Description
Technical field
The present invention relates to manganese-zinc ferrite magnet ring Quality Detection technical field, in particular to a kind of peak-to-peak value of magnet ring and
The detection method of root value.
Background technique
Currently, in the market the use of energy-saving lamp be it is very universal, need to use magnet ring in energy-saving lamp, magnet ring needs
Test the parameters such as peak-to-peak value, root-mean-square value, it is desirable that these parameters will meet standard.
Among sine voltage, the magnitude of amplitude can be expressed as peak-to-peak value (Vpp), virtual value (rms) or average value
(ap).Peak-to-peak value Vpp (peak-to-peak value) is exactly that maximum voltage value subtracts minimum amount of voltage that, is the maximum value of entire vibration course, i.e.,
Difference between posivtive spike and negative peak；Root-mean-square value (Vm) is also referred to as virtual value, it may be an indicator that the ability of signal transmitting power.It is square
Root is square averaging to signal waveform, then carries out evolution.
Since the two parameters are not the characterisitic parameter of magnetic material itself, being only placed in specific circuit could be into
Row detection, therefore never a kind of good method detects peak-to-peak value and root-mean-square value in magnet ring production.
Summary of the invention
In order to solve the above technical problems, the present invention provides the detection method of a kind of magnet ring peak-to-peak value and root-mean-square value, by letter
Number signal generator, power amplifier and oscillograph link together, and form closed circuit；Three machines are switched on, while
5 circle enameled wires are wound on magnet ring, two stitches are connected on two connectors of function signal generator, in function signal generator
20KHz, 1A are inputted, key player on a team's waveform is selected in oscillograph, the knob of regulation power amplifier occurs one at this time on oscillograph
Peak-to-peak value and root-mean-square value is illustrated below out in sinusoidal waveform, the waveform.
The present invention sorts detection method in the detection of Mn-Zn soft magnetic ferrite product quality, peak-to-peak value and root-mean-square value
Detect process, by using this method, can peak-to-peak value to the magnet ring sintered and root-mean-square value detect, meet
The requirement of client promotes the quality of product.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the detection device of magnet ring peak-to-peak value and root-mean-square value of the present invention.
Specific embodiment
The present invention is in the Quality Detection process of magnet ring.
The method of the present invention process: function signal generator 1, power amplifier 2 and oscillograph 3 are linked together, specifically
Connection type such as figure one: three machines are switched on, while winding 5 circle enameled wires on magnet ring, two stitches are connected to function signal
On two connectors of generator, 20KHz, 1A are inputted in function signal generator, key player on a team's waveform is selected in oscillograph, are adjusted
The knob of power amplifier will appear a sinusoidal waveform at this time on oscillograph, can be shown below the waveform peak-to-peak value and
Root value.
Using frock clamp of the invention, it is able to detect the peak-to-peak value and root-mean-square value of magnet ring.
These problems that the present invention is detected for magnet ring product in peak-to-peak value and root-mean-square value, by oscillograph, function signal
Generator and power amplifier are combined, and can detect the peak-to-peak value and root-mean-square value of magnet ring by the detection method.
The quality that ensure that product, saves manpower and material resources, improves efficiency and benefit.
Finally, it should be noted that the foregoing is only a preferred embodiment of the present invention, it is not intended to restrict the invention,
Although the present invention is described in detail referring to the foregoing embodiments, for those skilled in the art, still may be used
To modify the technical solutions described in the foregoing embodiments or equivalent replacement of some of the technical features.
All within the spirits and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in of the invention
Within protection scope.
