AC tswj fais fab mov tswvyim
Lub tswv yim ntawm AC tswj fais fab mov yog ib qho khoom siv hluav taws xob uas tuaj yeem muab lub zog AC ruaj khov rau lub nra. Kuj tseem hu ua AC voltage stabilizer. Rau qhov tsis zoo thiab qhov ntsuas tau zoo ntawm AC tswj fais fab mov, thov xa mus rau DC tswj fais fab mov. Ntau yam khoom siv hluav taws xob xav tau cov khoom siv hluav taws xob AC ruaj khov, tshwj xeeb tshaj yog thaum siv tshuab computer siv rau ntau qhov chaw, cov khoom siv hluav taws xob ncaj qha los ntawm AC daim phiaj tsis muaj kev ntsuas tsis tuaj yeem ua tau raws li qhov xav tau.
AC tswj fais fab mov tswvyim
Ib qho khoom siv hluav taws xob uas tuaj yeem muab lub zog AC ruaj khov rau kev thauj khoom. Kuj hu ua kev sib txuas lus. Kev tswj chaw taws teeb, telesignaling thiab telemetry ntsig txog [2].
Lub hauv paus ntsiab lus thiab muaj pes tsawg leeg ntawm AC fais fab mov
Tam sim no, nyob rau hauv lub hwj chim nroj tsuag, thiaj li hu ua thawj load industrial thiab mining lag luam, thiab ib co substations, lub nruam thiab txhim khu kev qha zog noj yog lub hauv paus mob rau kev nyab xeeb ntawm lub cev muaj zog. Kev sib tiv tauj ncaj qha (los yog ntawm qhov qis-voltage, lub sij hawm ncua relay) pib lub zog rov qab tso zis tawm tswv yim, txoj kev no tsis muaj qhov ntsuas qhov zaus, qhov kev vam meej ntawm lub zog hloov hluav taws xob tsawg lossis lub sijhawm hloov pauv ntev, thiab lub cev muaj zog rov pib dua tam sim no Nws yog qhov loj heev thiab nws yog ib qho yooj yim kom dhau qhov kev tso cai ntawm tus nqi ntau thiab raug puas tsuaj los ntawm kev cuam tshuam, tshwj xeeb tshaj yog nyob rau qee lub sijhawm uas siv lub zog hluav taws xob thiab cov tshuab hluav taws xob siab, vim tias qhov hluav taws xob qeeb qeeb tom qab lub cev muaj zog, yog tias lub lub zog thaub qab yog qhib yam tsis tau kuaj xyuas cov xwm txheej synchronization thaum qhov seem hluav taws xob loj, qhov pib / standby transformer thiab lub cev muaj zog yuav raug puas tsuaj los ntawm kev cuam tshuam loj heev. Yog tias qhov hluav taws xob seem poob mus rau ib theem (xws li ntawm 20[[ feem pua ]]-40[[ feem pua ]]Un), ces muab tso rau hauv lub hwj chim thaub qab. Vim lub sij hawm siv hluav taws xob ntev, qhov ceev ntawm lub tshuab hluav taws xob poob qis heev, thiab qhov pib ntawm tus kheej ntawm cov motors hauv cov pab pawg ua rau lub busbar mus txuas ntxiv kom poob siab, thiab qee lub tshuab pabcuam raug khi kom thim.
Txhawm rau daws cov teeb meem saum toj no, cov cuab yeej no yuav cia li taug qab thiab saib xyuas qhov zaus, qhov hluav taws xob thiab theem ntawm lub zog hluav taws xob ntawm ob qho kawg ntawm kev hloov mus rau lub sijhawm ntev thaum lub sijhawm siv hluav taws xob. Nyob rau tib lub sijhawm, siv tus qauv lej tsim nyog (tsis yog xav txog qhov sib txawv ntawm theem tam sim no thiab qhov sib txawv ntawm qhov sib txawv, tab sis kuj tseem xav txog qhov kev hloov pauv ntawm theem tom ntej qhov sib txawv thiab qhov sib txawv zaus) ua ke nrog lub sij hawm preset ua ntej qhov kev hloov yuav raug kaw, xam cov theem sib txawv thiab zaus ntawm qhov chaw kaw yav tom ntej. Qhov sib txawv yog muab piv nrog rau qhov preset tso cai rau theem sib txawv thiab zaus sib txawv, thiab thaum cov xwm txheej tau ua tiav, nws yuav xa tawm lub teeb liab kaw thiab tripping mem tes.
