Description

Technical Field

[0001] This invention relates to the field of small switchgear, specifically a portable power switchgear discharge detection terminal. Background Technology

[0002] Discharge detection of switchgear is a key means to ensure the safe operation of power equipment. Its core is to detect partial discharge phenomena inside the switchgear caused by insulation defects, electric field distortion, etc., and to provide early warning of equipment failure risks. The current mainstream detection method is ultrasonic detection, which uses ultrasonic sensors attached to the switchgear shell to capture signals and determine the location and intensity of the discharge. Existing ultrasonic testing devices are mostly handheld testing terminals, which can directly acquire test data during the testing process and directly upload and store the test values ​​via the network through a wireless transmission module. Portable power switch cabinets, also known as small power switch cabinets, are designed for easy relocation and use. Due to the special nature of their use scenarios, they often do not have strict testing cycles during use, which poses certain safety hazards during discharge operations and makes them inconvenient to use.

[0017] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figures 1-8 The present invention provides the following technical solutions: A portable power switchgear discharge detection terminal includes a switchgear housing 1. A power connection control backplate 2 is provided on one side of the switchgear housing 1. A movable switching assembly, which can move up and down, is movably mounted on the power connection control backplate 2. The movable switching assembly includes a control rod 5, a U-shaped support frame 6, and a rectangular frame 7. A movable slot 3 is formed at the upper end of the power connection control backplate 2, and a storage slot 4 is formed at the lower end of the power connection control backplate 2 near the switchgear housing 1. A guide slot 23 is formed between the movable slot 3 and the storage slot 4. The control rod 5 is movably inserted through the guide slot 23, with both ends of the control rod 5 inserted into the movable slot 3 and the storage slot 4, respectively. The U-shaped support frame 6 and the rectangular frame 7 are respectively located on the movable slot 5. Inside slots 3 and 4, U-shaped support frame 6 and rectangular frame 7 are respectively connected to one end of control rod 5 in slot 3 and 4. The lower end of rectangular frame 7 is provided with two casters 8. When control rod 5 moves up and down in guide slot 23, U-shaped support frame 6 and rectangular frame 7 can move up and down. When rectangular frame 7 moves up to its maximum extent in 4, casters 8 retract into 4. Conversely, when U-shaped support frame 6 descends to its maximum extent, casters 8 extend out of 4. Portable movement of switch cabinet housing 1 can be achieved through casters 8. During normal operation, casters 8 retract into 4 to ensure stable placement of switch cabinet housing 1.

[0019] Please refer to Figure 3-6 A flip-mounted mounting plate 9 is rotatably connected to the U-shaped support frame 6 via a pin. A detection terminal instrument 11 is mounted on the flip-mounted mounting plate 9. One side of the detection terminal instrument 11 is set to make detectable contact with the switch cabinet housing 1. A recessed mounting groove 10 is opened on one side of the flip-mounted mounting plate 9. The detection terminal instrument 11 is fixed in the recessed mounting groove 10 by bolts. A detection groove 26 is opened at the upper end of the switch cabinet housing 1. When the moving wheel 8 is retracted into the storage groove 4, the flip-mounted mounting plate 9 is horizontally inserted into the detection groove 26. The detection terminal instrument 11 and the flip-mounted mounting plate 9 are detachably connected by bolts, which is convenient for future replacement and repositioning. The detection principle of the detection terminal instrument 11 is the same as the common handheld magnetic attraction detection principle in the prior art. By integrating the flip-mounted mounting plate 9 with the switch cabinet housing 1 into a modular setting, real-time discharge detection can be realized.

[0020] Both sides of the flip-mount plate 9 are provided with transceiver slots 13, and both sides of the detection terminal instrument 11 are provided with signal transceiver rods 14. The two signal transceiver rods 14 are respectively inserted into the two transceiver slots 13. The setting of the signal transceiver rods 14 can more stably upload the detection values ​​to the network after the discharge detection data of the detection terminal instrument 11 is read. In addition, if the value is abnormal, it can be reminded through the network. The detection terminal instrument 11 can also perform on-site detection value reading, thus fulfilling the basic function of the detection terminal.

[0021] Please refer to Figure 4-5 A contact detection component is installed to achieve stable contact during testing. The contact detection component is located on one side of the testing terminal instrument 11 and includes a spring box 15 and a magnetic detection head 16. One side of the magnetic detection head 16 contacts the switch cabinet housing 1. A through hole is provided at the lower end of the recessed mounting groove 10. The spring box 15 is located on the side of the testing terminal instrument 11 near the through hole, and one side of the spring box 15 is inserted into the through hole. A spring groove is provided at the lower end of the spring box 15, and the magnetic detection head 16 is movably placed in the spring groove. The magnetic detection head 16 is connected to the testing terminal instrument 11 via a wire. An anti-detachment plate 17 is horizontally installed on the side of the magnetic detection head 16 located in the spring groove. A downward pressure spring 18 is provided on one side of the upper end of 17 and inside the spring groove. One side of the magnetic attraction detection head 16 extends out of the spring box 15 and passes through the through groove to make magnetic contact with the switch cabinet housing 1. Before the magnetic attraction detection head 16 contacts the switch cabinet housing 1, the magnetic attraction detection head 16 applies an outward elastic force through the downward pressure spring 18. When the magnetic attraction detection head 16 contacts the switch cabinet housing 1, in addition to the magnetic attraction connection of the magnetic attraction detection head 16 itself, there is also an elastic auxiliary pressing to ensure that the magnetic attraction detection head 16 can make stable contact with the switch cabinet housing 1 to achieve ultrasonic detection. At the same time, the magnetic attraction detection head 16 can avoid external environmental interference during detection by being covered by the flip mounting plate 9, thereby improving the accuracy of the detection value.

[0022] Please refer to Figure 2-3 and Figure 7-8A limiting fastening assembly is set to limit the position of the flip-mount plate 9 when it is not in the detection state, while keeping the moving wheel 8 out of the storage slot 4. The limiting fastening assembly includes two constraint slots 19 and two constraint slots 22. The two constraint slots 19 and two constraint slots 22 are respectively set on the U-shaped support frame 6 and the power control back panel 2. When the detection terminal instrument 11 is covered for protection, the constraint slots 19 and constraint slots 22 correspond to each other. The two constraint slots 19 are respectively opened on the side of the U-shaped support frame 6 away from the pin shaft. Two hanging rods 21 are symmetrically provided on the side of the flip-mount plate 9 away from the pin shaft. When the flip-mount plate 9 is vertically inserted into the movable slot 3, the two hanging rods 21 are respectively inserted into the two constraint slots 19. When the flip-mount plate 9 is rotated by the pin shaft, the side of the flip-mount plate 9 with the detection terminal instrument 11 is close to the switch cabinet housing 1, realizing the safety protection of the detection terminal instrument 11 when it is not in the detection use.

[0023] Elastic constraint blocks 20 are provided on both sides of the constraint groove 19 near the hanging rod 21. When the U-shaped support frame 6 is at the bottom of the movable groove 3, the moving wheel 8 extends out of the storage groove 4. One side of each of the two hanging rods 21 is inserted into the two constraint slots 22. A combination window 25 is provided through one side of the storage groove 4. A guide plate 24 is horizontally provided on one side of the combination window 25 of the switch cabinet housing 1. One side of the guide plate 24 is inserted into the combination window 25, and the two sides of the rectangular frame 7 are in contact with the two sides of the guide plate 24. When the constraint groove 19 and the constraint slot 22 are not aligned, the hanging rod 21 cannot be inserted into the constraint groove 19 due to its length. When they are aligned, the hanging rod 21 can be inserted into both the constraint groove 19 and the constraint slot 22 at the same time. The elastic constraint block 20 is an elastic rubber block. After the hanging rod 21 is inserted into the constraint groove 19, the elastic constraint block 20 can remove the hanging rod 21 without human intervention. At this time, the moving wheel 8 extends out of the storage groove 4, and the switch cabinet housing 1 can be moved conveniently by the moving wheel 8.

[0024] Telescopic slots are provided on both sides of the upper end of the power control back panel 2. A U-shaped handrail 12 is provided on one side of the power control back panel 2. The two sides of the switch cabinet housing 1 are respectively movably inserted into the two telescopic slots through constraint blocks. The U-shaped handrail 12 is used to pull and drag the switch cabinet housing 1.
