Embodiment

Elaborate below in conjunction with the embodiment of accompanying drawing to a kind of magnet ring measurement mechanism that the utility model provides.

See Fig. 1 and Fig. 2, a kind of magnet ring testing device of the utility model, comprises conductive handle 1 and a conducting bracket 2.The material of described conducting bracket 2 and conductive handle 1 can be selected from metal, such as, can be copper.

One end of described conductive handle 1 is connected to the driving source (not indicating in accompanying drawing) of external test facility by limit, a source excitation wire 3, the other end is connected to the test lead (not indicating in accompanying drawing) of external test facility by a secondary test lead 5.Described external test facility is device well known in the art, is not repeated herein.In this embodiment, described conductive handle 1 is a straight-bar, so that overlap with described conducting bracket 2.

Described conducting bracket 2 is fixed on an insulator foot 7.In this embodiment, described conducting bracket 2 is L-type, wherein minor face is fixedly connected with insulator foot 7, long limit is parallel with insulator foot 7, magnet ring 8 to be tested can be passed in the long limit of described conducting bracket 2, namely described magnet ring to be tested 8 can be inserted on the long limit of described conducting bracket 2, realizes being connected to make magnet ring 8 to be tested and described magnet ring testing device.One end of described conducting bracket 2 is connected to the driving source of described external test facility and the test lead of described external test facility respectively by limit, a source excitation wire 4 and a secondary test lead 6.

In the utility model, the connection of described source limit excitation wire and secondary test lead and conductive handle 1 and conducting bracket 2 connects by mode well known to those skilled in the art, and the utility model does not limit.In the accompanying drawings, only adopt the mode of winding, schematically show its annexation.

See Fig. 3 and Fig. 4, described conductive handle 1 can overlap with the other end of described conducting bracket 2, make the driving source of limit, described source excitation wire, conducting bracket 2, conductive handle 1 and described external test facility form limit, a source energized circuit, the test lead of described secondary test lead, conducting bracket 2, conductive handle 1 and external test facility forms a secondary test loop.Described conducting bracket 2, through magnet ring 8 to be tested, passes described magnet ring 8 to be tested to make limit, source energized circuit and secondary test loop.

Open the driving source of described external test facility, then can form exciting current in the energized circuit of limit, described source, in the energized circuit of limit, described source, have exciting current, then can make to produce induced potential in secondary test loop, thus measuring equipment can measure magnetic to be tested, 8 individual pen inductance values.

Usually, to realize the test of magnet ring individual pen inductance value fast, first need to realize fast the source of magnet ring 8 to be tested, the building of subloop.

See Fig. 5, limit, source energized circuit is connected by A, B 2 with secondary test loop, and during test magnet ring, A, B 2 connects conducting in magnet ring 8 hole to be tested, on magnet ring, so just define limit, source energized circuit and secondary test loop.Now, if curent change in the energized circuit of limit, source, corresponding secondary test loop has induced potential and produces, and limit, source excitation voltage waveform and secondary test voltage wave are as shown in Figure 5.
