Description
Technical Field
The invention relates to the technical field of electric power operation tools, in particular to a power transmission line grounding wire clamp which can be positioned and is convenient to install and disassemble.
Background
In order to ensure the personal safety of constructors for power failure maintenance lines, grounding wires are required to be hung at each end of a working section and branch wires which are possible to transmit power to power failure lines, 500kV power transmission lines are hung on grounding lines and are usually in a throwing-hanging type, the grounding wires comprise grounding ends, insulating ropes, grounding wires and wire clamps, operating personnel need to climb to a cross arm outlet, the opened wire clamps are lifted up and put down by the insulating ropes, the wires are impacted by gravity to fasten the wires, the insulating ropes are pulled forcefully when the wires are taken down, and the wires are separated from the wire clamps.
Although this method is commonly used, it has several disadvantages: firstly, when the wire clamp is taken out, the wire is pulled to break away from the clamped clamp by pulling the upward force of the insulating rope, if the wire clamp is clamped particularly tightly or the force for lifting the insulating rope upwards is not large enough, the embarrassing situation that the wire cannot break away is often caused, and the wire can only break away from the wire clamp by repeatedly pulling the insulating rope with larger force; secondly, the wire clamp taking mode inevitably causes the back-and-forth friction of the wire on the surface of the wire clamp, certain damage to the wire is caused, and a new defect is caused; the ground wire or the personal security wire is frequently missed, the lines are long due to 500kV and above, the lines are often operated at multiple points at the same time, the number of the ground wires or the personal security wires needing to be hung is large, the hanging position is very high from the ground, the lines cannot be missed easily by carefully looking, once the lines are missed, the whole line distance is too long, the lines cannot be searched easily, and finally the lines can be failed in grounding in the power transmission process and cannot transmit power. Therefore, the existing grounding wire clamp has the defects of difficult operation, low safety, difficult management and control and the like.
