Problems solved by technology
Because it is necessary to wear insulating gloves when grounding, it is very inconvenient to rotate. Usually, it takes about 20-30 minutes for unskilled staff to ground a phase, which greatly wastes power failure time and staff physical strength
It is extremely laborious to rotate when wearing insulating gloves for grounding, which also makes the operation of grounding without insulating gloves often happen

The invention discloses a novel grounding wire clamp. The novel grounding wire clamp comprises a wire clamp shell, upper column teeth, a fixed guide rail, lower column teeth, a concentric bearing, a spring, a grounding wire connection terminal, an inner wire clamp and a fixed wire clamp, wherein the upper column teeth and the lower column teeth are engaged and connected by a ratchet and are arranged at top ends of the wire clamp shell, the fixed guide rail is arranged at an inner side of the top end of the wire clamp shell, bottom ends of the lower column teeth are connected with a top end ofthe spring, a top end of the concentric bearing penetrates through the spring and the lower column teeth, a bottom end of the concentric bearing is connected with the inner wire clamp, the fixed wireclamp is arranged at a bottom end of the wire clamp shell and is opposite to a vertical surface of the inner wire clamp, and the grounding wire connection terminal is arranged on a side surface of thewire clamp shell.
Description
technical field [0001] The invention relates to the field of maintenance of power transmission and transformation lines, and more specifically relates to a novel grounding clamp. Background technique [0002] In the process of power outage inspection and maintenance of the current transmission line, the working procedures of power outage-electricity inspection-grounding are followed, and the most time-consuming and labor-intensive process is the grounding process. The traditional grounding clamp is a rotating type. By rotating the grounding rod, the clamp Tighten it tightly to the wire, so as to achieve the purpose of grounding by connecting the tower with the grounding wire. In actual work, the staff usually opens the clamp to a large extent on the tower, and then bends over or lifts up to rotate the grounding rod. Because it is necessary to wear insulating gloves when grounding, it is very inconvenient to rotate. Usually, it takes about 20-30 minutes for unskilled staff t...
