Description
Technical Field
The utility model relates to a cable detects technical field, specifically is to relate to a cable tester of transformer substation.
Background
In the transformation process, most cables are composed of a plurality of strands of wires, a multimeter is required to be used for testing the corresponding relation of the wire heads at the head end and the tail end of each cable one by one at a working site, the process is time-consuming and labor-consuming, a lot of time is needed for calibrating the fifty-six ten-core cables, dozens of and hundreds of cables are often needed to be calibrated in one station, the multimeter is too short in wire, the wire calibration function is difficult to realize, sometimes, because the wires are two, the head distance is far, two parties are needed to assist and talk in real time, the efficiency is extremely low, meanwhile, due to the fact that the wires are relatively long, the on-off condition of the cables is difficult to judge, and great troubles are brought to daily work; therefore, a quick, efficient and accurate cable calibration instrument capable of being operated by a single person is urgently needed to save the working time in the working aspect.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects in the prior art, the utility model provides a cable tester for a transformer substation; the structure of the tester is that a power line (5) is respectively connected with an input line of a voltmeter A (1), a voltmeter B (2), a voltmeter C (3) and a voltmeter D (4) on a tester host, the voltmeter A (1), the voltmeter B (2), the voltmeter C (3), an output lead D (9) of the voltmeter D (4), a lead C (8), a lead B (7), a lead A (6) is connected with one end cell A of a cable, a cell B, the cell C and a cell D, the other end cell A of the cable, the cell B, the cell C, the cell D and the output lead D (9) of the tester slave computer, the lead C (8), the lead B (7) and the lead A (6).
The voltmeter is a digital voltmeter.
Voltmeter A (1), voltmeter B (2), voltmeter C (3), voltmeter D (4) all set up in the casing.
The utility model discloses a use method does: when testing is needed, according to the wire head of the tester host and the tester slave shown in fig. 2, and the electric cores of the cable are fixedly connected by using the crocodile clip, after the tester host and the tester slave are electrified, the two electric cores are judged to be the same electric core through the condition that the numerical values on the voltmeters at the two ends are the same or the difference value is the minimum, the corresponding electric core mark is made after the testing is finished, and the tester host and the tester slave are detached.
The beneficial effects of the utility model reside in that: the transformer substation cable detector has the function of simultaneously checking up to ten secondary cables, has the advantages of simplicity and reliability, greatly saves labor time, improves working efficiency, and can test the on-off condition of the cables and whether the cables are grounded; the cable testing work does not waste a large amount of time and labor; the test accuracy can be better than that of the traditional universal test method; the speed of arranging equipment and connecting cables is saved by more than half of the time of the original multimeter test method.
