Abstract
A direct fine-adjustment type electricity-testing grounding ring comprises a ring formed by a copper tube and a direct rod, wherein an insulation sheath is arranged outside the ring and the direct rod and an upper terminal is formed on the direct rod head and one end of the ring comprises a grounding exposed tube, characterized in that: an aluminum bar is inlaid in the copper tube and a hanging hole is formed in the upper terminal and the hanging hole is connected with a dropping fuse and a lower terminal is formed at the bottom of the ring and connected with a three-phase cable or a down lead of a distribution transformer. The direct fine-adjustment type electricity-testing grounding ring is used for electricity-testing grounding and connecting a whole line with the branched line or user cable and the main features are that: the aluminum bar is inlaid in the copper tube. The full conductor quality is reliable and the ring for disassembling and hanging the grounding wires good and the adjustment range is in 15 degree and the connection between the ring and the dropping fuse is convenient. If the vertical angle is not proper during installation, the angle is adjusted on the work stable (table vice) in range of 15 degree with features of simple structure and flexible use. The lower terminal is formed at the bottom of the ring for connecting 10KV three-phase cable or the down lead of the distribution transformer.
Description
Technical field
The utility model relates to and both is used for the cable connection, also makes the earthy direct fine adjustment type electricity testing grounding ring of electrical verification.
Background technology
When high-tension cable and distribution transformer operation, 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, belong to and forbid operation, relate to the problem of personal safety.The applicant had once designed a kind of " 10KV cable, distribution transformer ground connection copper ring " thus, China Patent No. ZL200620102231.4, its structure comprises the copper ring that is shaped on annular and straight-bar, iron core is installed in the copper ring, copper ring has insulating sleeve outward, the head of copper ring is connected with terminal, and terminal links to each other with the fuse lower end of falling of 10KV cable or 10KV distribution transformer, and an end of copper ring has ground connection to reveal pipe.Its advantage is: cored in copper ring, intensity guarantees, insulating sleeve is arranged outside copper ring, good pressure-resistant performance, safe in utilization, such copper ring has particularly been arranged, what be connected 10KV cable or 10KV distribution transformer falls the fuse lower end, at first carry out electrical verification at dew pipe place during operation, hang up earth connection again, guarantee job safety.But this product can only be used for electrical verification ground connection, lower end at ring can not stube cable, prior art is connecing when tearing branch line or service cable open, need to cut off a last whole piece line powering, the operation that in a single day has a power failure of whole piece circuit, a large number of users is caused heavy losses, and power supply department can't guarantee to reach 99% power supply reliability.Therefore, the someone adopts penetration type transformer wire clamp, installs more conveniently, but penetration type transformer wire clamp exists loose contact, stabs lead easily, and copper aluminium junction when extension disconnects ground wire since on lower pulling force add that again weight can cause shortcomings such as fracture.
Summary of the invention
The purpose of this utility model is in order to overcome the shortcoming of prior art, a kind of electricity testing grounding ring of both having done is provided, direct stube cable again, reduce the length of the binding post and the downlead that fall fuse simultaneously, be used under the situation that supply line does not have a power failure in the lower end, connect and tear threephase cable or distribution transformer downlead open, intensity is good, highly versatile, simply constructed direct fine adjustment type electricity testing grounding ring.
The technical scheme of the direct fine adjustment type electricity testing grounding ring of the utility model is: comprise that ring and the straight-bar made by copper pipe are formed, outside ring and straight-bar, insulating sleeve is arranged, be shaped on upper terminal at the straight-bar head, one at ring has ground connection to reveal pipe, the edge aluminium bar is shaped on hanging hole in it is characterized in that in the described copper pipe in upper terminal, hanging hole with fall fuse and be connected, bottom at ring is shaped on lower terminal, and lower terminal connects the downlead of threephase cable or distribution transformer.
Direct fine adjustment type electricity testing grounding ring of the present utility model both had been used for electrical verification ground connection, be used for the whole piece circuit again and be connected to branch line or service cable, main feature be in copper pipe in the edge aluminium bar; Become the perfect conductor reliable in quality, tear open, hanging earthing conductor intensity is good, the straight-bar upper terminal has hanging hole, with to fall fuse easy to connect,, can on workbench, (bench vice) adjust if vertical angle is improper when installing, adjusting range is in 15 degree, and is simple in structure, uses flexibly; Bottom at ring is shaped on lower terminal, and lower terminal is used to connect 10KV threephase cable or distribution transformer downlead.Therefore, the technical program has solved and can tear, connect cable end and the work of distribution transforming downlead open under the situation of not stopping the upper level main line, overcomes whole piece line outage a large number of users is caused heavy losses, and power supply department guarantees the reliability of power supply.
Direct fine adjustment type electricity testing grounding ring of the present utility model is shaped on connecting hole on its described lower terminal, and connecting hole connects the downlead of threephase cable or distribution transformer, and connecting hole has been arranged, and is easy to connect.Protective jacket is installed in its described lower terminal outside, plays certain insulating effect.
