Cov lus qhia kom siv tau siv ntau ntau los ntsuas qhov zoo ntawm cov inverter
Hauv cov txheej txheem tsim qauv ntawm cov hluav taws xob hluav taws xob, engersers inevitably xav tau ntau ntsuas ntsuas ntsuas ntsuas ntsuas. Cov kws ua encersers paub hais tias ib tug multively tuaj yeem ntsuas DC tam sim no, AC Voltage, thiab DC voltage. Thiab cov zaus hloov pauv yog lub cuab yeej uas tswj hwm AC motors los ntawm kev hloov kho lub cev muaj zog ntawm lub cev muaj zog. Kab lus no yuav piav qhia yuav ua li cas siv ntau qhov kev ntsuas ntsuas qhov zoo ntawm ntau zaus converter.
Nws yuav tsum raug sau tseg tias rau kev nyab xeeb ntawm tus kheej, lub tshuab yuav tsum tau tsav tawm thiab cov kab hluav taws xob cov hluav taws xob yuav tsum tau muab tshem tawm ua ntej ua haujlwm! Ua ntej, teeb tsa ntau ntau rau "txoj haujlwm thib ob" txoj haujlwm, thiab tom qab ntawd siv cov nuj nqis liab thiab dub ntawm cov kauj ruam hauv qab no:
Qhov kev sojntsuam dub sib cuag tus ncej tsis zoo P (+) ntawm DC npav, thiab cov kev sojntsuam liab, thiab cov kev sojntsuam liab, thiab sau cov nqi uas muaj cov nqi ntawm kev sib xyaw. Tom qab ntawd kov cov kev sojntsuam liab nrog n (-), thiab kov cov kev sojntsuam dub nrog r ua ntu zus S, T, sau cov ntawv pom ntawm tus nqi ntawm multimeter. Yog hais tias muaj rau kis muaj nuj nqis yog qhov tseeb sib npaug, nws qhia tau tias tsis muaj teeb meem nrog Rectifier lossis muag pib tiv taus cov inverter diode. Txwv tsis pub, yog tias lub rectifier module lossis mos pib resistort ntawm qhov chaw sib xws yog puas ntsoog, qhov tshwm sim yog: tsis muaj zaub.
Qhov kev sojntsuam RED cov neeg tsis zoo P (+) ntawm DC npav, thiab cov kev sojntsuam dub, hu rau koj nyob rau hauv Clequence V, W, sau cov nqi uas pom muaj tus nqi rau ntawm multimeter. Tom qab ntawd kov cov kev sojntsuam dub nrog n (-), thiab kov cov kev sojntsuam liab nrog u hauv kev sib tw V, W, sau cov ntawv pom ntawm tus nqi ntawm pultimeter. Yog hais tias muaj 6 qhov tseem ceeb muaj nuj nqis yog qhov tseeb sib npaug, nws qhia tau tias tsis muaj teeb meem nrog IGBT inverter module ntawm zaus hloov pauv. Txwv tsis pub, yog tias lub IGBT inverter module ntawm txoj haujlwm sib haum yog puas, qhov tshwm sim yog: tsis muaj qhov tsim tawm lossis ua txhaum.
Siv kev hloov pauv zaus kom tsav lub cev muaj zog asynchronous nrog txuam hluav taws xob rau ntawm qhov chaw ua haujlwm tsis muaj cov haujlwm f los ntawm 50Hz mus rau qhov qis qis.
Thaum lub sijhawm tus txheej txheem no, siv cov ammeter txhawm rau txhawm rau txhawm rau ntes tsis-thauj khoom tam sim no ntawm lub cev muaj zog. Yog tias tsis muaj-thauj tau tam sim no tseem nyob ruaj khov thaum lub zaus tsawg dua thiab tuaj yeem nyob twj ywm tsis hloov pauv, ces nws yog qhov hloov pauv zoo.
Qhov tsawg kawg nkaus zaus tuaj yeem suav raws li hauv qab no: (synchronous ceev - rated ceev) x ncej,} × 2} {hz.
Tsis muaj teeb meem nrog lub ntsej muag muag muag uas muag, txwv tsis pub cov ntaub ntawv hluav taws xob lossis muag pib resistor ntawm txoj haujlwm sib raug puas tsuaj, thiab tsis muaj zaub.
Qhov kev sojntsuam RED cov neeg tsis zoo P (+) ntawm DC npav, thiab cov kev sojntsuam dub, hu rau koj nyob rau hauv Clequence V, W, sau cov nqi uas pom muaj tus nqi rau ntawm multimeter. Tom qab ntawd kov cov kev sojntsuam dub nrog n (-), thiab kov cov kev sojntsuam liab nrog u hauv kev sib tw V, W, sau cov ntawv pom ntawm tus nqi ntawm pultimeter. Yog hais tias muaj 6 qhov tseem ceeb muaj nuj nqis yog qhov tseeb sib npaug, nws qhia tau tias tsis muaj teeb meem nrog IGBT inverter module ntawm zaus hloov pauv. Txwv tsis pub, yog tias lub IGBT inverter module ntawm txoj haujlwm sib haum yog puas, qhov tshwm sim yog: tsis muaj qhov tsim tawm lossis ua txhaum.
Siv kev hloov pauv zaus kom tsav lub cev muaj zog asynchronous nrog txuam hluav taws xob rau ntawm qhov chaw ua haujlwm tsis muaj cov haujlwm f los ntawm 50Hz mus rau qhov qis qis.
Thaum lub sijhawm tus txheej txheem no, siv cov ammeter txhawm rau txhawm rau txhawm rau ntes tsis-thauj khoom tam sim no ntawm lub cev muaj zog. Yog tias tsis muaj-thauj tau tam sim no tseem nyob ruaj khov thaum lub zaus tsawg dua thiab tuaj yeem nyob twj ywm tsis hloov pauv, ces nws yog qhov hloov pauv zoo.
