 203, a star-shaped frame 204, and insulating support bars 205. The enclosures 203 are made of multiple strands of insulated wires wound together and then cured by vacuum casting of epoxy resin to form a rigid insulating cylindrical structure. The multiple enclosures 203 are arranged concentrically and coaxially from the inside to the outside. Each layer of enclosures 203 is parallel to each other and radially spaced to form a multi-layer annular hollow structure. Each layer of enclosures 203 has an independent upper surface, lower surface, and annular outer surface.

[0026] Among them, multiple high-strength insulating support strips 205 are evenly fixedly arranged circumferentially between adjacent inner and outer nested enclosures 203. The insulating support strips 205 are arranged vertically in the axial direction to radially support each enclosure 203 and fix the insulation spacing between layers, ensuring the concentricity and mechanical stability of the overall structure. Adjacent inner enclosures 203, outer enclosures 203, and circumferentially distributed insulating support strips 205 together form an air channel 206. The air channel 206 is the core heat dissipation channel of the reactor. The air channel 206 is hollow and unobstructed inside, allowing temperature probes to be inserted to achieve accurate acquisition of the internal temperature field of the reactor.

[0027] Specifically, a star-shaped frame 204 with a cross-shaped symmetrical structure is fixedly installed on the top of the multi-layer annular hollow structure. A high-voltage terminal 201 is set at the top of the multi-layer annular hollow structure for connecting to the high-voltage circuit of the system. A grounding terminal 202 is set at the bottom for equipment safety grounding. A current sensor 2021 can be sleeved on the outside of the grounding terminal 202. The current sensor 2021 is wirelessly connected to the remote device 20 and is used to collect the grounding current signal of the reactor in real time.

[0028] Continue to refer to Figure 1 In this embodiment, the external electrical parameter measurement component 11 includes an insulating pole 111, an insulating component 112, and multiple integrated electromagnetic field / potential sensors 113. The bottom end of the insulating pole 111 is slidably connected to the annular insulating guide rail 13. The insulating component 112 is slidably engaged with the outer wall of the insulating pole 111. The insulating component 112 can slide along the center line of the insulating pole 111 to adjust the height of the insulating component 112. Multiple integrated electromagnetic field / potential sensors 113 are arranged at intervals around the insulating component 112. All multiple integrated electromagnetic field / potential sensors 113 are wirelessly connected to the remote device 20.

[0029] It should be noted that the integrated electromagnetic field / potential sensor is a dedicated integrated detection device for external electrical parameters of dry reactors, and has the integrated synchronous acquisition function of electric field detection, magnetic field detection, and potential detection.

[0030] The center line of the insulating pole 111 is set parallel to the center line of the annular insulating guide rail 13.

[0031] Specifically, the bottom end of the insulating pole 111 is equipped with an insulating sliding base, and the annular insulating guide rail 13 is provided with a T-shaped groove. The insulating sliding base and the T-shaped groove of the annular insulating guide rail 13 are nested and slidingly fitted. The insulating sliding base has a built-in wireless drive execution component, which is wirelessly connected to the host computer 22 through the wireless receiver 21. The host computer 22 sends control commands and pulse positioning commands through wireless communication to drive the insulating sliding base to make precise annular sliding along the annular insulating guide rail 13. Sensorless precise alignment is achieved by relying on motor coding and counting. The insulating sliding base drives the insulating pole 111, the insulating component 112 and the external electrical parameter measurement component 11 to complete the circumferential position adjustment. After sliding into place, it automatically locks, realizing fully automatic alignment measurement of measuring points at different angles on the outer periphery of the dry reactor.

[0032] It should be noted that the wireless drive execution component is a well-known and mature modular structure, and its structure will not be described in detail here.

[0033] Furthermore, in this embodiment, the insulating component 112 includes a first horizontal insulating rod 1121, a second horizontal insulating rod 1122, and a vertical insulating rod 1123. The first horizontal insulating rod 1121 and the second horizontal insulating rod 1122 are slidably mounted on the insulating upright 111, and the vertical insulating rod 1123 is fixedly or slidably mounted on the insulating upright 111. The vertical insulating rod 1123 is located between the first horizontal insulating rod 1121 and the second horizontal insulating rod 1122. An integrated electromagnetic field / potential sensor 113 is provided on the first horizontal insulating rod 1121, the second horizontal insulating rod 1122, and the vertical insulating rod 1123.

[0034] Specifically, by adjusting the vertical height of the first horizontal insulating rod 1121 and / or the second horizontal insulating rod 1122, the electromagnetic field / potential integrated sensor 113 on the first horizontal insulating rod 1121 is aligned with the upper surface of the encapsulation 203 in the dry-type reactor 2 to be measured, the electromagnetic field / potential integrated sensor 113 on the second horizontal insulating rod is aligned with the lower surface of the encapsulation 203 in the dry-type reactor 2 to be measured, and the electromagnetic field / potential integrated sensor 113 on the vertical insulating rod 1123 is in contact with the outer surface of the encapsulation 203 in the dry-type reactor 2 to be measured, thereby simultaneously acquiring electrical parameters of multiple potentials on the upper surface, lower surface, and outer surface of the dry-type reactor 2 to be measured.

[0035] Specifically, the centerline of the first horizontal insulating rod 1121 is parallel to the centerline of the second horizontal insulating rod 1122, and the centerline of the vertical insulating rod 1123 is parallel to the centerline of the insulating pole 111 and perpendicular to the centerline of the first horizontal insulating rod 1121. Figure 1 Taking the orientation shown as an example, the integrated electromagnetic field / potential sensor 113 is located at the lower part of the first horizontal insulating rod 1121, the integrated electromagnetic field / potential sensor 113 is located at the upper part of the second horizontal insulating rod 1122, and the integrated electromagnetic field / potential sensor 113 is located on the left side of the vertical insulating rod 1123.

[0036] The number of electromagnetic field / potential integrated sensors 113 can be adjusted according to the actual situation of the dry reactor 2 to be measured.

[0037] In this embodiment, the outer wall of the insulating pole 111 is provided with a vertical guide groove along the axial direction. The first horizontal insulating pole 1121 and the second horizontal insulating pole 1122 are respectively fixedly connected to an insulating sliding seat at one end facing the insulating pole 111. The two sets of insulating sliding seats are respectively limited and slidably assembled on the outside of the insulating pole 111 and engaged with the vertical guide groove, so that the first horizontal insulating pole 1121 and the second horizontal insulating pole 1122 can slide independently vertically along the axial direction of the insulating pole 111. Each insulating sliding seat integrates an independent wireless insulating lifting drive component, which is wirelessly connected to the host computer 22 through the wireless receiver 21. The host computer 22 sends pulse lifting commands through wireless communication to drive the two sets of sliding seats to slide vertically and independently adjust the vertical height of the first horizontal insulating rod 1121 and the second horizontal insulating rod 1122 to adapt to the height of the measuring points on the upper and lower surfaces of the dry reactor enclosure 203 of different specifications. After adjustment, it automatically locks and positions itself to achieve accurate alignment measurement of the electrical parameter sensors on the upper and lower surfaces of the equipment.

[0038] It should be noted that the wireless insulated lifting drive assembly is a well-known and mature modular structure, and its structure will not be described in detail here.

[0039] When the vertical insulating rod 1123 is slidably installed on the insulating pole 111, an insulating slide is provided on the side of the vertical insulating rod 1123 facing the insulating pole 111. The slide is limited and slidably assembled on the outside of the insulating pole 111 and engaged with the vertical guide groove, so that the vertical insulating rod 1123 can slide vertically along the axial direction of the insulating pole 111. The insulating slide integrates an independent wireless insulating lifting control component. The wireless insulating lifting control component is wirelessly connected to the host computer 22 through the wireless receiver 21. The host computer 22 sends pulse control commands via wireless communication to drive the vertical insulating rod 1123 to slide vertically along the insulating pole 111 and be precisely positioned. The vertical height of the vertical insulating rod 1123 is independently adjusted to match the height range to be measured on the outer wall of the dry reactor enclosure 203. In conjunction with the first horizontal insulating rod 1121 and the second horizontal insulating rod 1122 on the upper and lower sides, the multi-area electrical parameter alignment measurement of the upper surface, lower surface and side enclosure 203 of the reactor is completed simultaneously. After adjustment, it automatically locks itself in place to ensure structural stability and accurate measurement points during the measurement process.

[0040] It should be noted that the wireless insulated lifting control component is a well-known and mature modular structure, and its structure will not be described in detail here.

[0041] Continue to refer to Figure 1In this embodiment, the internal non-electrical parameter measurement component 12 includes an insulating support rod 121, an insulating mounting bracket 122, and multiple temperature sensors 123. The bottom end of the insulating support rod 121 is slidably connected to the annular insulating guide rail 13. The insulating mounting bracket 122 is slidably mounted on the outer wall of the insulating support rod 121. The insulating mounting bracket 122 can slide along the center line of the insulating support rod 121 to adjust the height of the insulating mounting bracket 122. Multiple temperature sensors 123 are spaced apart on the insulating mounting bracket 122, and all multiple temperature sensors 123 are wirelessly connected to the remote device 20.

[0042] Specifically, the center line of the insulating support rod 121 is set parallel to the center line of the annular insulating guide rail 13.

[0043] It should be noted that the sliding connection structure between the insulating support rod 121 and the annular insulating guide rail 13 is basically the same as the sliding connection structure between the insulating upright rod 111 and the annular insulating guide rail 13. Therefore, the sliding connection structure between the insulating support rod 121 and the annular insulating guide rail 13 will not be described in detail here.

[0044] Further, in this embodiment, the insulating mounting bracket 122 includes a transverse insulating rod 1221 and a mounting rod 1222. The transverse insulating rod 1221 is slidably connected to the insulating support rod 121. The transverse insulating rod 1221 can slide along the center line of the insulating support rod 121. The top end of the mounting rod 1222 is slidably connected to the transverse insulating rod 1221. The mounting rod 1222 can slide along the center line of the transverse insulating rod 1221. The center line of the mounting rod 1222 is parallel to the center line of the insulating support rod 121. Multiple temperature sensors 123 are spaced apart on the mounting rod 1222. By vertically sliding the transverse insulating rod 1221 and horizontally adjusting the position of the mounting rod 1222, the temperature sensors 123 on the mounting rod 1222 can be inserted into the air passage 206 of the dry reactor 2 to be measured to measure the internal temperature distribution.

[0045] Specifically, the centerline of the transverse insulating rod 1221 is set perpendicular to the centerline of the insulating support rod 121, and the centerline of the mounting rod 1222 is set parallel to the centerline of the insulating support rod 121.

[0046] It should be noted that the number of temperature sensors 123 can be adjusted according to the actual size of the dry reactor 2 to be measured.

[0047] In this embodiment, the outer wall of the insulating support rod 121 is provided with a vertical guide groove along the axial direction. An insulating sliding seat is provided at one end of the transverse insulating rod 1221 facing the insulating support rod 121. The insulating sliding seat is assembled with the vertical guide groove through a limiting locking rib, so that the transverse insulating rod 1221 can slide vertically along the axial direction of the insulating support rod 121. An independent wireless insulating lifting drive module is integrated inside the insulating sliding seat. The wireless insulating lifting drive module is wirelessly connected to the host computer 22 through the wireless receiver 21. The host computer 22 sends a pulse lifting command through wireless communication to drive the insulating sliding seat to slide vertically along the insulating support rod 121, realizing fully automatic and precise adjustment of the vertical height of the transverse insulating rod 1221. The front-end temperature sensor 123 can be smoothly placed into any vertical depth position inside the dry reactor air passage 206. After adjustment, it automatically locks itself in place, adapting to the internal vertical full-range temperature measurement requirements of reactors of different specifications.

[0048] It should be noted that the wireless insulated lifting drive module is a well-known and mature modular structure, and its structure will not be described in detail here.

[0049] The transverse insulating rod 1221 has a transverse guide groove along its length. An insulating movable seat is located at the top of the mounting rod 1222. The insulating movable seat is fitted with the transverse guide groove via a limiting latch, allowing the mounting rod 1222 to slide horizontally along the transverse insulating rod 1221. An independent wireless insulating translation drive component is integrated inside the insulating movable seat. This component is wirelessly connected to the host computer 22 via a wireless receiver 21. The host computer 22 sends pulse translation commands via wireless communication, driving the insulating movable seat to slide horizontally along the transverse insulating rod 1221. This achieves fully automatic and precise adjustment of the transverse radial position of the mounting rod 1222. The insertion depth of the temperature sensor 123 can be adaptively adjusted according to the radial dimensions of the air passages 206 of the multi-layer encapsulation 203 of the dry-type reactor. After adjustment, it automatically locks itself in place, enabling precise measurement of the internal temperature field of different layers of the reactor.

[0050] It should be noted that the wireless insulated translation drive assembly is a well-known and mature modular structure, and its structure will not be described in detail here.

[0051] Continue to refer to Figure 1 In this embodiment, the remote device 20 includes a wireless receiver 21 and a host computer 22. The external electrical parameter measurement component 11 and the internal non-electrical parameter measurement component 12 are both wirelessly connected to the wireless receiver 21. The wireless receiver 21 is connected to the host computer 22. The host computer 22 is used to realize data reception, storage, analysis and remote control of the device.

[0052] Specifically, during use, the wireless receiver 21 is wired to the host computer 22. The wireless receiver 21 receives signals from the measuring device 10, the electromagnetic field / potential integrated sensor 113, and the temperature sensor 123. At the same time, the wireless receiver 21 receives wireless electromechanical operation signals from the measuring device 10. The host computer 22 performs all transmission operations on the measuring device 10. Meanwhile, the host computer 22 stores and analyzes the received data from the current sensor 2021, the electromagnetic field / potential integrated sensor 113, and the temperature sensor 123, and monitors the operation of the dry-type reactor in real time.

[0053] Second embodiment: Reference Figure 3 The second embodiment provides a measurement and testing method using the operating parameter measurement and testing device 1 of the dry reactor as described above, including the following steps: S1. Based on the dimensions of the dry-type reactor 2 to be measured, electromagnetic field / potential integrated sensors 113 are installed on the insulating component 112 of the external electrical parameter measurement component 11 at a preset interval, and temperature sensors 123 are installed on the insulating mounting frame 122 of the internal non-electrical parameter measurement component 12 at a predicted interval.

[0054] The preset spacing ranges from 0.2m to 0.4m, and the predicted spacing ranges from 0.2m to 0.4m.

[0055] Specifically, based on the specifications of the dry-type reactor 2 to be measured, determine the number and spacing of the integrated electromagnetic field / potential sensor 113 and temperature sensor 123, complete the wireless communication debugging of all sensors, measuring devices 10 and remote devices 20, and ensure stable signal transmission and normal equipment operation.

[0056] The dry-type reactor 2 to be measured is moved to the center position of the annular insulated guide rail 13. The high-voltage terminal 201 is used to connect to the high-voltage circuit of the system, the grounding terminal 202 is used for equipment safety grounding, and the current sensor 2021 can be installed on the outside of the grounding terminal 202.

[0057] S2. The external electrical parameter measurement component 11 and the internal non-electrical parameter measurement component 12 are remotely controlled by the host computer 22 in the remote device 20 to slide along the annular insulated rail 13 to the preset measurement position, and the height and lateral position calibrations are completed respectively, so that each sensor is aligned with the preset measurement point of the dry reactor 2 to be measured.

[0058] Specifically, S2, the external electrical parameter measurement component 11 and the internal non-electrical parameter measurement component 12 are remotely controlled by the host computer 22 in the remote device 20 to slide along the annular insulated guide rail 13 to the preset measurement position, and the height and lateral position calibrations are completed respectively, so that each sensor is aligned with the preset measurement point of the dry reactor 2 to be measured, including: S21. When the internal non-electrical parameter measurement component 12 is adjusted, the measuring device 10 is controlled by the host computer 22 to slide the transverse insulating rod 1221 upward along the center line of the insulating support rod 121. The transverse insulating rod 1221 drives the mounting rod 1222 and the temperature sensor 123 to move upward to a position higher than the top of the dry reactor 2 to be measured. The mounting rod 1222 is slid along the center line of the transverse insulating rod 1221 to the preset position to complete the transverse alignment. The transverse insulating rod 1221 is then slid downward along the center line of the insulating support rod 121 so that the temperature sensor 123 is placed inside the air passage 206 of the dry reactor 2 to be measured and fits against the outer wall of the encapsulation 203. S22. When the external electrical parameter measurement component 11 is adjusted, the host computer 22 controls the measuring device 10 to vertically slide the first horizontal insulating rod 1121 to the first predetermined height and the second horizontal insulating rod 1122 to the second predetermined height. This causes the integrated electromagnetic field / potential sensor 113 on the first horizontal insulating rod 1121 to be attached to the top surface of the enclosure 203 of the dry reactor 2 to be measured, and the integrated electromagnetic field / potential sensor 113 on the second horizontal insulating rod 1122 to be attached to the bottom surface of the enclosure 203 of the dry reactor 2 to be measured. At the same time, the integrated electromagnetic field / potential sensor 113 on the vertical insulating rod 1123 is attached to the outer surface of the enclosure 203 of the dry reactor 2 to be measured, so as to complete the alignment of the electrical parameter measurement points in multiple areas on the top, outer, and bottom surfaces of the dry reactor 2 to be measured.

[0059] S3. Apply rated voltage and rated current to the dry-type reactor 2 to be measured, and simulate a complex operating environment. All sensors synchronously and in real time collect multi-dimensional operating parameters of the dry-type reactor 2 to be measured, and wirelessly transmit them to the remote device 20. The host computer 22 completes the reception, storage and analysis of multi-dimensional operating parameter data, and realizes the measurement test of the operating status of the dry-type reactor 2 to be measured.

[0060] Specifically, rated voltage and rated current are applied to the dry-type reactor 2 to be measured, and complex operating conditions such as pollution and rainwater are simulated. The current, electric field, magnetic field, potential, and internal temperature parameters of the dry-type reactor 2 under test are collected in real time synchronously through the current sensor 2021, the electromagnetic field / potential integrated sensor 113, and the temperature sensor 123. The wireless receiving device 21 receives the parameter data collected by all sensors in real time and transmits it to the host computer 22. The host computer 22 completes real-time data storage and multi-dimensional analysis, sorts out the parameter change patterns under different operating conditions and at different points, identifies the key points and weak points of equipment operation, and completes the assessment of the operating status of the dry-type reactor.

[0061] For ease of description, the following description will be based on a dry-type reactor 2 to be measured, which has four enclosures 203, a star-shaped frame 204 with a cross-shaped structure, and an outer enclosure 203 with a height of 1m.

[0062] First, the number of integrated electromagnetic field / potential sensors 113 and temperature sensors 123 is determined. Four integrated electromagnetic field / potential sensors 113 are mounted on each of the first horizontal insulating rod 1121 and the second horizontal insulating rod 1122, and five integrated electromagnetic field / potential sensors 113 are mounted on the vertical insulating rod 1123, with a 0.25m interval between any two adjacent sensors. The integrated electromagnetic field / potential sensors 113 on the first horizontal insulating rod 1121 correspond to the upper surface of the enclosure 203, the integrated electromagnetic field / potential sensors 113 on the second horizontal insulating rod 1122 correspond to the lower surface of the enclosure 203, and the integrated electromagnetic field / potential sensors 113 on the vertical insulating rod 1123 correspond to the outermost surface of the enclosure 203. Additionally, five temperature sensors 123 are mounted on the mounting rod 1222, with a 0.25m interval between any two adjacent temperature sensors 123.

[0063] After completing all sensor communication debugging and electromechanical operation communication of the measuring equipment 10, the dry-type reactor body is moved to the middle of the annular insulated rail 13, with the high-voltage terminal 201 and grounding terminal 202 avoiding contact with the measuring equipment 10. The position of the external electrical parameter measuring component 11 is controlled by the host computer 22 so that the integrated electromagnetic field / potential sensor 113 reaches the measuring position of the dry-type reactor, located on one side of the 90° star frame 204. The heights of the first horizontal insulating rod 1121 and the second horizontal insulating rod 1122 are adjusted according to the height of the dry-type reactor enclosure 203 to ensure that each integrated electromagnetic field / potential sensor 113 is in close contact with the surface to be measured, thus completing the electric field, magnetic field, and potential measurements. Measurement point calibration: The position of the internal non-electrical parameter measurement component 12 is controlled by the host computer 22. The horizontal insulating rod 1221 is slid upward along the center line of the insulating support rod 121. The horizontal insulating rod 1221 drives the mounting rod 1222 and the temperature sensor 123 to move upward to a position higher than the top of the dry reactor 2 to be measured. The mounting rod 1222 is slid to the preset position along the center line of the horizontal insulating rod 1221 to complete the horizontal alignment. The horizontal insulating rod 1221 is then slid downward along the center line of the insulating support rod 121 so that the temperature sensor 123 is placed inside the air passage 206 of the dry reactor 2 to be measured, closely adhering to the outer wall of the inner layer of the air passage 206, ensuring accurate and effective internal temperature measurement data. After all sensors are set up, rated voltage and rated current are applied to the dry-type reactor 2 to be measured, and complex operating conditions such as pollution and rainwater are simulated. The parameter data of the dry-type reactor 2 under test are collected synchronously and in real time through the current sensor 2021, the electromagnetic field / potential integrated sensor 113, and the temperature sensor 123. The host computer 22 classifies, stores, compares and analyzes the current, electromagnetic, and temperature data at different times and locations, sorts out the parameter fluctuation patterns of each area of ​​the dry-type reactor under complex operating conditions, identifies weak areas such as abnormal temperature and uneven electromagnetic distribution, completes a comprehensive evaluation of the equipment's operating status, and records effective test data to provide a basis for equipment optimization design.

[0064] The beneficial technical effects of the dry-type reactor operation parameter measurement test device 1 and measurement test method provided in this application are as follows: 1. By setting up a wireless communication connection between the measurement device 10 and the remote device 20, the complexity of laying a large number of cables is avoided, and the safety of high-voltage testing is improved; 2. By real-time monitoring of multiple parameters during the operation of the dry-type reactor, the multiple parameters are stored and analyzed simultaneously to understand the operation of the dry-type reactor, optimize the design of the dry-type reactor, and ensure the safe and stable operation of the equipment; 3. Through the coordinated cooperation of the external electrical parameter measurement component 11 and the internal non-electrical parameter measurement component 12, the multi-dimensional core parameters of electric field, magnetic field, potential, and internal temperature during the operation of the dry-type reactor can be collected simultaneously. At the same time, through the sliding, lifting, and horizontally adjustable sensor architecture, the full-point measurement of the upper and lower surfaces of the equipment, the side enclosure 203, and the air passage 206 can be realized, which solves the problem of single measurement dimension and incomplete point coverage in the existing technology, and can accurately obtain the change law of operating parameters under complex working conditions of the equipment.
