The grounding wiring of the bridge refers to the arrangement of the grounding wires of the metal bridge in the bridge system to ensure the reliable grounding of the bridge system and prevent personal electric shock or equipment damage. The specific method for grounding and wiring of Shandong bridge is as follows:
Determination of ground point: First, it is necessary to determine the ground point of the bridge system. Generally, the ground point should be close to the incoming power line, which can ensure a small ground resistance.
Layout of grounding wire: The grounding wire should be copper wire or copper bar, and the cross-sectional area of the copper wire should be determined based on the load current of the system. The grounding wire should be arranged close to the bridge to avoid passing through the middle of the bridge.
Connecting the ground wire: The ground wire should be connected using a dedicated ground clamp, which should be fastened firmly, and the surface should be clean to ensure a low ground resistance.
Measuring ground resistance: After completing the grounding wiring, it is necessary to use a multimeter or ground resistance tester to conduct a ground resistance test to ensure that the ground resistance meets the requirements. The ground resistance should be less than the specified value.
Periodic inspection: After completing the grounding wiring, it is necessary to conduct regular inspections to ensure the reliability of the grounding system. Especially after the bridge system is modified or repaired, it is necessary to recheck the grounding resistance of the grounding system.
In summary, the grounding wiring of the bridge is an important measure to ensure the safe and reliable operation of the bridge system, and careful arrangement and inspection are required to ensure that the grounding resistance meets the requirements.
