Problems solved by technology

[0002] The current transformer coil (iron core) excitation characteristic test, the existing method is to wind a certain design number of turns on the iron core with connecting wires, but the tightness is not uniform when winding manually, and the winding speed is slow , and the wire diameters used are not uniform, which will increase the loss of electric energy and increase the resistance
And when the number of iron cores is large, more wires are used, and the number of repeated windings wastes material costs and labor costs, which has an adverse effect on work efficiency and progress.

Embodiment Construction

[0009] Such as figure 1 Shown is a winding tool for testing the excitation characteristics of a current transformer coil, which includes two insulating plates 1 and a plurality of wires 3, one insulating plate 1 is evenly fixed with a plurality of copper buttons 2, and the other insulating plate 1 A plurality of copper buckle females 4 are evenly fixed on the top, and the copper buckle male 2 corresponds to the copper buckle female 4 one by one. One end of the wire 3 is fixed on a copper buckle male 2, and the other end is fixed on a wire diagonally opposite to the aforementioned copper buckle male 2. After the copper buckle female 4 and the copper buckle male 2 on the two insulation boards 1 are fastened together, a plurality of wires 3 are connected end to end in turn to form a helical coil.

[0010] Test method: during the test, the tooling can be directly wound on the iron core, and then the two insulating plates 1 are pressed tightly, the copper buckle female 4 and the co...

Abstract

The invention discloses an excitation characteristic test coiling frock for a coil of a current mutual inductor. The coiling frock comprises two insulating boards and a plurality of conducting wires, both ends of which are fixed onto the two insulating boards. A locking device is arranged on the two insulating boards. After the two insulating boards are fastened, a plurality of conducting wires are connected end to end in sequence to form a loop. The interval and the length of the conducting wires are fixed, so the coil is coiled up by fastening the two insulating boards only. The test coiling frock has the advantages of even coiling, high working efficiency, small coiling radian and long service life. In addition, materials and labor are saved.

Description

(1) Technical field [0001] The invention relates to a test device, in particular to a winding tool for testing the excitation characteristics of a current transformer coil. (2) Background technology [0002] The current transformer coil (iron core) excitation characteristic test, the existing method is to wind a certain design number of turns on the iron core with connecting wires, but the tightness is not uniform when winding manually, and the winding speed is slow , and the wire diameters used are not uniform, which will increase the loss of electric energy and increase the resistance. Moreover, when the number of iron cores is large, the number of wires used is relatively large, and the number of times of repeated windings wastes material costs and labor costs, which has an adverse effect on work efficiency and progress. (3) Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a winding tool for testing the excita...
