Description
Technical field
The utility model relates to a kind of termination, particularly relates to a kind of termination for transformer synthesis test.
Background technology
Power transformer is one of major equipment of generating plant and electric substation.The effect of transformer is many-sided, boosted voltage electric energy can not only be delivered to electricity consumption area, voltage can also be reduced to use voltage at different levels, to meet the needs of electricity consumption.In a word, boosting and step-down all must have been come by transformer.Transmit in electric system in the process of electric energy, will inevitably produce voltage and the loss of power two parts, when carrying same power, voltage loss and voltage are inversely proportional to, square being inversely proportional to of power attenuation and voltage.Utilize transformer to improve voltage, decrease power transmission loss.
Voltage transformer is arranged on the height up to about 4 meters usually, and therefore, carrying out in the process of the test of carrying out for power transformer, wiring is carried out in the position needing staff to climb to 4 meters high, the more enterprising line transformer test in bottom surface.But same power transformer often needs to carry out Multitest, for this reason, often launching a test all needs staff's wiring that climbs up to climb down to detect again, so not only arduous but also lose time, therefore design a kind of can just seeming particularly necessity by the primary connection termination tested for transformer synthesis that just can meet test of many times needs.
Utility model content
The utility model provides a kind of termination for transformer synthesis test, which overcomes the deficiencies in the prior art described in background technology.
The utility model solves the technical scheme that its technical matters adopts:
For a termination for transformer synthesis test, it comprises terminal block and test lead, and described terminal block is provided with terminals A1, terminals B1, terminals C1, terminals N1, and terminals A2, terminals B2, terminals C2, terminals N2; Described terminals A1, terminals B1, terminals C1 and terminals N1 are by four leading-out terminals of described test lead connection transformer, and described terminals A2, terminals B2, terminals C2 and terminals N2 are by test lead connecting test instrument; Described terminals A1 and terminals A2, terminals B1 and terminals B2, terminals C1 and terminals C2, terminals N1 and terminals N2 are all connected by the connection wire be located on terminal block.
Among one embodiment: the test lead adjustable length between described transformer and terminal block.
Among one embodiment: described terminals A1, terminals B1, terminals C1, terminals N1, terminals A2, terminals B2, terminals C2 and terminals N2 are all equiped with the plastic cap nut for fastening test lead terminals.
Among one embodiment: described connection wire and plastic cap nut are located at the positive and negative of terminal block respectively.
The technical program is compared with background technology, and its tool has the following advantages:
The utility model structure is simple, cost is low; The repeatedly high-altitude wiring of script transformer is become ground wiring, simple to operate, easy to use, and test process is safer, more laborsaving.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 depicts the wiring schematic diagram of the termination for transformer synthesis test.
Fig. 2 depicts the structural representation of terminal block.
Embodiment
Please refer to Fig. 1 and Fig. 2, a kind of termination for transformer synthesis test, it comprises terminal block 10 and test lead 20, and described terminal block 10 is provided with terminals A1, terminals B1, terminals C1, terminals N1, and terminals A2, terminals B2, terminals C2, terminals N2; Described terminals A1, terminals B1, terminals C1 and terminals N1 are by four leading-out terminals of described test lead 20 connection transformer 30, and described terminals A2, terminals B2, terminals C2 and terminals N2 are by test lead 20 connecting test instrument 40; Described terminals A1 and terminals A2, terminals B1 and terminals B2, terminals C1 and terminals C2, terminals N1 and terminals N2 are all connected by the connection wire 11 be located on terminal block 10.Test lead adjustable length between described transformer 30 and terminal block 10.Described terminals A1, terminals B1, terminals C1, terminals N1, terminals A2, terminals B2, terminals C2 and terminals N2 are all equiped with the plastic cap nut (not shown) for fastening test lead 20 terminals.Described connection wire 11 and plastic cap nut are located at the positive and negative of terminal block 10 respectively.
A kind of termination structure for transformer synthesis test described in the utility model is simple, cost is low; The repeatedly high-altitude wiring of script transformer is become ground wiring, simple to operate, easy to use, and test process is safer, more laborsaving.
The above, be only the utility model preferred embodiment, therefore the scope that the utility model implements can not be limited according to this, the equivalence namely done according to the utility model the scope of the claims and description change with modify, all should still belong in scope that the utility model contains.
