Description

GRID TYPE OF GROUND PLATE

The present invention relates to a ground plate, and more particularly, to a grid-type ground plate.

As a grounding configuration used in various electrical installations or communication equipment, bare copper wires and grounding plates are now widely used.

The main use is a bare copper wire, which is used to form a grounding network. However, since the outer diameter of the bare copper wire is small, there is a problem in that the contact area with the ground is reduced, and thus the ground resistance value cannot be obtained as desired. In order to obtain a desired grounding resistance value, the amount of bare copper wire required is inevitably increased, and the construction becomes difficult and the construction cost increases.

On the other hand, some devices use a grounding plate. In the case of burying the grounding plate in the ground, there is a problem in that a desired grounding resistance value cannot be obtained because the grounding plate is not in close contact with an uneven ground such as gravel or sand.

That is, in order to obtain a desired grounding resistance value, the grounding configuration and the ground must be in close contact with each other so that an actual contact surface must be wide.
