Embodiment 1
[0047] Such as figure 1 As shown, a method for measuring the impact grounding resistance considering the temperature of the ground grid includes the following steps:
[0048] Step 1: On-site pilot research
[0049] The grounding grid is selected to be as deep as H=0.8m from the ground, and the length of the longest side of the grounding grid is L 1 is 20m, the cross-sectional area of the grounding grid S 1 25*πmm 2 The rectangular area S surrounded by the four sides of the grounding grid 2 100m 2 , lightning impulse current I m The area of 70kA is used as the test area, and the soil resistivity of this area is ρ is 150(Ω.m -1 ).
[0050] Step 2: Select the measurement point and assemble the combined experimental device
[0051] Take nine measuring points in the whole grounding grid, among which the four corners of the grounding grid are respectively selected as points 1, 2, 3, and 4; points 5 and 6 are selected at the bottom of the grounding grid; Choose 9 points....
