Lub ntsiab Circuit Court ntawm lub mos pib siv lub thyristor.Los ntawm maj mam hloov lub qhib lub kaum sab xis ntawm lub thyristor, qhov voltage yog tsa los ua kom tiav cov txheej txheem pib.Qhov no yog lub hauv paus ntsiab lus ntawm lub soft starter.Nyob rau hauv lub low-voltage soft starter market, muaj ntau yam khoom, tab sis covnruab nrab-voltage soft startercov khoom tseem muaj tsawg.
Lub hauv paus ntsiab lus ntawm nruab nrab-voltage soft starter yog tib yam li cov low-voltage soft starter, tab sis muaj cov nram qab no sib txawv ntawm lawv: (1) Medium-voltage soft starter ua hauj lwm nyob rau hauv high-voltage ib puag ncig, rwb thaiv tsev kev ua tau zoo ntawm ntau yam. cov khoom siv hluav taws xob zoo dua, thiab kev tiv thaiv kev cuam tshuam ntawm cov khoom siv hluav taws xob muaj zog dua.Thaum lubnruab nrab-voltage soft starteryog tsim los rau hauv lub txee hluav taws xob, kev teeb tsa ntawm cov khoom siv hluav taws xob thiab kev sib txuas nrog lub nruab nrab-voltage soft starter thiab lwm yam khoom siv hluav taws xob kuj tseem ceeb heev.(2) Lub nruab nrab voltage soft starter muaj kev ua haujlwm siab tswj cov tub ntxhais, uas tuaj yeem ua cov teeb liab raws sijhawm thiab sai.Yog li ntawd, cov tub ntxhais tswj feem ntau siv cov kev ua haujlwm siab DSP nti, tsis yog qhov hluav taws xob qis qis ntawm MCU core.Lub ntsiab Circuit Court ntawm qis voltage mos pib yog tsim los ntawm peb inversely parallel thyristors.Txawm li cas los xij, nyob rau hauv high-pressure soft starter, ntau high-voltage thyristors nyob rau hauv series yog siv rau voltage division vim tsis txaus voltage kuj ntawm ib tug high-voltage thyristor.Tab sis qhov kev ua tau zoo ntawm txhua tus thyristor tsis zoo ib yam.Qhov tsis sib xws ntawm thyristor tsis sib xws yuav ua rau qhov tsis sib xws ntawm thyristor qhib lub sijhawm, uas yuav ua rau kev puas tsuaj ntawm thyristor.Yog li ntawd, nyob rau hauv kev xaiv ntawm thyristors, thyristor tsis nyob rau hauv txhua theem yuav tsum tau raws li zoo raws li qhov ua tau, thiab cov khoom tsis sib xws ntawm RC lim Circuit Court ntawm txhua theem yuav tsum zoo ib yam li qhov ua tau.(3) Qhov chaw ua haujlwm ntawm nruab nrab-voltage soft starter yog feem ntau cuam tshuam rau electromagnetic cuam tshuam, yog li kev sib kis ntawm cov teeb liab tshwm sim muaj kev nyab xeeb thiab txhim khu kev qha.
Nyob rau hauv nruab nrab-voltage mos pib, lub teeb liab tshwm sim feem ntau kis tau los ntawm fiber ntau optical, uas tuaj yeem zam tau ntau yam kev cuam tshuam electromagnetic.Muaj ob txoj hauv kev los xa cov teeb liab los ntawm fiber ntau optical: ib qho yog fiber ntau, thiab lwm yam yog ib leeg-fiber.Hauv ntau hom fiber ntau, txhua lub rooj tsavxwm muaj ib qho fiber ntau optical.Hauv ib hom fiber ntau, tsuas muaj ib qho fiber ntau hauv txhua theem, thiab cov teeb liab kis mus rau ib lub rooj tsavxwm loj, thiab tom qab ntawd xa mus rau lwm lub rooj tsavxwm hauv tib theem los ntawm lub rooj tsavxwm tseem ceeb.Txij li thaum lub photoelectric kis tsis tau ntawm txhua qhov kho qhov muag fiber ntau tsis zoo ib yam, ib leeg kho qhov muag fiber ntau txhim khu kev qha ntau dua li cov fiber ntau optical los ntawm kev xav ntawm qhov sib xws.(4) Qhov nruab nrab-voltage soft starter muaj ntau dua qhov yuav tsum tau rau lub teeb pom kev zoo dua li qis-voltage soft starter.Muaj ntau ntawm electromagnetic cuam tshuam nyob rau hauv ib puag ncig qhov chaw nruab nrab-voltage soft starter nyob, thiab lub tshuab nqus tsev contactor thiab lub tshuab nqus tsev Circuit Court breaker siv nyob rau hauv lubnruab nrab-voltage soft starteryuav ua rau muaj kev cuam tshuam ntau ntawm electromagnetic cuam tshuam hauv cov txheej txheem ntawm kev tawg thiab kaw.Yog li ntawd, cov teeb liab pom yuav tsum tsis tsuas yog lim los ntawm cov khoom siv kho vajtse, tab sis kuj los ntawm software tshem tawm cov teeb liab cuam tshuam.(5) Tom qab tus pib muag muag ua tiav cov txheej txheem pib, nws yuav tsum tau hloov mus rau lub xeev bypass khiav.Yuav ua li cas smoothly hloov mus rau lub bypass khiav lub xeev kuj yog ib qho nyuaj rau cov mos pib pib.Yuav ua li cas xaiv lub bypass point yog ib qho tseem ceeb heev.Thaum ntxov bypass taw tes, tam sim no poob siab heev, txawm nyob rau hauv tsis tshua muaj voltage tej yam kev mob, yuav ua rau peb-theem fais fab mov Circuit Court breaker mus ncig teb chaws, los yog tej yam kev puas tsuaj rau lub Circuit Court breaker.Qhov kev puas tsuaj yog ntau dua nyob rau hauv cov xwm txheej siab.Lub bypass taw tes yog lig, thiab lub cev muaj zog jitter phem, uas cuam tshuam rau lub cev ua hauj lwm ntawm lub load.Yog li ntawd, lub bypass signal hardware detection Circuit Court yog heev, thiab cov kev pab cuam ua yuav tsum yog xwb.
