MYG-RSO 與蘇瑪創(chuàng)RSO技術(shù)比較之二
英國專家的專業(yè)意見,供用戶參考!
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.
通過剛才快速地瀏覽蘇瑪創(chuàng)RSO的用戶使用手冊,相對于MYG-RSO,蘇瑪創(chuàng)RSO的設(shè)備相對簡陋 。
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.
這里強(qiáng)調(diào)一點(diǎn), 蘇瑪創(chuàng)-RSO設(shè)備需要操作人員來調(diào)整電位器去獲得完全相同的注入發(fā)電機(jī)轉(zhuǎn)子兩端的脈沖軌跡。 (而MYG-RSO則是自動完成)當(dāng)轉(zhuǎn)子繞組非常完美的時候,蘇瑪創(chuàng)RSO非常容易通過電位器調(diào)整來獲得脈沖軌跡。但是,當(dāng)本身發(fā)電機(jī)轉(zhuǎn)子繞組存在故障或者其他問題,那么它可能非常困難去調(diào)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.
同時,蘇瑪創(chuàng)是同時往轉(zhuǎn)子繞組線圈注入脈沖,這就解釋了我之前提出來的它為什么不得不采用短脈沖。否則它會在示波器上面的顯示重疊的脈沖。與之相反,更完善的操作模式,MYG-RSO使用交替的激勵脈沖安排, 這脈沖交替地重復(fù)地注入發(fā)電機(jī)轉(zhuǎn)子繞組線圈的兩端。通過一個電子轉(zhuǎn)換開關(guān),這些脈沖重復(fù)率可達(dá)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.
這需要使用較長、較高能量的脈沖,同時確保示波器的不同波形不會由于錯誤操作而得到。此外,MYG-RSO與蘇瑪創(chuàng)RSO最大的不同是,MYG-RSO提供一個演示延遲線,方便用戶在沒有發(fā)電子轉(zhuǎn)子繞組的情況下,檢驗(yàn)我們的設(shè)備是否工作正常。同時可以看到模擬的匝間短路和接地故障時的RSO波形。
