Abstract
The invention provides a ground rod for a power supply line. The ground rod comprises an operation rod, a hooking piece, a meshing plate and a grounded annealed copper wire, wherein the operation rod comprises an insulating rod body and a screw, and a connecting terminal is arranged at one end of the grounded annealed copper wire. The ground rod is structurally characterized by further comprising a protective spring, the hooking piece comprises a hooking plate and an operating rod connecting plate, the hooking plate and the operating rod connecting plate are integrally connected, the screw of the operating rod penetrates through the operating rod connecting plate from bottom to top and extends upwards, an arc-shaped meshing port concave downwards is formed in the upper end of the meshing plate, the lower end face of the meshing plate is fixedly connected with the upper end of the screw of the operating rod, the grounded annealed copper wire is in bolted connection with the hooking plate of the hooking piece through the connecting terminal of the grounded annealed copper wire, the protective spring is connected to the side, provided with the connecting terminal, of the grounded annealed copper wire in a sleeving mode, and one end of the protective spring is fixedly connected with the connecting terminal of the grounded annealed copper wire. By the adoption of the ground rod, the strand breaking rate of the grounded annealed copper wire can be effectively reduced, the effect that short-circuit current is grounded through the ground rod is guaranteed, and the service life of the ground rod is prolonged.
