Abstract

The invention discloses a grounding grid, and belongs to the technical field of electrical application. The grounding grid comprises a backbone network, and at least one group of grounding electrodes. Each group of electrodes comprises at least one grounding electrode. At least one group of grounding electrodes are connected with different positions of the backbone network respectively under the backbone network. The backbone network is positioned under the buildings, and is insulated from the peripheral soils. The grounding grid discharges through the grounding electrodes. The backbone network is provided with at least one connection point, which is used for the connection with the electrical equipment. Each electrode of at least one group of electrodes is positioned in the grounding well. Through the placement of at least one group of electrodes under the backbone network, and through the placement of each electrode of at least one group of electrodes in the grounding well, and through the insulation of the backbone network from the peripheral soils, the grounding grid can only discharge through the grounding electrodes in the grounding well, which means the discharging happens in the deep underground, thus avoiding the creation of step voltage on the ground, bringing no hazards to the pedestrians, and enhancing the safety of the grounding grid.

Description

technical field [0001] The invention relates to the electrical field, in particular to a grounding grid. Background technique [0002] In daily life, whether it is electrical equipment or above-ground buildings, it is necessary to drain the current to the ground through the grounding grid, so as to complete the discharge, so as to protect the safety of equipment and personal safety. [0003] In the prior art, a grate-shaped metal grid is usually used as a grounding grid and placed 0.8 meters underground in the building, and a connection point is set on the metal grid to connect with the equipment in the building, and a vertical grounding body is set on the metal grid , so that the current of the equipment in the building is led to the vertical grounding body through the metal grid, and the current is released to the ground and deep underground through the metal grid and the vertical grounding body. The voltage between the pedestrian's two feet), thus completing the discharg...
