Abstract
The utility model belongs to the technical field of electric power joints, and particularly discloses a one-step reducing joint of a test current transformer. The technical scheme is as follows: the one-step reducing joint of the test current transformer comprises a conductive base plate, wherein tested equipment guide bar inserting holes and test equipment connecting wire inserting holes are formed on the conductive base plate, and the aperture of the tested equipment guide bar inserting holes is greater than that of the test equipment connecting wire inserting holes; and during a test, the tested equipment guide bar inserting holes of the conductive base plate are fixed on tested equipment guide bars, and test equipment connecting wires are fixed with the test equipment connecting wire inserting holes, so that the test equipment connecting wires can be conveniently connected with the tested equipment guide bars, the working efficiency is greatly improved, test data is more accurate, the cost is greatly reduced, and the one-step reducing joint can be repeatedly used. The one-step reducing joint of the test current transformer overcomes the defects of high cost, inconvenience in disassembly and assembly, incapability of being repeatedly used for a plurality of times and the like of soft copper conducting wires which are adopted at present.
Description
Technical field
The utility model belongs to the Power tabs technical field, a reducer union of particularly a kind of test current mutual inductor.
Background technology
When test large velocity ratio high pressure measurement current transformer; Need guide rod of mutual inductor and single test line nose be connected together; Because guide rod diameter of mutual inductor is greater than the aperture of single test line nose, single test line nose can not directly be enclosed within on guide rod of mutual inductor.Main at present employing test is connected together guide rod of mutual inductor and single test line nose with annealed copper wire, to realize the purpose of test.Mainly there is following defective in this method: one of which, and the annealed copper wire expense is high, and cost is big, and uses several times the back annealed copper wire thigh that can break, and has further increased use cost; Its two, operational sequence is loaded down with trivial details, electric conductivity is influenced and then influence test effect.
The utility model content
The technical matters that the utility model solves just provide a kind of cost low, can repeatedly use, a reducer union of test current mutual inductor safe and convenient to use.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
Comprise electrically-conductive backing plate, be provided with tested device guide rod jack and testing equipment patch jack at described electrically-conductive backing plate.
Its additional technical feature is:
Said tested device guide rod jack and testing equipment patch jack are respectively one;
Said tested device guide rod jack and testing equipment patch jack are respectively two or more.
A reducer union of the test current mutual inductor that the utility model provided is compared with prior art and had the following advantages: one of which is provided with tested device guide rod jack and testing equipment patch jack at described electrically-conductive backing plate by electrically-conductive backing plate owing to comprising; The aperture of tested device guide rod jack is greater than the testing equipment patch jack; When making an experiment, the tested device guide rod jack of electrically-conductive backing plate is fixed on the tested device guide rod, testing equipment wiring and testing equipment patch jack are fixed; Like this; Can easily testing equipment wiring and tested device guide rod be linked together, work efficiency improves greatly, and test figure is more accurate; Cost reduces greatly and is reusable, the shortcoming that the cost that has overcome present employing soft copper lead existence is high, dismounting is inconvenient, can not be repeatedly used; Its two since said tested device guide rod jack and testing equipment patch jack be respectively one, two or more, can be fit to the tested device guide rod and the testing equipment wiring of multiple model, usable range is wider.
Description of drawings
Fig. 1 is the structural representation of the reducer union of test current mutual inductor that the utility model provided;
Fig. 2 is the structural representation of a reducer union of another kind of test current mutual inductor.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the structure of the reducer union of test current mutual inductor that the utility model provided is done further detailed description.
As shown in Figure 1, a reducer union of this test current mutual inductor comprises electrically-conductive backing plate 1, and electrically-conductive backing plate 1 is provided with tested device guide rod jack 2 and testing equipment patch jack 3.The aperture of tested device guide rod jack 2 is greater than the aperture of testing equipment patch jack 3.When making an experiment; The tested device guide rod jack 2 of electrically-conductive backing plate 1 is fixed on the tested device guide rod, testing equipment wiring and testing equipment patch jack 3 is fixing, like this; Can easily testing equipment wiring and tested device guide rod be linked together; Work efficiency improves greatly, and test figure is more accurate, and cost reduces greatly and be reusable.The shortcoming that the cost that has overcome present employing soft copper lead existence is high, dismounting is inconvenient, can not be repeatedly used.
Tested device guide rod jack and testing equipment patch jack are respectively one; Also can be two or more; Tested device guide rod jack as shown in Figure 2 and testing equipment patch jack are respectively 3; Like this, can be fit to the tested device guide rod and the testing equipment wiring of multiple model, usable range is wider.
The foregoing description is the explanation to the utility model; Therefore; The protection domain of the utility model not only is confined to the foregoing description, as long as a reducer union of structure and the utility model test current mutual inductor is identical, just drops on the scope of the utility model protection.
Claims (3)
1. a reducer union of test current mutual inductor is characterized in that: comprise electrically-conductive backing plate, be provided with tested device guide rod jack and testing equipment patch jack at described electrically-conductive backing plate.
2. a reducer union of test current mutual inductor according to claim 1 is characterized in that: said tested device guide rod jack and testing equipment patch jack are respectively one.
