FIELD: electric power engineering, applicable for temporary grounding of movable and other installations. ^ SUBSTANCE: the portable grounding connection has a base with electrodes that carries a mechanism for manual submersion of two inclined grounding electrodes at an angle of 45 deg. to the ground and symmetrically at an angle of 90 deg. to each other, as well as for dismantly of the grounding connection. The connection is assembled with the aid of a leverage system installed on a base for adjustment of the force of pressing-in of the grounding electrodes. The connection provides for submersion of the grounding electrodes into the damp layers of the ground, reduction of the resistance to spreading of current in the ground, and maintenance of the stable value of the resistance of the grounding connection at variation of the ground dampness. ^ EFFECT: reduced labor content, excluded earth-moving operations and reduced area of earth required for the grounding connection. ^ 2 dwg |
