The sizes of the left U-shaped ring 100 and the right U-shaped ring 200 are the same, and the sizes of the plug interface 110 and the plug connector 210 match each other. The two ends of the left U-shaped ring 100 are aligned with the two ends of the right U-shaped ring 200, and the two plug connectors 210 at the ends of the right U-shaped ring 200 are respectively inserted into the two plug interfaces 110, so that the left U-shaped ring 100 and the right U-shaped ring 200 are spliced ​​into a whole to form a complete annular tube, and then a fixing unit 300 is taken, and the two plug-in rods 340 are respectively inserted into the two plug-in holes 120 on the surface of the left U-shaped ring 100, so that the fixing unit 300 and the left U-shaped ring 100 are connected in series, and then another fixing unit 300 is taken, and the two plug-in rods 340 on the fixing unit 300 are respectively plugged in and connected in series with the two plug-in holes 220 on the surface of the right U-shaped ring 200. At this time, the two fixing rings 310 are symmetrical to each other, and the inner arc surfaces of both face each other. The two fixing rings 310 are fixed on the insulator string, and the two fixing rings 310 are fixedly connected together by bolts.

[0032] like Figure 3 and Figure 7 As shown, in the present embodiment, the outer wall of the left U-shaped ring 100 near the two ends is provided with an annular groove 130, and the outer wall of the right U-shaped ring 200 near the two ends is provided with an annular groove 230, and the fixed sleeve 400 includes an upper jacket 410 and a lower jacket 420, the inner wall of the upper jacket 410 is fixedly connected with an arc-shaped fitting strip 1 411 and an arc-shaped fitting strip 2 412, and the inner wall of the lower jacket 420 is fixedly connected with an arc-shaped fitting strip 3 421 and an arc-shaped fitting strip 422, the arc-shaped fitting strip 1 411 and the arc-shaped fitting strip 3 421 are matched with the annular groove 130, and the arc-shaped fitting strip 2 412 and the arc-shaped fitting strip 4 422 are matched with the annular groove 230.

[0033] In this embodiment, the upper jacket 410 and the lower jacket 420 have the same size. After the left U-shaped ring 100 and the right U-shaped ring 200 are plugged together, the fixing sleeve 400 is taken out, and the upper jacket 410 is first buckled on the outer wall of the interface position of the left U-shaped ring 100 and the right U-shaped ring 200, so that the arc-shaped fitting strip 411 and the annular groove 130 are embedded in the annular groove 130. The arc-shaped fitting strip 2 412 is embedded in the annular groove 230, and then the lower jacket 420 is buckled at the position not covered by the upper jacket 410, so that the arc-shaped fitting strip 3 421 is embedded in the annular groove 130, and the arc-shaped fitting strip 422 is embedded in the annular groove 230. The inner arc surfaces of the upper jacket 410 and the lower jacket 420 are both fitted with the outer surfaces of the left U-shaped ring 100 and the right U-shaped ring 200, and the cross-sections of the upper jacket 410 and the lower jacket 420 are fitted together, and the upper jacket 410 and the lower jacket 420 are fixed together by welding. Then, use another fixing sleeve 400 to fix the other end joint of the left U-shaped ring 100 and the right U-shaped ring 200 according to the same operating steps as above. Due to the cooperation between the arc-shaped fitting strip 1 411, the arc-shaped fitting strip 2 412, the arc-shaped fitting strip 3 421, the arc-shaped fitting strip 422 and the annular groove 1 130 and the annular groove 2 230, and the upper jacket 410 and the lower jacket 420 are welded and fixed together, the left U-shaped ring 100 and the right U-shaped ring 200 are fixed to prevent the two from separating.

[0034] like Figure 4-6 As shown, in this embodiment, the outer walls of the four plug-in rods 340 are each provided with a contact assembly 1 350, and the contact assembly 1 350 includes a sleeve 1 351, which is slidably sleeved on the outer wall of the plug-in rod 340, and the bottom end of the sleeve 1 351 is fixedly connected with an arc-shaped gasket 1 352, and the outer walls of the four plug-in rods 340 are each provided with a contact assembly 2 360, and the contact assembly 2 360 includes a sleeve 2 361, which is slidably sleeved on the outer wall of the plug-in rod 340, and the top end of the sleeve 2 361 is fixedly connected with an arc-shaped gasket 2 362, a threaded groove 342 is provided at the bottom end of the plug-in rod 340, and a nut 370 is screwed and connected to the outer wall of the plug-in rod 340 with the threaded groove 342, and a circular hole 343 is penetrated through the outer wall of the plug-in rod 340 near the upper end, and a bolt is inserted and fixed in the circular hole 343.

[0035] In a specific implementation, before inserting the plug rod 340 into the plug hole 120 or the plug hole 220, first sleeve the sleeve 1 351 on the outer wall of the plug rod 340, and then make the plug rod 340 penetrate the plug hole 120 or the plug hole 220 from top to bottom, so that the bottom end of the plug rod 340 extends out of the outer wall of the left U-shaped ring 100 or the right U-shaped ring 200 located below, and at this time, sleeve the second sleeve 361 is sleeved on the outer wall of the end of the plug rod 340 located below the left U-shaped ring 100 or the right U-shaped ring 200, and the nut 370 is screwed with the threaded groove 342 on the plug rod 340. After screwing, the nut 370 supports the bottom end of the sleeve 2 361, and the inner arc surface of the arc gasket 2 362 is aligned with the left U-shaped ring 1 00 or the outer surface of the right U-shaped ring 200 located at the bottom is fitted, and the sleeve 1 351 is slid downward along the plug-in rod 340 to make the inner arc surface of the arc gasket 1 352 fit with the outer surface of the left U-shaped ring 100 or the right U-shaped ring 200 located at the top. At this time, the round hole 343 is exposed above the sleeve 1 351, and the bolt is inserted into it. The bolt limits the position of the sleeve 1 351, so that the arc gasket 1 352 and the arc gasket 2 362 form a clamping effect on the left U-shaped ring 100 or the right U-shaped ring 200, and the fixing unit 300 is fixed to the left U-shaped ring 100 or the right U-shaped ring 200, which is convenient for disassembly and installation, reduces the dependence on welding process, thereby simplifying the installation process and improving installation efficiency.

[0036] like Figure 4 As shown, in this embodiment, the inner arc surfaces of the two fixing rings 310 are both provided with anti-slip grooves 311, a fastening knob 1 331 is installed between the connecting column 320 and the rotating rod 330, and a fastening knob 2 344 is installed between the rotating seat 341 and the rotating rod 330.

[0037] During specific implementation, the inner arc surfaces of the two fixing rings 310 that are in contact with the insulator string for installation are both provided with anti-skid grooves 311. The anti-skid grooves 311 can increase the friction between the fixing ring 310 and the insulator string, making the connection between the fixing ring 310 and the insulator string tighter, thereby enhancing the connection strength and preventing the insulator string from sliding or falling off under the action of external forces such as wind and vibration. The two ends of the rotating rod 330 are rotatably connected to the rotating seat 341 and the connecting column 320 respectively. By installing a tightening knob 1 331 between the rotating rod 330 and the connecting column 320, and installing a tightening knob 2 344 between the rotating rod 330 and the fixing ring 310, the degree of tightening between the two can be changed by adjusting the tightening knob 1 331 or the tightening knob 2 344.

[0038] In the present invention, in order to improve the corrosion resistance and service life of the equalizing ring, a protective coating or special treatment can be added to the surface of the left U-shaped ring 100, the right U-shaped ring 200, the fixing unit 300 and the fixing sleeve 400. These coatings or treatments can protect the equalizing ring from erosion by environmental factors such as moisture, corrosion and ultraviolet rays. If it is necessary to monitor the working status or performance of the equalizing ring, monitoring sensors can also be added thereto to monitor the temperature, current and other parameters of the equalizing ring in real time, so as to promptly discover and deal with potential problems.

[0039] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
