1. Rau cov kiv cua thiab cov twj, xaiv cov khoom siv lub xov tooj kom tsim nyog raws li cov kev ntsuas / cov khoom pov npav / nom tswv muaj zog ntawm lub cav; rau lub hwj chim ntawm qhov tsis tas li xws li siv cov khoom siv thauj khoom, xaiv cov zaus hloov qhov haum rau kev khiav hauj lwm tus cwj pwm raws li kev mob. Siv cov khoom siv thauj khoom siv los yog nqa winch siv raws li nram no, thiab xaiv plaub-quadrant inverter. Lub zog ntawm lub inverter yuav tsum raug xaiv nrog reference rau cov nqi tam sim no ntawm lub cav thiab ntau dua li ib theem ntawm lub tshuab kom ua tau raws li qhov yuav tsum tau ua rau cov khoom hnyav pib. Rau qhov sib sib zog nqus dej twj zoo (cov twj submersible) thauj khoom, tsis zoo li cov twj tso tawm dav dav, vim qhov nyob deb ntawm lub inverter mus rau lub cav, nws yog qhov tsim nyog yuav tau nce cov zis sine yoj lim kom zoo zis hluav taws xob thiab tam sim no waveform thiab kev tsav tsheb; Thaum cov paib hloov lub cav ntog cov dej twj ntsaws, vim cov twj tso kua nplaum muaj qhov cub cub, uas yog siab dua qhov kev ceev, ntau dua qhov kev ua haujlwm, yog li pib lub sij hawm ntawm qhov inverter yuav tsum tsis txhob ntev dhau, cov twj tso kua mis tsis muaj peev xwm tsim tau lub tshuab nqus tsev vim nws tsis tuaj yeem muab dej rau; Cov dej "dej nyhuv dej" ntawm lub tshuab tso dej, txwv tsis pub nws yuav ua rau lub raj xa dej mus thiab ua rau raug mob loj. Rau cov kiv cua load, thaum debugging, xyuam xim rau cov kev sib hloov ntawm lub kiv cua tuaj mus ua lub inverter pib tshaj-tam sim no, yog li kom nce DC braking ua ntej startup, thawj ua lub blades ruaj khov, thiab mam li pib lub cav.
2. Qhov teeb meem hauv hluav taws xob hauv hluav taws xob: Cov hluav taws xob uas tsis muaj teeb meem nyob rau hauv av, ua tib zoo saib rau qhov chaw sib txuam ntawm cov cua kub ua haujlwm xws li reactor thiab inverter, thiab sim kom tsis txhob "cua daj cua dub", uas yog, qhov kub cua ntawm cov reactor nkag rau hauv inverter, uas yuav cuam tshuam rau qhov txias ntxim. . Rau cov mining tawg-pov thawj inverters, lawv feem ntau yog siv cov yeeb nkab cua txias tshuab, thiab tseem siv cov dej kub cua txias dissipation tshuab. Thaum tsim cov tshuab cua txias, lawv tsuas yog tsim raws li cov qib sib txawv zog, thaum xa mus rau lub hwjchim ntawm lub hwjchim (nrog rau lub xeev poob) ntawm cov qauv inverter. Thiab cov kev hloov tsis tau yog xam, thiab yog ib qho paj tau paj, thiab cov cua kub nyhiab loj muaj qhov tseem ceeb ntawm kev lag luam thiab lub neej ntawm lub inverter. Thaum siv cov yeeb nkab ua kom txias thiab txias, hauv qhov siv, yuav tsum tau xyuam xim rau lub installation thiab kev siv ntawm qhov chaw, tus inverter yuav tsum muab tso rau hauv horizontally, yog nruj me me "rov qab", txwv tsis pub rau cua sov dissipation; tseem xav tau kom tsis tu ncua ntxuav lub plhaub ntawm lub plhaub ntawm lub plhaub, ces nws kuj yuav cuam tshuam tshav kub.
3. Kev tiv thaiv kev tiv thaiv: Cov kwj hauv qhov tsuas yog siv cov zis hluav taws xob ntawm cov pa roj carbon monoxide PWM, thiab cov zis tam sim no nyob ze rau lub sine wave, tab sis lub tswv yim tam sim no tsis yog tus qauv sine yoj thiab muaj kev sib haum xeeb ntawm ntau yam. Vim li no, txoj kev tiv thaiv kev tiv thaiv yog siv. Ua rau kev tsis haum los yog kev cuam tshuam rau kev cuam tshuam, yog li yuav tsis siv cov hluav taws xob hauv hluav taws xob, yuav tsum siv lub tshuab tua hluav taws los tua, tab sis tam sim no qhov kev pub mov pub mis yog kev siv cov pa luam yeeb tsis haum, inverter Tom qab ntawd, lawv feem ntau ua rau hluav taws xob qis qe. Feem ntau ntawm txoj haujlwm tam sim no muaj feem xyuam nrog cov lag luam uas muaj zog-siab nyob rau hauv txoj hauv kev nrog qhov kev tiv thaiv kev tiv thaiv ntawm kev tiv thaiv kab mob kom tshem tawm cov kev yuam kom muaj "glitches" nyob rau hauv lub teeb liab; ob, qhov kev tiv thaiv tawm tsis muaj peev xwm yuav ua kom tsis txhob raug txo kom qis mus raws li 30mAS (millisecond) txoj cai. , Ua kom nrov loj rau lub sij hawm tiv thaiv tawm kom cov khoom seem tsis hloov. Tsis tas li ntawd, qhov kev yoojyim hauv kev xa khoom pub mus rau qhov kev tiv thaiv tawm, tab sis muaj feem xyuam nrog lub zog ntawm cov khoom siv hluav taws xob, tab sis tseem nrog cov kev hloov pub rau cov tub lag luam sib txawv yog qhov sib txawv, peb yuav tsum ua tib zoo saib cov lus qhia. Qee zaum, muaj ib qho teeb meem nrog txoj kev tiv thaiv ntawm qhov kev hloov pub, uas tej zaum yuav ua rau lub hwj chim tawm mus ncig. Lub sijhawm no, tus neeg siv feem ntau siv tus inverter los tham txog nws. Yog li, nws yuav tsum ua tib zoo xyuas, tshawb xyuas qhov ua rau, thiab kho nws kom zoo. Kev siv lub inverter, nws yog ib qho tseem ceeb uas yuav tsum tau saib xyuas kom zoo grounding, qhov sib tshooj ntawm cov kab hauv av kom tau raws li qhov yuav tsum tau ua, thaum lub qhov av electrode yuav tsum tau zoo grounded, av tsis ua haujlwm yog tsawg dua 3 ohms, ib qho kev cuam tshuam rau kev cuam tshuam kev cuam tshuam.
