AI Technical Summary
The ground resistance test of existing substation ground grid is very prone to rust, manual hammering is laborious and difficult to grasp, the depth of entry is limited, the connection method is unstable, which affects the accuracy of the test and may lead to dangerous accidents.
A test pole including a test pole body, a ground spiral, a ground screw and a grounding seat was designed. The combined structure of a ground spiral and a grounding screw is used to drive the test pole to rotate into the ground through a manual power tool, and the clamping connection between the ground wire clamp and the grounding rod is used to ensure the stable connection of the test line.
The test pole is successfully entered into the hard soil surface to more than 20cm, reducing labor labor and rust problems, improving testing accuracy and safety, simplifying the operation process, and saving time and labor.
