最近公司很多客戶詢問MYG-RSO與蘇瑪創(chuàng)RSO的區(qū)別,經(jīng)過咨詢英國專家,這里統(tǒng)一做闡述說明:
1. MYG-RSO與蘇瑪創(chuàng)RSO這兩種RSO產(chǎn)品,我司都有代理。不過我們推薦客戶選用MYG-RSO。
2. MYG-RSO技術(shù)是源于英國,采用的是CEGB原創(chuàng)性技術(shù),設(shè)備是英國生產(chǎn)。
3. 蘇瑪創(chuàng)RSO是美國生產(chǎn)。
詳細技術(shù)比較如下:
MYG-RSO與蘇瑪創(chuàng)RSO的比較說明:
Bothmethods are in general use and both can detect shorted turns and earth faults.However, if the pulse is short, it can be severely attenuated by some rotorwindings, particularly those on older generators and salient pole hydro-generators.
這兩種方法都可以測試轉(zhuǎn)子匝間短路及轉(zhuǎn)子接地故障。但是,蘇瑪創(chuàng)RSO用的是短波,MYG-ROS用的是長波(電壓階梯)。如果使用短波,在某些轉(zhuǎn)子線圈,特別是一些老機組或者水電機組的突極轉(zhuǎn)子,它會嚴重衰減,變得不太可靠。
The MYG-RSO method we use (long pulse) is based on original research at the UKCentral Electricity Generating Board (CEGB) in 1973 and has been usedsuccessfully in the UK and most other countries throughout the world for thelast 40 years.
MYG-RSO技術(shù)(長波)是源于英國中央電力局(CEGB)1973的原創(chuàng)性技術(shù)研究,它成功地在英國及世界范圍內(nèi)應(yīng)用了40多年。技術(shù)非??煽考皳碛斜姸鄳?yīng)用業(yè)績及用戶。
However, if a customer has a history of test test results obtained using theshort pulse method, they will probably prefer to keep using this method so thatthey can compare results for generators over an extended time period.
然而,如果客戶已經(jīng)使用蘇瑪創(chuàng)(短波)技術(shù)方法,他們可能更愿意使用這種方法,因為他們可以利用原來的測試數(shù)據(jù)進行跟蹤測試。但是在國內(nèi),這種用戶非常少。
The main advantage of our equipment is that the RSO pulses at each end of therotor windings can be viewed simultaneously in real-time and that it isimpossible for a user to obtain different RSO traces for a fault-free rotorwinding by incorrect adjustment of the controls.
MYG-RSO最大的優(yōu)點是RSO測試脈沖能夠非常及時地在發(fā)電機轉(zhuǎn)子兩個輸入端觀察到,并且它不會由于用戶的不當操作或者不當調(diào)整產(chǎn)生誤判
Both of these points are important, as they allow the MYG-RSO equipment to beused by relatively unskilled staff and allow faults to be seen a soon asthey occur (for example during a repair or running test) instead of having towait to compare 2 separate traces on an oscilloscope.
基于前面的幾點闡述,MYG-RSO最具有優(yōu)越性的是它允許不太熟練的用戶操作并它能立馬能看到故障(在停機或者空轉(zhuǎn)狀態(tài)),而不用等到來比較示波器上兩個獨立的脈沖軌跡來發(fā)現(xiàn)問題。
