It solves the problem that existing high-voltage non-destructive meter replacement devices lack a structure for auxiliary positioning of electricity meters during use, resulting in poor stability of electricity meters installed on the replacement device, which affects the reliability of the replacement process between old and new electricity meters and causes inconvenience.

[0006] In summary, this application provides the following technical solution: a high-voltage non-destructive meter replacement device, including a non-destructive meter replacement device body and a meter replacement component installed inside the non-destructive meter replacement device body, wherein positioning components are provided on both the left and right sides of the non-destructive meter replacement device body.

The connecting rods will then drive the positioning plate to move, thereby achieving the adjustment of the position of the positioning plate.

[0015] Furthermore, a spring is abutted at the end of the threaded sleeve away from the rotating shaft, and the spring is sleeved on the outer wall of the threaded rod.

[0016] The beneficial effects of adopting the above-mentioned further solution are: when the threaded sleeve moves, it can compress the spring, and the spring provides elastic support for the threaded sleeve, which improves the stability of the structure and ensures the stable clamping of the energy meter by the clamping plate.

[0017] Furthermore, a mounting plate is provided on the outer side of the non-destructive meter replacement instrument body. The upper part of the mounting plate is fixedly connected to the mounting box. A fixing screw is inserted into the inner side of the mounting plate, and the fixing screw is threadedly connected to the inner side of the non-destructive meter replacement instrument body.

[0018] The advantages of adopting the above-mentioned further solution are: the mounting plate and fixing screws make it easy to install the fixing box on the outside of the non-destructive meter replacement instrument body, and it is also easy to disassemble and use.

[0019] Furthermore, a slider is fixedly connected to the outer wall of the connecting rod, and a fixing plate is fixedly connected to the inside of the mounting box. A groove adapted to the slider is opened on the inner side of the fixing plate, and the slider is slidably connected to the inner side of the groove.

[0020] The beneficial effect of adopting the above-mentioned further solution is that the cooperation between the slider and the inner groove of the fixed plate can guide the connecting rod, so that the connecting rod and the positioning plate can maintain a stable movement trajectory, thereby improving the stability of the structure.

[0021] Furthermore, a flexible pad is provided on the outer wall of the positioning plate, and the flexible pads between the two positioning plates are arranged correspondingly to each other.

[0022] The beneficial effect of adopting the above-mentioned further solution is that the flexible pad can prevent the positioning plate from making hard contact with the electricity meter, thereby preventing wear on the outer wall of the electricity meter.

[0023] Compared with the prior art, this application provides a high-voltage non-destructive meter replacement instrument, which has the following beneficial effects:

[0024] This high-voltage non-destructive meter replacement device uses positioning components on both sides of the device body to assist in clamping the new and old electricity meters. Rotating the rotating shaft drives the threaded rod to rotate, which in turn moves the threaded sleeve. The threaded sleeve moves the adjusting rod, causing the two connecting rods to move closer together. The connecting rods then move the positioning plates, bringing the two positioning plates closer together to assist in clamping the electricity meter, ensuring stable installation and reliability during the replacement process. It is highly practical and solves the problem of existing high-voltage non-destructive meter replacement devices lacking an auxiliary positioning structure for the electricity meter, resulting in poor stability of the meter installed on the device and affecting the reliability and inconvenience of the replacement process.

[0031] Please see Figures 1 to 4 This embodiment of a high-voltage non-destructive meter replacement device includes a non-destructive meter replacement device body 1 and a meter replacement component 2 installed inside the non-destructive meter replacement device body 1. The inner side of the non-destructive meter replacement device body 1 is provided with a tool storage slot 3, which facilitates the storage of wire harness tools and improves ease of use.

[0032] In this embodiment, positioning components are provided on both the left and right sides of the non-destructive meter replacement device body 1. The positioning components on both sides are used to clamp the new meter and the old meter respectively.

[0033] It should be noted that the meter replacement assembly 2 consists of a voltage fuse, a fixing point for the new meter position energy meter, a fixing point for the old meter position energy meter, a current and voltage display for the new meter position, a current and voltage display for the old meter position, a current open circuit audible and visual alarm, a current open circuit reset button, a current misconnection audible and visual alarm, a current loop continuity indicator, a 3P3W / 3P4W button, a power switch button, a power-on button for the new meter position, a power-on button for the old meter position, and a power-on meter reading button.

[0034] The new meter mounting point and the old meter mounting point are used to insert the new meter and the old meter, respectively. The two sets of positioning components are located on one side of the new meter mounting point and the old meter mounting point, respectively. The voltage fuse is used to protect against short circuits in the three-phase voltage circuit of the equipment. The current and voltage display at the new meter mounting point is used to display the voltage and current values ​​of each phase power circuit at the new meter mounting point. The current and voltage display at the old meter mounting point is used to display the voltage and current values ​​of each phase power circuit at the old meter mounting point.

[0035] Among them, the current open circuit audible and visual alarm is a CT open circuit alarm, which sounds an alarm when the CT is open; the current open circuit reset button is a CT open circuit reset button, which can clear the alarm when the CT is connected; the current open circuit audible and visual alarm is a current misconnection alarm, which sounds an alarm when the current circuit is incorrectly connected to the voltage power supply; the current circuit continuity indicator light is green when the current circuit is properly connected; the 3P3W / 3P4W button is pressed when replacing a 3P3W energy meter and released when replacing a 3P4W energy meter; the power switch button is powered on when pressed and powered off when released; the new meter position power button is powered on when pressed and powered off when released; the old meter position power button is powered on when pressed and powered off when released.

[0036] In this embodiment, the positioning components include a mounting box 4 detachably mounted on the outside of the non-destructive meter replacement instrument body 1, a rotating shaft 5 rotatably mounted inside the mounting box 4, a threaded rod 7 fixedly connected to one end of the rotating shaft 5, a threaded sleeve 8 threadedly mounted on the outside of the threaded rod 7, two adjusting rods 9 respectively hinged to both sides of the threaded sleeve 8, two connecting rods 10 respectively hinged to the other ends of the two adjusting rods 9 and extending to the outside of the mounting box 4, and two positioning plates 11 respectively fixedly connected to the outside of the two connecting rods 10. The positioning components on both sides of the non-destructive meter replacement instrument body 1 can achieve auxiliary clamping of the new and old electricity meters. By rotating the rotating shaft 5, the threaded rod 7 is rotated, which in turn moves the threaded sleeve 8. The threaded sleeve 8 can move the adjusting rod 9, thereby moving the two connecting rods 10 closer together. The connecting rods 10 then move the positioning plates 11, causing the two positioning plates 11 to move closer together to assist in clamping the electricity meters, ensuring stable installation of the electricity meters, and thus ensuring reliability during the replacement of old and new electricity meters, making it highly practical.

[0037] The outer wall of the rotating shaft 5 is connected to the inner wall of the mounting box 4 via bearings, and the end of the threaded rod 7 away from the rotating shaft 5 is also connected to the inner wall of the mounting box 4 via bearings. These bearings provide rotational support for the rotating shaft 5 and the threaded rod 7, improving structural stability and ensuring stable rotational adjustment of both. Simultaneously, an adjustment knob 6 is fixedly connected to the end of the rotating shaft 5 away from the threaded rod 7. Located on the outside of the mounting box 4, the adjustment knob 6 facilitates rotational adjustment of the rotating shaft 5. Rotating the adjustment knob 6 causes the rotating shaft 5 to rotate, which in turn rotates the threaded rod 7 and moves the threaded sleeve 8. The threaded sleeve 8 then moves the adjustment rod 9, causing the two connecting rods 10 to move closer together. The connecting rods 10 then move the positioning plate 11, thus adjusting the position of the positioning plate 11.

[0038] It should be noted that a slider 16 is fixedly connected to the outer wall of the connecting rod 10, and a fixing plate 17 is fixedly connected inside the mounting box 4. The inner side of the fixing plate 17 has a groove that matches the slider 16. The slider 16 is slidably connected to the inner side of the groove. The cooperation between the slider 16 and the groove in the fixing plate 17 guides the connecting rod 10, enabling the connecting rod 10 and the positioning plate 11 to maintain a stable movement trajectory, thus improving the stability of the structure. In addition, a flexible pad 12 is provided on the outer wall of the positioning plate 11. The flexible pads 12 between the two positioning plates 11 are correspondingly arranged. The flexible pads 12 prevent the positioning plate 11 from making hard contact with the electricity meter, thereby preventing wear on the outer wall of the electricity meter.

[0039] It should be added that the end of the threaded sleeve 8 away from the rotating shaft 5 is abutted against the spring 15. The spring 15 is sleeved on the outer wall of the threaded rod 7. When the threaded sleeve 8 moves, it can compress the spring 15. The spring 15 plays an elastic support role for the threaded sleeve 8, which improves the stability of the structure and ensures the stable clamping of the energy meter by the clamping plate 11.

[0040] In this embodiment, a mounting plate 13 is provided on the outer side of the non-destructive meter replacement instrument body 1. The upper part of the mounting plate 13 is fixedly connected to the mounting box 4, and a fixing screw 14 is inserted into the inner side of the mounting plate 13. The fixing screw 14 is threadedly connected to the inner side of the non-destructive meter replacement instrument body 1. The mounting plate 13 and the fixing screw 14 facilitate the installation of the fixing box 4 on the outer side of the non-destructive meter replacement instrument body 1, and are easy to disassemble and use.

[0041] The working principle of the above embodiments is as follows:

[0042] In use, the positioning components on both sides of the non-destructive meter replacement instrument body 1 can assist in clamping the new and old electricity meters. By rotating the rotating shaft 5, the threaded rod 7 is rotated, which in turn moves the threaded sleeve 8. The threaded sleeve 8 can move the adjusting rod 9, thereby moving the two connecting rods 10 closer together. The connecting rods 10 will then move the positioning plate 11, so that the two positioning plates 11 move closer together to assist in clamping the electricity meter, ensuring the stable installation of the electricity meter, and thus ensuring the reliability of the replacement process of the new and old electricity meters. It is highly practical.
