Problems solved by technology
When climbing a pole, it is necessary to drag a heavy grounding link to climb, which consumes a lot of physical strength of the workers and has a high risk factor; and it takes about 1 hour to complete the installation and removal of the grounding wire, which is time-consuming and laborious. Speed has a big impact

The invention discloses a climbing-free grounding box, which belongs to the technical field of power systems. The free-climbing grounding box includes a cable winding device and a lifting assembly. The cable winding device includes a winding mechanism and a connecting cable wound around the winding mechanism. One end of the connecting cable is connected to the overhead line, and the other A grounding joint is installed at one end; the cable winding device is arranged on the lifting assembly for adjusting the height of the cable winding device; the grounding joint is configured to be plugged with a grounding cable for conduction. Just use the lifting component to lower the cable winding device, connect the connecting cable and the grounding cable through the grounding joint, so as to ground the overhead line, reduce the risk factor of grounding, shorten the installation and removal time, and increase the speed of construction and maintenance; and After the operation is completed, the connecting cable on the cable winding device can be raised back to a high place through the lifting component, so as to avoid electric shock when passers-by pass by and improve safety.
Description
technical field [0001] The invention relates to the technical field of power systems, in particular to a free-standing grounding box. Background technique [0002] Live work is an important means and method for power grid equipment inspection, maintenance and renovation, and an important technical measure to ensure the reliable and stable operation of the power system. [0003] At present, when overhauling the power grid, the power supply system is generally turned off, and then the power personnel carry out high-altitude work. Due to the phenomenon of reverse power supply on the power grid, even if the power supply system is turned off, the power grid may still be charged. Safe operation requirements: This part of the current needs to be led to the ground, so the importance of grounding is self-evident. [0004] At present, when the overhead line is grounded, it is necessary to climb up the pole and hang the ground wire to ground the line. The grounding point is generally...
