Problems solved by technology
[0003] However, there are great problems in the use of the existing large-scale grounding grid grounding impedance detection device. The existing large-scale grounding grid grounding impedance detection device requires operators to enter the grounding grid area, which makes the operator work in a dangerous area. It is easy to cause danger to the operator, thereby reducing the safety of the device. The existing large-scale grounding impedance detection device does not drill holes before piling, which makes piling more difficult and easily causes current electrodes and voltage electrodes. damage, thereby shortening the service life. The existing large-scale grounding grid grounding impedance detection device cannot move freely, which reduces the flexibility of use. At the same time, in the process of inserting into the ground, the insertion depth cannot be accurately controlled, which reduces the detection accuracy
