[0002] Reactors are indispensable components in power systems, widely used for short-circuit current limiting, power frequency overvoltage suppression, and phase-shift filtering. The stability and reliability of their performance are directly related to the overall operational safety and efficiency of power systems. Over extended operation, reactors are prone to interturn insulation failures due to factors such as manufacturing processes, material aging, and overvoltage. If these failures are not promptly detected and addressed, they can lead to reactor burnout and even major operational accidents, resulting in significant economic losses. Given the harmful effects of reactor insulation failures and the limitations of traditional detection methods, a detection device is needed that can comprehensively, accurately, and in real time detect reactor insulation failures.

DETAILED DESCRIPTION

[0015] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be understood as limiting the present invention.

[0016] like Figure 1 and Figure 2As shown, the reactor insulation detection device specifically includes a detection platform 1, a detection mechanism and a fixing component. The fixing component is arranged on the detection platform 1, and the fixing component includes a reactor limit platform 2, a clamping plate 3, a hydraulic cylinder 4 and a fixing seat 5. The reactor limit platform 2 is arranged on the detection platform 1, and the fixing seat 5 is arranged on one side of the reactor limit platform 2. The hydraulic cylinder 4 is arranged on the fixing seat 5, and one end is connected to the clamping plate 3. An adjustment mechanism is arranged at the connection between the clamping plate 3 and the hydraulic cylinder 4. The detection platform 1 serves as the basic platform of the entire detection device, provides a stable working environment, ensures the accuracy and safety of the detection process, supports and fixes all detection equipment and components, and is easy to operate and maintain; the reactor limit platform 2 accurately positions the reactor to prevent it from moving or tilting during the detection process, thereby ensuring the stability and safety of the reactor during the detection process; the clamping plate 3 is driven by the hydraulic cylinder to achieve a fast and stable clamping function, adapt to reactors of different sizes, firmly fix the reactor, and prevent it from loosening or detachment, the power of the hydraulic cylinder 4 is used to realize the precise control of the splint 3, drive the splint 3 to open and close, and the fixed seat 5 firmly supports the hydraulic cylinder 4 to ensure its stability during operation; the detection mechanism includes a high-voltage power supply 6, an insulation resistance tester 7 and a voltage and current sensor 8. The high-voltage power supply 6 is installed on one side of the detection platform 1, and the high-voltage power supply 6 is connected to the insulation resistance tester 7 through a high-voltage cable 9 to provide the required high-voltage power for the insulation resistance test 7. The insulation resistance tester 7 is connected to the inductor through a test cable 10, and the voltage and current sensor 8 is installed on the other side of the inductor limit platform 2. During implementation, the high-voltage power supply 6 on the detection mechanism provides a stable high-voltage output to meet the needs of the insulation resistance test and provide the required high-voltage power for the insulation resistance tester 7 to ensure the accuracy of the test. The insulation resistance tester 7 accurately measures the insulation resistance value of the reactor and judges its insulation performance. The voltage and current sensor 8 monitors the voltage and current changes in the test process in real time to ensure the safety of the test and provide a basis for data analysis.

[0017] like Figure 2As shown, based on the above method, the adjustment mechanism includes an adjustment screw 11, a guide block 12, and an elastic element 13. The guide block 12 is sleeved on one end of the hydraulic cylinder 4. The adjustment screw 11 is connected to the guide block 12. The elastic element 13 is arranged between the guide block 12 and the clamping plate 3. During implementation, the adjustment screw 11 can be rotated to achieve precise adjustment of the distance between the clamping plate 3 and the reactor. Rotating the adjustment screw 11 can accurately control the opening and closing degree of the clamping plate 3, thereby achieving precise control of the clamping force of the reactor. The guide block 12 is sleeved on one end of the hydraulic cylinder 4, providing a stable guide path for the adjustment screw 11. This allows the adjustment screw to maintain linear motion during rotation, avoiding uneven clamping force caused by offset. The elastic element 13 plays a buffering and protective role. During the process of clamping the reactor, the elastic element 13 can absorb and disperse the impact force generated by the hydraulic cylinder 4, preventing damage or deformation of the reactor surface caused by direct contact.

[0018] like Figure 2 As shown, on the basis of the above method, a breaker 14 is further provided on one side of the voltage and current sensor 8, the breaker 14 is connected to the drive motor 15, and the drive motor 15 is connected to drive the reactor away from the reactor limit platform 2. During implementation, the breaker 14 and the drive motor 15 quickly cut off the power supply in an emergency, and the reactor is moved away by the drive motor 15 to improve safety. The breaker 14 automatically cuts off the power supply when an abnormality is detected, and the drive motor 15 is used to move the reactor away from the detection position to avoid potential danger.

[0019] like Figure 2 As shown, based on the above method, a reactor containing shell 16 is further provided on the reactor limit platform 2. During implementation, the reactor containing shell 16 provides additional protection for the reactor to prevent external interference and damage. It is provided on the reactor limit platform 2 to provide a closed detection environment for the reactor.

[0020] like Figure 1 As shown, on the basis of the above method, an insulating cover 17 is further provided on the outside of the test bench 1. During implementation, the insulating cover 17 improves the electrical safety during the test process, prevents high-voltage electric shock, covers the outside of the test bench 1, isolates the high-voltage electric field, and protects the safety of the operator.

[0021] like Figure 3 As shown, based on the above method, the high-voltage power supply 6, insulation resistance tester 7 and voltage and current sensor 8 are further connected to the data control panel 18. The data control panel 18 is set on the side of the test platform 1. During implementation, the data control panel 18 centrally controls and manages various parameters and data during the test process, realizing real-time monitoring and recording of data. At the same time, an operation interface is provided to facilitate the user to set parameters and view results.

[0022] During the specific operation of the novel reactor insulation detection device, the reactor is placed on the reactor limit platform 2 to ensure that the reactor is accurately positioned to prevent movement or tilting during the detection process. Check and confirm that all equipment and components are correctly connected and in good working condition. Start the hydraulic cylinder 4, and use the driving force of the hydraulic cylinder 4 to move the clamp 3 toward the reactor. Before the clamp 3 contacts the reactor, adjust the opening and closing degree of the clamp 3 through the adjustment mechanism to ensure that the clamping force can be accurately controlled to avoid being too tight or too loose. The elastic element 13 acts as a buffer during the clamping process to protect the surface of the reactor from damage. Turn on the high-voltage power supply 6 to provide a stable high-voltage output for the insulation resistance tester 7. The insulation resistance tester 7 is connected to the reactor through the test cable 10 and starts to measure the insulation resistance value of the reactor. At the same time, the voltage and current sensor 8 monitors the voltage and current changes during the test in real time to ensure the safety of the test and provide a basis for data analysis. Various test data are monitored and recorded in real time through the data control panel 18. The data control panel 18 provides an operation interface for users to easily set parameters and view results. The insulation performance of the reactor is analyzed based on the measurement results of the insulation resistance tester 7 and the data of the voltage and current sensor 8. If an abnormality occurs during the detection process, the breaker 14 will quickly cut off the power supply to ensure safety. At the same time, the drive motor 15 can be started to move the reactor away from the detection position to avoid potential dangers. After the detection is completed, turn off the high-voltage power supply 6 and other related equipment. Through the reverse drive of the hydraulic cylinder 4, the splint 3 releases the reactor and removes the reactor from the reactor limit platform 2. Clean the test platform 1 and the surrounding environment and prepare for the next test. The entire process uses highly automated equipment and precise control systems to achieve efficient and accurate detection of the insulation performance of the reactor while ensuring the safety of the operator.
