Information identification ring of low-voltage line

The invention discloses an information identification ring of a low-voltage line. The information identification ring comprises an identification ring body, a battery and a gravity ball state lamp. The identification ring body is of an annular structure, fixes a to-be-identified line through interference fit between the annular structure and the to-be-identified line, and is used for adhering an information label of the to-be-identified line. A sliding rail which is concavely arranged is arranged at the edge of the identification ring body. The identification ring body is composed of two semi-circular rings with the same shape, and the upper semi-circular ring of the identification ring body and the lower semi-circular ring of the identification ring body are fixed through a buckle structure. The upper semi-circular ring of the identification ring body is provided with an iron core contact point and a Hall element, and the lower semi-circular ring of the identification ring body is provided with an iron core
