Network computer room ground network production method   First, the production of standard grounding grid At a distance of 1.5~3.0m from the building, taking the 6m*3m rectangular frame line as the center, excavate a soil ditch with a width of 0.8m and a depth of 0.6~0.8m. *50*50) Galvanized angle steel, drive one vertically at each intersection point at the bottom of the trench, a total of 6-20, as a vertical grounding electrode; Then use No. 4 (4*40) galvanized flat steel to weld and connect the six angle steels as a horizontal ground electrode; then use No. 4 galvanized flat steel to weld in the middle of the ground grid frame, and lead out to the outer corner of the computer room, high above the ground 0.3m, as the PE grounding terminal; finally, lead out a sheath ground wire of 16-50 square millimeters or more from the grounding terminal, enter the room through the wall along the wall, and connect to the equipotential grounding collection bar in the equipment room. Second，Use building steel bars as ground mesh When building or renovating a machine room, the steel bars in the concrete columns can be used as grounding devices. Select at least 4 main reinforcement bars (diagonal or symmetrical reinforcement bars) in the column, and then weld them on two copper threaded pipes above M12 extending out of the cylinder as the grounding terminal. The grounding bus bar is connected, and the equipotential grounding bar can be set under the anti-static floor.
