| titleOfInvention | On-line monitoring device and method for grounding resistance of grounding grid of railway traction substation |
| abstract | The invention provides an on-line monitoring device and method for grounding resistance of the grounding grid of a railway traction substation, which solves the problem that the resistance of the grounding grid cannot be tested after the traction substation is put into operation. The railway traction substation includes a centralized grounding box, the grounding grid is connected to the centralized grounding box, and the centralized grounding box is provided with a grounding busbar; the grounding resistance online monitoring device of the grounding grid of the railway traction substation includes: monitoring terminal, current transformer and grounding The monitoring terminal is set in the centralized grounding box, the monitoring terminal is connected to the grounding busbar, the monitoring terminal is connected to the grounding electrode, and the monitoring terminal measures the potential of the grounding grid; the grounding electrode is set outside the grounding grid, and the closest distance between the grounding electrode and the grounding grid is sufficient Preset distance; the current transformer is set on the grounding busbar, the secondary terminal of the current transformer is connected to the monitoring terminal, and the monitoring terminal is used to obtain the ground return component in the return current of the traction substation, and calculate the grounding grid potential and ground The ratio of the return flow obtains the ground resistance. |
