Embodiment Construction
[0034] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0035] A method for multi-channel rapid corrosion detection and planar imaging diagnosis of large grounding grids, such as image 3 shown, including the following steps:
[0036] Step 1. Based on the substation grounding grid construction drawings, establish the original structure topology of the grounding grid, clarify and mark the measurable points and ground structure.
[0037] In this step, relying on Microsoft VBA and GDI technology, according to the substation grounding grid drawing and the grounding leads of the actual operating equipment on site, the grounding grid is equivalent to a multi-port pure resistance network, and the actual grounding grid is converted into a computer host identification. Circuit parameters such as nodes and branch resistances form an original topology map that can be recognized by the computer host.
[0038] Step 2. Import...
