Abstract
The utility model provides a connecting device of a transformer test wire clamp and a cross-core current rise wire. A connecting current-conducting plate is arranged between the transformer test wire clamp and the cross-core current rise wire, wherein one end of the connecting current-conducting plate is provided with a through hole having a diameter identical to that of a through hole in a cross-wire current rise wire connector, and the other end of the connecting current-conducting plate is provided with a through hole having a diameter identical to a connecting hole in the transformer test wire clamp. The connecting current-conducting plate and the cross-core current rise wire connector, and the connecting current-conducting plate and the transformer test wire clamp are respectively connected through bolts and nuts. According to the connecting device, a connecting angle of the wire clamp can be adjusted freely, and thus heating of the connector during a test process is prevented.
Description
Technical field
The utility model relates to a kind of coupling arrangement, more particularly relates to the coupling arrangement of a kind of transformer test wire clamp and punching up-flow line.
Background technology
Current transformer plays very important effect in electric system, be at indispensable equipment in aspect such as relay protection, automatically control, signal designations.And the no-load voltage ratio attribute testing is one of very important characteristic of current transformer, because in the no-load voltage ratio attribute testing process, the test current that the punching line passes through can be very large, and the metal wire clamp is different from the through-hole diameter of punching up-flow wire terminal place, cause between metal wire clamp and the punching up-flow line connect when being connected with bolt firm not, and cause when clamp loosening easily, wire clamp turns to inconvenience, be difficult to find suitable angle during with equipment connection, cause joint in test process, to generate heat, even might rise less than test current or cause error of test data larger.
Summary of the invention
For overcoming the shortcoming that exists in the prior art, the utility model provides the coupling arrangement of a kind of transformer test wire clamp and punching up-flow line, and this apparatus structure is simple, is connected firmly.
The utility model is achieved through the following technical solutions: the coupling arrangement of a kind of transformer test wire clamp and punching up-flow line, between transformer test wire clamp and punching up-flow line, be provided with and be connected current-carrying plate, one end of described connection current-carrying plate be provided with the wire terminal of punching up-flow on the through hole of through hole same diameter, the other end be provided with the transformer test wire clamp on the through hole of connecting hole same diameter, connect to reach between current-carrying plate and the wire terminal of punching up-flow to be connected between current-carrying plate and the transformer test wire clamp and be connected by bolt and nut respectively.
In the such scheme, described connection current-carrying plate is copper material.
The coupling arrangement of a kind of transformer test wire clamp of the utility model and punching up-flow line has following beneficial effect compared with prior art:
1, this apparatus structure is simple, connects reliable;
2, use this device to connect the connection angle that to adjust arbitrarily wire clamp, avoided joint in test process, to generate heat.
Description of drawings
Fig. 1 is the structural representation of the coupling arrangement of the utility model transformer test wire clamp and punching up-flow line;
Fig. 2 is the A-A cut-open view among Fig. 1.
Among the figure: 1. punching up-flow wire terminal, 2. bolt 3. connects current-carrying plate, 4. bolt, 5. wire clamp web joint, 6. transformer test wire clamp, 7. nut, 8. nut.
Embodiment
Be further described below in conjunction with accompanying drawing and the specific embodiment coupling arrangement to the utility model transformer test wire clamp and punching up-flow line:
Fig. 1 is the structural representation of the coupling arrangement of the utility model transformer test wire clamp and punching up-flow line, and Fig. 2 is the A-A cut-open view among Fig. 1.Among the figure, between transformer test wire clamp 6 and punching up-flow wire terminal 1, be provided with and be connected current-carrying plate 3, an end that connects current-carrying plate 3 be provided with punching up-flow wire terminal 1 on the through hole of through hole same diameter, the other end be provided with transformer test wire clamp 6 on the through hole of connecting hole same diameter, connect between current-carrying plate 3 and the punching up-flow wire terminal 1 to be connected with nut by bolt 2 and be connected, are connected with nut by bolt 4 between connection current-carrying plate 3 and the transformer test wire clamp 6 and are connected.
In use can smear conductive paste at hole wall and the surface of contact of connecting hole, this device has two tie points, more easily turns to, and is easy to operate, can adjust arbitrarily the connection angle of wire clamp, avoided joint to generate heat in test process.The method can be used in any connection in the good not situation with wire clamp, such as doing the loop resistance test, can be used with overhead jointing clamp.
The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, although the utility model discloses as above with preferred embodiment, yet be not to limit the utility model, any those skilled in the art, within not breaking away from the technical solutions of the utility model scope, when the method that can utilize above-mentioned announcement and technology contents are made a little change or be modified to the equivalent embodiment of equivalent variations, in every case be the content that does not break away from technical solutions of the utility model, any simple modification that foundation technical spirit of the present utility model is done above embodiment, equivalent variations and modification still belong in the scope of technical solutions of the utility model.
