(4) Muaj ob hom lub cev muaj zog cua sov: kev faib kab rov tav thiab kev faib hluav taws xob, nrog rau kev faib kab rov tav ua qhov tseem ceeb.

(5) Tag nrho cov koob siv cov kabmob pob sib sib zog nqus uas tsis muaj suab nrov, thiab qhov siab nruab nrab ntawm lub rooj zaum yog 180 hli saum toj no lub cev muaj zog yog nruab nrog cov roj txhaj thiab cov khoom siv tawm.

(6) Qib tiv thaiv plhaub nce mus txog IP55.

(7) Cov ntsuas kev ua tau zoo tseem ceeb kom ncav cuag theem siab thoob ntiaj teb thaum ntxov xyoo 1990s.

(Nyob rau hauv lub qhov rais)Cov cav uas txhim kho kev nyab xeeb

Nyob rau saum cov qauv ntawm lublub cev muaj zog, uas tsis tsim cov arcs, sparks lossis qhov kub siab txaus ntshai nyob rau hauv cov xwm txheej ua haujlwm ib txwm muaj, kev ntsuas kev siv tshuab, hluav taws xob thiab thermal raug coj los ntxiv kom tsis txhob muaj kev pheej hmoo ntawm arcs, sparks lossis qhov kub siab nyob rau hauv cov xwm txheej ib txwm muaj lossis lees paub overload, yog li ua kom nws muaj kev nyab xeeb tawg.

Cov yam ntxwv tseem ceeb:

(1) Nws ua tau raws li qhov yuav tsum tau ua ntawm cov cav tsis tawg nrog kev nyab xeeb ntxiv, thiab siv ntau yam kev ntsuas kom ntseeg tau los tiv thaiv cov hluav taws xob, arcs thiab qhov kub siab txaus ntshai, yog li nws tuaj yeem ua haujlwm tau zoo hauv thaj chaw txaus ntshai Cheeb Tsam 2.

(2) Txais yuav brushless excitation, teeb tsa rotating rectifier disk thiab static excitation txee, txhim khu kev qha excitation tswj system; raug thiab shockless excitation nrog down-polarity rotating sib txawv; txhim khu kev qha tawm-ntawm-kauj ruam kev tiv thaiv ntawm excitation system thiab muaj zog muaj peev xwm ntawm re-kauj ruam rectification; tsim nyog tsim ntawm kab, tso tawm resistor tsis kub thaum lub sijhawm ua haujlwm; ntau yam ntawm excitation tam sim no hloov kho.
