The invention discloses a temporary grounding device for electric power, which includes an anti-off-type grounding buckle arranged on the ground and a grounding ring arranged on the equipment to be grounded. The anti-off-type grounding buckle includes a grounding pile body and a Grounding buckle body, the grounding buckle body is in the shape of a rectangular frame, and the right side of the grounding buckle body is provided with a connection port, the grounding ring enters the grounding buckle body through the connection port, and a closing component is arranged on the left inner wall of the grounding buckle body. Facing the connection port, after the grounding ring enters the grounding buckle body, the closing component blocks the connection port so that the grounding ring cannot be separated from the anti-drop grounding buckle. The grounding buckle body is in the shape of a rectangular frame, and the grounding ring enters the grounding buckle from the connecting port After the body, the closing component blocks the connection port, so that the anti-off-type grounding buckle forms a closed ring structure, thereby forming a fully enclosed grounding structure. After the connection, the grounding ring cannot fall off from the anti-off-type grounding buckle, so that the grounding Stability and reliability are guaranteed.
Description
Technical field [0001] The invention relates to the technical field of grounding equipment, in particular to a temporary grounding device for electric power. Background technique [0002] Grounding is a relatively low impedance path for current to return to its source. Specifically, it provides a low-impedance path for fault current to flow back to the power source when a ground fault occurs in a line or electrical equipment. The main purpose of grounding is to conduct current so that it can travel back and forth between the earth or equivalent metal conductors. It belongs to the category of conductive connection and can be divided into permanent grounding and temporary grounding. The grounding in the power system specifically refers to the reliable connection of the metal parts of various electrical equipment to the grounding electrode through the grounding wire. In most cases, it refers to the connection of the neutral point to the earth. In addition to effectively preventing ...
