With the continuous development of power systems, the need for grounding is getting higher and higher. So, how to choose a suitable grounding material? Copper braid has always been the grounding material of choice.
Since the cost of copper is higher than that of steel, choosing copper grounding grid design often increases the project investment of the substation. After fully studying the characteristics of copper, the following methods can be used to reduce grounding grid investment. :
In order to reduce the number of horizontal lap welding points, the horizontal grounding body is made of rolled copper stranded wire, which is also easy to transport. Considering the beauty of the substation, copper bars are selected for the equipment down conductors.
Deepen the design depth, appropriately reduce welding points, and control investment.
If a copper grounding grid is used, the cross-section of the equipment down-lead is only 1, and the cross-section of the horizontal grounding body is only 1. If a galvanized flat steel grounding grid is used, the cross-section of the grounding body is greatly reduced.
Choose a grounding grid designed with galvanized flat steel. Considering that flat steel will corrode and rust, it is necessary to ensure reliable grounding. After selecting a copper grounding grid, the corrosion of the grounding down conductor can be ignored, so a single grounding down conductor can be selected.
Compared with hot-dip galvanized steel grounding materials, copper grounding materials have great advantages in conductive performance, corrosion resistance and construction convenience. Because copper wires are flexible and have a small allowable bending radius, they are easy to bend and easy to thread. Copper conductors have high mechanical strength and can be supplied in rolls, which facilitates mechanized construction. Due to the use of exothermic welding, the operation is convenient, the construction progress is accelerated, labor costs are saved, and the construction process is simplified. More importantly, the connection quality of the copper grounding network is ensured. There are two main methods of corrosion of grounding bodies: chemical corrosion and electrochemical corrosion. In most cases, these two types of corrosion exist together. The corrosion rate of the grounding body underground is affected by the resistivity, moisture content, oxygen content, pH, electrolyte, stray current and soil compaction of the soil.
