Description

Technical Field

[0001] The invention relates to the technical field of grounding wire clamping, and in particular to a pneumatic telescopic high-altitude grounding wire automatic clamping device. Background Art

[0002] The grounding wire is an important tool in the power system to ensure the safety of workers when voltage unexpectedly appears on the power-off equipment and lines. Its function is to prevent the equipment from suddenly receiving power or the induced voltage generated by the adjacent high-voltage live equipment from causing harm to the human body when the high-voltage equipment is powered off for maintenance or other work, and to discharge the residual charge of the power-off equipment. The installation and removal of temporary grounding wires is an important safety measure in the power system. At present, short-circuit grounding wires are usually used in the maintenance of substation equipment, and they are hung on the wires using insulated operating rods.

[0003] At present, there are many problems when performing power outage maintenance or other work on 500kV open-type ultra-high voltage equipment and 1000kV ultra-high voltage equipment:

[0004] 1. When equipment maintenance is required, it is often difficult to manually hang the ground wire with an insulating rod due to the large safety distance of the equipment and the high installation height of the equipment;

[0005] 2. The length of the conventional grounding operating rod is relatively difficult to use in this working environment. At the same time, the grounding wire is heavy. If the grounding rod is too long and relies on manual hanging, there is a risk of falling from a height and the risk of inductive electric shock;

[0006] 3. When using a boom truck, due to the wide distribution of substations, each power outage and maintenance requires the boom truck to arrive at the substation site one day in advance. At the same time, since it involves high-altitude operations of special vehicles, it is necessary to be equipped with a driver, boom truck operator, special operations commander, etc. before the grounding wire installation work can be carried out. The whole process takes a long time, which wastes a lot of time for emergency repairs and maintenance work. The large size of the boom truck invisibly increases the risk factor on site, as well as the difficulty of management and control, and increases the risk of equipment damage, induced electric shock and falling from heights.
