Abstract
A needle-type low-voltage protection grounding wire comprises a needle-type clamp, a grounding wire body and a ground clamp, the needle-type clamp is connected with the ground clamp, and the grounding wire body is connected with the ground clamp. The needle-type clamp comprises a column with a hook structure on the head portion, a needle-type threaded rod, a framework with a threaded hole and a rotary handle, wherein the middle of the column with the hook structure on the head portion is fixedly connected with the framework with the threaded hole, the needle-type threaded rod penetrates through the framework with the threaded hole and is in threaded connection with the framework with the threaded hole, the pointed portion of the upper end of the needle-type threaded rod corresponds to the inner side of a hook of the column with the hook structure on the head portion, and the rotary handle is perpendicularly connected with the lower end of the needle-type threaded rod. The grounding wire has the advantages that the safety hidden risk of inverse power transmission endangering human and equipment safety occurring when a power generator of a user, a solar power generation device and other user devices are powered off is overcome, the problem that an insulated wire and a cable cannot be connected with the grounding wire is solved and safety and reliability of the grounding wire during power-off operations are improved.
