Inner face is made more to fit with ground wire operating lever 2, to increase the contact area of semilune pad 32 and ground wire operating lever 2.This
Sample, can apply bigger frictional force by semilune pad 32 earth wire action bars 2 when wing nut 33 is locked, thus tightly
Gu adaptor 1 and ground wire operating lever 2.Owing to the external diameter of the ground wire operating lever 2 of different manufacturers is different, therefore by the present embodiment
In the interior curvature radius of semilune pad 32 take 12mm ~ 15mm, i.e. slightly larger than the maximum outside diameter of ground wire operating lever 2.Pad
Circular hole aperture in the middle part of sheet is 3mm ~ 6mm, it is ensured that pad circular hole, the circular hole 121 of adaptor 1 plug, ground wire operating lever 2 are even
Aperture between the parts such as groove, double threaded screw 31 and wing nut 33 on joint chair good fit.
In the specific implementation, ground wire operating lever is connected on adaptor plug the present embodiment, and earth lead passes through earth lead
Folder is connected on adaptor socket, and ground wire operating lever rotarily drives adaptor and rotates, and then drives earthing clamp to rotate, with dress
If or remove earth lead, it is possible to use the adaptor 1 earth lead 5 to mating and ground connection action bars 2 are transferred.Electrical network is looked forward to
Without considering further that the matching problem of earth lead and action bars when electric-power safe instruments is managed by industry, simplify Unit account of plant and set
Standby buying, allocation process, reduce management difficulty.Simultaneously, it is not necessary to high-volume change existing ground wire and action bars, therefore, it is possible to
Cost-effective, it is to avoid the waste to existing assets.
The present embodiment is for the adaptor 1 of the switching device of ground wire operating lever, and whole height is about 80mm, maximum outside diameter
Less than 40mm, overall weight is less than 100g.There is volume advantage little, lightweight, portable.In actual electric operation,
Operator can carry with, and takes at any time when needing, and extra work will be caused to bear it.
Implement the switching device for ground wire operating lever of the present invention, there is following beneficial effect:
The first, ground wire operating lever is connected on adaptor plug, and earth lead is connected on adaptor socket by earthing clamp,
Ground wire operating lever rotarily drives adaptor and rotates, and then drives earthing clamp to rotate, with installing or dismounting earth lead.This structure
The installing that can make earth lead is no longer limited by certain certain types of action bars, the favourable pipe simplifying power system security Work tool
Reason, the problem effectively solving earthing clamp and action bars cause diversified in specifications, reduces power grid enterprises' managing security tools and instruments management difficulty.
The second, assembling connecting piece includes the double threaded screw that is connected on ground connection action bars and in order to be connected to switching
Semilune pad on head plug and for compressing the wing nut of semilune pad, adaptor is capable of with ground connection action bars
