Abstract
The utility model relates to a grounding copper ring for 10 KV cables and distribution transformers. The utility model is characterized in that: the copper ring is composed of a straight bar and a ring made of a copper tube; an iron core is arranged in the copper ring; an insulating sheath is positioned outside the copper ring; the head of the straight bar of the copper ring is connected to a terminal; the terminal is connected to the lower end of the dropping fuse of a 10 KV cable or a 10 KV distribution transformer, one end of the copper ring is provided with an electricity-testing grounding tube. With the copper ring made of the copper tube, the technical proposal has the advantages of good conductivity with the iron core in the copper ring, guaranteed strength with the insulating sheath outside the copper ring and safe usage. Particularly with the copper ring connected to the lower end of the dropping fuse of the 10 KV cables or the 10 KV distribution transformers, the electricity is first tested at the tube during the operation and then the grounding wire is connected to ensure a safe operation.
Description
Technical field
The utility model relates to 10KV cable, distribution transformer ground connection copper ring, is used for the electrical verification of falling the fuse lower end or the hanging wire ground connection of 10KV cable and 10KV distribution transformer.
Background technology
When 10KV high-tension cable and the operation of 10KV distribution transformer, need cut off the electricity supply, after cutting off the electricity supply, prior art do not carry out electrical verification (electric current and voltage test), there is not earth point yet, so be dangerous operation, exist the hidden danger of personal safety.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of prior art, when a kind of 10KV cable, distribution transformer operation are provided, but can conveniently carry out electrical verification and hanging earthing conductor, guarantees safe 10KV cable, distribution transformer ground connection copper ring.
The technical scheme of the utility model 10KV cable, distribution transformer ground connection copper ring is: it is characterized in that one is made annular and the copper ring formed of straight-bar by copper pipe, iron core is installed in copper ring, copper ring has insulating sleeve outward, straight-bar head at copper ring is connected with terminal, terminal links to each other with the fuse lower end of falling of 10KV cable or 10KV distribution transformer, has ground connection to reveal pipe in an end of copper ring.The technical program copper pipe is made copper ring, conducts electricity very well, and is cored in copper ring, intensity guarantees, insulating sleeve is arranged, the made sheath of silastic material for example, good pressure-resistant performance outside copper ring, safe in utilization, such copper ring has particularly been arranged, and what be connected 10KV cable or 10KV distribution transformer falls the fuse lower end, at first carries out electrical verification revealing the pipe place during operation, hang up earth connection again, guarantee job safety.
Description of drawings
Fig. 1 is the utility model 10KV cable, distribution transformer ground connection copper ring structural representation.
Embodiment
The utility model relates to 10KV cable, distribution transformer ground connection copper ring, as shown in Figure 1, its major technology is characterised in that one is made annular 11 and the copper ring formed of straight-bar 12 by copper pipe, iron core 2 is installed in copper ring 1, insulating sleeve 3 is arranged outside the copper ring 1, straight-bar head at copper ring is connected with terminal 4, and terminal 4 links to each other with the fuse lower end of falling of 10KV cable or 10KV distribution transformer, has ground connection to reveal pipe 5 in an end of copper ring.Its described insulating sleeve is that silastic material is made.This product adds man-hour; round steel (as iron core) can be inserted in the copper pipe; annular 11 is made in a bending; straight-bar 12 is reserved in the other end; at the head of the straight-bar 12 copper sleeve-terminal 4 of burn-oning; wrap insulating sleeve 3 in the outside of copper ring 1 again, sheath material is good with silastic material, crust protection proof voltage 10KV.But expose the dew pipe 5 that one section copper pipe does not have insulation, copper ring 1 terminal of making 4 is connected the 10KV cable or the 10KV distribution transformer falls fuse bottom (the permanent connection), after cutting off the electricity supply during operation, revealing pipe 5 places electrical verification, really after not having electric current, hang up earth connection, operation finishes, and takes down earth connection.
Claims (2)
1,10KV cable, distribution transformer ground connection copper ring, it is characterized in that one is made annular and the copper ring formed of straight-bar by copper pipe, iron core (2) is installed in copper ring (1), insulating sleeve (3) is arranged outside the copper ring (1), straight-bar head at copper ring is connected with terminal (4), terminal (4) links to each other with the fuse lower end of falling of 10KV cable or 10KV distribution transformer, has ground connection to reveal pipe (5) in an end of copper ring.
