MYG-RSO 与苏玛创RSO技术比较之二

英国专家的专业意见，供用户参考！

I have just had a quick look at theSumatron Instruction Manual (copy attached).
It is clear from this that the Sumatron device is relatively simple compared
with both our MYG-RSO units.

通过刚才快速地浏览苏玛创RSO的用户使用手册，相对于MYG-RSO，苏玛创RSO的设备相对简陋 。
In particular, it is necessary for the operator to adjust 2 potentiometers to
obtain identical traces at each end of the rotor winding (the MYG-RSO units
do this automatically). It is fairly easy to make this adjustment whenthe rotor
winding is perfect, but if there are faults or other problems in the winding,it
can be difficult to judge when the potentiometers have been balanced correctly.

这里强调一点， 苏玛创-RSO设备需要操作人员来调整电位器去获得完全相同的注入发电机转子两端的脉冲轨迹。 （而MYG-RSO则是自动完成）当转子绕组非常完美的时候，苏玛创RSO非常容易通过电位器调整来获得脉冲轨迹。但是，当本身发电机转子绕组存在故障或者其他问题，那么它可能非常困难去调整。
Also, I think Sumatron use simultaneous injection of pulses from each end of of
the rotor winding. This explains why they have to use short pulses, otherwise
they would get superimposed pulses displayed on the oscilloscope channels.
In complete contrast, in the preferred mode of operation, the MYG-RSO units
use an alternate pulse excitation arrangement, where the excitation pulses are
injected at each end of the rotor winding alternately and at a high repetition
rate (up to 1000 times per second) using an electronic switching network.

同时，苏玛创是同时往转子绕组线圈注入脉冲，这就解释了我之前提出来的它为什么不得不采用短脉冲。否则它会在示波器上面的显示重叠的脉冲。与之相反，更完善的操作模式，MYG-RSO使用交替的激励脉冲安排， 这脉冲交替地重复地注入发电机转子绕组线圈的两端。通过一个电子转换开关，这些脉冲重复率可达1000次/s。

This allows the use of longer,higher-energy pulses and also ensures that different
oscilloscope traces cannot be obtained as a result of operator error.
A futhur difference between the Sumatron equipment and the MYG-RSO units is that we
supply a demonstration delay line with each of our systems so that users can
both check that the equipment is working correctly in the absence of an
available rotor winding and also see the effects of applied simulatedinter-turn
and earth faults on the RSO waveforms.

这需要使用较长、较高能量的脉冲，同时确保示波器的不同波形不会由于错误操作而得到。此外，MYG-RSO与苏玛创RSO最大的不同是，MYG-RSO提供一个演示延迟线，方便用户在没有发电子转子绕组的情况下，检验我们的设备是否工作正常。同时可以看到模拟的匝间短路和接地故障时的RSO波形。
