(I) Characteristics of underwater grounding grid of floating photovoltaic power station
1. No need to dig underwater, easy construction, and reduced construction cost. 2. Water is corrosive, and corrosion-resistant grounding materials are required. 3. The water area is large, water can conduct electricity, and its own grounding resistance is stable.
(II) Selection of grounding materials for floating photovoltaic power station
1. Because the water area is large and water can conduct electricity, floating photovoltaic does not require vertical grounding, as long as the horizontal grounding wire is laid on the bottom of the water. 2. The horizontal grounding wire should be in the form of twisted wire, with fewer joints, corrosion resistance, easy bending, convenient construction, and reduced cost. 3. The horizontal grounding wire can be physically connected (clip connection) and chemically connected (exothermic welding)
(III) Construction precautions for floating photovoltaic power station
1. Connection between photovoltaic panels: use
yellow-green grounding wire BVR 4mm2. 2. Connection between photovoltaic brackets: use yellow-green grounding wire BVR 16mm2.
(IV) Application areas of water photovoltaic power stations
Ponds, rice fields, small lakes, reservoirs, water storage tanks, mines, etc.
