Kev Txhim Kho Qhov Xwm Txheej Hluav Taws Xob Morteng: Kev Tshawb Pom thiab Kev Kho Kom Zoo
(1) Kev Tswj Xyuas Tam Sim No
Saib xyuas lub cev muaj zog ua haujlwm tas li kom ntseeg tau tias nws tseem nyob hauv qhov txwv tam sim no raws sijhawm, tiv thaiv kev overloads uas ua rau cov txhuam hnyav nce sai sai, hnav sai sai, lossis hluav taws xob ntau dhau. Siv lub cev muaj zog lub cuab yeej saib xyuas tam sim no rau kev taug qab lub sijhawm tiag tiag. Yog tias muaj kev overloads ntau zaus tshwm sim, tshawb xyuas cov teeb meem sib phim ntawm cov khoom thauj (piv txwv li, kev sib tsoo ntawm lub tshuab, cov khoom thauj ntau dhau lub peev xwm tsim lub cev muaj zog) thiab siv cov kev ntsuas kho kom raug raws sijhawm.
(2) Kev Sib Npaug ntawm Morteng Brush Current Distribution
Siv cov ntsuas kub infrared los ntsuas qhov kub ntawm cov txhuam. Qhov kub sib txawv ntau feem ntau qhia txog qhov faib hluav taws xob tsis sib xws.
Thaum siv cov clamp-on ammeters, ua haujlwm raws li kev taw qhia ntawm cov kws tshaj lij (zam kom tsis txhob muaj cov cheeb tsam cuam tshuam ntawm lub zog sib nqus ntawm lub cev muaj zog) kom ntsuas ncaj qha cov hluav taws xob ntawm txhua txhuam Morteng, ntsuas qhov hnyav ntawm qhov tsis sib npaug.
Kev Xaiv Txhuam Morteng Zoo Tshaj Plaws: Kev Sib phim Cov Xwm Txheej Ua Haujlwm yog Qhov Tseem Ceeb
(i) Cov Ntsiab Cai Xaiv Tseem Ceeb
Xaiv raws li qhov xwm txheej ua haujlwm tiag tiag, koom tes nrog cov neeg muab txhuam lossis cov chaw tsim khoom siv lub cev muaj zog rau cov kev daws teeb meem tshwj xeeb. Cov kev ntsuas tseem ceeb suav nrog qhov ceev tam sim no, qhov ceev ntawm lub commutator, qhov hluav taws xob ua haujlwm, cov yam ntxwv ntawm lub nra, thiab cov xwm txheej ib puag ncig.
(ii) Cov Kev Xaiv Uas Muaj Lub Hom Phiaj
Kev kub hnyiab ntau dhau thiab kev sib hloov pauv nyuaj: Xaiv cov txhuam uas muaj kev ua tau zoo dua, xws li cov khoom siv carbon-graphite lossis electrographite. Lawv qhov kev tiv taus nruab nrab ua rau kev kub hnyiab tsis ua haujlwm zoo, txo qhov puas tsuaj ntawm arc rau cov commutators thiab txhuam.
Siv Txhuam Ntau Dhau:
Xaiv raws li qhov ceev ntawm tam sim no. Rau cov ntawv thov uas muaj tam sim no ntau, xaiv cov txhuam hlau-graphite. Rau cov xwm txheej ib txwm muaj, xaiv cov txhuam electrographite tawv kom txhim kho kev tiv taus thiab kev siv tau ntev.
Kev Hloov Kho Rau Ib Puag Ncig Tshwj Xeeb: Hauv qhov kub thiab txias, siv cov txhuam graphite uas sib txuas nrog cov resin uas tiv taus kub; rau ib puag ncig corrosive, xaiv cov txhuam nrog cov txheej tiv thaiv xeb lossis cov ntaub ntawv tshwj xeeb kom tiv thaiv cov khoom puas tsuaj thiab ua tsis tiav.
III. Kev Txhim Kho DC Lub Cev Muaj Zog: Kev Kho thiab Kev Txij Nkawm Los Ntawm Kws Tshaj Lij
(I) Kho kom zoo dua qhov chaw tuav txhuam
Nyob rau hauv kev taw qhia ntawm cov kws tshaj lij tsim nyog, kho qhov chaw ntawm lub txhuam kom kho qhov nruab nrab, yog li ntawd txo qhov kev hloov pauv hluav taws xob. Kev kho yuav tsum muaj kev txav me me ntawm lub txhuam. Tom qab txhua qhov kev hloov kho, ua qhov kev sim khiav kom pom qhov kev hloov pauv hluav taws xob kom txog thaum muaj hluav taws xob tsawg kawg nkaus thiab ua haujlwm du.
