Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of ground wire clamping, in particular to a pneumatic telescopic high-altitude ground wire automatic clamping device. BACKGROUND

[0002] The ground wire is an important tool for ensuring the safety of workers when unexpected voltage appears on the already powered-off equipment and line in the power system, and its function is to prevent the sudden power supply of the equipment or the induced voltage of the adjacent high-voltage live equipment from harming the human body when the high-voltage equipment is powered off for maintenance or other work, and to discharge the residual charge of the powered-off equipment. Installing and removing the temporary ground wire is an important safety measure in the power system. At present, short-circuit ground wire is usually used in the maintenance work of the power transformation equipment, and the insulating operating rod is used to hang it on the wire.

[0003] At present, there are many problems in the power-off maintenance or other work of 500kV open-type extra-high voltage equipment and 1000kV ultra-high voltage equipment:

[0004] 1. When the equipment is maintained, due to the large safety distance of the equipment and the high installation height of the equipment, it is often difficult to achieve the manual hanging of the ground wire by using the insulating rod;

[0005] 2. The length of the conventional ground operating rod is relatively difficult to use in this working environment, and the weight of the ground wire is large, and when the ground rod is too long, there is a risk of high-altitude falling and induced electric shock when manually hanging the wire;

[0006] 3. When the boom truck is used, due to the wide distribution range of the substation, the boom truck needs to arrive at the substation site one day in advance for each power-off maintenance, and due to the high-altitude operation of the special vehicle, the driver, the boom truck operator, the special operation commander and other personnel are required to be equipped, so that the ground wire installation work can be carried out, the whole process takes a long time, which wastes a lot of time for emergency repair and maintenance work.
