Abstract
Description
Technical Field
[0001] This utility model relates to the field of auxiliary technology for testing electricity meters, and more specifically, to a tabletop auxiliary device for testing the influence of ambient temperature on smart electricity meters. Background Technology
[0002] Smart meters are one of the basic devices for data acquisition in smart grids. They are responsible for the collection, measurement, and transmission of raw electrical energy data and are the foundation for information integration, analysis and optimization, and information display. When smart meters are put into use, their performance needs to be tested.
[0003] However, existing technologies have some problems: in the performance testing of smart meters, the influence of ambient temperature on their metering accuracy, clock accuracy, and other performance aspects is crucial. Current temperature influence tests often place the smart meter directly in a high and low temperature test chamber without dedicated auxiliary devices. This approach has several issues: firstly, the lack of a reliable fixing structure for the meter means that it may shift or even tip over under temperature changes or airflow disturbances within the test chamber, affecting the accuracy of the test results; secondly, the wiring connection between the meter and the test equipment is inconvenient, with messy wires easily becoming tangled, and loose wiring during the test can interfere with normal operation; furthermore, existing placement methods lack protective measures for the meter, making it susceptible to damage from impacts during testing. Therefore, we propose a tabletop auxiliary device for testing the environmental temperature influence of smart meters. Utility Model Content
[0004] One objective of this invention is to provide a new technical solution for a tabletop auxiliary device for testing the influence of ambient temperature on smart energy meters.

[0026] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values of the components and steps set forth in these embodiments do not limit the scope of the present invention.
[0027] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.
[0028] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.
[0029] In all the examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.
[0030] like Figures 1-6 As shown, a tabletop auxiliary device for testing the influence of ambient temperature on smart energy meters includes a stand plate 1. A circuit box 2 is fixedly installed at the rear end of the stand plate 1. The circuit box 2 is provided with terminal blocks 3. Both the stand plate 1 and the circuit box 2 are provided with signal terminals 21 and voltage terminals 22 for signal transmission through circuit connection. A square frame 4 is fixedly installed on the front of the stand plate 1. A slider 5 is slidably connected inside the square frame 4. A current column 6 is provided on the top of the slider 5. The current column 6 and the slider 5 are connected by a disassembly assembly for quick disassembly and assembly of the current column 6. The slider 5 and the square frame 4 are also connected by a limiting assembly, and the position of the slider 5 on the square frame 4 can be adjusted by the limiting assembly.
[0031] By adjusting the position of slider 5 on box 4 and fixing slider 5 by limiting component, and then installing the energy meter on current column 6, smart energy meters of different specifications and sizes can be installed and fixed to ensure that the energy meter remains stable during the test.
[0032] The above-mentioned tabletop auxiliary device for testing the influence of ambient temperature on smart energy meters includes a limiting component including a sliding plate 7. The sliding plate 7 is located at the front end of the frame 4. A bolt 8 is movably inserted into the sliding plate 7. The bolt 8 is threadedly connected to the slider 5. A slide rail 9 is provided on the frame 4, and the sliding plate 7 is slidably connected in the slide rail 9.
[0033] By rotating bolt 8 from the inside to the outside of slider 5, the slide plate 7 and slide rail 9 can be loosened, thereby moving slider 5 to adjust its position on the frame 4. After adjustment, rotate bolt 8 again to screw it inward, so that slide plate 7 can be tightly attached to the inner wall of slide rail 9, thereby limiting slider 5. This makes it easy to adjust the position of slider 5 to fix the electricity meter according to different specifications and sizes.
[0034] The aforementioned tabletop auxiliary device for testing the influence of ambient temperature on smart energy meters has a square-shaped slide plate 7 with anti-slip textures on its inner surface.
[0035] The anti-slip texture design on the inner surface of the skateboard 7 enhances the limiting effect on the slider 5 when the skateboard 7 is in close contact with the inner wall of the slide rail 9.
[0036] The above-mentioned tabletop auxiliary device for testing the influence of ambient temperature on smart energy meters includes a disassembly component comprising a positioning block 10, which is fixedly installed on the top of the slider 5. The current column 6 is movably sleeved on the outer surface of the positioning block 10. A side groove 11 is provided on the positioning block 10. A pin 12 is movably inserted into the current column 6. One end of the pin 12 extends into the side groove 11, and the other end of the pin 12 is fixedly connected to a pull handle 13.
[0037] By pulling the handle 13 to pull one end of the pin 12 out of the side groove 11, the restriction on the current column 6 can be released, so that the current column 6 can be removed from the positioning block 10. This makes it easier for staff to remove the excess current column 6 when the model of the electricity meter does not require a large number of current columns 6, thus avoiding obstruction to the installation of the electricity meter.
[0038] The above-mentioned tabletop auxiliary device for testing the influence of ambient temperature on smart energy meters has a spring 14 movably sleeved on the outer surface of the pin 12, and the two ends of the spring 14 are respectively fixedly connected to the current column 6 and the pull handle 13.
[0039] By setting the spring 14 to a stretched state, the spring 14's elasticity will cause the pin 12 to tend to move into the side groove 11, thereby ensuring that one end of the pin 12 is stably kept inside the side groove 11, thus guaranteeing the limiting effect on the current column 6.
[0040] The above-mentioned tabletop auxiliary device for testing the influence of ambient temperature on smart energy meters has a threaded rod 15 rotatably connected to the front of the upright plate 1, a clamping plate 16 threadedly sleeved on the outer surface of the threaded rod 15, a guide rod 17 fixedly installed on the front of the upright plate 1, and the clamping plate 16 movably sleeved on the outer surface of the guide rod 17.
[0041] After the electricity meter is installed on the current column 6, the operator can rotate the threaded rod 15 so that the clamping plate 16 approaches and contacts the electricity meter under the guidance of the guide rod 17, thereby clamping the electricity meter and further limiting the electricity meter's position, thus improving the stability of the electricity meter during testing.
[0042] The aforementioned tabletop auxiliary device for testing the influence of ambient temperature on smart energy meters has a cylindrical guide rod 17 with a lubricating layer coated on its surface.
[0043] By providing a lubricating layer on the surface of the guide rod 17, the clamping plate 16 can slide more smoothly along the outer surface of the guide rod 17.
[0044] The aforementioned tabletop auxiliary device for testing the influence of ambient temperature on smart energy meters has a shim 18 fixedly installed on the clamping plate 16, the width of the shim 18 being the same as the width of the clamping plate 16.
[0045] The gasket 18 can be made of rubber, which provides good protection for the electricity meter when it is clamped due to its soft nature.
[0046] The above-mentioned tabletop auxiliary device for testing the influence of ambient temperature on smart energy meters has a terminal block 3 located at the center of the top of the circuit box 2, and a screw cap 19 is threaded onto the outer surface of the terminal block 3.
[0047] When the device is connected to the test equipment via terminal 3, the cable end can be wrapped around terminal 3, and then the cap 19 can be tightened to fix the cable, thereby tidying up and fixing the line, effectively preventing the line from getting tangled and loose.
[0048] The above-mentioned tabletop auxiliary device for testing the influence of ambient temperature on smart energy meters has a protective shell 20 fixedly installed on the upright plate 1. The protective shell 20 is U-shaped.
[0049] The protective casing 20 is designed to protect the smart energy meter during the test operation, preventing damage caused by accidental impact.
[0050] Working principle and usage process of this utility model:
[0051] First, the staff adjusts the number and position of the current columns 6 according to the model and size of the electricity meter. By pulling the handle 13, one end of the pin 12 can be pulled out from the side groove 11, releasing the restriction on the current columns 6 and allowing them to be removed from the positioning block 10. This facilitates the removal of excess current columns 6 when the electricity meter model does not require a large number, avoiding obstruction to the meter's installation. Then, by rotating the bolt 8 from the inside out of the slider 5, the sliding plate 7 and the slide rail 9 are loosened, allowing the slider 5 to be moved and its position adjusted on the frame 4. After adjustment, the bolt 8 is rotated again to screw the slider 5 inward, ensuring the sliding plate 7 is tightly against the inner wall of the slide rail 9, thus limiting the slider 5. This allows for adjusting the position of the slider 5 according to different meter sizes to secure the electricity meter. The electricity meter can then be installed. On the current column 6, rotate the threaded rod 15 so that the clamping plate 16 drives the gasket 18 to clamp the energy meter to improve stability. After the energy meter is installed, connect the voltage, current and signal lines of the auxiliary device to the test equipment through the signal terminal 21 and voltage terminal 22 on the circuit box 2. The connecting wires inserted on the voltage terminal 22 on the upright plate 1 are clamped to the voltage terminals of the energy meter through the voltage clamps. After the connection is completed, the test can be carried out. When conducting the test of the influence of ambient temperature on the metering accuracy, connect the pulse signal clamp of the signal terminal 21 of the upright plate 1 to the corresponding electrical pulse output terminal of the energy meter. When conducting the test of the influence of ambient temperature on the clock accuracy, connect the multi-function signal clamp of the signal terminal 21 of the upright plate 1 to the corresponding multi-function output terminal of the energy meter. At the same time, connect the connecting wire of the circuit box 2 to the signal terminal 21 to ensure the stability of the energy meter and the stability of the circuit during the test, and improve the reliability and safety of the test.
