Yuav ua li cas siv tus mullamalat kom pom qhov zoo ntawm inverter?
Nws yuav tsum raug sau tseg tias rau kev nyab xeeb ntawm tus kheej, nws yog ib qho tsim nyog los xyuas kom meej tias lub tshuab hluav taws xob tawm thiab cov zis hluav taws xob koj tau muab tshem tawm ua ntej ua haujlwm! Ua ntej, teeb tsa ntau ntau rau "diode" iav, thiab tom qab ntawd siv cov kev ntsuas liab txhuas txhuas txhuas coj los ntes cov kauj ruam hauv qab no:
Qhov kev sib tw dub coj ua kov tus ncej tsis zoo p (+) ntawm DC npav, thiab kev ntsuas liab txhuas kov kov R, S, TT, sau cov ntawv pom ntawm tus nqi ntawm multimeter. Tom qab ntawd txoj kev ntsuas liab txhuas kov n (-}}}}}}}}}}}}}}}}}}}} Txoj kev sib tw dub R, thiab sau cov zaub uas muaj nuj nqis ntawm cov nqi multimeter. Yog hais tias muaj rau cov zaub muaj nuj nqis yog qhov tseeb sib npaug, nws qhia tau tias tsis muaj teeb meem nrog DIode Reverification lossis qhov muag}} pib respease ntawm zaus hloov pauv. Txwv tsis pub, lub rectifier module los yog muag - pib resistector ntawm txoj haujlwm sib raug puas tsuaj, thiab cov tshwm sim tsis muaj zaub.
Txoj kev ntsuas liab txhuas kov cov ncej tsis zoo p (+) ntawm DC npav, thiab cov duab dub, thiab sau cov nqi tso rau ntawm cov nqi multimeter. Tom qab ntawd qhov kev ntsuas dub ua kov n (-}}}}}}}}), thiab sau cov zaub uas muaj nuj nqis ntawm tus multimeter. Yog tias 6 tso saib 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, lub igbt inverter module ntawm txoj hauj lwm sib haum yog puas ntsoog, thiab qhov tshwm sim tsis muaj qhov tsim tawm lossis lub tswb ua txhaum.
Siv cov zaus hloov kho kom tsav lub cev muaj zog uas muaj zog nrog lub zog tsis muaj -}}}}}}}}
Thaum lub sijhawm tus txheej txheem no, siv cov ammeter los kuaj qhov tsis muaj - phoo tam sim no ntawm lub cev muaj zog. Yog tias tsis muaj {{2} Kev tsis ruaj khov thaum lub zaus tsawg dua thiab tuaj yeem tsis hloov pauv, nws yog qhov kev hloov pauv zoo.

Kev Txiav Txim ntawm AC thiab DC cov khoom - Lub Xeev Relay ntawm DC cov lus qhia txog "+" cov cim, thiab "DC tsim tawm" tau sau tseg. Rau ib qho AC khov kho - lub xeev relay, tsuas yog cov "+ {{{{{{{}" {{{{
