DETAILED DESCRIPTION

[0025] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0026] In recent years, the construction of new power systems has been in full swing, and the quality of supporting equipment, as a top priority, has received widespread attention. For example, the quality control of materials entering the grid has always been a focus of attention.

[0027] Material sampling inspection is a key link, and the workload is increasing year by year. Faced with the development pressure of continuously increasing inspection tasks, there is also the prominent contradiction that many electrical test operations are complicated and have many steps.

[0028] In order to solve the above problems, this manual provides a multi-terminal insulated grounding wire reel instrument, which aims to provide grounding equipment that can conduct experiments quickly and conveniently, thereby improving the safety and reliability of the experiments. Figure 1 and Figure 2 Schematic diagram of the structure of the multi-terminal insulated grounding wire reel according to the embodiment of the present invention from two different perspectives, as shown in FIG. Figure 1 and Figure 3 As shown, the grounding wire reel instrument specifically includes:

[0029] The enclosure 1 forms the main body of the device, housing the power supply and main controller. A power switch 12 and output terminals 7 are also located on the enclosure. The grounding reel instrument's internal system circuits are isolated from grounding-related circuits and has its own 24V power supply. The main controller is electrically connected to the power supply, the power switch is electrically connected to the power supply, and the output terminals 7 are electrically connected to the main controller.

[0030] Several take-up reels 3 are arranged in the box body 1 , each of which is wound with a retractable grounding wire 6 , and each of which is electrically connected to a main controller in the box body 1 .

[0031] Several wiring ports 2, input terminals 5, and indicator lights 4 are provided on the housing 1. Each take-up reel 3 has a corresponding wiring port 2, input terminal 5, and indicator light 4 on the housing 1. One end of the retractable grounding wire 6 is configured as a ground terminal, which passes through the corresponding wiring port 2 and slides into connection with the wiring port 2. The input terminal 5 and indicator light 4 are both electrically connected to the main controller. In this embodiment, the wiring port 2 is configured with a relatively wide diameter, which not only facilitates the passage of the corresponding ground terminal, but also facilitates the sliding of the retractable grounding wire 6 at the wiring port 2.

[0032] The grounding cable reel instrument also has multiple connection ports 2, which can be connected to test equipment, test samples, safety protection grounding, shielding grounding, etc. at the same time to carry out multiple tests at the same time.

[0033] The housing 1 is provided with indicator lights 4 corresponding to the number of connection ports 2 or 3. When the connection port 2 corresponding to the indicator light 4 is successfully grounded, the corresponding indicator light will illuminate. Conversely, when the grounding fails, the indicator light will not illuminate. The indicator light 4 can also be used in conjunction with a buzzer, so that when the device experiences a grounding failure, it is convenient to check which specific grounding line has failed.

[0034] See also Figure 3 More specifically, each of the aforementioned wiring ports 2 is equipped with a take-up reel 3, which includes a base 31, a wheel 32, and a winding shaft 33. The base 31 is fixed to the interior of the housing 1, and a wheel 32 is provided on the base 31. The center of the wheel 32 is rotatably connected to the winding shaft 33, and the retractable grounding wire 6 is wound around the winding shaft 33. The take-up reel 3 thus has the following functions: the winding shaft 33 uses double-sided steel ball bearings and an extra-long-stroke steel coil spring to ensure durability during use; the wiring reel 3 is electrically connected to the main controller within the housing 1 via a connecting wire 34, and can count the retractable distance of the retractable grounding wire 6, achieving intermittent self-locking of the retractable grounding wire 6. A stop ball made of plastic or other materials can also be configured for ease of use. In this embodiment, the retractable grounding wire 6 is made entirely of transparent wire. This allows the retractable grounding wire 6 to be wound around the take-up reel 3 while providing advantages such as visualization, warning, and portability, helping experimenters to instantly determine the usage status of the grounding wire.

[0035] In order to prevent the telescopic grounding wires 6 from being entangled with each other, a plurality of blocking members 35 are provided on the wheel 32. The blocking members 35 are distributed on the wheel 32 around the winding shaft 33. The telescopic grounding wire 6 is located between the blocking members 35 and the winding shaft 33. In this way, multiple take-up reels 3 can automatically arrange the wires on the same layer.

[0036] In this embodiment, the end of the grounding end of the telescopic grounding wire 6 is provided with at least one of a plug-in connector, a crimp connector, and a welding connector.

[0037] An input ground wire 8 and an output ground wire 9 are also provided on either side of the housing 1, both of which are electrically connected to the main controller. Input ground wire 8 connects to input terminal 5, forming a loop to detect abnormalities in the circuit of telescopic ground wire 6. Output ground wire 9 also connects to output terminal 7, forming a loop to detect abnormalities in the circuit of telescopic ground wire 6.

[0038] In this embodiment, a hanging bracket is provided on each side of the box body 1, and is used to hang the above-mentioned input grounding wire 8 and output grounding wire 9 respectively, so that the input grounding wire 8 and the output grounding wire 9 can be hung on the box body 1 in a winding state.

[0039] In this embodiment, a transparent window 10 is provided on the box body 1. The transparent window 10 is provided to facilitate the test personnel to see the usage of each take-up reel 3 inside.

[0040] In this embodiment, a buzzer is provided on the housing 1 and is electrically connected to the main controller. The buzzer is used to alert the experimenter. When the grounding wire reel is in normal use, the buzzer does not sound. When the buzzer sounds, it indicates that at least one grounding line has failed, and an inspection is required to confirm that the grounding state of the grounding wire reel is correct.

[0041] The grounding wire reel instrument is scalable and can be upgraded later through an integrated design of the electrometer and the grounding wire hook. When the grounding wire is hooked, the electricity can be tested at the docking point to avoid excessive floating potential affecting the safe operation of the equipment.

[0042] For easy portability, in this embodiment, a handle 13 is installed on the box 1 to facilitate the tester to move the grounding wire reel instrument to the test site.

[0043] Taking into account the need to move the device over long distances in some scenarios, in this embodiment, a pull rod sleeve 14 is provided on one side of the box body 1, and a pull rod 15 is slidably connected to the pull rod sleeve 14. By arranging the pull rod 15 on the box body 1, the grounding wire reel instrument can be conveniently transported over long distances.

[0044] At the same time, considering the problem of mobility, a universal wheel 11 with a locking function is provided at the bottom of the box body 1.

[0045] When in use, first move the grounding wire reel instrument to a stable platform and fix the equipment; then pull out the ground bus from the grounding wire reel instrument and connect it to the ground bus. To ensure the successful grounding of the bus, two ground buses are configured in this embodiment, which can be used selectively; then connect the retractable grounding wire 6 that needs to be connected to the equipment through various types of interfaces; then start the power switch 12, and the grounding wire reel instrument starts to monitor whether each retractable grounding wire 6 used is connected. The corresponding indicator light 4 on the grounding port 2 lights up, indicating that the corresponding retractable grounding wire 6 is successfully grounded. The indicator light is off, indicating that the corresponding retractable grounding wire 6 is not enabled or the grounding fails. When the buzzer sounds, it means that an interface has failed to be grounded. At this time, it is necessary to check which interface's retractable grounding wire 6 is connected and the indicator light 4 is off, indicating that the retractable grounding wire 6 has failed to be grounded, and the corresponding retractable grounding wire 6 is re-grounded.

[0046] The multi-terminal insulated grounding wire reel instrument of the present invention has several wire reels 3 in the box body 1, each of which is wound with a retractable grounding wire 6, and each wire reel 3 has a corresponding wiring port 2, an input wiring terminal 5 and an indicator light 4 on the box body 1. One end of the retractable grounding wire 6 is set as the grounding terminal, and the grounding terminal will pass through the corresponding wiring port 2 and be slidably connected to the wiring port 2. The grounding wire reel instrument also has multiple wiring ports 2, which can be connected to testing equipment, testing samples, safety protection grounding, shielding grounding, etc. at the same time to carry out multiple tests at the same time. The grounding wire reel instrument is used to solve the problems of large grounding volume and complicated grounding process of test equipment used in the power system. Since the wiring end of the retractable grounding wire 6 passes through the wiring port 2, the test grounding problem is solved by multiple visual wire reels 3, and each grounding status during the test is automatically checked and verified, and is clearly visible, which can greatly improve the grounding work efficiency, while also ensuring that there are no errors in the grounding process, thereby improving the safety and reliability of the test.
