Tight handle is column, and top is provided with the Handheld Division for being used for rotating clamping lever, and bottom outer wall is provided with screw thread, and lower end connects with ground connection
Connect end rotatably to fix, a supporting nut is cased with the screw thread at grounding connection end；
Grounding connection end is arranged in the space between two blocks of steel plates of steel body, and the bottom of downlead connection end passes through
One hole of the first steel plate, top protrusion steel body；Another hole for being thread through the first steel plate of clamping lever bottom, on
Steel body is protruded in portion, and nut is located at the top of the first steel plate.
Preferably, the top of downlead connection end is provided with a square termination, and the hole of lateral direction penetrating is provided with termination.
Compared with prior art, temporary grounding end device provided by the utility model can quickly, be fixedly secured once
On all kinds of down conductors of equipment, while the earth terminal to match with the ground wire of each transformer station's configuration at present is also equipped with, so as to
Meet the needs of any position needs mount ground wire temporarily in the scope of repair, specification is provided for various forms of equipment ground lines
The transition apparatus of change.
The main body of temporary grounding end device of the present utility model is steel design, and reliability is high, connection end and conductive bodies
It is reliability and durability.At present, device of the present utility model is successfully tried out, working specification, quick, great popularization.
Brief description of the drawings
Fig. 1 is the structural representation of temporary grounding end device of the present utility model.
Fig. 2 is the side view of steel body.
Embodiment
Below in conjunction with the accompanying drawings and specific embodiment is described further to the utility model, but following embodiments are right absolutely not
The utility model has any restrictions.
As shown in Figure 1-2, the temporary grounding end device includes：Downlead connection end 1, steel body 2, grounding connection end 3,
Clamping lever 4 and nut 5.
Wherein, steel body 2 includes about two pieces the first steel plates 21 and the second steel plate 22 be arrangeding in parallel, same by one piece
When be connected to the connecting plates of two pieces of steel plate ipsilateral penumbras and be connected, the plane of the first steel plate 21 is provided with two holes；
Grounding connection end 3 is copper plate, and the lower end of the downlead connection end 1 of column is fixed on the surface at grounding connection end 3；
Clamping lever 4 is column, and top is provided with the Handheld Division for being used for rotating clamping lever 4, and bottom outer wall is provided with screw thread, and lower end is with connecing
Ground connection end 3 is rotatably fixed, and a supporting nut 5 is cased with the screw thread at grounding connection end 3；
Grounding connection end 3 is arranged in the space between two blocks of steel plates of steel body 2, the bottom of downlead connection end 1
Through a hole of the first steel plate 21, top protrusion steel body 2；The bottom of clamping lever 4 is thread through first steel plate 21
Another hole, top protrusion steel body 2, nut 5 are located at the top of the first steel plate 21.
The top of downlead connection end 1 is provided with a square termination, and the hole of lateral direction penetrating is provided with termination.
When using temporary grounding end device of the present utility model, first by staff by various shapes in substation equipment
The down conductor of formula is connected on downlead connection end 1, such as down conductor can be clipped in into downlead using crocodile clip
