Technical Field
[0001] The utility model belongs to the technical field of power equipment, and particularly relates to a grounding device for a power system. Background Art
[0002] A grounding wire is a wire directly connected to the earth, which can also be called a safety return wire. In case of danger, it directly transfers high voltage to the earth. It is a life-saving wire. Currently, in the grid operation of the power system, grounding wires need to be installed to ensure the safety of operators. The grounding wire is a safety barrier for protecting operators and a life-saving wire for them, which can prevent sudden power-on from hurting people. When using the existing grounding wire dismounting and mounting device, the operator needs to hang the grounding rod on the grounding point at a high place of a conductor such as a wire, and then lead the grounding wire connected to the grounding rod into the ground through a grounding flat iron. Since the heights of conductors such as wires are different, it is quite laborious to hang them, and the storage of the grounding wire after use is also inconvenient. Moreover, since the dismounting and mounting device does not have an auxiliary pressing and fixing structure, the grounding rod needs to be pressed and held by the operator, and the operation is also quite laborious. If the operator violates the regulations and does not perform voltage testing, accidents will occur.
[0003] In view of the above problems, the Chinese utility model patent with the application number CN202221255670.4 discloses a convenient-to-use grounding wire dismounting and mounting device for a power system substation. The convenient-to-use grounding wire dismounting and mounting device for a power system substation includes a moving base; a placing box is fixedly installed on the moving base. A storage groove, a storage slot and a winding slot are successively formed inside the placing box. The storage groove can store the grounding rod with a detachable structure, the storage slot can store the grounding rod, and a winding structure capable of winding the grounding wire is arranged in the winding slot; an auxiliary structure is also fixedly installed on the moving base on the side of the placing box away from the trolley handle. The above device adopts a grounding rod with a detachable structure, and its length can be assembled according to the height of the wire, which is convenient for power maintenance personnel to hang, improves safety, and is also convenient for storage; at the same time, the winding roller can wind the wire, improving convenience and saving the dismounting and mounting operation time; in addition, the auxiliary structure can push the grounding rod to be inserted into the ground, further improving the convenience when using the dismounting and mounting device.

[0041] Usage method:
[0042] Preparation before installation: All components and auxiliary tools of this device are usually stored in the storage box 400 uniformly, and the storage box 400 is stored in a fixed room. When it is necessary to hang the grounding wire, push the storage box 400 from the installation room to the equipment site, brake the foot brake of the second roller 407, open the storage box 400, and take out the wiring clip head 100, grounding wire set 200, insulating rod 300, and wire reel 500 in sequence.
[0043] Install the grounding wire: Pull down the insulating joint 106 of the wiring clip head 100, drive the lower jaw piece 104 of the wiring clip towards the fixed piece 101 through the metal rod 107, and compress and store energy in the first spring 105. When the thread of the metal rod 107 contacts the middle screw hole of the fixed piece 101, rotate the insulating joint 106 clockwise to make the thread of the metal rod 107 fit into the middle screw hole of the fixed piece 101, and then rotate a certain number of turns as needed to make the opening distance between the upper and lower jaw pieces 104 meet the requirements, and safely maintain the first spring 105 in the energy storage state, as Figure 6 shown. Connect the insulating joint 106 of the wiring clip 100 after energy storage to the assembled insulating rod 300 through the spring buckle 302. Pull out the grounding wire set 200 from the wire reel 500, and fixedly connect the main wiring to the grounding stake.
