Description

Technical Field

[0001] This invention relates to the field of electricity meter testing technology, and more specifically, to a testing connection device for testing electricity meters. Background Technology

[0002] In modern power systems, electricity meters are crucial metering devices whose accuracy directly impacts electricity measurement and management. They are used to measure and record electricity consumption. Typically installed in the power systems of homes, commercial buildings, or industrial facilities, they measure and record the total amount of electricity consumed by users within a certain timeframe. Because electricity meters are used long-term, on-site calibration is necessary to ensure the accuracy of the data.

[0003] In this technology, workers wearing insulated gloves connect the calibrator to the phase terminals of the electricity meter. The alligator clips of the calibrator are directly clamped to the phase terminals of the electricity meter, ensuring that the electricity meter can be calibrated on-site using the calibrator.

[0004] However, in related technologies, the phase terminals of the electricity meter are spaced close together. When workers wear insulated gloves and clamp the alligator clips onto the phase terminals of the electricity meter, it is easy for two adjacent alligator clips to accidentally touch other terminals, resulting in a phase-to-phase short circuit and affecting the accuracy of the verification.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. Based on 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.

[0029] like Figures 1 to 3As shown, this embodiment of the invention provides a testing connection device for testing electricity meters. The testing connection device includes a frame 10, a fixing component 20, an adjusting component 30, and a testing element 40. The fixing component 20 includes two movable components 21, both movably mounted on the frame 10 along its length. Each movable component 21 has an electricity meter connection portion. The adjusting component 30 includes two adjusting components 31, both movably mounted on the frame 10 along its length and spaced apart along its width. Each adjusting component 31 has a calibrator connection portion 311 and a testing element 40. The testing element 40 can abut against the phase terminal of the electricity meter and can be connected to the calibrator signal via the adjusting components 31.

[0030] The testing connection device for electricity meter testing provided in this embodiment includes a frame 10, a fixing component 20, an adjusting component 30, and a testing component 40. Two movable components 21 are movably mounted on the frame 10 along its length. Each movable component 21 has an electricity meter connection portion. This allows the testing connection device to be installed on the electricity meter via the electricity meter connection portions on the movable components 21 when needed. Furthermore, the testing connection device can be installed on electricity meters of different sizes and models. On the electricity meter, by adjusting the positions of the two moving parts 21 on the frame 10, the electricity meter connection parts of both moving parts 21 can be connected to the electricity meter. Different sizes and models of electricity meters can be matched by adjusting the spacing between the two moving parts 21 or their positions on the frame 10. The two adjusting parts 31 of the adjusting assembly 30 are movably arranged on the frame 10 along its length and spaced apart along its width. The two moving parts 21 are positioned on the two adjusting parts 31. Between the two adjusting members 31, each is provided with a calibrator connection part 311, and each adjusting member 31 is provided with a detection element 40. After the moving member 21 moves to the appropriate position, the frame 10 is fixed on the energy meter. The adjusting member 31 is moved along the length direction of the frame 10, and the detection element 40 on the adjusting member 31 is brought into contact with the phase terminals of the energy meter. Specifically, the detection element 40 of one adjusting member 31 is brought into contact with the first row of phase terminals of the energy meter, and the detection element 40 of the other adjusting member 31 is brought into contact with the second row of phase terminals of the energy meter. The terminals are connected to each other, and the calibrator can be connected to the calibrator connection part 311 on the regulating member 31. This facilitates the use of the calibrator to calibrate and test the energy meter. Directly connecting the calibrator to the calibrator connection part 311 on the regulating member 31 avoids the problem of workers wearing insulating gloves clamping the alligator clips on the phase terminals of the energy meter, which could easily cause adjacent alligator clips to touch and cause a short circuit between the first phase. This ensures the accuracy of the calibrator in calibrating the energy meter and improves the structural reliability and practicality of the testing connection device.

[0031] like Figure 1As shown, the adjusting member 31 includes an adjusting unit 312, which includes a mounting plate 3121 and a moving block 3122. The mounting plate 3121 extends along the width direction of the frame 10 and is movably disposed on the frame 10 along the length direction of the frame 10. The moving block 3122 is movably disposed on the mounting plate 3121 along the width direction of the frame 10. The first end of the detection member 40 is disposed on the moving block 3122, and the second end of the detection member 40 abuts against the phase terminal. With the above structure, the adjustment unit 312 includes a mounting plate 3121 and a moving block 3122. The mounting plate 3121 can extend along the width direction of the frame 10 and can be movably mounted on the frame 10 along the length direction of the frame 10, so that the adjustment unit 312 can move on the frame 10 under the action of the mounting plate 3121, thereby adjusting the position of the adjustment unit 312 on the frame 10, and ensuring that the detection element 40 on the adjustment unit 312 can abut against the limit terminal of the energy meter. Furthermore, in order to facilitate the contact between the detection element 40 on the adjustment unit 312 and the phase terminal of the energy meter, the moving block 3122 can move along the width direction of the frame 10 on the mounting plate 3121, and the detection element 40 is set on the moving block 3122. This ensures that the position of the detection element 40 can be adjusted to ensure that the detection element 40 can contact the phase terminal of the energy meter, thereby matching the phase terminals of energy meters of different models and sizes, and ensuring that the movement of the mounting plate 3121 relative to the frame 10 is simple and reliable.

[0032] like Figure 1 As shown, the side wall of the mounting plate 3121 has a first mounting notch 3123. The frame 10 includes a crossbeam 11 and a longitudinal beam 12. The crossbeam 11 extends along the width direction of the frame 10, and the longitudinal beam 12 extends along the length direction of the frame 10. The end of the longitudinal beam 12 is connected to the crossbeam 11. The first mounting notch 3123 is slidably engaged with the longitudinal beam 12. The moving block 3122 is provided with a second mounting notch 3124, and the moving block 3122 is slidably mounted on the mounting plate 3121 through the second mounting notch 3124. With the above structure, the first mounting notch 3123 is provided on the side wall of the mounting plate 3121, and the mounting plate 3121 is slidably engaged with the longitudinal beam 12 through the first mounting notch 3123. This allows the mounting plate 3121 to be slidably mounted on the frame 10, and the second mounting notch 3124 on the moving block 3122 allows it to be slidably mounted on the mounting plate 3121, thus ensuring the reliability of the sliding structure.

[0033] It should be noted that a first mounting hole is provided on the mounting plate 3121. After the mounting plate 3121 is moved to a suitable position, screws are inserted through the first mounting hole and abut against the longitudinal beam 12 to fix it. This can limit the mounting plate 3121 and prevent the mounting plate 3121 from continuing to slide.

[0034] The movable block 3122 is provided with a second mounting hole. After the movable block 3122 moves to a suitable position, a screw is inserted through the second mounting hole and abuts against the mounting plate 3121 to fix it. This can limit the movement of the movable block 3122 and prevent the movable block 3122 from continuing to slide.

[0035] like Figure 1 As shown, the adjusting component 31 includes multiple adjusting units 312, which are movably mounted on the frame 10 along its length. With this structure, multiple adjusting units 312 are provided, each movably mounted on the frame 10, and each adjusting unit 312 is equipped with a detection element 40. This allows each phase terminal on the energy meter to be connected to the calibrator via the detection element 40, ensuring the accuracy of the energy meter's calibration.

[0036] like Figure 1 and Figure 3 As shown, the detection element 40 includes a connecting base 41, a probe holder 42, and a detection probe 43. The connecting base 41 is connected to the moving block 3122. The first end of the probe holder 42 is detachably connected to the connecting base 41, and the second end of the probe holder 42 is rotatably connected to the first end of the detection probe 43. The second end of the detection probe 43 abuts against the phase terminal. With this structure, by connecting the connecting base 41 to the moving block 3122, detachably connecting the first end of the probe holder 42 to the connecting base 41, rotatably connecting the second end of the probe holder 42 to the first end of the detection probe 43, and abutting against the phase terminal, the detection element 40 can move together with the moving block 3122. Furthermore, the rotatable connection between the second end of the probe holder 42 and the first end of the detection probe 43 allows for angle adjustment of the detection probe 43 relative to the probe holder 42, ensuring that the detection probe 43 abuts against the phase terminal of the energy meter.

[0037] like Figure 3 As shown, a spherical groove 421 is provided on the second end of the probe holder 42. The detection probe 43 includes a spherical segment 431 and a detection segment 432 connected together. The spherical segment 431 is rotatably disposed in the spherical groove 421. A locking member 50 is provided on the probe holder 42 to limit the rotation angle of the spherical segment 431. With the above structure, the spherical segment 431 is rotatably disposed in the spherical groove 421. After the spherical segment 431 rotates to a suitable angle, the locking member 50 can lock the spherical segment 431, thereby limiting the spherical segment 431 to a certain rotation angle and preventing the spherical segment 431 from rotating.

[0038] like Figure 3As shown, the locking member 50 includes a limiting rod 51 and a locking ring 52. The spherical segment 431 has a plurality of limiting grooves spaced apart circumferentially along the spherical segment 431. The first end of the limiting rod 51 is movably inserted through the probe holder 42 and extends into the spherical groove 421. The first end of the limiting rod 51 can abut against one of the limiting grooves. The locking ring 52 is sleeved on the limiting rod 51 and locked in place with the probe holder 42 to limit the rotation angle of the spherical segment 431. With the above structure, multiple limiting grooves are provided on the spherical segment 431. The first end of the limiting rod 51 is movably inserted through the probe holder 42 and extends into the spherical groove 421. The first end of the limiting rod 51 can abut against one of the limiting grooves, so that the limiting rod 51 and the limiting groove can be locked together and fixed, thus preventing the spherical segment 431 from continuing to rotate. The locking ring 52 is sleeved on the limiting rod 51 and locked with the probe holder 42, thus limiting the rotation angle of the spherical segment 431.

[0039] It should be noted that a relative limiting block is provided at the opening of the probe holder 42 to prevent the rotation angle of the detection probe 43 from exceeding the maximum limit, which could lead to damage.

[0040] The connector 41 is equipped with an LED indicator light. When the detection probe 43 is in contact with the phase terminal on the energy meter and is conducting, the LED indicator light will light up to remind the operator that the connector 41 is in working condition, thus preventing accidental contact accidents caused by operator misconduct.

[0041] like Figure 2 As shown, the testing connection device for electricity meter inspection also includes a first position sensor 61, a second position sensor 62, and a display unit 63. Both the first position sensor 61 and the second position sensor 62 are mounted on the frame 10 to detect the positions of the adjusting member 31 and the moving member 21. The display unit 63 is connected to both the first position sensor 61 and the second position sensor 62 to display electricity meter information. With this structure, by setting the first position sensor 61 and the second position sensor 62, the first position sensor 61 can sense the position of the adjusting member 31, and the second position sensor 62 can sense the position of the moving member 21. This allows the electricity meter information to be displayed on the display unit 63, facilitating the determination of the electricity meter's model and size by the operator, and making it easier to connect the testing member 40 to the phase terminal of the electricity meter. This ensures the practicality of the testing connection device.

[0042] It should be noted that the testing connection device for electricity meter inspection also includes an intelligent identification module comprising: a connecting strap and a data processing unit; one end of the connecting strap is detachably connected to the frame 10, and the other end is detachably connected to the display unit 63; the display unit 63 is electrically connected to the data processing unit; the data processing unit acquires the installation position information of the moving part 21 transmitted by the second position sensor 62 and the installation position information of the adjusting part 31 transmitted by the first sensor, compares it with a preset threshold, determines the model of the electricity meter, displays the optimal installation position of the adjusting part 31 based on the information stored in the system background, and transmits it to the display unit 63 for the operator to view and adjust the installation position of the adjusting part 31.

[0043] Specifically, after the adjusting component 31 and the moving component 21 are installed in place, the first position sensor 61 and the second position sensor 62 respectively acquire their installation positions and transmit the data to the data processing unit. The data processing unit compares the received position data with a preset threshold and quickly identifies the model of the electricity meter based on the information stored in the system background. This process is usually completed within a few seconds. After identifying the electricity meter model, the data processing unit retrieves the optimal installation position data related to that model and displays it to the operator through the display unit 63. The operator can adjust the installation position of the adjusting component 31 by touching the display screen of the display unit 63, and can check the detection status and other relevant parameters at any time if needed. This setting method, based on the data stored in the system background, can automatically provide the optimal installation position, helping operators reduce the time cost of trial and error, thereby improving work efficiency.

[0044] like Figure 1 As shown, the movable component 21 includes a movable plate 211 and a connecting rod 212. The frame 10 includes a crossbeam 11 and a longitudinal beam 12. The crossbeam 11 extends along the width direction of the frame 10, and the longitudinal beam 12 extends along the length direction of the frame 10. The end of the longitudinal beam 12 is connected to the crossbeam 11. A third mounting notch 2111 is provided on the movable plate 211, and the third mounting notch 2111 is slidably engaged with the longitudinal beam 12. The first end of the connecting rod 212 is connected to the movable plate 211, and the second end of the connecting rod 212 can be connected to the electricity meter. With the above structure, the third mounting notch 2111 is provided on the movable plate 211, and the third mounting notch 2111 is slidably engaged with the longitudinal beam 12. This facilitates the movable plate 211 being movably mounted on the longitudinal beam 12. The first end of the connecting rod 212 is connected to the movable plate 211, and the second end of the connecting rod 212 can be connected to the electricity meter. This facilitates the connection of the movable component 21 to the electricity meter.

[0045] like Figure 1As shown, the movable plate 211 is provided with a threaded hole 2112 and a connecting hole 2113. The connecting rod 212 has a mounting hole. The testing connection device for testing the electricity meter also includes a first fastener and a second fastener. The first fastener passes through the threaded hole 2112 and is connected to the frame 10. The second fastener passes through the connecting hole 2113 and the mounting hole in sequence and is connected to the electricity meter. The end of the connecting rod 212 away from the movable plate 211 forms the electricity meter connection part. With the above structure, the connecting rod 212 is provided with a mounting hole. The first fastener passes through the threaded hole 2112, thereby connecting and fixing the movable plate 211 to the frame 10. The second fastener passes through the connecting hole 2113 and the mounting hole in sequence and is connected to the electricity meter. This ensures that the frame 10 is fixed to the electricity meter.

[0046] It should be noted that the testing connection device used for testing electricity meters also includes a hook. One end of the hook is rotatably connected to the frame 10, and the other end of the hook can be hung on the phase line of the electricity meter. The hook is equipped with a voltage detection port for connecting measuring equipment. The hook is hung on the phase line, and the working voltage of the phase line can be measured by connecting external measuring equipment through the voltage detection port, which is convenient and quick.

[0047] The hook includes an upper clamp, a lower clamp, and an operating handle. The upper and lower clamps are connected by a movable screw. The locking device on the upper clamp limits and locks the movable screw, thus keeping the upper and lower clamps relatively stationary and achieving the installation effect. The operating handle is an insulated handle to better protect the personal safety of the operator.

[0048] In this embodiment, the detection probe 43 is an elastic conductor. By setting the detection probe 43 as an elastic conductor, it can be elastically compressed when the detection probe 43 comes into contact with the phase terminal of the energy meter, ensuring the stability of the structure between the detection probe 43 and the phase terminal.
