[0033] like Figures 1 to 5 As shown, the discharge detection device includes a housing 100, a housing cover 200, a first motor 300 and a detection assembly.
[0034] The housing cover plate 200 is movably arranged on the housing 100. The first motor 300 is connected to the housing 100 through the housing cover plate 200, and the first motor 300 is used to adjust the detection angle so that the housing 100 is parallel to the cabinet surface of the power distribution cabinet; the detection component includes a detection module 400 and a moving component 500, and the detection module 400 is movably arranged on the moving component 500. The detection module 400 has an extended state and a retracted state. In the extended state, the moving component 500 drives the detection module 400 to extend out of the housing 100, and the detection module 400 is used to perform partial discharge detection on the power distribution cabinet.
[0035] The first motor 300 adjusts the detection angle so that the housing 100 is parallel to the cabinet surface of the distribution cabinet. This ensures that the detection module 400 can accurately detect the distribution cabinet, thereby improving the accuracy and reliability of the detection. The detection component includes a detection module 400 and a mobile component 500, and the detection module 400 is movably arranged on the mobile component 500. This design enables the detection module 400 to flexibly extend out of the housing 100 for detection, and retract into the housing 100 after the detection is completed, thereby protecting the detection equipment and extending its service life. The detection module 400 is specifically used for partial discharge detection, which can promptly detect possible partial discharge problems in the distribution cabinet, prevent the occurrence of faults, and ensure the safe and stable operation of the power system.
[0036] In some embodiments, the detection module 400 includes a sensor 410 and a sensor housing 420. The sensor housing 420 is mounted on the sensor 410. The sensor 410 is used to detect partial discharge of the distribution cabinet. The first motor 300 is used to adjust the sensor housing 420 to be parallel to the cabinet surface of the distribution cabinet.
[0037] The installation of the sensor housing 420 can effectively protect the sensor 410 from the influence of the external environment, ensure the accuracy and stability of the sensor 410, and extend its service life. The first motor 300 ensures that the sensor 410 performs partial discharge detection on the distribution cabinet at the optimal angle by adjusting the sensor housing 420 to be parallel to the cabinet surface of the distribution cabinet. It helps to improve the accuracy and reliability of the detection and ensure that there will be no missed detection or misjudgment. The sensor 410 is specifically used to detect partial discharge in the distribution cabinet. The precise adjustment of its position and angle can ensure that the sensor 410 can accurately capture the discharge signal, thereby promptly discovering possible hidden faults and ensuring the safe and stable operation of the power system.
[0038] In some embodiments, the detection module 400 also includes a module sleeve 430 and a second motor 440. The sensor 410 and the sensor housing 420 are arranged at one end of the sleeve module, and the second motor 440 is arranged at the other end of the sleeve module. The second motor 440 drives the module sleeve 430 to move to switch the state of the detection module 400.
[0039] The second motor 440 drives the module sleeve 430 to move, which can realize the state switching of the detection module 400, so that the extended state and the retracted state of the module can be flexibly switched during detection. The setting of the module sleeve 430 can effectively protect the sensor 410 and the sensor housing 420 from the influence of the external environment, extend their service life, and improve the accuracy and reliability of detection. The design of the module sleeve 430 can ensure that the sensor 410 is detected in the best position. With the state switching function of the second motor 440, it can realize the accurate detection of partial discharge of the distribution cabinet, find problems in time, and ensure the safe operation of the power system.
[0040] In some embodiments, the detection module 400 also includes an in-place detection module 450 and a guide column 460. The in-place detection module 450 is fixedly arranged inside the module sleeve 430, and the guide column 460 is arranged at one end of the sensor 410. The second motor 440 drives the detection module 400 to extend out of the outer shell 100, the guide column 460 contacts the in-place detection module 450, the second motor 440 pauses, and the sensor 410 performs partial discharge detection on the distribution cabinet.
[0041] By utilizing the design of the in-place detection module 450 and the guide column 460, it is possible to automatically detect whether the detection module 400 is completely extended from the housing 100. When the guide column 460 contacts the in-place detection module 450, it indicates that the detection module 400 has been completely extended from the housing 100. At this time, the second motor 440 is paused, and the sensor 410 starts to perform partial discharge detection on the distribution cabinet. The intervention of the operator is reduced, and the automation and reliability of the detection are improved. Through automatic in-place detection, it can be ensured that the detection module 400 performs partial discharge detection in the correct position, avoiding detection errors caused by inaccurate position. It helps to improve the accuracy and reliability of detection, timely discover possible problems in the distribution cabinet, and ensure the safe operation of the power system.
[0042] In some embodiments, the detection module 400 also includes a guide column fixing seat 461 and a spring 462. The guide column fixing seat 461 is used to fix the guide column 460, and the spring 462 is mounted on the guide column. When the detection module 400 is extended, the sensor housing 420 and the sensor 410 drive the guide column 460 to compress the spring 462, so that the guide column 460 contacts the in-place detection module 450, and the sensor 410 performs partial discharge detection on the distribution cabinet.
[0043] The design of the guide post fixing seat 461 and the spring 462 can provide additional stable support to ensure that the guide post 460 remains stable when in contact with the in-place detection module 450 in the extended state. The sleeve of the spring 462 enables the sensor housing 420 and the sensor 410 to flexibly drive the guide post 460 to compress the spring 462 when the detection module 400 is extended, so as to adapt to the pressure changes in different situations. This helps to ensure that the guide post 460 can effectively contact with the in-place detection module 450, thereby improving the accuracy and reliability of the detection.
[0044] In some embodiments, the detection module 400 further includes a gear 470 , which is disposed at one end of the module sleeve 430 close to the second motor 440 . The gear 470 is used to cooperate with the moving assembly 500 to switch the state of the detection module 400 .
[0045] The setting of the gear 470 can cooperate with the moving assembly 500 to realize the switching of the state of the detection module 400. Through the transmission action of the gear 470, the movement of the module sleeve 430 can be accurately controlled, thereby realizing the switching of the extended and retracted states of the detection module 400. By realizing state switching through the transmission of the gear 470, the number and complexity of mechanical parts can be reduced, the structure of the detection device can be simplified, and the maintenance cost and failure rate can be reduced. The gear 470 transmission has high wear resistance and durability, can withstand large forces and repeated use, can ensure the stability and reliability of the state switching of the detection module 400, and extend the service life of the device.
[0046] In some embodiments, the moving assembly 500 includes a detection module mounting base 510 and a rack 520, the rack 520 is fixedly disposed on the detection module mounting base 510, the detection module 400 is movably connected to the detection module mounting base 510, and the second motor 440 drives the gear 470 to engage with the rack 520, so that the detection module 400 switches to different detection states.
[0047] The design of the moving assembly 500 enables the second motor 440 to accurately control the position and state of the detection module 400 by driving the meshing movement of the gear 470 and the rack 520. It can ensure that the detection module 400 is accurately positioned when switching different detection states, thereby improving the accuracy and reliability of detection. The rack 520 is fixedly arranged on the mounting seat of the detection module 400, ensuring the firm connection between the rack 520 and the detection module 400, thereby improving the stability and reliability of the moving assembly 500.
[0048] In some embodiments, the moving assembly 500 further includes a front limit detection module 530, which is disposed at one end of the rack 520. When the detection module 400 is extended, the second motor 440 drives the gear 470 to move to trigger the front limit detection module 530, the second motor 440 stops moving, and the sensor 410 performs partial discharge detection on the power distribution cabinet. The moving assembly 500 further includes a rear limit detection module 540, which is disposed at one end of the rack 520 away from the front limit detection module 530.
[0049] The setting of the front limit detection module 530 and the rear limit detection module 540 allows the second motor 440 to accurately control the position of the detection module 400 during the movement, and stop the movement when the preset position is reached. The front limit detection module 530 can ensure that the detection module 400 will not exceed the set maximum position in the extended state, and the rear limit detection module 540 ensures that it will not move backward excessively in the retracted state, thereby effectively protecting the equipment from damage or collision. Through the setting of the limit detection module, it is possible to avoid the detection module 400 from exceeding the safety range during operation, thereby reducing the risk of accidents. Once the detection module 400 reaches the preset front limit or rear limit, the second motor 440 will stop moving to ensure the safety of the equipment and the operator. The setting of the front limit detection module 530 and the rear limit detection module 540 simplifies the operation process of the detection module 400. The operator does not need to manually monitor the position of the detection module 400, but relies on the automatic limit detection system to control and protect the detection process, which improves the convenience and efficiency of operation.
[0050] In some embodiments, the moving assembly 500 further includes a guide rail 550 , which is disposed on a mounting base of the detection module 400 . The second motor 440 drives the gear 470 and the rack 520 to engage and move, and the detection module 400 performs linear motion along the guide rail 550 .
[0051] The setting of the guide rail 550 can ensure that the detection module 400 moves along the linear track, making the movement process more stable. It helps to reduce the swing and jitter during movement, and improves the accuracy and reliability of detection. The guide rail 550 can provide a good guiding effect, ensuring that the detection module 400 moves in a straight line along a predetermined path, thereby achieving precise control of the movement.
