Example Embodiment

[0015] The present invention will be further described below in conjunction with the drawings and embodiments, but it is not a basis for limiting the present invention.

[0016] Examples. Auxiliary electrode structure for ground resistance measurement of large grounding grid, such as figure 1 As shown in Figure 2: It includes a center bracket 1 made of metal. The center bracket 1 is provided with a positioning hole in the center, and a center metal pile 2 is arranged in the positioning hole. The outer side of the center bracket 1 is connected with 6 evenly distributed pins 3 through 6 rotating pins. The support arms 4 made of metal are connected; the end of each support arm 4 is provided with a positioning sleeve 5, and a side metal pile 6 is provided in the positioning sleeve 5. The connection between the central support 1 and the support arm 4 is provided with a limit frame 7 that limits the maximum opening angle of the support arm 4 to less than 90° (in use, the support arm 4 is
