[0028] The present application will be described in further detail below in conjunction with the drawings.

[0029] As Figure 4 , Figure 5The phase sequence board 100 shown includes an identification member 11, a communication member 12, and a clamping member 13. The identification member 11 includes a first identification member 111, a second identification member 112, and a third identification member 113. The communication member 12 is electrically connected to the first identification member 111, the second identification member 112, or the third identification member 113. The clamping member 13 is connected to the communication member 12. The clamping member 13 includes a first part 131 and a second part 132. Both the first part 131 and the second part 132 are connected to the communication member 12. The first part 131 and the second part 132 are mirror images of each other. A clamping channel 01 is formed between the first part 131 and the second part 132. The clamping channel 01 is used to clamp a line. The clamping member 13 is used to clamp and connect to the line. The first part 131 and the second part 132 are oppositely arranged and can elastically move relative to each other. The communication member 12 is used to connect a chip device 200. The identification member 11 is used for a worker to identify the phase sequence of the line. Through the above design, when the worker installs the phase sequence board 100, the phase sequence board 100 is fixed to one end of an operating rod. The line is clamped between the first part 131 and the second part 132. Under the clamping action of the first part 131 and the second part 132, the first part 131 and the second part 132 move away from each other, so that the line is clamped in the clamping channel 01. The process does not require the worker to perform a high-altitude operation, and does not require power to be cut off.

[0030] Please refer to Figure 4 , Figure 5 The inside of the clamping channel 01 is provided with a clamping groove 04. The clamping groove 04 can be attached to the surface of the line. Under the elastic clamping action of the first part 131 and the second part 132, the line can be clamped in the clamping groove 04, thereby achieving rapid fixing of the phase sequence board 100. The above operation process is simple. The operating rod is used for operation without the need for the worker to perform a high-altitude operation or power cut-off. The safety of the worker is ensured, and the operation difficulty of the phase sequence board 100 assembly is reduced.

[0031] In summary, the above phase sequence board 100 reduces the operation difficulty of the phase sequence board 100 installation.

[0032] It should be noted that the above operating rod is a common operating tool in electrical work. The operating rod is an insulating rod. The worker can assemble some parts of the line through the operating rod. During assembly, the parts to be assembled are detachably fixed to one end of the operating rod. Then the worker can install the assembled parts on the line at a high place through the operating rod. The installation of the parts through the operating rod can keep a sufficient safety distance between the worker and the line. The phase sequence board 100 provided by the present application is clamped and fixed to the line through the operating rod.

[0033] The technical details of each component will be introduced one by one below.

[0034] In some embodiments, the morphological structures of the first identification member, the second identification member, and the third identification member are all in the form of letters.

[0035] As shown in Figure 1 , Figure 2 , the first identification member 111 is in an A-shaped structure, the second identification member 112 is in a B-shaped structure, and the third identification member 113 is in a C-shaped structure. The phase sequence can be represented by the well-known A, B, and C rules, and the staff can identify the phase sequence of the line by identifying the A, B, and C rules, which are not easily affected by the natural environment and are easy to identify.

[0036] In other embodiments, the first identification member, the second identification member, and the third identification member are all in a digital form. For example, the first identification member is in a "1" form, the second identification member is in a "2" form, and the third identification member is in a "3" form. The staff can identify the phase sequence of the line by identifying the rules of the numbers 1, 2, and 3, which are not easily affected by the natural environment and are easy to identify.

[0037] Of course, the first identification member, the second identification member, and the third identification member can also be other symbols or patterns with general rules.

[0038] In some embodiments, as shown in Figure 1 , Figure 2 , the surfaces of the first identification member 111, the second identification member 112, and the third identification member 113 are in an arc surface structure. The phase sequence board 100 is easily affected by the airflow in the natural environment and is prone to swing, which interferes with the identification of the staff. The surfaces of the first identification member 111, the second identification member 112, and the third identification member 113 are designed to be in an arc surface structure. When the airflow flows through the phase sequence board 100, it can flow along the arc surface structure, thereby reducing the impact of the airflow on the phase sequence board 100, and thereby reducing the influence of the airflow on the phase sequence board 100, which is conducive to the identification of the phase sequence board 100 by the staff.

[0039] In some embodiments, the first identification member 111, the second identification member 112, and the third identification member 113 are made of glass and have LED light beads inside, and the LED light beads are electrically connected to the communication member 12. When it is night, the LED light beads can emit light to facilitate the identification of the phase sequence board 100 by the staff, and the glass material is very corrosion-resistant and not prone to weathering, greatly improving the service life of the phase sequence board 100. In addition, the surface of the glass material is also relatively smooth, and the airflow in the natural environment is more easily flowed through the surface of the phase sequence board 100, which helps to reduce the swing of the phase sequence board 100 in the natural environment due to the airflow.

[0040] Further, the light-emitting colors of the LED light beads inside the first identification member 111, the second identification member 112, and the third identification member 113 are different, and at night, the workers can identify the phase sequence of the line by identifying the light-emitting colors.

[0041] Still further, the first identification member 111, the second identification member 112, and the third identification member 113 are made of glass with different colors, and the workers can identify the phase sequence of the line by identifying the colors. Since the chemical properties of the glass are very stable, the colors of the phase sequence board 100 will not fade in the natural environment, which not only prolongs the service life of the phase sequence board 100 but also enhances the identification degree of the phase sequence board 100.

[0042] In some embodiments, as shown in Figure 4 , Figure 5 The first part 131 and the second part 132 are inserted into the insertion slot 02. The first part 131 and the second part 132 are inserted into the insertion slot 02 in an interference fit manner. In actual use, different models of clamping members 13 with different types of clamping slots are needed to ensure the firmness of the clamping member 13 for lines with different diameters. The interference fit structure of the first part 131 and the second part 132 is simple and convenient for replacing the clamping member 13.

[0043] In some embodiments, as shown in Figure 4 , Figure 5 The first part 131 includes an insertion end 1311, a deformation part 1312, a clamping part 1313, and a guide part 1314. The deformation part 1312 is connected to the clamping part 1313 and the insertion end 1311, respectively. The guide part 1314 is arranged at one end of the clamping part 1313 away from the deformation part 1312. The second part 132 is arranged opposite to the first part 131 and has a mirror image structure. The insertion end 1311 is used for inserting into the insertion slot. The deformation part 1312 is used for elastic deformation. The clamping part 1313 is used for clamping and fixing the line. The guide part 1314 is used for guiding the line to facilitate the line to be smoothly clamped into the clamping channel 01 between the first part 131 and the second part 132.

[0044] In actual application, the phase sequence board 100 needs to be operated by a special operating rod. Since the operating rod has a relatively long length, it is not easy to align the clamping member 13 of the phase sequence board 100 with the line. The guide slot is arranged in the guide part 1314 and communicates with the clamping channel 01. The width of the guide slot gradually increases from one end of the clamping channel 01 to the other end along the guide slot, so as to facilitate the line to enter the guide slot. When the line enters the guide slot, the line can slide into the clamping channel 01 along the guide slot. Through the above design, the phase sequence board 100 can be accurately and quickly fixed to the line.

[0045] In some embodiments, Figure 4 、 Figure 5 As shown in the figure, the extension direction of the insertion slot 02 and the side of the communication member 12 close to the first part 131 are at an inclined angle. Through the above design, when the clamping member 13 is clamped on the circuit, the first part 131 and the second part 132 will exist elastic stress between the communication member 12, the first part 131 and the second part 132 are inserted at an inclined angle, and the first part 131 and the second part 132 are inserted more firmly under the action of the elastic stress and are not easy to fall off.

[0046] As shown in the figure, Figure 1 、 Figure 2 、 Figure 3 The application provides a phase sequence identification device, which comprises a chip device 200, a solar panel 300 and a plurality of phase sequence plates 100. The solar panel 300 is electrically connected with the chip device 200. The plurality of phase sequence plates 100 are electrically connected with the chip device 200. The plurality of phase sequence plates 100 are respectively provided with a first identification member 111, a second identification member 112 and a third identification member 113. The chip device 200 is used for electrically connecting with a circuit to detect the phase sequence in the circuit. A worker operates a lever to sequentially add the phase sequence plates 100 provided with the first identification member 111, the second identification member 112 and the third identification member 113 to different-phase circuits according to the phase sequence of the circuit. Through the above design, the installation process of the phase sequence plate 100 can be completed by using the lever. The worker maintains a sufficient safety distance from the circuit, and does not need to perform power-off and climbing operations, thereby greatly reducing the installation difficulty of the phase sequence plate 100 and improving the safety of the worker operation.

[0047] In some embodiments, as shown in the figure, Figure 1 、 Figure 2 、 Figure 3As shown, the phase sequence identification device further comprises a three-core wire 400, the three-core wire 400 comprises a first line 41, a second line 42 and a third line 43, the first line 41, the second line 42 and the third line 43 are all provided with distinguishing features, and the first line 41, the second line 42 and the third line 43 are respectively connected with the plurality of phase sequence cards 100 in one-to-one correspondence; wherein the distinguishing features are used to distinguish the first line 41, the second line 42 and the third line 43, and the distinguishing features can be color, pattern or shape, etc. The chip device 200 is electrically connected with the plurality of phase sequence cards 100 through the three-core wire 400. In actual application, the chip device 200 outputs the recognized phase sequence information through the three-core wire 400, and the staff connects the first line 41, the second line 42 and the third line 43 with the plurality of phase sequence cards 100 in one-to-one correspondence according to the phase sequence through the distinguishing features, so that the regular order of the first identification piece 111, the second identification piece 112 and the third identification piece 113 of the plurality of phase sequence cards 100 is consistent with the phase sequence of the line, and then the plurality of phase sequence cards 100 are clamped on the line of the corresponding phase through the operating lever. Through the above process, the staff can accurately know the phase sequence in the line by observing the regularity of the phase sequence card 100.
