DETAILED DESCRIPTION

[0019] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0020] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “described” as used herein may also mean including the plural forms. The terms “comprising,” “including,” “containing,” and “having” are inclusive and therefore indicate the presence of the stated features, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The method steps, processes, and operations described herein are not construed as requiring them to be performed in a particular order described or illustrated unless the order of performance is explicitly indicated. It should also be understood that additional or alternative steps may be used.

[0021] Although terms such as first, second, third, etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence. Therefore, the first element, component, region, layer, or segment discussed below may be referred to as the second element, component, region, layer, or segment without departing from the teachings of the exemplary embodiments.

[0022] For ease of description, spatial relative terms may be used in the text to describe the relationship of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "over," etc. The meaning of such spatial relative terms includes different orientations of the device in use or operation, in addition to the orientation depicted in the figure. For example, if the device in the figure is flipped, then an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0023] Example 1:

[0024] like Figure 1 and Figure 2 As shown, the three-phase electricity meter replacement and error verification auxiliary device provided in this embodiment includes a three-phase electricity meter 1, a junction box 2, a short circuit 3, an assembly box 4, and a calibrator 5. The wires are connected to the three-phase electricity meter 1 through the junction box 2. The short circuit 3 can be inserted into the junction box 2 to disconnect the power to the three-phase electricity meter 1. The calibrator 5 is embedded in the assembly box 4 and is used to perform error verification on the three-phase electricity meter 1. In actual use, both the three-phase meter 1 and the junction box 2 are fixedly installed. The wires entering the three-phase meter 1 are connected through the junction box 2. The short circuit 3 is set to correspond to the terminals of the junction box 2. When the three-phase meter 1 malfunctions and needs maintenance, the short circuit 3 is inserted into the junction box 2 to short-circuit the terminals of the junction box 2, thereby de-energizing the three-phase meter 1 and facilitating the disconnection of the three-phase meter 1 by the staff. After disconnection, the three-phase meter 1 needs to be calibrated. At this time, the assembly box 4 carried by the staff is used, and the calibrator 5 embedded in the assembly box 4 is used to calibrate the three-phase meter 1.

[0025] In this embodiment, the assembly box has a first storage box, a second storage box, and a third storage box. In actual use, when the staff maintains the three-phase meter 1, they need to carry the assembly box 4. The assembly box 4 needs to be equipped with a calibrator 5, connecting wires, a short circuit breaker 3, and a spare meter 6. The spare meter 6, connecting wires, and short circuit breaker 3 are respectively provided with a first storage box 41, a second storage box 42, and a third storage box 43.

[0026] In this embodiment, the first storage box 41 is used to hold the connecting wire, the second storage box 42 is used to hold the circuit breaker 3, and the third storage box 43 is used to hold the spare meter 6. In actual use, the connecting wire is used to connect the calibrator 5 and the three-phase meter 1, the circuit breaker 3 is used to disconnect the power to the three-phase meter 1, and the spare meter 6 is used to replace the three-phase meter 1.

[0027] In this embodiment, the junction box 2 has an opening, and a cover plate 21 is fastened to the opening. In actual use, the opening of the junction box 2 corresponds to the wiring terminals of the junction box 2. The circuit breaker 3 short-circuits the wiring terminals of the junction box 2 by inserting it into the opening. To prevent accidental electric shock, a cover plate 21 is fastened to the opening.

[0028] In this embodiment, the cover plate 21 is provided with anti-slip strips 211. In actual use, by providing anti-slip strips 211 on the cover plate 21, it is convenient for workers to open and close the cover plate 21, making operation easier.

[0029] Example 2:

[0030] like Figure 1 As shown, based on Embodiment 1, the circuit breaker 3 is equipped with a handle 31. In actual use, the handle 31 facilitates the operator's insertion and removal of the circuit breaker 3.

[0031] In this embodiment, the handle 31 is provided with an insulating pad 311. In actual use, by providing the insulating pad 311 on the handle 31, insulation support is provided to prevent workers from accidentally getting electric shock when operating the circuit breaker 3.

[0032] In this embodiment, the circuit breaker 3 is also equipped with indicator lights 32. In actual use, three indicator lights 32 are set for each of the three phase lines. When the circuit breaker 3 is inserted into the junction box 2, the circuit breaker 3 connects the three phase lines in the junction box 2, causing the three-phase meter 1 to be de-energized. At this time, the indicator lights 32 are turned on, making it convenient for staff to directly check whether the circuit breaker 3 is working properly.

[0033] All technical features in this embodiment can be freely combined according to actual needs. The above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it.
